Abstract:
Objective: To evaluate the clinical effect of Z-shaped rotating osteotomy of metatarsal diaphysis in patients with moderate and severe hallux valgus with metatarsophalangeal joint incongruency. Methods: We selected 36 patients (38 feet) with moderate and severe hallux valgus with metatarsophalangeal joint incongruency who underwent Z-shaped rotating osteotomy of metatarsal diaphysis in the First Affiliated Hospital of Army Medical University of Chinese PLA from September 2010 to January 2019. There were 2 males and 34 females with an average age of (49±18) years (18-77 years). Hallux valgus angle (HVA), first-second intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), congruency index, length of first metatarsal, and functional scores were evaluated before and 6 weeks after surgery and at the last follow-up. The data were compared by one-way ANONA or t test. Results: The congruency index was significantly improved from 0.75±0.11 before surgery to 0.95±0.07 at the last follow-up (t=11.728, P<0.01). HVA and IMA improved significantly at 6 weeks after surgery, however, HVA at the last follow-up showed an increased trend compared with that at 6 weeks after the operation, while no significant improvement in IMA. Although DMAA increased slightly 6 weeks after surgery when compared with that before surgery, there was no significant difference in it between the last follow-up and the 6 weeks after surgery, and no significant difference in the length of the first metatarsal at different time points (F=0.991, P>0.05). In terms of functional scores, American Orthopaedic Foot & Ankle Society (AOFAS) score increased from 50±9 before surgery to 80±17 at the last follow-up, while visual analogue scale (VAS) decreased from 5.8±1.1 to 2.7±1.5, Manchester-Oxford Foot Questionnaire (MOXFQ) score decreased from 70±13 to 25±19 (t=12.024, 13.439, 16.880, all P<0.05). Conclusions: The treatment of moderate and severe hallux valgus with metatarsophalangeal joint incongruency by Z-shaped rotating osteotomy of metatarsal diaphysis can significantly increase the congruency index of metatarsophalangeal joint and improve the metatarsophalangeal joint matching relations. It will not significantly increase the DMAA. A certain degree of radiographic recurrence occurs during a longtime follow-up, but it doesn't influence the symptoms and function. 目的： 评估跖骨干"Z"字旋转截骨治疗伴有跖趾关节不匹配的中重度拇外翻患者的临床疗效。 方法： 选择2010年9月至2019年1月于陆军军医大学第一附属医院骨科行跖骨干"Z"字旋转截骨治疗的伴有跖趾关节不匹配的中重度拇外翻患者36例（38足)，其中男2例，女34例，年龄18~77（49±18）岁。评估患者术前、术后6周以及末次随访时的拇外翻角（HVA)、第一、二跖骨间角（IMA)、跖骨远端关节固定角（DMAA)、嵌合指数、第一跖骨长度以及功能评分情况。行单因素方差分析或t检验手术前后数据进行分析比较。 结果： 嵌合指数得到明显改善，由术前的0.75±0.11提升到了末次随访时的0.95±0.07(t=11.728，P<0.01)。术后6周HVA、IMA较术前有显著改善，末次随访的HVA较术后6周有增大的趋势，IMA并无明显差异，尽管术后6周DMAA较术前有轻微增大，但末次随访与术后6周差异并无统计学意义（P>0.05)，不同时间点的第一跖骨长度差异无统计学意义（F=0.991，P>0.05)。拇趾跖趾-趾间关节量表（AOFAS）从术前的（50±9）分提高到了术后末次随访的（80±17）分，疼痛视觉模拟评分（VAS）从术前的（5.8±1.1）分降至（2.7±1.5）分，曼彻斯特-牛津足部问卷（MOXFQ）从术前的（70±13）分降至末次随访的（25±19）分，差异均有统计学意义（t=12.024、13.439、16.880，均P<0.05)。 结论： 跖骨干"Z"字旋转截骨治疗伴有跖趾关节不匹配的中重度拇外翻能够明显提高跖趾关节嵌合指数，改善跖趾关节匹配关系，并且不会显著增大DMAA，尽管长时间的随访观察仍存在一定程度的影像学复发，但并未明显影响其症状及功能。.
