Stress fractures of the leg and foot

Stress fractures occur in bones undergoing mechanical fatigue. They are the result of excessive repetitive submaximal exercise that creates an imbalance between bone resorption and formation. Fractures usually occur at the site of greatest stress; this is called “cracking”. If this microscopic crack cannot be healed and subjected to further stress, the microdamage will increase and the crack will grow in size. Such an increase can be the cause of a bone fracture at the macroscopic level.

Epidemiology / etiology

An estimated 15-20% of traumatic overuse are stress fractures. These types of fractures are associated with continuous physical activity (such as running or marching). About 50% of stress fractures occur in the tibia; however, a stress fracture can occur anywhere. The foot (especially the second metatarsal bone) is another common site for stress fractures. It is reported that the risk of a stress fracture is 1.5 to 12 times higher for women than for men.

Stress fractures can occur due to a variety of factors, including activity level, bone strength, anti-inflammatory drugs, radiation, nutritional status, osteoporosis, hormonal imbalances, sleep deprivation, and collagen abnormalities. The recurrence of stress fractures depends on bone chemistry, adjacent muscle attachments, vasculature, systemic factors, and athletic activity. Other possible risk factors include age, gender, shoes, and exercise regimen. Female athletes have a high propensity for the sports triad (amenorrhea, eating disorders, and osteoporosis), but hardy male athletes with uncharacteristically low levels of sex hormones are also at risk of stress fractures.

Biomechanically, stress fractures can result from muscle fatigue, which puts excessive stress on the bone. In addition, the position of the elements of the lower extremities presumably influences the risk of stress fractures. Moreover, early studies have shown that low tibial thickness, high degree of external hip rotation, varus ankle and metatarsal position, ankle overpronation, hollow foot, and leg length differences can increase the risk of stress fractures among athletes (data for some factors are ambiguous).

Clinical manifestation

The clinical presentation may vary among patients, and therefore a complete medical history must be obtained to determine the likelihood of a stress fracture. The person may describe the worsening of symptoms over time with activity and not report the specific pattern of the trauma. Initially, pain may appear during activity but then becomes constant. It is important to take into account that the patient may not mention basic information for the physiotherapist about the increase or change in inactivity. A patient in the area of ​​pain localization may have slight swelling and redness, focal or point painful sensitivity (touching with one finger is provided), a difference in the length of the legs, and increased pain when resting on the leg, provoking an antalgic gait. A tuning fork test along the painful area should cause severe pain in the event of a fracture. Athletes, athletes, and military personnel typically suffer from stress fractures. Patient risk increases if adequate rest is not available between training or competition. Young female athletes (within this sample) are more prone to stress fractures due to a triad of factors harmful to bone mass.

Differential diagnosis

Different diagnoses vary depending on the location of the pain. Other possible diagnoses include infection, tumor, constriction syndrome, arthritis, compression nerve injury, medial tibial stress syndrome, and other soft tissue injuries.

Compartment syndrome develops due to pressure inside the muscle sheaths (compartments) of the lower leg, separated by fascial layers. The pressure in the cases can be the result of increased demand for oxygen and, as a result, increased blood flow to the tense muscle. Patients may experience calf cramps, muscle tension, severe pain, drooping foot, and foot paresthesia. Acute crush syndrome is a medical emergency and surgical fasciotomy is the main treatment option.

Medial tibial stress syndrome (MTSS), or split tibia syndrome, suggests periostitis at the junction of the mid-to-distal third of the medial tibia. This syndrome can result from traction on the soleus, flexor digitorum longus, or deep calf fascia. Bone scintigraphy is used to diagnose this syndrome and, if present, shows an increased accumulation of the radiopharmaceutical in the long segments of the bone compared to the foci manifested in stress fractures. During the examination, patients with MTSS may experience mild tenderness along the inner surface of the tibia.

If a stress fracture is suspected after the initial assessment, the physician should refer the patient for diagnosis to confirm or refute the diagnosis. X-rays are commonly used to diagnose stress fractures, despite poor sensitivity. Stress fractures usually do not appear on chest x-ray for 2 to 6 weeks after injury; when they become visible, they appear as bands of enlightenment and may have a cortical induration. Bone scintigraphy is the best diagnostic imaging of stress fractures (fractures are visible 2-3 days after injury).

Survey

When assessing the condition of an adult patient with a stress fracture of the lower limb, a complete medical history is important.

Basic data on the medical history of a person with a stress fracture:

  • Pain when exerted on the leg.
  • The recent increase in activity (high intensity and/or high frequency).
  • Gradual manifestation of the disease.
  • It begins with pain with exertion but progresses to pain at rest and night.

During the physical examination, the specialist can choose the appropriate approach for the injury. An important aspect of the examination includes observation of posture and biomechanics, analysis of gait, leg length discrepancies, tenderness on palpation, and range of motion. Patients with stress fractures usually have tenderness to palpation and swelling in the adjacent soft tissue. According to some reports (Hatch et al., 2007), during the physical examination, it is important to perform a neurological check for sensitivity, vascular condition (capillary filling and heart rate of the lower extremities), examination of the skin for deformities, edema or bruising, and an assessment of the range of motion to determine the presence of a difference in the intensity of pain when moving.

Careful attention should be paid to stress fractures of the scaphoid, one of the most common types of stress fractures of the foot. The special configuration of the foot is a risk factor (however, this sign is not always indicative). Lesions appear both in patients with flat feet and a hollow foot and with a normally developed foot.

Treatment

For stress fractures of the leg and foot, there are surgical and non-surgical treatments. Several factors contribute to the surgery used to treat stress fractures. One factor is the location of the injury (the number of blood vessels in a particular part of the body affects the healing of stress fractures). According to some reports (Brockwell et al.), The talus, navicular bone, medial malleolus, sesamoid bones of the big toe, and the base of the fifth metatarsal bone are identified as high-risk areas, therefore, surgery is recommended in the first place. Conservative methods of treatment are possible for the metatarsus since it has a good blood supply. A complete cessation for 4-8 weeks of the activity causing the stress fracture is recommended. The ability to transfer weight to the injured limb can be determined by the degree of pain of the patient while concentrating the load on it. On the other hand, a medial malleolus fracture is at high risk due to the likely progression to a traumatic fracture. Such fractures can be cured by open reduction and surgery with intraosseous fixation, which leads to faster rehabilitation, compared with the method of conservative therapy (6-8 months).

The patient’s activity profile is another factor considered in the treatment of stress fractures. Sometimes, for highly qualified athletes (who are at particular risk), surgery is considered the best option due to the reduced time interval before returning to normal activity. A systematic review (Torg et al., 2010) did not find a significant difference in outcomes between operative and conservative (no load on the leg, casts) treatments. However, other research shows a difference in the average return time of athletes to the sport; with conservative therapy, rehabilitation takes 5.6 months, and after surgery – 3.8 months. The same study showed an 86% success rate in the treatment of non-displaced stress fractures with a plaster cast (no stress on the leg for 6 to 8 weeks). It was also noted (Torg et al., 2010) that conservative treatment that excludes some degree of stress on the leg (stress on the leg with rest or limitation of activity) leads to healing of injuries (first line of treatment). It is also important for surgery to consider the type of stress fracture if it is displaced, fragmented, or has already been ineffective at conservative treatment. The operation usually involves open reduction with intraosseous screw fixation and sometimes involves a bone implant. fragmented or an ineffective conservative treatment attempt has already been made. The operation usually involves open reduction with intraosseous screw fixation and sometimes involves a bone implant. fragmented or an ineffective conservative treatment attempt has already been made. The operation usually involves open reduction with intraosseous screw fixation and sometimes involves a bone implant.

Physical therapy

The physiotherapy approach involves informing the patient and monitoring changes in inactivity.

At the initial stage of therapy for healing, the pathological stress on the bone should be reduced to a normal physiological level. This usually represents a weakening or no load on the leg for 1 to 2 months, depending on the severity of the fracture. Aquatic exercise, cycling, and upper body workouts will keep the affected lower limb at rest while the patient maintains physical health. After the disappearance of pain in the affected area and with the permission of the doctor, the load on the bone undergoing correction should be resumed. At the end of the rest period, the bone should be protected for proper healing, but muscle atrophy and physical deterioration should be avoided. Pain or discomfort are guiding factors in determining appropriate activity and mechanical stress; the patient may alternate between workouts or other types of physical activity to maintain health, keeping the intensity below that provoking symptoms of the disease. Crutches or other technical aids may be prescribed to relieve stress on the leg or to correct lameness. The lower extremities should be assessed for the correct positioning of their elements, and orthoses should be used to minimize biomechanical risk factors. A period of relative rest and change in activity is extremely important for healing. Progressive muscle strengthening can also help the patient safely return to normal activity after the fracture has healed and maybe a key factor in preventing recurrence. keeping the intensity below the provoking symptoms of the disease. Crutches or other technical aids may be prescribed to relieve stress on the leg or to correct lameness. The lower extremities should be assessed for the correct positioning of their elements, and orthoses should be used to minimize biomechanical risk factors. A period of relative rest and change in activity is extremely important for healing. Progressive muscle strengthening can also help the patient safely return to normal activity after the fracture has healed and maybe a key factor in preventing recurrence. keeping the intensity below the provoking symptoms of the disease. Crutches or other technical aids may be prescribed to relieve stress on the leg or to correct lameness. The lower extremities should be assessed for the correct positioning of their elements, and orthoses should be used to minimize biomechanical risk factors. A period of relative rest and change in activity is extremely important for healing. Progressive muscle strengthening can also help the patient safely return to normal activity after the fracture has healed and maybe a key factor in preventing recurrence. and use orthoses to minimize biomechanical risk factors. A period of relative rest and change in activity is extremely important for healing. Progressive muscle strengthening can also help the patient safely return to normal activity after the fracture has healed and maybe a key factor in preventing recurrence. and use orthoses to minimize biomechanical risk factors. A period of relative rest and change in activity is extremely important for healing. Progressive muscle strengthening can also help the patient safely return to normal activity after the fracture has healed and maybe a key factor in preventing recurrence.

Patient information

Communication will help the patient identify the cause of the stress fracture and avoid recurrence. Running is a common cause of stress fracture; they usually occur when there is an abrupt change in the training regimen, such as an increase in running distance (LE: 2a). The duration of training (year-round) is also associated with the causes of fractures. Therefore, athletes need to evaluate the training program and other factors (type of foot and treadmill). In the study of repeated stress fractures, 60% of the injured athletes were track and field athletes; 40% of them had a hollow foot, compared with 13% of athletes without injuries in the control group. Since there is currently no evidence linking the treatment of hollow foot syndrome with a reduction in the risk of injury, it will be useful for the patient simply to know the type of his foot and the relationship of injuries with personal control of training. High confidence in running injury prevention is only available for controlled training under specific conditions with limited total mileage. Medium-certainty evidence identifies a hollow foot as a risk factor; the least-reliable evidence identifies different leg lengths as a risk factor. Bioprosthetics have the potential to reduce the risk of a stress fracture, but research shows no link to specific anatomical changes. Athletes can also change stride length and running pace to reduce the risk of a stress fracture of the tibia by reducing the amount of stress. The greater the stride length of a person and the higher the running speed, the greater the amount of stress on the tibia. Reducing stride length by 10% and reducing running speed by 1 m / s, resulting in more strides per mile, can help athletes reduce the likelihood of a stress fracture of the tibia. When informing the patient, the focus should be on limiting excessive running distance and abrupt changes in the training schedule. An individually set training program is recommended to help the patient adapt to the stresses while running. When informing the patient, the focus should be on limiting excessive running distance and abrupt changes in the training schedule. An individually set training program is recommended to help the patient adapt to the stresses while running. When informing the patient, the focus should be on limiting excessive running distance and abrupt changes in the training schedule. An individually set training program is recommended to help the patient adapt to the stresses while running.

Conclusion

To prevent stress fractures, the patient (not only the athlete) should gradually increase the frequency and intensity of exercise and avoid a sharp increase in training loads that suppress the bone’s ability to recover in response to stress. The physical therapist should evaluate the patient’s movements within the kinematic chain to determine the specific needs for changes inactivity.

Clinical conclusion

Stress fractures are the result of excessive stress on the bone during physical activity. They can be prevented by gradually changing exercise and doing moderate activities. Stress fractures are generally treated with no stress on the leg and with relative rest. Prospective studies can provide more evidence for factors that can trigger or prevent stress fractures. Such areas of study include minimalistic shoes, foot anatomy, and training parameters.

Note on new research

The latest study was published on two qualified track and field athletes who opted for minimalist footwear, resulting in a stress fracture of the metatarsal bone. With the rise in popularity of minimalist (or imitation barefoot) shoes, this is a topic where further research is needed to determine the potential risks and benefits of using this type of athletic shoe.
