Abstract：
UNASSIGNED: Midfoot arthrodesis is regarded as the main surgical approach for treating Müller-Weiss disease (MWD). This study aimed to investigate the incidence of postoperative pain during MWD treatment through midfoot reduction or malreduction during arthrodesis and to explore the factors influencing postoperative pain in patients with MWD.
UNASSIGNED: A total of 67 patients with MWD were recruited and divided into two groups according to whether midfoot alignment was reduced: reduction group (n = 38) and malreduction group (n = 29). Demographic characteristics before the operation and at the last follow-up, as well as clinical and radiographic parameters, were compared between the two groups. Clinical parameters included the American Orthopaedic Foot & Ankle Society score and visual analog scale score, whereas radiographic parameters included the calcaneal pitch angle, lateral Meary\'s angle, talometatarsal-1 angle dorsoplantar (TMT1dp), talocalcaneal angle dorsoplantar (Kite angle), talonavicular coverage angle, and medial navicular pole extrusion. Postoperative complications and incidence of midfoot pain were evaluated at the last follow-up visit.
UNASSIGNED: The reduction group exhibited better clinical and radiological parameters, including the TMT1dp and medial navicular pole extrusion, than the malreduction group at the last follow-up (all P < .05). However, the calcaneal pitch angle, lateral Meary\'s angle, Kite angle, and talonavicular coverage angle did not significantly differ between the two groups (all P > .05). The overall incidence of midfoot pain was 26.4%. The reduction group showed a lower incidence of medial pain than the malreduction group (15.7% vs. 40.0%, P < .05). Regression analysis revealed that midfoot abduction, represented by the TMT1dp, was a critical factor for midfoot arthrodesis failure and that medial navicular pole extrusion was not correlated with postoperative midfoot pain.
UNASSIGNED: Midfoot reduction arthrodesis yields better clinical outcomes than malreduction arthrodesis. The TMT1dp, representing midfoot abduction, is a key factor for midfoot arthrodesis failure. The extruded medial navicular bone may not affect postoperative medial midfoot pain.
UNASSIGNED: Level III, retrospective comparative study.

摘要：
■中足关节固定术被认为是治疗Müller-Weiss病（MWD）的主要手术方法。本研究旨在探讨MWD患者在关节固定术中足中复位或复位不良治疗中术后疼痛的发生率，并探讨影响MWD患者术后疼痛的因素。
■共纳入67例MWD患者，根据是否减少中足对齐分为两组：减少组（n=38）和减少不良组（n=29）。手术前和最后一次随访时的人口统计特征，以及临床和影像学参数，对两组进行比较。临床参数包括美国骨科足踝协会评分和视觉模拟量表评分，而射线照相参数包括跟骨俯仰角，横向米里角，足趾1角足底（TMT1dp），足趾角（风筝角），距骨覆盖角,和内侧舟骨极挤压。在最后一次随访时评估术后并发症和中足疼痛的发生率。
■减少组表现出更好的临床和放射学参数，包括TMT1dp和内侧舟骨极挤压，末次随访时，不良复位组比较（均P<0.05）。然而,跟骨俯仰角,横向米里角，风筝角度,两组间无显著差异(P均>.05)。中足疼痛的总发生率为26.4%。复位组的内侧疼痛发生率低于复位不良组(15.7%vs.40.0%,P<0.05)。回归分析显示中足外展,以TMT1dp为代表，是中足关节固定术失败的关键因素，内侧舟骨极挤压与术后中足疼痛无关。
■中足减少关节固定术比减少关节固定术产生更好的临床结果。TMT1dp,代表中足绑架，是中足关节固定术失败的关键因素。挤压的内侧舟骨可能不会影响术后内侧中足疼痛。
■三级,回顾性比较研究。
