AbstractFemoral neck stress fractures (FNSFs) are increasingly common, particularly in military training. The usual mode of classifying these injuries is based on the involvement of the compression or tension side of the femoral neck; however, this may oversimplify and fail to address factors such as the orientation of the fracture line. We present a novel subtype of a compression-sided FNSF affecting the subcapital femoral neck and report the treatment outcomes in a military trainee population. A retrospective analysis of patients with a subcapital, compression-sided FNSF was identified from a single U.S. Army basic trainee installation. Radiographic evaluation as well as treatment outcomes associated with the ability to complete military training were reported. A total of three patients with a subcapital compression-sided FNSF were identified in a military trainee population, accounting for 10% of all FNSFs that developed over a 3-month period. Of these individuals, one was treated operatively while the other two were treated non-operatively. Overall, one patient was able to return to and successfully complete military training.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2022.
