Three fractures of the femoral neck after intramedullary nailing for diaphy
seal fracture are reported. In two cases, the diagnosis was established aft
er nailing but the iatrogenic etiology may be not sure because of an imperf
ect primary radiological exploration. The localisation of the entry point a
nd the rigidity of Grosse-Kempf's nail could be a contributive factor of th
is exceptionnal complication.
