Epiphyseal traction to correct acquired growth deformities. An animal and clinical investigation.

In a canine model with a transepiphyseal distal femoral fracture, varus deformity was corrected and the arrested limb was lengthened using transphyseal traction (turnbuckle). Correction was possible without removing the transphyseal bone bridge operatively. Subsequent growth was not adversely affected in most animals. Based on this study, two patients with significant growth deformities secondary to an enchondroma were treated by epiphyseal traction. Although correction was achieved initially, both lost the length previously gained because of premature removal of the external fixator and/or subsequent early growth plate closure.
