Fibular-Lengthening Osteotomy in Patient with Progressive Valgus Deformity After an Ankle Fracture.

BACKGROUND The fibular fracture requires an anatomical reduction. When a malunion occurs, it can lead to a valgus deformity with an opening of the ankle mortise. CASE REPORT This case deals with a 23-year-old patient with pain and limited movement in the right ankle, caused by a fracture healed in an incorrect position, with shortening of the fibula and progressive displacement of the valgus, after surgery 12 months earlier for an ankle fracture.

Extensor Mechanism Allograft in Osteosarcoma of the Patella: A Case Report.

Case: A 24-year-old female diagnosed with fibroblastic osteosarcoma of the patella underwent a total patellectomy and surgical reconstruction with a large bone-tendon allograft of the extensor mechanism and adjuvant chemotherapy. At 5 years' postoperative, the patient has adequate disease control and excellent joint function.

Conclusions: Reconstruction with an extensor mechanism allograft is an appropriate alternative for patients with malignant patella tumors without tumor contamination of the joint, allowing for satisfactory knee function and disease control.
