Intramedullary nailing of femoral fractures in adolescents

Fifty femoral shaft fractures were treated with reamed, interlocking, intramedullary nails utilizing a greater trochanteric starting point from 1991 through 1998. The 17 girls and 31 boys ranged in age from 10 to 16 years (mean, 13.2 years) at the time of injury. Average follow-up after fracture was 16 months. All fractures united, and the average leg-length discrepancy was 1 mm (range, -10 mm to +11 mm). No patient had angular or rotational deformities. No patients developed osseous necrosis of the femoral head. Despite intramedullary nailing through the greater trochanteric apophysis, articulotrochanteric distance measurements increased only 4.5 mm at the time of last follow-up. No patient developed significant proximal femoral deformity with some follow-up as far as 60 months from the time of surgery. Intramedullary nailing through a trochanteric starting point is a safe, effective method for treating femur fractures in this adolescent age group.
