Abstract

This article presents a clinical example of treatment of a patient with secondary post-traumatic deformity of the proximal femur due to a solitary bone cyst.

The cyst cavity was filled with spongeous bone homograft LYO-57, which served as a substrate for a consistent bone regeneration. The quality of the formed bone made it possible to perform corrective osteotomy of the proximal femur with stable osteosynthesis for the secondary deformity.

The results of treatment allow us to recommend this type of homotransplant for the treatment of patients with solitary bone cysts.
