One-Stage Metatarsal Interposition Lengthening With an Autologous Fibula Graft for Treatment of Brachymetatarsia.

Brachymetatarsia is defined as the pathological shortening of a metatarsal bone, which can cause cosmetic problems and pain in the forefoot. The main surgical treatment options are: extension osteotomy, interposition of a bone graft, and callus distraction. Usually, a bone graft from the iliac crest is used for the interposition osteotomy.

Acetabular reconstruction in developmental hip dysplasia using reinforcement ring with a hook.

We followed prospectively 27 patients with severe acetabular bone-stock deficiencies due to developmental dysplasia of the hip. Mean preoperative patient age was 56 (34-78) years, mean Harris hip score was 31 (16-66) points and pre-operative mean acetabular angle of Sharp was 47 degrees (34 degrees - 61 degrees). Operative acetabular reconstruction was performed in 28 hips using reinforcement ring with a hook placed in the true acetabulum and autologous bone grafting.
