Opening wedge proximal metatarsal osteotomy combined with first metatarsophalangeal arthroplasty can be used to correct first metatarsus primus varus with a high intermetatarsal angle and a short first metatarsal.
147 feet in 138 patients with degenerative first metatarsophalangeal arthrosis, >or=15 degrees of metatarsus primus varus and, a short first metatarsal were included. Preoperative and postoperative clinical, radiographic, and subjective outcome measurements were taken (Scale AOFAS).
The mean first intermetatarsal angle decrease was 7.79+/-1.43 degrees and the mean increase in first metatarsal length was 2.88+/-0.45 mm. The pre-intervention mean values were 52.6 points in the AOFAS scale, and an overall result of 92.95 obtained after surgery (P<0.001).
The opening proximal first metatarsal osteotomy without internal fixation and with first metatarsophalangeal resection arthroplasty can correct severe hallux valgus with an intermetatarsal angle >or=15 degrees and a short first metatarsal, achieving low rate of complications.
撑开楔形近节跖骨截骨术联合第一跖趾关节成形术可用于矫正高跖间角和短跖骨的第一跖骨内翻。
纳入了 138 例 147 足患有退行性第一跖趾关节炎、>或=15 度的跖骨内翻和短跖骨的患者。进行了术前和术后的临床、影像学和主观结果测量（AOFAS 量表）。
第一跖骨间角平均减少 7.79+/-1.43 度，第一跖骨长度平均增加 2.88+/-0.45 毫米。术前 AOFAS 量表的平均分值为 52.6 分，术后总体评分为 92.95 分（P<0.001）。
不固定的撑开近端第一跖骨截骨术联合第一跖趾关节切除成形术可矫正跖间角>或=15 度和短跖骨的严重足拇趾外翻，并发症发生率低。
