UNASSIGNED：本研究报告了根据CT/MRI检查对12例IV期Müller-Weiss病（MWD）进行的个体化手术治疗。
未经批准：总共，将2015年至2019年我院诊断为IV期MWD的12例纳入回顾性研究。术前和术后评估相关临床结果。
UNASSIGNED：随访结果显示，所有病例的治疗结果均令人满意。所有病例均表现为足中背压痛和慢性疼痛。三例也表现为中足外侧的压痛和疼痛，CT/MRI显示跟骨长方体关节炎。美国骨科足踝协会（AOFAS）评分从术前62.5±6.8（范围：53-74）提高到术后95.3±7.2（范围：73-100）（P<0.005）。视觉模拟量表（VAS）评分从术前4.2±0.9（范围：3-5.5）下降至术后0.5±0.3（范围：0-2）（P<0.001）。在脚的承重侧视图上，Tomeno-Méary角（TMlat）从术前-11.2±4.2（范围：-17.2至-2.8）度变为术后-2.4±3.9（范围：-10.2至5.2）度（P<0.001）。
UNASSIGNED：距骨-舟骨关节和邻近受影响关节的融合提供了良好的临床结果。CT/MRI扫描有助于识别邻近的关节关节炎，并为IV期MWD的单独治疗提供指征。
UNASSIGNED: This
study reported the individual surgical treatment of 12 cases with stage IV Müller-Weiss disease (MWD) according to CT/MRI examination.
UNASSIGNED: In total, 12 cases diagnosed with stage IV MWD in our hospital from 2015 to 2019 were included in the retrospective
study. Relevant clinical outcomes were evaluated preoperatively and postoperatively.
UNASSIGNED: The follow-up results showed satisfactory outcomes in all cases. All the cases were presented with tenderness and chronic pain on the midfoot dorsum, and three cases were also presented with tenderness and pain on the lateral side of the midfoot, in which calcaneal cuboid arthritis was revealed by CT/MRI. The American Orthopedic Foot and Ankle Society (AOFAS) scores elevated from 62.5 ± 6.8 (range: 53-74) preoperatively to 95.3 ± 7.2 (range: 73-100) postoperatively (P < 0.005). The Visual Analog Scale (VAS) scores declined from 4.2 ± 0.9 (range: 3-5.5) preoperatively to 0.5 ± 0.3 (range: 0-2) postoperatively (P < 0.001). On the weight-bearing lateral view of the foot, the Tomeno-Méary angle (TM lat) changed from -11.2 ± 4.2 (range: -17.2 to -2.8) degrees preoperatively to -2.4 ± 3.9 (range: -10.2 to 5.2) degrees postoperatively (P < 0.001).
UNASSIGNED: The fusion of the talus-navicular joint and the adjacent affected joint provide good clinical outcomes. The CT/MRI scans are helpful to identify the adjacent joint arthritis and provide indications for individual treatment for Stage IV MWD.
