Simultaneous fractures of both femoral necks: review of the literature and report of two cases.

Simultaneous fracture of both femoral necks is extremely rare. Delay in diagnosis may be avoided by noting the association of these fractures with two conditions: violent skeletal trauma and major motor seizures. Treatment of two patients is reported in addition to a review of seven cases previously reported. The author's experience indicates that accurate reduction and percutaneous Knowles pinning provide adequate fixation and permit early weight-bearing.
