Unlike a traumatic fracture caused by a single violent impact, a stress fracture occurs progressively: repeated microtrauma creates microcracks in cortical or trabecular bone tissue, which accumulate faster than the bone can repair them. Normal bone remodeling involves prior osteoclastic activation (resorption) followed by osteoblastic formation (deposition of new bone tissue) - when the rate of mechanical loading exceeds this repair cycle, the bone becomes progressively more fragile, leading to cracking or complete fracture. Stress fractures account for 1 to 20 % of sports injuries, depending on the discipline, with a particularly high incidence among long-distance runners, military personnel undergoing intensive training, gymnasts and dancers. The most frequent sites are the tibia (posteromedial part - 50 % of stress fractures), metatarsals (2nd and 3rd - 20 %), fibula, calcaneus, tarsal navicular and femoral neck. A distinction is made between low-risk stress fractures - located on the compression side of the bone, healing spontaneously with rest - and high-risk stress fractures - located on the tension side, exposed to complete displaced fracture with risk of non-union (navicular, femoral neck upper surface, sesamoids, anterior femoral diaphysis, 5th metatarsal base) - requiring urgent specialized orthopedic management. The female athlete's triad - relative energy deficit in sport (RED-S) + dysmenorrhea\/amenorrhea + osteoporosis - is a major risk factor for recurrent stress fractures in sportswomen.\n <\/div>\n\n <h2>Risk factors, location, and diagnosis<\/h2>\n <ul class=\"co-list\">\n <li><strong>Intrinsic and extrinsic risk factors:<\/strong> extrinsic (training-related) factors: rapid increase in training volume or intensity (10 % rule - do not increase weekly mileage by more than 10 % per week) + change of training surface (asphalt + concrete vs. grass + track) + unsuitable or worn-out footwear (>600-800 km) + hasty return to sport after injury or prolonged stoppage; intrinsic (patient-related) factors: low bone mineral density (BMD) - osteopenia + osteoporosis + malnutrition + low calcium and vitamin D intake + RED-S (Relative Energy Deficiency in Sport - formerly athlete's triad) + hypothalamic amenorrhea + eating disorders; biomechanical: lower-limb alignment disorders (genu varum + flat or hollow foot + hyperpronation + leg length discrepancy) + gluteal muscle weakness + calf stiffness + high-impact running pattern (heel strike); bone metabolism: hyperparathyroidism + malabsorption (celiac disease) + chronic hypovitaminosis D + corticosteroid treatment + history of stress fracture (risk \u00d7 2-4); hormonal factors: amenorrhea >3 cycles + hypoestrogenism (progestin-only contraceptive + post-menopause) + male hypogonadism (low testosterone - elite athletes + male RED-S)<\/li>\n <li><strong>Locations according to risk and sport discipline:<\/strong> low-risk fractures (face in compression - usual spontaneous healing under unloading and rest): posteromedial tibia (runners - 2nd most frequent site) + distal fibula (runners) + 2nd-4th metatarsals (runners + dancers) + calcaneus (military + runners) + ribs (rowers + golfers) + clavicle + humerus; high-risk fractures (face in tension - risk of complete fracture + non-union): tarsal navicular (sprint runners + basketball - pain dorsal face midfoot + N sign) + femoral neck superior face (long-distance runners + military - groin pain + positive Patrick's test \u2192 hospitalization and strict rest \u00b1 surgical fixation) + 5th metatarsal zone II (diaphyseo-metaphyseal junction - Jones fracture - runners + basketball - precarious vascular supply + risk of non-union \u2192 surgical fixation often recommended) + hallux sesamoids (dancers) + anterior femoral diaphysis (runners + military) + olecranon (throwers in extension) + patella ; location by discipline: runners: tibia + metatarsals + navicular + femoral neck; military: metatarsals + tibia + femoral neck + pelvis; dancers: metatarsals + sesamoids + tibia + L5 spondylolysis; gymnasts: L4-L5 spondylolysis + distal radius; rowers: ribs (6th-9th) + thoracic vertebrae<\/li>\n <li><strong>Clinical diagnosis and further examinations:<\/strong> clinical: progressive insidious pain on exertion + initially disappearing at rest (early stage) \u2192 pain persisting at rest (advanced stage) + exquisite pain point on direct bone palpation + tuning fork sign (vibrating tuning fork applied to bone - positive if pain worsens - sensitivity 75 %) + single-leg hop test (unipodal jump - reproducible pain); plain radiographs (2 incidences): often normal in the first 2-3 weeks (initial insensitivity: 15-35 %) - late appearance: cortical fracture line + periosteal reaction (bone callus) + trabecular condensation line - radiological normality does not exclude stress fracture; MRI (gold standard): reference technique - sensitivity 90-100 %, specificity 85-100 % - visible from 24-48h after onset of symptoms - sequences T1 (hyposignal) + STIR\/T2 fat-sat (medullary edema in hypersignal) + gadolinium if in doubt - Fredericson grading (grade 1 to 4) according to medullary edema and presence of fracture line - grade 3-4 = visible line = complete fracture; bone scan: alternative if MRI not available - high sensitivity but low specificity (does not distinguish stress fracture from periostitis or bone cancer) - useful for multifocal screening; CT: useful for complex stress fractures (navicular + sacrum + vertebrae) + consolidation assessment<\/li>\n <\/ul>\n\n <h2>Treatment and Return to Sport<\/h2>\n <table class=\"co-table\">\n <colgroup><col style=\"width:200px;\"><col style=\"width:42%;\"><col><\/colgroup>\n <thead>\n <tr><th>Treatment<\/th><th>Terms and Protocol<\/th><th>Duration, results, and precautions<\/th><\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Discharge and Rest \u2014 Low-Risk Fractures<br><small style=\"font-weight:400;color:#7a8fa0;\">Tibia, fibula, metatarsals 2\u20134, calcaneus<\/small><\/td>\n <td>Unloading and reduced weight-bearing are the mainstay of treatment for low-risk stress fractures - duration depends on anatomical site, MRI grade and clinical course;

post-surgical return-to-sport criteria (high-risk fractures): absence of pain + documented radiological consolidation (CT or Rx) + recovery of muscle strength (\u226590 % on contralateral side) + progressive resumption of impact according to protocol supervised by sports physician; close orthopedic follow-up: clinical + radiological check-up at 6 weeks + 3 months + 6 months after high-risk fractures - a BMD assessment (DXA) is recommended for all high-risk fractures and in sportswomen with RED-S factors.<\/td>\n <\/tr>\n <tr>\n <td>Nutritional and Bone Optimization<br><small style=\"font-weight:400;color:#7a8fa0;\">Calcium, vitamin D, RED-S assessment<\/small><\/td>\n <td>Optimizing nutritional and bone status is an integral part of stress fracture treatment - neglecting these factors exposes us to a high recurrence rate;

acute phase (unloading): non-impact strengthening of hip-stabilizing muscles (gluteals + abductors + external rotators - open-chain exercises : clamshells + lateral abduction + gluteal bridges + side-lying hip abduction) + trunk strengthening (sheathing) + off-load cardiovascular maintenance (swimming + cycling + aquajogging) + joint mobility maintenance (calf stretching + iliopsoas + hamstrings); recovery phase (progressive load): proprioception and unipodal balance + progressive closed-chain strengthening (unilateral squats + lunges + step-ups) + progressive plyometrics (jumping on two legs \u2192 one leg \u2192 rebounds) before resuming running; video analysis of running (running gait analysis): evaluation of running pattern (heel strike vs. midfoot strike) + cadence (target 170-180 steps\/min - 5-10 % reduction in impact forces) + vertical oscillation + trunk inclination angle + hip-to-ground control (dynamic Trendelenburg) - correction of running pattern reduces tibial impact forces by 20-30 %; orthopedic insoles and footwear: custom-made foot orthotics if hyperpronation or documented sunken foot + pronation control \u2192 reduced stress on tibia and metatarsals + running shoes adapted to foot and running pattern (sufficient cushioning + 8-12 mm drop for tibial fractures)<\/td>\n <td>Evidence for the efficacy of running retraining in stress fracture prevention: Crowell and Davis 2011 (Clinical Biomechanics) - reduction in vertical impacts by 20 % via feedback from cadence and foot strike - maintained at 1 month + 3-month follow-up;

Unlike a traumatic fracture caused by a single violent impact, a stress fracture occurs progressively: repeated microtrauma creates microcracks in cortical or trabecular bone tissue, which accumulate faster than the bone can repair them. Normal bone remodeling involves prior osteoclastic activation (resorption) followed by osteoblastic formation (deposition of new bone tissue) - when the rate of mechanical loading exceeds this repair cycle, the bone becomes progressively more fragile, leading to cracking or complete fracture. Stress fractures account for 1 to 20 % of sports injuries, depending on the discipline, with a particularly high incidence among long-distance runners, military personnel undergoing intensive training, gymnasts and dancers. The most frequent sites are the tibia (posteromedial part - 50 % of stress fractures), metatarsals (2nd and 3rd - 20 %), fibula, calcaneus, tarsal navicular and femoral neck. A distinction is made between low-risk stress fractures - located on the compression side of the bone, healing spontaneously with rest - and high-risk stress fractures - located on the tension side, exposed to complete displaced fracture with risk of non-union (navicular, femoral neck upper surface, sesamoids, anterior femoral diaphysis, 5th metatarsal base) - requiring urgent specialized orthopedic management. The female athlete's triad - relative energy deficit in sport (RED-S) + dysmenorrhea\/amenorrhea + osteoporosis - is a major risk factor for recurrent stress fractures in sportswomen.\n <\/div>\n\n <h2>Risk factors, location, and diagnosis<\/h2>\n <ul class=\"co-list\">\n <li><strong>Intrinsic and extrinsic risk factors:<\/strong> extrinsic (training-related) factors: rapid increase in training volume or intensity (10 % rule - do not increase weekly mileage by more than 10 % per week) + change of training surface (asphalt + concrete vs. grass + track) + unsuitable or worn-out footwear (>600-800 km) + hasty return to sport after injury or prolonged stoppage; intrinsic (patient-related) factors: low bone mineral density (BMD) - osteopenia + osteoporosis + malnutrition + low calcium and vitamin D intake + RED-S (Relative Energy Deficiency in Sport - formerly athlete's triad) + hypothalamic amenorrhea + eating disorders; biomechanical: lower-limb alignment disorders (genu varum + flat or hollow foot + hyperpronation + leg length discrepancy) + gluteal muscle weakness + calf stiffness + high-impact running pattern (heel strike); bone metabolism: hyperparathyroidism + malabsorption (celiac disease) + chronic hypovitaminosis D + corticosteroid treatment + history of stress fracture (risk \u00d7 2-4); hormonal factors: amenorrhea >3 cycles + hypoestrogenism (progestin-only contraceptive + post-menopause) + male hypogonadism (low testosterone - elite athletes + male RED-S)<\/li>\n <li><strong>Locations according to risk and sport discipline:<\/strong> low-risk fractures (face in compression - usual spontaneous healing under unloading and rest): posteromedial tibia (runners - 2nd most frequent site) + distal fibula (runners) + 2nd-4th metatarsals (runners + dancers) + calcaneus (military + runners) + ribs (rowers + golfers) + clavicle + humerus; high-risk fractures (face in tension - risk of complete fracture + non-union): tarsal navicular (sprint runners + basketball - pain dorsal face midfoot + N sign) + femoral neck superior face (long-distance runners + military - groin pain + positive Patrick's test \u2192 hospitalization and strict rest \u00b1 surgical fixation) + 5th metatarsal zone II (diaphyseo-metaphyseal junction - Jones fracture - runners + basketball - precarious vascular supply + risk of non-union \u2192 surgical fixation often recommended) + hallux sesamoids (dancers) + anterior femoral diaphysis (runners + military) + olecranon (throwers in extension) + patella ; location by discipline: runners: tibia + metatarsals + navicular + femoral neck; military: metatarsals + tibia + femoral neck + pelvis; dancers: metatarsals + sesamoids + tibia + L5 spondylolysis; gymnasts: L4-L5 spondylolysis + distal radius; rowers: ribs (6th-9th) + thoracic vertebrae<\/li>\n <li><strong>Clinical diagnosis and further examinations:<\/strong> clinical: progressive insidious pain on exertion + initially disappearing at rest (early stage) \u2192 pain persisting at rest (advanced stage) + exquisite pain point on direct bone palpation + tuning fork sign (vibrating tuning fork applied to bone - positive if pain worsens - sensitivity 75 %) + single-leg hop test (unipodal jump - reproducible pain);
