Interlocking nailing for fractures of the femur and tibia.

In 132 patients, fractures of the lower limb (71 femoral and 61 tibial fractures) were treated using interlocking nailing (ILN) according to Grosse and Kempf during the period 1986-1989. Of these, 118 were followed up for a median of 19 months (range 9-32 months). Inpatient stay averaged 9 days regardless of the fracture. Consolidation was achieved in approximately 3 or 4 months from the operation in tibial and femoral fractures, respectively. Tibial fractures were technically more demanding than femoral ones, and their average operating time was significantly longer (73 min versus 51 min). Only one patient had a malunion in malrotation. The most serious complication was in a closed upper tibial fracture with traumatic rupture of the popliteal artery. Although the nailing was technically successful, an above-knee amputation had to be carried out. In only one case did the nail fail, and tibial plating had to be performed. Given the present degree of expertise, ILN for fractures of the long bones of the lower limb is a safe and relatively easy procedure to perform.
