The authors review 63 surgical cases of adolescent hallux abducto valgus in 54 patients from the Foot and Ankle Institute of the Pennsylvania College of Podiatric Medicine over a 7-year period. Twenty-five closing base wedge and capital osteotomies were evaluated for radiographic changes. Three quarters of a group of 65 patients with adolescent hallux abducto valgus were found to have an abnormally high metatarsus adductus angle. Patients who had a closing base wedge osteotomy had higher preoperative radiographic angles for the intermetatarsal, metatarsus adductus, hallux abductus, and proximal articular set angles as well as the tibial sesamoid position. Those patients had 4.49 degrees more intermetatarsal angle correction than the patients who had a capital osteotomy. Implications for evaluation and treatment are discussed.
作者回顾了宾夕法尼亚足病医学院足踝研究所54例患者的63例青少年拇外翻手术病例，时间跨度为7年。对25例闭合基底楔形截骨术和跖骨近端截骨术进行了影像学变化评估。在一组65例青少年拇外翻患者中，四分之三的患者被发现有异常高的跖骨内收角。接受闭合基底楔形截骨术的患者术前的跖骨间角、跖骨内收角、拇外翻角、近端关节固定角以及胫骨籽骨位置的影像学角度更高。这些患者的跖骨间角矫正比接受跖骨近端截骨术的患者多4.49度。文中讨论了评估和治疗的意义。
