Treatment of tibial hemimelia without amputation: preliminary report.

Treatment of tibial hemimelia, traditionally, is by amputation. This is not acceptable in our community. Hence we treated our cases without amputation. We treated two cases of type Ia and four cases of type II tibial hemimelia. The age at operation ranged from 3.5 to 13 years For type Ia cases, we applied the Ilizarov external fixator to the femur, fibula and foot to centralize the fibula between the femoral condyles and talus using gradual distraction. The second step was the Brown procedure. Then the fixator was reapplied to correct the deformities. For type II, synostosis of the tibia and fibula was performed followed by differential lengthening. Then we overlengthened the femur. After follow-up for 2-5.5 years, all patients showed improved function and were satisfied. The tibial lengthening ranged from 6 to 8.5 cm, and femoral lengthening ranged from 5 to 7 cm.
