Résumé
The present day fast and competitive life affects the sports and military training alike. The sense of competition and the desire to achieve the required standard during training makes it necessary to tolerate physical stress after getting fatigued. The muscle can not take the load after getting fatigued and load tolerated above muscle threshold will result in stress fracture. In this study a group of 141 male gentleman cadets/recruits with lower extremity pain and functional disorders were evaluated. The radionuclide bone seintigraphy and X ray studies were carried out to determine the incidence, and prognosis of stress fractures. It is concluded that the incidence of Stress fracture is higher among gentleman cadets, the commonest single bone involved is right tibia followed by left. Tibia and fibula. Drill exercise resulted the highest incident and the cemented and metalled ground were the main contributing factors to the stress fractures. Lack of exercise before coming to training centre is an additional important contributing factor. The plain radiograph are of little use in establishing the diagnosis in the early stage of injury while the investigation of choice is the radionuclide bone scan
