Fixed flexion deformity of the proximal interphalangeal joint with or without hyperextension of the metatarsaophalangeal joint, hammertoe, is one of the most common foot deformities. Many surgical options have been recommended including the use of a more flexible PDS Orthosorb absorbable pin for fixation. The authors, using the PDS pin technique, reported some coronal angulations with painful soft corns requiring surgical correction. A new proximal interphalangeal joint arthrodesis procedure for hammer toe deformities utilizing a stiffer poly L-lactate 2-mm absorbable pin for internal fixation is presented.
Forty-seven toe procedures were done on 29 patients followed for an average of 18 (range, 10 to 36) months. Final evaluation included: physical exam, X-rays, MRI scan, AOFAS score, and a patient satisfaction survey.
Utilization of the stiffer poly-L-lactate absorbable pin resulted in minimal coronal angulations, no soft corns, high fusion rates and patient satisfaction.
The stiffer poly-L-lactate absorbable pin technique in this study was found to be superior to the published results using other methods of fixation including the more flexible PDS absorbable pin.
近节指间关节的固定屈曲畸形伴或不伴跖趾关节的过度伸展、槌状趾是最常见的足畸形之一。已经推荐了许多手术选择，包括使用更灵活的 PDS Orthosorb 可吸收钉进行固定。作者使用 PDS 钉技术报告了一些存在冠状面成角的病例，这些病例伴有疼痛性软鸡眼，需要手术矫正。本文提出了一种新的用于治疗槌状趾畸形的近节指间关节融合术，采用更硬的聚 L-乳酸 2mm 可吸收钉进行内固定。
对 29 例患者的 47 个脚趾手术进行了随访，平均随访 18 个月（范围 10-36 个月）。最终评估包括：体格检查、X 线片、MRI 扫描、AOFAS 评分和患者满意度调查。
使用更硬的聚 L-乳酸可吸收钉导致最小的冠状面成角、无软鸡眼、高融合率和患者满意度。
在这项研究中，与使用其他固定方法（包括更灵活的 PDS 可吸收钉）的结果相比，更硬的聚 L-乳酸可吸收钉技术被发现具有优势。
