足三关节融合术是指跟距、跟骰、距舟3个关节的融合手术。术后踝关节仍保持有活动度。手术目的是稳定足部关节，矫正畸形，并恢复其功能。由于这3个关节面位于两个互相垂直的平面上，采用不同的楔形切除，可以矫正足的跖屈、仰趾、内翻、外翻、内收、外展或高弓畸形；两个平面的联合楔形切除，就可以对上述的各种联合畸形作三维矫正。足的畸形种种不同，程度不一，因此，三关节的切骨程度、固定方法也各不有同。术前应充分研究，对不同的畸形作出不同的设计；术中还应根据发现的情况，随时调整，才能收到满意效果。
Overview（概述）
This surgical procedure is used to help relieve pain in the ankle joint and correct deformities in the hindfoot caused by injury, arthritis, or genetic defect. The procedure fuses the three main joints in the hindfoot that allow side-to-side movement - the calcaneo-cuboid, talonavicular, and subtalar joints.
三关节融合术用于缓解踝关节疼痛和矫正因外伤、关节炎或先天性缺陷导致的后足畸形。本术式将后足的三个主要关节（跟骰、距舟、距下关节，可进行侧向运动）融合在一起。
Preparation（准备）
The patient is positioned so that all sides of the foot are clearly visible to the surgeon. Anesthetic is administered and the area is cleaned and sterilized.
患者安置妥善，从而外科医生可以清楚地观察足的每一侧。麻醉后术区清洁消毒。
Accessing the Ankle Joint （显露关节）
An incision is made on the outside of the foot, just below the ankle. A second incision is made on the inside of the ankle. The joints are examined and all remaining cartilage between the bones of these joints is removed. If the hindfoot is misaligned, its position is corrected.
在足外侧刚好踝关节下方作一切口，然后在踝关节内侧作第二个切口。检查关节，将这些关节骨间的残余软骨去除。如果后足排列异常，矫正其位置。
Fusing the Joint（融合关节）
Screws, staples, or plates are inserted to stabilize the bones of the joint. Bone graft is packed around the space between the bones if needed. Over time, these bones will fuse together.
用螺钉、矩形钉或钢板将关节的骨头固定。如有必要，在骨头之间的空隙内植入骨移植物。经过一段时间，这些骨头会融合到一起。
End of Procedure and After Care（手术结束和术后护理）
The incision is closed with sutures or surgical staples. The ankle may be placed in a brace or half-cast, and a short hospital stay will be required. Weight should not be applied to the foot for at least six weeks after the surgery. A walking cast may then be used for at least another six weeks. Full recovery usually takes up to ten months.
缝合或用皮钉关闭切口。用支具或石膏托固定踝关节。需要短期住院。术后患足不能负重至少6周。此后使用行走石膏至少6周。完全康复通常需要10个月。
