Limb lengthening using ankle joint distraction (arthrodiastasis) followed by arthrodesis. Experience with one case.

Tibial aplasias are difficult entities to manage and sometimes require significant limb lengthening. Preserving the joint is the preferred option in these cases. However, when function is not ensured, lengthening beginning in the joint can be attempted followed by arthrodesis. This report presents the clinical and radiological results of a patient treated with intra-articular lengthening (or arthrodiastasis) associated with talocrural arthrodesis. Although this original technique provided satisfactory results, this surgical program remains complicated.
