Abstract

Background:

Young patients with a acquired dislocation of the hip with concomitant shortening of the lower limb is a difficult diagnostic problem with few definite treatment options.

Methods:

We used the technique, originally described by Ilizarov, with a double femur osteotomy and lengthening the femur. Lengthening was done with a sub muscular placed on-lay femur distraction rod. Distraction of the rod was done by fluid mechanics. After lengthening, the distraction was secured by a parked plate by locking the distal part of the plate.

Results:

This patient needed a lengthening of 60 mm, distraction time was 36 days with a distraction index of 1.61 mm per day and a healing index of 31.4 days per cm lengthening.We encountered one complication in which an exchange of the plastic feeding tube was needed at 20 days post-surgery.

Conclusions:

In the reported case we could improve gait with reduced limping and equalizing her leg length discrepancy.
