患儿10岁，胫骨中上段慢性骨髓炎。一般情况好，体温不高，局部有流脓窦道，X线片有4cm长整段死骨，周围有不连续包壳。当前的主要治疗是（）。

A.手术摘除死骨，肌瓣填塞消灭死腔

B.手术摘除死骨，填入庆大霉素链，3周后取出，松质骨植入

C.手术摘除死骨，植入细塑料管，每日经管滴入抗生素

D.患肢长腿石膏管型固定，开窗换药

E.局部换药，保持引流通畅

答案

参考答案：D

解析：慢性骨髓炎有整段死骨，周围包壳不连续，其本身即有发生病理骨折可能。如此时摘除死骨，骨膜将失去内衬而塌陷，新骨形成将受到很大影响，甚至造成骨缺损。故正确的处理是给予外固定长腿石膏管型，开窗定期换药，待包壳充分形成后，再手术摘除死骨。
