Use of Ender's nails in unstable trochanteric femoral fractures.

Eighty consecutive patients with unstable trochanteric femoral fractures treated by the Ender technique have been studied. Early fixation failure was seen in 18% of patients. Leg shortening and external rotation deformities due to uncontrolled fragmentary collapse were found in almost 80% of the 57 surviving patients at 3 months, and caused severe disability. The continued use of the Ender technique in unstable fractures is questioned.
