蜂鷹(Pernis Ptilorhynchus)右膝關節脫臼之復位手術

一隻亞成年蜂鷹(Pernis Ptilorhynchus)被送至特有生物研究保育中心野生動物急救站醫治，病鳥呈現蹲伏狀、不願站立、右跗蹠骨遠端皮膚環狀挫傷、右腿無力、鬆弛且向外側伸展角度過大。以放射線影像檢查顯示膝關節脫臼，右脛跗骨向內側脫出約1.5cm。病鳥以isoflurane氣體麻醉後將脛跗骨復位於膝關節內，分別於股骨遠端與脛跗骨近端處以順行性方式各打入1根骨髓內釘，將突出關節部之骨髓內釘折彎剪短，使用塑鋼土球黏合固定。病鳥於術後20日拆卸骨釘，隔日即可使用患肢站立抓握。術後38日已可飛到高處棲架上正常行走與跳躍。此復位手術可穩定地固定關節，適用於100g至1kg左右的鳥類，且不分年齡，手術操作簡單省時、不傷害膝關節且預後良好，可廣泛應用於野生鳥類、寵物鳥或觀賞鳥等。

An injured subadult oriental honey buzzard (Pernis ptilorhynchus) was admitted to the Wildlife First Aid Station at Endemic Species Research Institute. The bird presented ring-like skin bruising in the right distal tibiotarsus, hypertension of the right leg, and unwilling to stand. Examination by X-ray revealed a luxation of its right femorotibial joint, its right tibiotarsus and articular cavity was 1.5 cm apart. The bird was anesthetized by isoflurane and then reduced luxation. Intramedullary pins were normograded into the femur and tibiotarsus from the knee. The exposed portions of each pin were shorten and bent. These pins were joined with epoxy putty and the right leg was bandaged to provide rigid stability. Intramedullary pins were removed on the 20th day after surgery. The bird showed normally perching and jumping behaviors on the 21th and 38th day after surgery, respectively. This surgical technique represented a convenient and useful way to reduce femorotibial luxation in a wide variety of avian species.
