Femoral-neck fractures in young adults.

Twenty-two young adult patients with femoral-neck fractures fitting the following criteria were evaluated. All patients (1) were between twenty and forty years old, (2) had clinical and follow-up roentgenograms at least twelve months after the injury, (3) incurred fracture of the neck of the femur through normal bone, and (4) did not incur a stress fracture. The incidence of non-union was 59 per cent (thirteen of twenty-two patients) and of avascular necrosis, 86 per cent (nineteen of twenty-two patients). Evaluation of patients and results are discussed.
