Numerous procedures have been proposed through the years for the treatment of digital hammertoes and other related structural deformities. Experience has determined that many of these procedures are structurally incorrect and result in secondary deformity, which are often worse than the pathology initially addressed. Phalangeal base resections were found to destroy the structural stability provided by the intrinsic musculature. Phalangeal head resections make the toe impressionable to the extrinsic forces of the adjacent toes often leading to structural mal-alignment, or additional contracture. Similarly, indiscriminate tendon lengthenings have led to flail toes and a lack of purchase and propulsion. The advent of proximal interphalangeal joint arthrodesis demonstrated that structural stability and propulsion could be maintained while enhancing alignment. The "V" arthrodesis, as introduced by the authors, provides an alternative surgical approach to digital fusions. This approach is technically less difficult compared with a peg-in-hole fusion and provides enhanced stability when compared with an end-to-end arthrodesis. The preliminary results of this procedure appear to be most promising and are provided to the readership for review and examination.
多年来,人们提出了许多治疗趾锤状趾及其他相关结构畸形的手术方法。经验表明,其中许多手术方法在结构上是不正确的,并会导致继发性畸形,这些继发性畸形往往比最初要解决的病变更严重。人们发现,指骨基部切除术会破坏内在肌肉组织所提供的结构稳定性。指骨头切除术会使脚趾易受相邻脚趾外力的影响,常常导致结构排列不齐或额外的挛缩。同样,不加区分地进行肌腱延长术会导致连枷趾以及缺乏抓地力和推进力。近端指间关节融合术的出现表明,在改善对线的同时可以维持结构稳定性和推进力。作者介绍的“V”形融合术为手指融合提供了另一种手术方法。与 peg-in-hole 融合术相比,这种方法在技术上难度较小,与端对端融合术相比,稳定性更强。该手术的初步结果似乎非常有前景,现提供给读者以供审阅和研究。
