A longitudinal outcome study of the tricorrectional bunionectomy with AO screw fixation for the correction of hallux abducto valgus was undertaken involving 84 consecutive patients (121 feet) with a mean age of 48.4 years who underwent the procedure over a 6-month period. Preoperative and postoperative measurements of forefoot angles were calculated, with the following mean results obtained: intermetatarsal angle of 14.46 degrees corrected to 5.72 degrees, hallux abductus angle of 26.38 degrees corrected to 11.65 degrees, proximal articular set angle of 19.85 degrees corrected to 6.06 degrees, and tibial sesamoid position of 4.75 corrected to 1.87. The average time to return to athletic shoes was 12.63 days. Postoperative complications were minor, with no delayed unions, malunions, hematomas, bone infections, or hallux varus. Long-term follow-up (mean, 21.33 months) using the American Orthopaedic Foot and Ankle Society's objective Hallux Metatarsophalangeal-Interphalangeal Scale revealed an overall mean score of 88.94 points out of a possible 100. An excellent mean result of 95 points out of a possible 100 on the subjective patient rating scale was also reported.
对采用AO螺钉固定的三矫正拇外翻切除术进行了一项纵向结果研究，该研究纳入了84例连续患者（121只脚），平均年龄48.4岁，这些患者在6个月内接受了该手术。计算了术前和术后前足角度的测量值，得到以下平均结果：跖间角从14.46度矫正至5.72度，拇外展角从26.38度矫正至11.65度，近端关节固定角从19.85度矫正至6.06度，胫侧籽骨位置从4.75矫正至1.87。恢复穿运动鞋的平均时间为12.63天。术后并发症轻微，无延迟愈合、畸形愈合、血肿、骨感染或拇内翻。使用美国矫形足踝协会的客观拇趾跖趾关节-趾间关节量表进行长期随访（平均21.33个月），在满分100分中总体平均得分为88.94分。在患者主观评分量表上，在满分100分中也报告了95分的优异平均结果。
