Stress fractures of the hip in Royal Marine recruits under training: a retrospective analysis

At the Commando Training Centre, Royal Marines (CTCRM), a retrospective analysis of the occurrence of one form of stress fracture--that of the hip--has shown that this fracture is a significant cause of morbidity in the recruits. Most fractures presented in the last few weeks of training, which may reflect the increasing workload that the training involves. Two different fracture sites are identified, but there is no discernible difference in presentation or outcome between them. The condition may be easily misdiagnosed as a more trivial injury. A careful history and examination, and a low threshold for radiographic and scintigraphic investigation are important for diagnosis, and to avoid the catastrophic failure of the fracture seen in one of our patients.
