Bilateral double level tibial lengthening in dwarfism

PurposeOutcome assessment after double level tibial lengthening in patients with dwarfism.MethodsFourteen patients with dwarfism were analyzed after bilateral simultaneous double level tibial lengthening.ResultsAverage 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.ConclusionBilateral tibial lengthening for dwarfism is difficult, but the results are usually quite gratifying.
