Abstract：
Mueller-Weiss Syndrome (MWS), characterized by spontaneous adult-onset tarsal navicular osteonecrosis, is an uncommon cause of chronic midfoot pain that can lead to functional impairment and progressive deformities. This study aimed to present clinical and radiological outcomes of talonavicular-cuneiform (TNC) arthrodesis in the treatment of patients with MWS. A retrospective study was performed on 8 consecutive patients (6 female, 2 male; mean age = 50 years; range = 33-64) who underwent TNC arthrodesis using plate fixation with autologous bone grafting for the treatment of MWS. To evaluate clinical status, the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Midfoot Score was performed immediately preoperatively and at the final follow-up. In radiographic evaluation, talus-first metatarsal angle (Meary\'s angle) was measured preoperatively and at the final follow-up. Solid fusion was also examined on postoperative radiographs and computerised tomography. The mean follow-up was 35 months (range = 24-52). The mean AOFAS improved from 37 (range = 24-53) preoperatively to 85 (range = 80-93) at the final follow-up (p < 0.001). No major intra- operative complications were observed in any of the patients. According to the Maceira and Rochera radiological staging system, 5 feet was stage 3, and 3 feet was stage 4. The mean union time was 10 months (range = 5-15). Radiographic solid fusion was achieved in all but one foot that developed talonavicular non-union. TNC arthrodesis using plate fixation with autologous bone grafting seems to be an effective surgical method for reconstruction of MWS.
摘要：
Mueller-Weiss综合征（MWS）以自发性成人起病的骨舟骨坏死为特征，是一种罕见的慢性足中疼痛的原因，可导致功能障碍和进行性畸形。这项研究旨在介绍在治疗MWS患者中，距骨楔状骨（TNC）关节固定术的临床和放射学结果。对8例连续患者进行了回顾性研究（6例女性，2名男性；平均年龄=50岁；范围=33-64），使用钢板固定和自体植骨治疗MWS进行了TNC关节固定术。为了评估临床状态，术前和最后随访时立即进行美国骨科足踝协会(AOFAS)踝关节-中足评分.在射线照相评估中，术前和最后随访时测量距骨第一跖骨角(Meary\s角)。还在术后X光片和计算机断层扫描中检查了固体融合。平均随访35个月（范围=24-52）。平均AOFAS从术前的37（范围=24-53）改善到最终随访时的85（范围=80-93）（p<0.001）。所有患者均未出现术中严重并发症。根据Maceira和Rochera放射分期系统,5英尺是第3阶段，3英尺是第4阶段。平均愈合时间为10个月（范围=5-15）。除一只脚出现距骨骨不连外，所有脚都实现了射线照相固体融合。使用钢板固定和自体植骨的TNC关节固定术似乎是重建MWS的有效手术方法。
