BACKGROUND
Vascular injury after hallux valgus surgery is a rare condition but serious complications can ensue.
METHODS
We performed an anatomical study using 26 cadaveric lower extremities. We enhanced first metatarsal bone's (FMB) vascularization by injecting latex. Each specimen was classified according to the severity of hallux valgus deformity (HVD). Then we measured two distances: one between the first tarsometatarsal joint (FTMJ) to the first dorsal branch's origin, the other between the first metatarsophalangeal joint (MTP) to the dorsal plexus's origin.
RESULTS
The distance between the FTMJ and the first dorsal branch to the FMB ranges from 10 mm in normal feet to 15 mm in severe deformed feet. The distance between the MTP and the dorsal plexus' origin ranges from 20 mm in normal feet to 25 mm in severe deformed feet.
CONCLUSIONS
Understanding the foot's vascular anatomy has allowed us to adapt surgical landmarks to the severity of the HVD and to avoid post-operative complications.
背景
踇外翻手术后的血管损伤是一种罕见的情况，但可能会引发严重的并发症。
方法
我们对 26 具尸体下肢进行了解剖学研究。通过注射乳胶增强第一跖骨（FMB）的血管化。根据踇外翻畸形（HVD）的严重程度对每个标本进行分类。然后我们测量了两个距离：一个是第一跖跗关节（FTMJ）到第一背支起源处的距离，另一个是第一跖趾关节（MTP）到背侧丛起源处的距离。
结果
FTMJ 与 FMB 第一背支之间的距离在正常足中为 10mm，在严重畸形足中为 15mm。MTP 与背侧丛起源处之间的距离在正常足中为 20mm，在严重畸形足中为 25mm。
结论
了解足部的血管解剖结构使我们能够根据 HVD 的严重程度调整手术标志，并避免术后并发症。
