Fixed flexion deformity of the proximal interphalangeal joint with or without hyperextension of the metatarsophalangeal joint is one of the most common foot deformities. Many operative options have been recommended. Complaints after operative procedures include a too straight toe, floating toe, painful toe recurvatum, mallet toe, pin track infection, broken hardware, and the necessity of removing hardware. A proximal interphalangeal joint arthrodesis for hammertoe deformity using a 2-mm absorbable pin for internal fixation is described.
The results of 48 toe arthrodeses in 35 patients were reviewed. Followup ranged from 16 to 58 (average 38.5) months.
The procedure is simple and safe for the correction of painful rigid hammertoe deformities. Patient satisfaction was high, complications were minimal, and followup required no pin management or removal.
This procedure can be used for hammer toe deformities requiring surgery when the metatarsophalangeal joint is stable, the skin is not compromised, and the intramedullary canal of the proximal phalanx is 2.0 mm or less. It also has been useful in stabilizing hammertoe correction when there are severe pre-existing metal allergies.
近端指间关节固定性屈曲畸形伴或不伴跖趾关节过伸是最常见的足部畸形之一。已经推荐了许多手术选择。手术后的主诉包括脚趾过直、浮动趾、疼痛性趾背伸畸形、槌状趾、针道感染、内固定物断裂以及取出内固定物的必要性。本文描述了一种使用2毫米可吸收针进行内固定治疗槌状趾畸形的近端指间关节融合术。
回顾了35例患者48例趾关节融合术的结果。随访时间为16至58个月（平均38.5个月）。
该手术对于矫正疼痛性僵硬槌状趾畸形简单且安全。患者满意度高，并发症极少，随访时无需处理或取出钢针。
当跖趾关节稳定、皮肤未受损害且近端指骨髓腔为2.0毫米或更小，该手术可用于需要手术治疗的槌状趾畸形。当存在严重的既往金属过敏时，它在稳定槌状趾矫正方面也很有用。
