Background

A literature review did not reveal any studies concerning the intramedullary transfer of the flexor digitorum brevis tendons (FDB) technique with a single longitudinal incision through the proximal phalanx of the toes. The main goal of this investigation was to demonstrate whether the FDB tendons of the toes are long enough to enable intramedullary transfer to the dorsal area of the proximal phalanx.

Methods

We examined whether the technique would allow the surgeon to transfer the FDB tendons through the proximal phalanx of the toes. The technique transfers the FDB tendons through the proximal phalanx dorsal area of the toes using an intramedullary transfer of the FDB tendons. The intramedullary transfer of the FDB tendons was performed through a single dorsal incision.

Results

The FDB tendons for the second, third, and fourth toes were performed in 100% of the feet. No ruptures in any toe in which the surgical technique was performed was noted, and no proximal phalanges of the second, third, and fourth toes were fractured.

Conclusions

Transfer of FDB tendons via the intramedullary approach of the proximal phalanx of the second, third, and fourth toes is possible. The FDB tendons have sufficient length for transfer via an intramedullary transfer and were carried out in 100% of the second toes. For a successful transfer, it is essential to perform a thorough resection of the extensor digitorum longus aponeurosis since it has expansions intimately attached to the plantar base of the proximal phalanx of the toe.

指趾短屈肌腱髓内转移矫正爪状趾/锤状趾畸形：横断面研究

背景

文献综述没有揭示任何关于通过脚趾近节指骨进行单一纵向切口进行的指短屈肌腱 (FDB) 髓内转移的研究。这项调查的主要目标是证明脚趾的 FDB 肌腱是否足够长，能够将髓内转移到近节指骨的背侧区域。

方法

我们检查了该技术是否允许外科医生通过脚趾的近节指骨转移 FDB 肌腱。该技术使用 FDB 肌腱的髓内转移，通过脚趾的近节指骨背侧区域转移 FDB 肌腱。FDB 肌腱的髓内转移是通过单个背侧切口进行的。

结果

第二、第三和第四脚趾的 FDB 肌腱在 100% 的脚上进行。没有注意到进行手术技术的任何脚趾的破裂，并且第二、第三和第四脚趾的近节指骨没有骨折。

结论

可以通过第二、第三和第四脚趾近节指骨的髓内入路转移 FDB 肌腱。FDB 肌腱具有足够的长度，可通过髓内转移进行转移，并在 100% 的第二脚趾中进行。为了成功转移，必须彻底切除趾长伸肌腱膜，因为它的扩张与脚趾近节指骨的足底紧密相连。
