      拇外翻畸形是指拇趾在第一跖趾关节处向外侧偏斜移位。拇囊炎是指在拇外翻畸形中出现的明显的内侧突起，但一般情况下这两个名词可互换使用。拇外翻是累及拇趾的最常见的病变，多见于中老年妇女，最常发生在有遗传倾向加上长时间穿不合适的鞋子的人，不合适的鞋子会对拇趾施加异常压力。拇外翻是一种复杂的解剖畸形，并且在治疗上极具挑战性。

Bunionectomy with Wedge Osteotomy

楔形截骨拇囊炎切除术

Overview（概述）

This outpatient procedure is performed to correct a bunion, a deformity of the toe joint. This surgery is commonly performed with regional anesthesia.

　　本门诊手术用于矫正拇外翻，一种脚趾关节的畸形。本手术常在区域麻醉下进行。

Bunionectomy（拇囊炎切除）

In preparation for the procedure, the patient is positioned and anesthesia is administered. The surgeon creates an incision along the side of the toe to expose the bunion. Typically, the surgeon will trim away the bony bump. If a tendon is pulling the toe out of alignment, the surgeon may release it. In some cases, these modifications may be enough to correct the deformity. But in severe cases the bones of the toe require realignment.

　　准备手术时，将病人摆放合适体位并施行麻醉。外科医生沿脚趾的侧面作一切口，以显露拇囊炎。通常，外科医生会修剪骨赘。如果因肌腱牵拉使脚趾失去正常序列，外科医生会松解肌腱。在有些病例，这样修整就足以矫正畸形。但是在严重病例，脚趾骨头的序列需要重新排列。

Osteotomy（截骨术）

To correct the toe's alignment, the surgeon carefully removes a wedge of bone and then shifts the head of the first metatarsal to improve the alignment. The head of this bone is stabilized with screws, pins or other fixation devices.

　　为矫正脚趾的序列，外科医生小心地去除一块楔形的骨头，然后将第一跖骨头转动以改善序列，并用螺钉、钢针或其它内固定装置固定跖骨头。

End of Procedure and Aftercare（手术结束和术后护理）

When the procedure is complete, the surgeon closes the incision and bandages the foot. After a brief period of monitoring, the patient is allowed to go home. The patient will wear a walking cast, splint or surgical shoe for the next several weeks while the toe heals. The patient will be able to resume normal activities after six to eight weeks.

　　手术完成后，外科医生将切口关闭并用绷带包扎患足。在短暂的监护后，病人被允许回家。在接下去数周内，随着脚趾的愈合，病人需要穿行走石膏、夹板或外科鞋地。大约6～8周后病人可恢复正常的活动。
