Abstract：
UNASSIGNED: This study aimed to investigate risk factors for recurrence of frozen shoulder after shoulder manipulation under ultrasound-guided cervical nerve root block (MUC).
UNASSIGNED: We retrospectively reviewed 135 frozen shoulders in 121 patients who underwent MUC. We defined frozen shoulder as a limited shoulder range of motion (ROM) (passive forward flexion <120°, external rotation <30°, or internal rotation lower than L3). Patients fulfilling any one criteria were considered to have frozen shoulder. If patients continued to have severe pain and limited ROM at 3 months after MUC, we defined as recurrence of frozen shoulder and they were offered a further MUC or arthroscopic capsular release (ACR). We compared the ROM, Constant Shoulder (CS) score, and University of California, Los Angeles score before and 3 months after MUC between patients with the successful of MUC group (Success group) with those recurrence of frozen shoulder who required a further MUC or ACR group (Recurrence group). Multiple logistic regression analysis was used to identify risk factors for recurrence of frozen shoulder after MUC.
UNASSIGNED: Patients who underwent MUC were retrospectively enrolled and divided into: the successful of MUC group (Success group, n = 112) and required a further MUC or ACR group (Recurrence group, n = 9). The Recurrence group had significantly lower external rotation and CS score before MUC than those in the Success group (P < .05). The Recurrence group showed significantly inferior all ROM and functional scores 3 months after MUC (P < .05). The levels of blood glucose and hemoglobin A1c both before and 3 months after MUC in the Recurrence group showed inferior compared with those of Success group. The difference, although not statistically significant, trended towards significance (before MUC/3 months after MUC; the glucose levels P = .06/.06, the hemoglobin A1c levels P = .07/.09, respectively). The visual analog scale pain score (at rest, during activity, at night) both before and 3 months after MUC in the Recurrence group showed significantly higher scores compared with those of Success group (P < .05). Multiple logistic regression analysis revealed that lower CS score before MUC was independent risk factor for recurrence of frozen shoulder after MUC.
UNASSIGNED: The overall incidence of recurrence of frozen shoulder after MUC was 7.4%. The lower CS score before MUC was an independent risk factor for recurrence of frozen shoulder after MUC. Moreover, patients in the Recurrence group tended to have poorly controlled diabetes and higher visual analog scale pain score both before and 3 months after MUC.

摘要：
■本研究旨在探讨超声引导下颈神经根阻滞（MUC）肩关节手术后冻结肩复发的危险因素。
■我们回顾性分析了121例接受MUC治疗的患者的135例冻结肩。我们将冻结肩定义为有限的肩活动范围（ROM）（被动前屈<120°，外旋转<30°,或内部旋转低于L3）。满足任何一个标准的患者被认为患有肩周炎。如果患者在MUC后3个月持续出现严重疼痛和有限的ROM，我们定义为冻结肩复发,并为他们提供了进一步的MUC或关节镜下包膜松解术(ACR).我们比较了ROM，恒定肩关节(CS)评分,和加州大学，MUC成功组（成功组）与需要进一步MUC或ACR组（复发组）的冻结肩复发患者之间的MUC之前和之后3个月的洛杉矶评分。采用多因素logistic回归分析确定MUC术后冻结肩复发的危险因素。
■对接受MUC的患者进行回顾性登记，并分为：MUC成功组（成功组，n=112），并且需要进一步的MUC或ACR组（复发组，n=9)。复发组外旋转和MUC前CS评分明显低于成功组(P<0.05)。复发组术后3个月的所有ROM和功能评分均明显低于MUC（P<0.05）。复发组MUC前和术后3个月的血糖和血红蛋白A1c水平均低于成功组。的区别,虽然没有统计学意义，趋势显着（MUC之前/MUC后3个月；葡萄糖水平P=.06/.06，血红蛋白A1c水平P=.07/.09，分别）。视觉模拟量表疼痛评分(静息时，活动期间,晚上），复发组MUC之前和之后3个月的得分均明显高于成功组（P<.05）。多因素logistic回归分析显示，MUC前CS评分较低是MUC后冻结肩复发的独立危险因素。
■MUC术后冻结肩复发的总发生率为7.4%。MUC前CS评分较低是MUC后冻结肩复发的独立危险因素。此外，复发组患者在MUC之前和之后3个月,糖尿病控制不佳,视觉模拟疼痛评分较高.
