INTRODUCTION
A percutaneous selective flexor digitorum brevis (FDB) tenotomy and a proximal interphalangeal (PIP) joint arthrolysis may correct a lesser claw toe deformity keeping flexor digitorum longus (FDL) and active flexion. Our study aimed to verify if the procedure was effective and reliable and if it respects the surrounding soft tissues.
MATERIAL AND METHOD
Twelve cadaveric lateral toes were used. A dissection ensured the integrity of both digital nerves, FDL and flexor pulleys and assessed the section of both FDB slips and PIP arthrolysis.
RESULTS
A complete section of the two FDB slips was observed in 4 cases (33%). Arthrolysis was achieved in all cases. Surrounding soft tissues were found intact in all cases.
CONCLUSION
This procedure is effective regarding PIP arthrolysis, but a technical improvement is required to achieve a reliable section of both FDB slips. In the hands of an experienced surgeon, it has proven to be safe.
引言
经皮选择性趾短屈肌（FDB）腱切断术和近端指间关节（PIP）松解术可矫正轻度爪形趾畸形，同时保留趾长屈肌（FDL）及主动屈曲功能。我们的研究旨在验证该手术是否有效且可靠，以及是否会损伤周围软组织。
材料与方法
使用12个尸体侧趾。解剖过程中确保两条指神经、FDL和屈肌滑车的完整性，并评估FDB两条肌腱的切断情况及PIP关节松解情况。
结果
4例（33%）观察到FDB两条肌腱完全切断。所有病例均实现关节松解。所有病例中周围软组织均保持完整。
结论
该手术对于PIP关节松解有效，但需要技术改进以实现FDB两条肌腱的可靠切断。在经验丰富的外科医生手中，该手术已被证明是安全的。
