To investigate the changes of plantar pressure distribution in patients who underwent either Austin or Scarf osteotomy and underwent a postoperative rehabilitation program.
Between September 2006 and December 2007, 50 participants who suffered from mild to moderate hallux valgus deformity were prospectively included in this study. An Austin osteotomy (Austin group) was performed in 25 patients and a Scarf osteotomy (Scarf group) in 25 patients. Indication for the Scarf or Austin technique was made according to the consensus of the Austrian society of foot and ankle surgery. Plantar pressure analysis was performed at 4 weeks, 8 weeks, and 6 months postoperatively. Furthermore, range of motion and the American Orthopaedic Foot and Ankle Society (AOFAS) questionnaire were evaluated.
In the big toe and first metatarsal head region in groups, maximum force, peak pressure, and force-time integral increased significantly from 4 weeks to 6 months postoperatively (P ≤ 0.001). The mean AOFAS score increased from 60.7 preoperatively to 93.1 6 months after Austin surgery and from 56.7 preoperatively to 94.4 6 months after Scarf surgery. The Austin group had a mean range of motion (ROM) of 68.5° that increased to a mean ROM of 75.5° 6 months postoperatively, while the Scarf group had a mean ROM of 67.8° that increased to a mean ROM of 68.2° 6 months postoperatively.
Despite different surgical techniques and the degree of deformity, there were no differences in plantar pressure parameters and functional outcomes between both groups.
研究接受奥斯汀截骨术或斯卡夫截骨术并进行术后康复计划的患者足底压力分布的变化。
2006年9月至2007年12月，前瞻性纳入50例轻至中度拇外翻畸形患者。25例患者接受奥斯汀截骨术（奥斯汀组），25例患者接受斯卡夫截骨术（斯卡夫组）。根据奥地利足踝外科学会的共识选择斯卡夫或奥斯汀技术。术后4周、8周和6个月进行足底压力分析。此外，评估活动范围和美国矫形足踝协会（AOFAS）问卷。
两组的大脚趾和第一跖骨头区域，术后4周和6个月之间，最大力、峰值压力和力-时间积分显著增加（P≤0.001）。奥斯汀手术后6个月，AOFAS平均评分从术前的60.7提高到93.1，斯卡夫手术后6个月从术前的56.7提高到94.4。奥斯汀组的平均活动范围（ROM）为68.5°，术后6个月增加到平均ROM为75.5°，而斯卡夫组的平均ROM为67.8°，术后6个月增加到平均ROM为68.2°。
尽管手术技术和畸形程度不同，但两组之间的足底压力参数和功能结果没有差异。
