Limb reconstruction in Ollier's disease

We present our experience of lengthening and correction of complex deformities in the management of patients with Ollier's dysplasia (multiple enchondromatosis) from 1985 and 2002. All patients were under 18 years with a minimum follow-up time of 2 years (mean 9.6 years, range 2-15 years). There were a total of ten patients of which seven were male and three female. The mean age at presentation was 10.7 years (range 5-17 years; SD 3.7 years). The total length gain was 42.3 mm (range 30-110 mm; SD 28.9 mm). The number of days in external fixation was 164.8 days (range 76-244 days; SD 42.9 days). The bone healing index was 32.5 days/cm (18-50 days/cm; SD 10.3 days/cm). Patients with Ollier's disease have limb length inequality and angular deformities and require multiple reconstructive procedures owing to a high incidence of recurrence. We identified a tendency for the osteotomy to prematurely consolidate and advise the latency period after surgery to be 4-5 days and for distraction to proceed at a faster rate.
