XXXX of the femoral shaft.

@entity1 @entity174 @entity158 @entity1642 @entity3330
For this study, all displaced @entity1642 of the femoral shaft treated during a 20-year period at a national military hospital were analyzed. Ten previously healthy male recruits sustained displaced @entity3330 , the incidence being 1.5 per 100,000 @entity1 -years in military service. The median age of the @entity1 was 19 years (range, 18-20 years). None had any previous @entity1642 . The median body mass index was normal. Before the @entity174 , nine recruits experienced thigh or knee @entity158 for 1 to 6 weeks. Six of the 10 @entity174 were located in the distal third of the diaphysis. Only one @entity174 occurred in the proximal third. Six @entity174 showed a noncomminuted, oblique, or oblique-transverse configuration. Five @entity174 were treated using an intramedullary nail, four @entity174 with a dynamic compression plate, and one with a dynamic condylar screw-plate. The bone at the site of @entity174 proved to be abnormally brittle. In six @entity1 this resulted in additional comminution intraoperatively. Two reoperations were necessary to exchange a nail and a screw because of technical faults. The median time to solid bony union was 3.5 months (range, 3-5 months). The recruits returned to light duty military service 6 weeks postoperatively, on the average. Two were exempted from military service for 2 years. Displacement is a rare, highly undesirable consequence of fatigue osteopathy of the femoral shaft among young recruits during basic military training. Preventive methods should focus on early, effective detection of developing @entity1642 to avoid a displaced @entity174 , with subsequent prolonged morbidity and possible complications. Gentle handling of the bone during the @entity174 fixation procedure is imperative because of the extraordinary brittleness of the @entity174 fragments.
