I have been advising my patients to exercise, keep active, and walk as long as they can in order to stay mobile and healthy. However, seniors often tell me activities that require prolonged walking is limited by ankle pain from arthritis. They often ask, “What is arthritis of the ankle?” How does it happen? What can I do about it?

Three Most Common Forms of Arthritis of the Ankle

• Osteoarthritis – is also known as degenerative arthritis. It is the most common form of arthritis in the ankle. It is usually a gradual, slow and progressive process of “wear and tear” to the cartilage in the ankle joint which eventually wears down to the bony joint surface. It is most often found in middle-aged and older people and in weight bearing joints such as the hip, knee and ankle.
• Rheumatoid Arthritis (RA) – is a form of inflammatory arthritis in which many joints of the body can be affected. It is very destructive to the cartilage, joint and tissues surrounding the joint. It can occur at any age and usually affects multiple joints.
• Post-Traumatic Arthritis- is a form of arthritis that can occur following a trauma or injury to the ankle. It is a form of osteoarthritis that is triggered years after a fracture or ligament injury. Those of you who know Jim Gouldsbury, Jr., a local letter carrier for the United State Postal Service, may know the effects of prolonged weight-bearing on injured limp. Jim suffered from an ankle injury several years ago and worked in a job that requires constant weight-bearing. He is now suffering from traumatic arthritis at a relatively young age.

Symptoms of Arthritis

• Pain - usually occurs gradually. However, a sudden onset can occur, especially associated with a sudden twist or fall. Pain is often worse in the morning and improves with movement. Changes in the weather or barometric pressure can cause pain associated with arthritis.
• Swelling – can swell after increase activity at the end of the day.
• Stiffness – is more noticeable in the morning and improves with movement. However, overuse can create more pain and swelling and lead to stiffness also.
• Weakness – from disuse associated with pain and can lead to occasional buckling of the ankle when walking or climbing steps.                 
• Loss of Function- is associated with pain, swelling, weakness and stiffness which limits walking, stair climbing etc.

Diagnosis

Your family physician will examine your ankle to determine if you have arthritis. In more advanced cases you may be referred to a specialist such as a podiatrist,  orthopaedic surgeon or rheumatologist for further examination and treatment. X-rays will show if the joint space between the bones in the ankle is getting narrow from wear and tear arthritis. If rheumatoid arthritis is suspected, blood tests and an MRI may be ordered. The diagnosis will determine if you problem if minor, moderate or severe.

Treatment

Conservative Treatment

In the early stages your treatment will be a conservative, nonsurgical approach, which may include; anti-inflammatory medication, orthopedic physical therapy, exercise, activity modifications, supplements, bracing, etc. You and your family physician, podiatrist, orthopedic surgeon or rheumatologist will decide which choices are best.

• Anti-inflammatory Medications: such as aspirin, acetaminophen or ibuprofen to reduce pain and swelling in the joint. 
• Orthopedic Physical Therapy: such as heat, cold, ultrasound, electrical stimulation, joint mobilization, range of motion exercises, strengthening exercises, partial weight bearing aerobic exercises.
• Activity Modifications: such as eat well and lose weight, doubles tennis instead of singles, sitting or lying leg exercises instead of standing, walk instead of run, soft bed treadmill instead of hard surfaces, avoid squatting, kneeling, and bending.
• Supportive Devices: such as ankle sleeves, light bracing, orthothics (inserts), use good running shoes for exercise and walking, use good quality supportive shoes for work/dress.

Conservative But More Aggressive Treatment

• Corticosteroids: stronger anti-inflammatory medications than those above which are injected directly into the ankle joint.
• Viscosupplementation: a type of synthetic fluid, injected into the ankle joint and designed to imitate the joint fluid of the ankle to promoted healing and mobility.
• Glucosamine and Chondroitin: supplements taken orally to control the pain of osteoarthritis and promote healing.
• Rheumatoid Medications: specifically designed  for RA

Surgical Treatment

When conservative measures no longer succeed in controlling pain and deformity, improving strength and function then more aggressive treatment may be necessary.

• Arthroscopic Surgery: uses a scope to clean and repair damaged tissues inside the ankle joint.
• Fusion Surgery: the ankle bones are surgically fused together to limit movement of painful joint.
• Total Ankle Replacement: replaces severely damage joint surfaces with metal and/or plastic.

SAFE RETURN TO DRIVING AFTER INJURY OR SURGERY

I enjoy the privilege of working with people recovering from a wide variety of medical conditions. Many of these conditions can directly affect activities of daily living, particularly, the ability to drive safely: orthopedic and sports injuries, fractures, sprains and strains, joint replacements, hip fractures, shoulder and elbow surgeries and spinal fusions. Despite the many different types of problems, there is one question that is invariably asked, “When can I return to driving?” Unfortunately, the answer is not as simple as the question because it depends on many factors. Furthermore, the implications, such as a serious accident causing further damage to the injury or surgical site or harm to someone else, are significant and possibly critical. So, the next time you ask your physician this question, please follow instructions and be patient…remember, it could be your child or grandchild running into traffic to chase a ball and you would want the driver to be at optimal function to apply the brakes!

Impact of Not Driving

In our culture, the inability to drive has a significant impact on lifestyle and livelihood. A study published in the Journal of Bone and Joint Surgery, found that 74% of those unable to drive due to injury or surgery are dependent on family and most of the remainder depend on friends. 4% of those unable to drive have no help at all and more than 25% suffer major financial hardship.

The report also found that family physicians, orthopedic surgeons, podiatrists, and physical therapists are keenly aware of this dilemma but often fail to communicate effectively to patients about driving. Most medical professionals express serious concerns about liability regarding return to driving following an injury or surgery. They feel that there is a lack of data to support decisions and inadequate communication among each other. They agree that they must do a better job communicating with patients and their families so they can better prepare for a period of time during their recovery in which they cannot drive.

Recent studies published in the Journal of the American Academy of Orthopaedic Surgeons (JAAOS) and the Journal of Foot and Ankle Surgery (JFAS),determined that there are two significant components in the decision of safely returning to driving after an injury or surgery; the time required for healing and the time required for a return of function. Additionally, it was found that those wearing a surgical shoe or walking boot demonstrated a significantly slower braking response time even in healthy/non-injured individuals wearing the shoe/boot.

Time for Adequate Healing

During the time required for healing, in addition to the fear of an additional trauma from a motor vehicle accident to the healing body part, there is a general concern about the potential damage that may come from over using the body part to drive before it is adequately healed. For example, a healing fracture in the right lower leg might be compromised or delayed if one must suddenly and forcefully apply the brakes. Also, during this time, it is not unusual for post-injury or post-surgery patients to use pain medications, including narcotics. This will also compromise judgment and reaction time while driving.  

Time for Adequate Function

Most orthopedic conditions heal in 6 to 8 weeks. However, as many of you may fully know, once a cast or splint is removed, you are not ready to run or jump. Depending on the severity of the injury, it may take many weeks of aggressive physical therapy to regain strength, range-of-motion, agility and dexterity to function at a safe level for a full return to daily activities, including driving.

Driving Requires the Whole Body

The current research reinforces the fact that driving safely requires good function of the entire body. For example, just because you broke your shoulder bone but did not fracture your right leg does not mean that you are able to drive safely. Wearing a sling after arm surgery also compromises driving. First, you need a stabilized and healed injury prior to driving. Then, you must work in rehab to make modifications to return to safe driving. Apply the same scenario to injuries or surgery to the spine (neck and lower back).

GENERAL GUIDELINES: RETURN TO NORMAL BRAKING REACTION TIME AFTER SURGERY (JAAOS)

*Based on research using driving simulators

7 TIPS TO KNOW WHEN YOU ARE READY TO DRIVE:

1. You have physician’s approval that you are healed enough not to do any damage to the injury.
2. You can use your arms to touch your forehead and opposite shoulder without significant pain.
3. You can walk with minimal pain and minimal limp.
4. You can put 50% of your total weight on the involved leg (especially the right).
5. You have adequate range of motion at the hip and knee (bend the hip 70-90 degrees, extend your knee to -10/-5 degrees and bend your knee to 80-90 degrees without pain).
6. You can drive in empty parking lot and practice without difficulty.
7. You are wearing a surgical shoe or boot that does not involve surgery or fracture healing (tendonitis or plantar fasciitis) and with your physician or podiatrists approval, the device can be removed without causing pain upon seated weight-bearing and gas/brake simulation.

Remember, every case is unique and there is no substitute for communication with your orthopedic surgeon, podiatrist, family physician and physical therapist.

Visit your doctor regularly and listen to your body.     

Keep moving, eat healthy foods, exercise regularly, and live long and well!

Part II of II  

Introduction:

As most sports enthusiasts know, Aaron Rodgers, former Green Bay Packer quarterback and recent New York Jets QB (for just over a minute and half) suffered a season ending injury when he tore his Achilles tendon in the first game of the 2023/24 NFL season. Since then, I have been answering many questions from patients and sports fans about the nature of the Achilles Tendon rupture injury, recovery, and how to prevent it.

As the days continue to get shorter and temperatures begin a slow steady decline, athletes and exercise enthusiasts will work harder to warm-up and exercise during the winter months. A little caution and preparation are in order to avoid muscle/tendon strain, or worse yet, muscle/tendon tears, especially Achilles Tendon rupture. The Achilles tendon is one of the more common tendons torn.

This is the second of two columns on Achilles tendon rupture. Last week, I discussed the definition, sign and symptoms of the problem. This week will present examination, treatment and outcomes.

Achilles Tendon Rupture Exams and Tests:

A thorough history and physical exam is the first and best method to assess the extent of the injury and determine accurate diagnosis. While a complete tear is relatively easy to determine, a partial or incomplete tear is less clear. Ultrasound and MRI are valuable tests in these cases. X-rays are not usually used and will not show tendon damage.

Achilles Tendon Rupture Treatment:

Initial First Aide Treatment:

• Remember RICE!
  • Rest the involved tendon/ankle/heel. Pain is telling you NOT to move the tendon. Use crutches and limit weight bearing on the involved foot until you are seen by a medical professional.
  • Ice the tendon/ankle/heel. Control the swelling and spasm.
  • Compress the ankle/foot and control the swelling but do not wrap it too tightly.   
  • Elevate the ankle/foot to allow gravity to help control swelling.
• Medication: Depending on your tolerance and previous experience, choose an over-the-counter nonsteroidal anti-inflammatory drug for pain and inflammation such as ibuprofen. Discuss with your primary care physician and pharmacist.
• Note: If symptoms persist, see your primary care physician, podiatrist or orthopedic specialist to determine the extent of your injury. Do not delay too long to seek medical attention because early intervention will produce the best outcomes.

Early Treatment - Conservative:

• Protection – the torn tendon must be protected from further damage or stretching by using a heel lift to put the tendon on slack. In more involved cases, a removable walking cast/boot may be used for additional protection.
• Physical Therapy -  
  • Controlled Motion – gentle controlled motion to the ankle, foot and toes to control swelling and prevent stiffness is usually encouraged.
  • Modalities – such as ice, compression, ultrasound, massage, electrical stimulation may also be employed for pain and swelling.
  • Gradual Resistance Exercises – in the case of a partial tear, once healing begins, resistance exercises may be introduced gradually. These exercises will require the supervision of a physical therapist to emphasize resistance in a lengthening position (to be described under “prevention” later in this column).

Surgery:

Consultation with an orthopedic or podiatric surgeon will determine the best treatment option for you. When conservative measures fail and for tendons completely torn, surgical intervention is usually considered to be the best option with a lower incidence of re-rupture. Surgery involves reattaching the two torn ends. In some instances, a graft using another tendon is required. A cast or walking boot is used post-operatively for 6-8 weeks followed by physical therapy. 

Outcome:

Most people return to close to normal activity with proper management. In the competitive athlete or very active individual, surgery offers the best outcome for those with significant or complete tears, to withstand the rigors of sports. Also, an aggressive rehabilitation program will expedite the process and improve the outcome. Walking with full weight on the leg after surgery usually begins at 6 -8 weeks and often requires a heel lift to protect the tendon. Advanced exercises often begin at 12 weeks and running and jumping 5-6 months. While a small bump remains on the tendon at the site of surgery, the tendon is well healed at 6 months and re-injury does not usually occur.

Achilles Tendon Rupture Prevention:

Prevention of muscle and tendon tears is critical for healthy longevity in sports and activities. In addition to the Achilles tendon, the tendons of the quadriceps (knee) and rotator cuff (shoulder) are also vulnerable. A comprehensive prevention program includes: gradual introduction to new activities, good overall conditioning, sport specific training, pre-stretch warm-up, stretch, strengthening, proper shoes, clothing, and equipment for the sport and conditions. Also, utilizing interval training, eccentric exercise (lowering body weight slowly against gravity – Photo 1) and proprioceptive and agility drills are essential (Photos 2 & 3). 

In PHOTO 1a & 1b: Eccentric Lowering and Lengthening: for the Achillies tendon during exercise. Beginning on the ball of both feet (1a), bend the strong knee to shift the weight onto the weak leg (1b). Slowly lowering the ankle/heel to the ground over 5-6 seconds. Repeat.

In PHOTO 2: Proprioceptive Training: for the Achillies tendon. Standing on a Bosu Ball while exercising the upper body (for example, biceps curls, shrugs, rows, lats) while maintaining balance on the ball.

PHOTO 3: Agility Drills: for the Achilles tendon involves stepping through a “gait ladder” in various patterns and at various speeds.

Introduction

 As most sports enthusiasts know, Aaron Rodgers, former Green Bay Packer quarterback and recent New York Jets QB (for just over a minute and half) suffered a season ending injury when he tore his Achilles tendon in the first game of the 2023/24 NFL season. Since then, I have been answering many questions from many about the nature of the injury and how to prevent it.

As the days continue to get shorter and temperatures begin a slow steady decline, athletes and exercise enthusiasts will work harder to “fit in” a warm-up before running or other activities during the winter months. But, no matter how limited time is, skipping the warm-up is risky. This time of year, one can expect to feel a little cold and stiff, especially if you are over 40, and therefore a little caution and preparation are in order to avoid muscle/tendon strain, or worse yet, muscle/tendon tears. The more commonly torn tendon is the Achilles tendon . Prevention of muscle tears, including the Achilles tendon includes; gradual introduction to new activities, good overall conditioning, sport specific training, pre-stretch warm-up, stretch, strengthening, proper shoes, clothing, and equipment for the sport and conditions.

Tendon Injury and How It Occurs

A muscle contracts to move bones and joints in the body.  The tendon is the fibrous tissue that attaches muscle to bone. Great force is transmitted across a tendon which, in the lower body, can be more than 5 times your body weight. Often, a tendon can become inflamed, irritated, strained or partially torn from improper mechanics or overuse. Although infrequent, occasionally tendons can also snap or rupture. A tendon is more vulnerable to a rupture for several reasons such as a history of repeated injections of steroids into a tendon and use of medications such as corticosteroids and some antibiotics. Certain diseases such as gout, arthritis, diabetes or hyperparathyroidism can contribute to tendon tears. Also, age, obesity and gender are significant risk factors as middle-aged, overweight males are more susceptible to tendon tears. Poor conditioning, improper warm-up and cold temperatures may also contribute to the problem.  

Tendon rupture is very painful and debilitating and must not be left untreated. While conservative management is preferred, surgical management is usually required for complete tears. The purpose of this column is to present the signs, symptoms and management of Achilles tendon ruptures.

Achilles Tendon

The Achilles tendon (also called the calcaneal tendon), is a large, strong cordlike band of fibrous tissue in the back of the ankle. The tendon (also called the heel cord) connects the powerful calf muscle to the heel bone (also called the calcaneus). When the calf muscle contracts, (as when you walk on the ball of your foot), the Achilles tendon is tightened, tension is created at the heel and the foot points down like pushing a gas pedal or walking on tip of your toes. This motion is essential for activities such as walking, running, and jumping. A partial tear of the tendon would make these activities weak and painful, while a full tear through the tendon would render these activities impossible.      

With age, the Achilles tendon (and other tendons) gets weak, thin, and dehydrated, thus making it prone to inflammation, degeneration, partial tear or rupture. The middle-aged weekend warrior is at greatest risk. A full or complete tear (Achilles tendon rupture) usually occurs about 2 inches above the heel bone and is associated with a sudden burst of activity followed by a quick stop or a quick start or change in direction, as in tennis, racquet ball, and basketball.

In some instances, the tendon can be injured by a violent contraction of calf when you push off forcefully at the same time the knee is locked straight as in a sudden sprint. Other times, the tendon is injured when a sudden and unexpected force occurs as in a trip off a curb or sudden step into a hole or a quick attempt to break a fall.

Achilles Tendon Rupture Symptoms

• Pain – sudden and severe pain in the back of the ankle or calf that feels like being hit by a rock or gun shot.
• Pop – sometimes it is reported that a loud pop or snap is heard when the tendon tears.
• Divot Deformity – sometimes a depression or indentation in the tendon is seen or felt with a bulbous area above or below the tear.
• Black and Blue – it is common to have bleeding after tearing the muscle or tendon with black and blue color and bruising the night or day after the injury.
• Swelling – in addition to swelling in the tendon area of the tear, sometimes swelling will be prominent in the ankle and foot.
• Stiffness – loss of movement due to swelling and weakness.
• Weakness – inability to “push off” on the injured foot when walking or climbing steps.
• Loss of Function – difficulty with daily activities that require walking, ascending inclines, climbing stairs, or jumping.

Jury Out on Value for Running Performance

Runners will attempt to conquer 26.2 miles from Forest City to downtown Scranton in the 26th Annual Steamtown Marathon this Sunday. Participants may want to consider new research that suggests the use of compression socks may prevent post race blood clots.

Completing the long and arduous 26.2 mile journey is not an easy task. In fact, the mechanical and physiological toll on your body is tremendous; from painful joints, muscles, tendons, to black and blue toes. Not so obvious, however, is the damage to your deep veins and tissues of the circulatory system. New research indicates that strenuous endurance exercise, such as marathon running, stimulates the clotting mechanisms in your body in response to the multiple micro traumas sustained over 2 or more hours. While most healthy athletes will naturally heal from post exercise clot formation, others may be at risk…those traveling more than 1 hour (by car, bus, train or plane). The risk increases substantially for those with a longer period of travel/sitting post-race, history of previous trauma, blood clots or have the genetic predisposition for clot formation.

What Are Compression Socks? How Do They Work?

Compression socks are familiar to most people as the tight knee-high support stockings worn after a surgical procedure such as a knee or hip replacement to prevent blood clots. They are made with a special fabric and weave design to provide graduated compression (stronger compression at foot and ankle and less at the top of the sock) to promote better circulation and movement of fluids from the foot, ankle and calf back to the upper leg and ultimately the heart. Compression socks work similarly in runners. As the stagnant fluid with lactic acid and other byproducts of exercise is removed from the space, fresh blood, nutrients and oxygen is replaced to foster healing of micro damage to tissue and promote more efficient use of the muscles.

Is There Any Research?

The Journal of Strength and Conditioning Research published a study that found wearing compression socks improved running performance. However, similar studies have failed to support this claim. One finding that has been repeatedly supported in the literature, including The British Journal of Sports Medicine, found that compression socks worn in soccer players and runners improved the rate and magnitude of recovery. Moreover, recent studies, including a study with the Boston Marathon, have demonstrated the reduction in clotting mechanisms in those wearing compression socks AFTER the marathon, as compared with those wearing “sham” socks. Benefits seem to be less obvious for short duration activities or when running 10km or less.

Conclusion

In conclusion, only time will tell if compression socks will improve performance in runners will or be merely a fad based on placebo or true fact supported by scientific research. Based on current wisdom, these socks may offer value and benefit AFTER activities of long duration (more than 1 hour) or long distance running (more than 10km) to expedite the recovery from exercise-induced blood clot formation, muscle soreness from the accumulation of lactic acid and other muscle damage byproducts.

It is this author’s opinion that this product is worth a try. However, whenever you try something new for your sport, trials should occur during practice and if successful used during competition. Consider trying a lower compression to begin (the socks come in different degrees of compression). Even if one is hesitant to use the product while running, it appears the greatest value of the sock is after a prolonged training session or competition to reduce exercise-induced muscle soreness and prevent blood clots, especially in athletes at risk for clotting and those traveling for an hour or more after the race. Additionally, in view of the fact that some studies which showed only minimal to moderate improvement in well-trained athletes, it may be that those in greater need, such as deconditioned individuals attempting to begin a fitness program and novice weekend athletes, may benefit more from compression socks than elite athletes.   

TAKE HOME: Runners, cyclists, triathletes, soccer players and others participating in endurance sports should consider compression socks, if not during the activity, certainly following the activity for 24 to 48 hours…especially those at risk for blood clots and those traveling for more than one hour after the race.

Sunday consider trying compression socks and see if they work for you during and more importantly, after your long training runs.

Fall is here, cross-country running season has begun and the 26^th Steamtown Marathon is only a few weeks away! With that in mind, running injuries, some very specific to women, are on the increase…

While driving to or from work have you noticed more local running enthusiasts in the past few years? Moreover, have your noticed that most of the runners are women? Scranton Running Company has contributed to NEPA’s participation in a national trend; more women are engaged in running than men! Female runners account for 9.7 million runners (57%) while 7 million males run on a national level.

With this surge, the female runner has been subjected to a host of related injuries, including shin splints, which often lead to stress fractures. New research has found that stress fractures may be related to the loss of weight and body mass associated with the sport.

A recent study from Ohio State University found that female runners with a Body Mass Index (BMI) below 19 may have a higher risk of developing stress fractures than women with a BMI of 19 or above. Furthermore, the study also found that these women took longer to recover from these injuries.

According to Timothy Miller, MD, “When body mass index is very low and muscle mass is depleted, there is nowhere for the shock of running to be absorbed other than directly into the bones. Until some muscle mass is developed and BMI is optimized, runners remain at increased risk of developing a stress fracture,”

The study also found that female runners with a BMI of 19 or higher with severe stress fractures required 13 weeks to recover from their injuries and return to running. Runners with a BMI lower than 19, however, took more than 17 weeks to recover.

They concluded that women should know their BMI and consult with a medical professional to maintain a healthy number. Additionally, women should cross-train and include resistance training to improve the strength and muscle mass of the lower extremities to prevent injury.

The current BMI wisdom, according to the National Institutes of Health, is 19.8 for men and 24 for women, however, strong and competitive women tend to have a BMI of 26. A BMI of 18 is considered malnourished.

What is BMI?

Body mass index (BMI) is a measure of body fat based on height and weight of adult men and women over 20 years of age, according to the National Institutes of Health.

BMI = (weight in pounds / height in inches squared) X 703)

Example 1: a person who weighs150 pounds and is 68 inches (5 feet 8 inches) tall has a BMI of 22.8

Example 2: a person who weighs 110 pounds and is 66 inches (5 feet 5 inches) tall has a BMI of 17.7

Underweight      < 18.5%

Normal weight      18.5 to 24.9%

Overweight      25 to 29.9%

Obesity            30 and over

What is a stress fracture?

A stress fracture is fatigue damage to bone with partial or complete disruption of the cortex of the bone from repetitive loading. While standard x-rays may not reveal the problem, a bone scan, and MRI will. It usually occurs in the long bones of the leg, mostly the tibia (shin bone) but also the femur (thigh) and foot. Occasionally, it occurs in the arm.

Who is at risk for stress fractures?

FEMALE RUNNERS WITH BMI LOWER THAN 19 – is a primary risk factor.

10-21% of all competitive athletes are at risk for stress fractures. Track, cross country and military recruits are at greatest risk. Females are twice as likely as males to have a stress fracture. Other athletes at risk are: sprinters, soccer and basketball players, jumpers, ballet dancers are at risk in the leg and foot. Gymnasts are also vulnerable in the spine while rowers, baseball pitchers, golfers and tennis players can experience the fracture with much less frequency in the ribs & arm.           

The problem is much more prevalent in weight bearing repetitive, loading sports in which leanness is emphasized (ballet, cheerleading) or provides an advantage (distance running, gymnastics).

Stress fractures usually begin with a manageable, poorly localized pain with or immediately after activity such as a shin splint. Over time, pain becomes more localized and tender during activity and then progresses to pain with daily activity and at rest.

Other Causes of Stress Fractures

• Overuse, Overload, Over training – is the number one cause. Running too many miles with too much intensity with too much frequency is the perfect formula.
• Inadequate Fitness Level – or activity level prior to the stress fracture. For example, the high school runner takes the summer off and then quickly accelerates his/her program to quickly for cross-country in August/September.
• Poor Biomechanics – when your feet hit the ground the forces are absorbed and transferred to the rest of the body. If the biomechanics of feet are not perfect, then the forces are not absorbed and another body part bears too much force. For example, flat or pronated feet poorly absorb the shock and pull the tendons of the foot and shin.
• Recent Change in Training Schedule – sudden increased intensity or speed
• Recent Change in Running Surface – sudden change to a hard or soft surface
• Recent Change in Footwear – shoes too hard or too soft, too much control or too little control, too much pronation or too much supination
• Overweight – running with an extra 10 pounds and attempting to return to running as a method of weight loss
• Underweight – the underweight female athlete is at high risk for stress fractures. If underweight and have a history of menstral irregularities or and eating disorder, the risk of stress fracture increases significantly
• History of Stress Fractures – makes the athlete two times as likely to have another

Prevention & Treatment

• Maintain Ideal BMI – 24 for female runners
• If Overweight – gradual exercise with diet, not too much too quickly - Mix run & walk every 10 minutes
• If Underweight – improve diet maintain healthy body fat%
• Alternate Training – cross train with non-weight bearing activities: bike, swim, elliptical
• Perform lower body weight training – to strengthen the muscles of the lower body, thighs, knees, ankles, feet.
• Gradually Build Up Fitness Level – wean into activity 1-2 miles, then add ½ mile at a time
• Correct Biomechanics - Orthotics, Running shoes, see a Podiatrist
• Gradual Change in Training Schedule
• Gradual Change in Surfaces – ½ run on soft surface, ½ run on hard surface
• Gradual Change in Foot ware – walk in new shoes first, then run 1-2 miles
• Consult Family Physician/Orthopedic Physical Therapist/Nutritionist
