  The prognosis for patients with stress reactions or fractures largely depends on early recognition, injury severity, anatomical location, and adherence to appropriate management strategies. Patients diagnosed in the stress reaction stage—defined by bone marrow edema without cortical disruption—typically experience favorable outcomes with conservative measures, such as activity modification, offloading, and nutritional optimization. Recovery generally occurs within 6 to 8 weeks if mechanical stress is adequately reduced. For patients whose injuries progress to stress fractures, the prognosis varies significantly according to the fracture site and displacement severity. […] Low-risk fractures, eg, those involving the tibia, fibula, or metatarsals, usually heal well with conservative care, including protected weight-bearing and a gradual return to activity. These injuries typically resolve within 6 to 12 weeks, with most patients regaining full function. In contrast, high-risk fractures—including those involving the femoral neck, anterior tibial cortex, and navicular bone—have a greater risk of delayed union, nonunion, or progression to complete fractures if managed inadequately. Such injuries often require prolonged immobilization or surgical intervention. Poor prognostic indicators include ongoing mechanical loading, inadequate nutritional status, osteoporosis, and conditions such as relative energy deficiency in sport (RED-S).

  Stress fractures are common injuries in athletes and military recruits. […] Stress fractures should be considered in patients who present with tenderness or edema after a recent increase in activity or repeated activity with limited rest. […] When stress fracture is suspected, plain radiography should be obtained initially and, if negative, may be repeated after two to three weeks for greater accuracy. […] If an urgent diagnosis is needed, triple-phase bone scintigraphy or magnetic resonance imaging should be considered. […] Surgical consultation may be appropriate for patients with stress fractures in high-risk locations, nonunion, or recurrent stress fractures. […] Prevention of stress fractures has been studied in military personnel, but more research is needed in other populations.

  Stress fractures represent one of the more serious injuries in sport. Following such injuries, return times to sport are often prolonged, and failure to return to sport, chance of re-injury and persisting morbidity are all distinct possibilities. As a group, stress fractures comprise just over 10% of all sport-related injuries, with this figure as high as 30% within certain sports, such as running. The incidence of these injuries is around 1% within recreational athletes, and around 20% within elite level athletes. Around 90% of these injuries are located within the lower limb. Given the financial implications of sport within modern society, both with the substantial revenues associated with professional sport, as well as the economic implications associated with injuries to amateur athletes, the effect of such injuries is considerable.

  Validated prevention interventions for this injury type include the use of shock absorbing insoles as well as the optimisation of athlete fitness prior to the commencement of vigorous exercise. […] Low risk stress fractures are those with a low risk of fracture propagation, delayed union, or non-union, with reliable healing patterns and resolution of symptoms when managed accordingly. This is because they are often located on the compression side of the involved bone, and they develop in an area with robust vascularity. The most common low risk stress fractures are those of the Postero-Medial Tibial Diaphysis, the Metatarsal Shafts, the Distal Fibula, the Medial Femoral Neck, the Femoral Shaft and the Calcaneus. […] Current management protocols advocate conservative management for these stress fractures. The standard treatment is cessation of activities, with restricted weightbearing, until symptoms resolve. Adjuncts such as ultrasound and pneumatic bracing can improve return to sport times. A recent systematic review found that return rates following posterior TDSFs are universally good with all studies reporting return rates of 100%. Return to sport times averaged around 2 mo: Use of pneumatic bracing reduced return times to 1 mo post-injury; use of pulsed ultrasound enabled return to sport immediately post-treatment. Surgical management is reserved for non-unions, with delayed unions treated expectantly; these however are extremely rare due to the well vascularised nature of the postero-medial tibial diaphysis.

  The significance of this injury depends on the location and nature of the fracture: The tibial diaphysis is the commonest reported location and comprises up to three quarters of all stress fractures; other common sites include the metatarsals, the femoral neck, the tarsal naviculus, the fibula, the medial malleolus and the calcaneus. Until the 1980s, much of the stress fracture research had focussed on military cohorts, overlooking cohorts of sporting individuals. Since then, there has been increasing attention paid to the epidemiology, management and outcome of these injuries in sporting individuals, along with optimisation of rehabilitation techniques and promotion of injury prevention. However the optimal management plans for many stress fracture locations have still to be determined. […] At present, there forms a clear division of stress fractures by those which are deemed high risk, with a predilection for fracture propagation, delayed union, or non-union; and those which are deemed low risk, with reliable healing patterns and resolution of symptoms when managed accordingly. Low risk fractures can often be investigated with radiographs alone, and are virtually always managed successfully through conservative management, with rest, activity modification and rehabilitation. High risk fractures often require specialised imaging to better define and quantify the injury, particularly when first line imaging is equivocal; these injuries also may require surgical management, depending on the location of the injury and the response to initial conservative management. As a consequence of this, return to sport is often more challenging with high risk injuries, and this proves particularly demanding with the high level professional athlete. For individual fracture types, the severity of the injury can be graded from the extent of the radiological changes, using either generic or site-specific classifications; such classifications can further guide management planning as well as provide prognostic information regarding return times to sport.

  If symptoms persist following attempted conservative management, surgical intervention should be advised. The available surgical techniques include tibial intra-meduallary (IM) Nailing, compression plating, or drilling of the stress fracture with bone grafting. A recent systematic review found that intra-medullary nailing and compression plating provided the highest return rates and lowest return times of all the surgical treatments available; as such these are the preferred surgical techniques for this injury. This review also found that conservative management of these injuries resulted in decreased return rates to sport compared to surgical management; return to sports rates were 71% for conservative management and 96% for surgical management. Thus, clinicians must remain aware of the benefit of early surgical management in the high level athlete who fails to respond to conservative management. Reported return times to sports for this injury included 7 mo for conservative management and 7 mo for surgical management.

• #12 Lower limb stress fractures in sport: Optimising their management and outcome

  https://www.wjgnet.com/2218-5836/full/v8/i3/242.htm

  For completed fractures, current protocols advocate conservative management (casting) for those which are undisplaced, and surgical management for those which are displaced, normally with an IM Nail. Reported return times for these injuries included 11.5 mo for conservative management and 7 mo for surgical management, with return rates of 67% for conservative management and 100% for surgical management. […] For conservative management, recommended rehabilitation techniques advise activity cessation, with avoidance of heavy loading of the tibia, limited weightbearing with crutches for between 3 to 6 mo. During this time, bracing of the lower limb can be helpful to reduce symptoms. Following this, progression of weightbearing and return to loading activities can be allowed as pain permits. For surgical management, recommended rehabilitation techniques comprise commencement of a progressive weight-bearing programme, within the first week post-operatively, under the care of physiotherapy, with return to full loading activities between 6 and 8 wk post-operatively. With both conservative and surgical management, full level sport should not be commenced until there is clear evidence of clinical and radiological union.

  Although less common, upper extremity stress fractures can occur in persons who participate in sports involving throwing or other overhead motions. […] Persons who participate in repetitive, high-intensity training, such as athletes and military recruits, are at increased risk of developing stress fractures. […] Poor nutrition and lifestyle habits may increase the risk of stress fracture. […] Stress fracture should be suspected in persons with a drastic recent increase in physical activity or repeated excessive activity with limited rest. […] Diagnosing stress fractures can be challenging and warrants consideration of the differential diagnosis, based on location. […] Certain stress fractures may lead to complications, including progression to complete fractures, development of avascular necrosis, or delays in healing or nonunion. […] High-risk stress fractures may warrant consultation with an orthopedist or sports medicine subspecialist. […] In these situations, athletes should be aware of the potential for prolonged recovery or the need for additional interventions, including surgery.

  Overall, long-term outcomes are generally favorable with timely intervention. However, recurrence is common if underlying biomechanical issues or training errors remain unaddressed. Preventive strategies such as progressive training schedules, optimized footwear, sufficient calcium and vitamin D intake, and patient education on symptom recognition are essential for reducing recurrence risk. With early diagnosis and appropriate evidence-based management, most patients can fully recover and resume prior activity levels without significant long-term impairment.

  Stress fractures refer to fractures occurring in the bone due to a mismatch of bone strength and chronic mechanical stress placed upon the bone and form the most severe form of a stress response. […] The site of the stress fracture and suitability for rehabilitation determines treatment. […] Risk factors such as diet, vitamin D, and calcium should be addressed to prevent recurrence. Other factors, such as a gradual return to training and biomechanical evaluation of gait, may be required. Bone density evaluation can be considered in patients with recurrent stress fractures, a family history of osteoporosis, or stress fractures unexplained by exercise activity. […] The use of an MRI grading system for bone stress injuries helps predict recovery time (important, especially for athletes).

• #34 Lower limb stress fractures in sport: Optimising their management and outcome

  https://www.wjgnet.com/2218-5836/full/v8/i3/242.htm

  For completed fractures, current protocols advocate conservative management (casting) for those which are undisplaced, and surgical management for those which are displaced, normally with an IM Nail. Reported return times for these injuries included 11.5 mo for conservative management and 7 mo for surgical management, with return rates of 67% for conservative management and 100% for surgical management. […] For conservative management, recommended rehabilitation techniques advise activity cessation, with avoidance of heavy loading of the tibia, limited weightbearing with crutches for between 3 to 6 mo. During this time, bracing of the lower limb can be helpful to reduce symptoms. Following this, progression of weightbearing and return to loading activities can be allowed as pain permits. For surgical management, recommended rehabilitation techniques comprise commencement of a progressive weight-bearing programme, within the first week post-operatively, under the care of physiotherapy, with return to full loading activities between 6 and 8 wk post-operatively. With both conservative and surgical management, full level sport should not be commenced until there is clear evidence of clinical and radiological union.

  Stress reaction in bone, which may proceed to a fracture, is a significant problem in military recruits and in athletes, particularly long distance runners. […] The use of shock absorbing inserts in footwear probably reduces the incidence of stress fractures in military personnel. There is insufficient evidence to determine the best design of such inserts but comfort and tolerability should be considered. […] Rehabilitation after tibial stress fracture may be aided by the use of pneumatic bracing but more evidence is required to confirm this. […] Stress fractures are a type of overuse injury. They can be very painful and debilitating. Lower limb stress fractures are common in people undergoing military training and in athletes, particularly long distance runners. […] We found some evidence that shock absorbing boot inserts help prevent stress fractures during military training. It is not clear what is the best design to use. […] We found some evidence that pneumatic braces may speed recovery of tibial stress fracture. […] There is limited evidence that following diagnosis of a tibial stress fracture, early mobilisation with the support of a pneumatic brace may accelerate a return to training activity.

  Recommended rehabilitation techniques advise cessation of activities which provoke symptoms, with weightbearing as per pain allows. Some studies advocate immediate return to full weightbearing and sporting activities using an aircast brace, if the patient is completely painfree with the orthotic. […] Validated prevention interventions include the use of shock absorbing insoles, as well as physiological optimisation of the athlete prior to the commencement of vigorous exercise, performing progressive training regimes and limiting training volumes within recommended targets.

  The management strategies of these injuries is constantly developing, and at present, the optimal treatment modality for many stress fracture locations remains unestablished. Even with similar injuries, management and return to sport times can vary for different sport, with prolonged rehabilitation often required to return to repetitive loading sports such as long distance running and jumping. Regular review of the emerging research in this area, in conjunction with pre-existing treatment protocols, is necessary to determine the best way to manage such athletes, and maximise return to sport. In addition to this, given the overuse nature of such injuries, often demonstrating prodromal symptoms and resulting from the presence of risk factors, primary prevention programmes provide the best way of managing such injuries. Ongoing research in this field provides continued resources which can benefit both the athlete and the sports medic to fully maximise the potential of such a practice.
