A simpler surgical technique to treat aseptic nonunion-associated femoral length discrepancy.
In a prospective study from December 1986 to August 1989, 17 consecutive patients with femoral shortening due to aseptic nonunion of femoral shaft fractures were treated with limitedly open Gross-Kempf locking nailing with a lengthening procedure. Patients were followed up for at least 1 year (average 25 months). There was a 88.2% union rate with an average union period of 5.2 months. Average lengthening was 2.4 cm (1.0 approximately 3.0 cm), and average operation time 90 min (70 approximately 130 min). The blood loss was slight (average 200 ml). Complications (11.8%) were 5.9% implant failure and 5.9% nonunion which were not difficult to manage. No neurovascular complications were noted. We conclude that for 5 cm shortening or less in femoral aseptic nonunion, this treatment constitutes the simplest technique and can achieve a very satisfactory result.
