This study evaluates the pressure distribution, the radiological and clinical results in patients before surgery and 6 months after scarf osteotomy for hallux valgus.
29 patients were examined before surgery and 6 months after surgery for symptomatic hallux valgus. Pedographic analysis was performed by dividing the footprint of the patients into 8 regions of interest. For each region the maximum mean pressure and the peak pressure were evaluated. Moreover, clinicofunctional results (AOFAS score) and radiological results were evaluated.
6 months postoperatively, maximum mean pressure increased significantly under the medial forefoot where as the peak pressure in this region revealed indifferent results. Significant improvement of clinicofunctional results and a significant reduction of the intermetatarsal and metatarsophalangeal angle could be seen.
These results confirm the clinical and radiological findings of other studies, but this study shows for the first time an increase of pressure under the first ray of the foot after hallux valgus surgery and an adaptation to the pressure distribution of normal feet.
本研究评估拇外翻患者手术前及采用斯卡夫截骨术治疗6个月后的压力分布、影像学及临床结果。
对29例有症状的拇外翻患者在手术前及术后6个月进行检查。通过将患者足底足迹划分为8个感兴趣区域进行足印分析。对每个区域评估最大平均压力和峰值压力。此外，还评估了临床功能结果（美国足踝外科协会评分）和影像学结果。
术后6个月，前足内侧下方的最大平均压力显著增加，而该区域的峰值压力结果无明显变化。临床功能结果有显著改善，跖间角和跖趾角显著减小。
这些结果证实了其他研究的临床和影像学发现，但本研究首次表明拇外翻手术后足第一跖骨下方压力增加，并与正常足的压力分布相适应。
