Hallux valgus is a progressive angular deformity of the big toe, the degree of which is aggravated in weightbearing stance. Hallux valgus and intermetatarsal angles on postoperative weightbearing images are usually larger than those of intraoperative fluoroscopic and immediate postoperative non-weightbearing images. Here, we hypothesized that various angular parameters of hallux valgus would increase postoperatively with weightbearing. A total of 66 feet (58 patients) of moderate to severe hallux valgus were reviewed on consecutive plain foot anteroposterior radiographs. The changes of hallux valgus, intermetatarsal, hallux valgus interphalangeal, and distal metatarsal articular angles were compared. Hallux valgus and intermetatarsal angles were significantly increased with weightbearing postoperatively (p < .001). Hallux valgus interphalangeal and distal metatarsal articular angles did not show significant changes with weightbearing (p > .5). Hallux valgus and intermetatarsal angles were increased with weightbearing after hallux valgus surgery. Mean angular changes were 5.3 and 2.7 degrees, respectively. These values should be considered in the preoperative planning and intraoperative correction processes.
拇外翻是大脚趾的一种进行性角畸形，其程度在负重站立时会加重。术后负重图像上的拇外翻和跖间角通常比术中透视和术后即刻非负重图像上的更大。在此，我们假设拇外翻的各种角参数在术后负重时会增加。我们对连续的足部前后位平片上的66只脚（58例患者）的中重度拇外翻进行了回顾。比较了拇外翻、跖间、拇外翻指间和远端跖骨关节角的变化。术后负重时拇外翻和跖间角显著增加（p <.001）。拇外翻指间和远端跖骨关节角在负重时未显示出显著变化（p >.5）。拇外翻手术后，拇外翻和跖间角随负重增加。平均角变化分别为5.3度和2.7度。在术前规划和术中矫正过程中应考虑这些值。
