Exercise-induced stress injuries to the femur

摘要: Seventy-one athletes with 74 stress injuries to the femur were studied using a case-controlled design. Forty-three females (26.6 yrs) and 28 males (31.2 yrs). Each patient had exercise-induced pain in hip, groin or thigh Tec-99m-MDP bone scan showing focal uptake of radionuclide femur. Running was most common activity at time injury (89.2%) followed by triathlon (4.6%) aerobic dance (4.6%). Thirty per cent runners increased their training duration immediately prior first symptom. Anterior frequent site (45.9%) hip (27%) (8.1%). During clinical examination, when asked hop on affected limb, 70.3% patients reproduced anterior thigh. There 39 cases (53%) involving femoral shaft, 15 (20%) lesser trochanter, 11 (15%) intertrochanteric region between neck greater 8 (11%) 1 (1%) trochanter. Two suffered displaced fractures, one other shaft Neither previously sought medical attention for leg pain. Of 46 plain radiographs taken, only (24%) abnormal. The mean diagnosis recovery 6.6 10.4 weeks respectively. Substitution cycling water exercise running therapeutic interventions.
