[First experience with correction of limb-length inequality and angular and rotational deformities of the tibia using the Taylor spatial frame]

Abstract

The authors analyse the first results of correction surgery for limb-length inequality and rotational and angular deformities of the tibia using the Taylor spatial frame in combination with the Ilizarov external fixator in three patients. The shortening of the tibia, 65 mm on the average (55, 60 and 80 mm, respectively), was due to tibial hemimilia in two patients and traumatic epiphyseolysis of the distal tibia in one patient. Distraction at a rate of 1 mm/day was controlled three-times a day on two contralateral struts. It started on the seventh day after osteotomy in all three patients. On the second post-operative day, rehabilitation started with standing up and walking with crutches. The additional fixation of the heel and foot was removed at 3 months after distraction was terminated so that ankle exercise would be possible. No serious complications were recorded. The average distraction index was 0.91 and the average tibial lengthening was 65 mm. Callus consolidation was achieved at 131 days after the end of distraction phase. Approximately at 10 months post-operatively, the patients reported full weight-bearing of the extremity.
