简介 我们研究的目的是评估使用带蒂伸肌支持带皮瓣治疗尺侧腕伸肌 (ECU) 肌腱半脱位的患者的中期结果，包括术后肌腱稳定性控制。材料和方法 对 12 名接受伸肌支持带皮瓣治疗的 ECU 肌腱不稳定性患者进行回顾性评估。后续检查包括功能和放射学评估。记录运动范围、握力、DASH评分、PRWE评分、Krimmer评分和主观满意度。在手术前后进行旋转电影 MRI 以观察肌腱移位。结果腕部伸展65.8度（SD 10.0度），屈曲64.2度（SD 12.2度），桡偏15.8度（SD 6.0度），尺偏32.1度（SD 7.2度），旋前82.5度（SD 9.4度）和旋后85.0度（SD 9.0度）。平均握力为 30.5 千克（SD 8.9 千克）。六名患者的克里默评分结果为优秀，四名患者为良，一名患者为一般，一名患者为差。 DASH 和 PRWE 评分的平均值分别为 24.2 (SD 25.1) 和 32.2 (SD 29.4) 分。术前 MRI 显示 ECU 肌腱脱位 (n = 7) 或半脱位 (n = 5)。五名患者术后移位模式未发生变化。结论 带蒂伸肌支持带皮瓣治疗有症状的 ECU 不稳定性显示出良好至极好的效果，且主观满意度较高，与术后 ECU 肌腱移位无关
Introduction The aim of our study was the assessment of the mid-term outcome of patients treated with a pediculated extensor retinaculum flap for extensor carpi ulnaris (ECU) tendon subluxation including postoperative tendon stability control. Materials and methods Twelve patients treated with an extensor retinaculum flap for symptomatic ECU tendon instability were retrospectively evaluated. Follow-up examinations included functional and radiologic assessment. The range of motion, grip strength, DASH score, PRWE score, Krimmer score and subjective satisfaction were recorded. A rotation-movie MRI was conducted before and after surgery to visualize tendon displacement. Results Wrist extension was 65.8 degrees (SD 10.0 degrees), flexion 64.2 degrees (SD 12.2 degrees), radial deviation 15.8 degrees (SD 6.0 degrees), ulnar deviation 32.1 degrees (SD 7.2 degrees), pronation 82.5 degrees (SD 9.4 degrees) and supination 85.0 degrees (SD 9.0 degrees). Mean grip strength was 30.5 kg (SD 8.9 kg). Six patients presented an excellent, four a good, one a fair and one a poor result on the Krimmer score. The DASH and PRWE scores showed a mean of 24.2 (SD 25.1) and 32.2 (SD 29.4) points. MRI showed a dislocation (n = 7) or subluxation (n = 5) of the ECU tendon preoperatively. Five patients showed an unchanged displacement pattern postoperatively. Conclusion The pediculated extensor retinaculum flap as a treatment for a symptomatic ECU instability shows good to excellent results and a high subjective satisfaction independent of postoperative ECU tendon displacement
