Abstract
PURPOSE: Outcome assessment after double level tibial lengthening in patients with dwarfism. METHODS: Fourteen patients with dwarfism were analyzed after bilateral simultaneous double level tibial lengthening. RESULTS: Average age was 15.1 years. Average lengthening was 13.5 cm. The two levels were lengthened by an average of 7.5 cm proximally and 6.0 cm distally. Concomitant deformities were also addressed during lengthening. External fixation treatment time averaged 8.8 months. Healing index averaged 0.7 months/cm. CONCLUSION: Bilateral tibial lengthening for dwarfism is difficult, but the results are usually quite gratifying.
