Femoral allograft in the management of osseous hydatidosis presenting as femoral shaft non-union.

Osseous hydatidosis is a rare infection posing diagnostic and therapeutic challenge. We present a case of extensive hydatidosis of the femoral shaft with non-union of pathologic fracture. Patient had resection of involved femur and post-operative chemotherapy. Subsequently femur reconstruction was done using a femoral allograft. At 26 months patient has no recurrence and bony union is seen at host-allograft interface. We present this technique as an extended indication of allograft used in limb reconstruction.
