We aimed to compare the clinical and radiographic outcomes of minimally invasive surgery (MIS) and distal chevron metatarsal osteotomy (DCMO) for young female patients with mild-to-moderate juvenile hallux valgus deformity.
We retrospectively reviewed the radiographs and clinical findings of young female patients with mild-to-moderate juvenile hallux valgus who underwent MIS (25 feet) or DCMO (30 feet). In 12 of 25 MIS feet, 2.0-mm bio-absorbable pins were used as an additional fixation device crossing the osteotomy site, and 1.4-mm Kirschner wires were used in the remaining 13 feet.
Radiographic and clinical parameters preoperatively and at the final follow-up were not significantly different between the 2 groups. There were no significant differences in the increments of hallux valgus angle (HVA), distal metatarsal articular angle, medial sesamoid position, first metatarsal length, metatarsal length index, or relative second metatarsal length. Two MIS subgroups according to the additional fixation device showed no significant differences in HVA, the first to second intermetatarsal angle lateral translation ratio, or plantar offset at the final follow-up.
MIS for young female patients with mild-to-moderate juvenile hallux valgus deformity had similar radiographic and clinical outcomes compared to DCMO. Regarding additional fixation crossing the osteotomy site, both temporary Kirschner wires and absorbable pins showed no radiographic differences in terms of correction maintenance.
我们旨在比较微创手术（MIS）和远端V形截骨术（DCMO）治疗轻至中度青少年拇外翻畸形年轻女性患者的临床和影像学结果。
我们回顾性分析了接受MIS（25足）或DCMO（30足）治疗的轻至中度青少年拇外翻年轻女性患者的X线片和临床资料。在25例接受MIS治疗的足中，12足使用2.0毫米生物可吸收钢针作为穿过截骨部位的额外固定装置，其余13足使用1.4毫米克氏针。
两组术前和末次随访时的影像学和临床参数无显著差异。拇外翻角（HVA）、第一跖骨远端关节角、内侧籽骨位置、第一跖骨长度、跖骨长度指数或相对第二跖骨长度的增加无显著差异。根据额外固定装置划分的两个MIS亚组在末次随访时的HVA、第一和第二跖骨间角外侧平移率或跖侧偏移方面无显著差异。
对于轻至中度青少年拇外翻畸形的年轻女性患者，MIS与DCMO的影像学和临床结果相似。关于穿过截骨部位的额外固定，临时克氏针和可吸收钢针在矫正维持方面的影像学表现无差异。
