摘要

背景:研究表明,第一跖骨导致拇外翻。近节指骨是定义拇外翻角的另一个因素,也有助于拇外翻的发展。目前还没有使用计算机断层扫描来评估近节指骨的骨形态的报告。本研究的目的是利用计算机断层扫描分析近节指骨的形态和畸形及其与拇外翻的关系,并考虑拇外翻近节指指骨手术的适应证。方法:在2019年5月至2022年3月期间,在我们诊所咨询足部和踝关节疾病并接受了负重放射照相术和计算机断层扫描的患者被纳入研究。测量拇外翻角、籽骨半脱位、第一跖骨长度、近节指骨长度、跖骨-近节指节比、近节趾骨外翻角、跖骨近节趾角、近节趾旋转角和远节趾骨-近趾骨角。将这些参数在拇外翻组和对照组之间进行比较。在拇外翻组中,测量拇外翻角和近节指骨外翻角,并使用负重X线片进行比较。结果:65例患者中有83只脚被诊断为拇外翻(拇外翻组,平均年龄68.0±13.8岁),22例无拇外翻患者中有30只脚被纳入研究(对照组,平均岁67.0±25.8岁)。拇外翻组的近节指骨长度、跖骨-近节指指骨比例和角度以及远节指骨-近指骨角度均显著大于对照组。然而,近节指骨外翻和旋转角度在两组之间没有显著差异。结论:拇外翻组和对照组除长度外,近节指骨形态无显著差异,应仔细考虑近节指节骨截骨的适应证。

Morphology and deformity of the distal phalanx in hallux valgus

Background

Studies have shown that the first metatarsal contributes to hallux valgus. The proximal phalanx, another factor that defines the hallux valgus angle, also contributes to the development of hallux valgus. There have been no reports on the use of computed tomography to evaluate bone morphology of the proximal phalanx. The purpose of this study was to analyze the morphology and deformity of the proximal phalanx and its relationship to hallux valgus using computed tomography, and to consider the indications for proximal phalanx surgery in hallux valgus.

Methods

Patients who consulted at our clinic for foot and ankle disorders and underwent both weight-bearing radiography and computed tomography between May 2019 and March 2022 were included in the study. The hallux valgus angle, sesamoid subluxation, first metatarsal length, proximal phalanx length, metatarsal-proximal phalanx ratio, proximal phalanx valgus angle, metatarsal-proximal phalanx angle, proximal phalanx rotation angle, and distal phalanx-proximal phalanx angle were measured. These parameters were compared between the hallux valgus and control groups. In the hallux valgus group, the hallux valgus and proximal phalanx valgus angles were measured and compared using weight-bearing radiographs.

Results

A total of 83 feet in 65 patients were diagnosed with hallux valgus (hallux valgus group; mean age of 68.0 ± 13.8 years) and 30 feet in 22 patients without hallux valgus (control group; mean age of 67.0 ± 25.8 years) were included in the study. The proximal phalanx length, metatarsal-proximal phalanx ratio and angle, and distal phalanx-proximal phalanx angle were significantly greater in the hallux valgus group than in the control group. However, the proximal phalanx valgus and rotation angles were not significantly different between the groups.

Conclusion

Since there was no significant difference in the proximal phalanx morphology, except length, between the hallux valgus and control groups, the indications for osteotomy of the proximal phalanx should be carefully considered.
