超声引导下关节腔注射联合关节囊扩张治疗冻结肩

目的 观察超声引导下肩关节腔注射联合关节囊扩张治疗冻结肩的价值。方法 将100例临床诊断为冻结肩的患者随机分为试验组和对照组，每组各50例。对试验组进行连续3次超声引导下肩关节腔注射联合关节囊扩张治疗，对照组仅行连续3次单纯超声引导下关节腔注射治疗；分别于治疗前、治疗后6周和12周对肩关节疼痛（VAS）和主动活动范围（AROM）进行评分。结果 治疗后6周及12周，2组VAS及AROM均较治疗前明显改善（P均<0.05）。治疗后6周和12周，2组间VAS评分差异均无统计学意义（P均>0.05）；而试验组AROM评分均明显高于对照组（P<0.05）。结论 超声引导下肩关节腔注射联合关节囊扩张和单纯关节腔注射法均能有效改善冻结肩患者疼痛，而在改善肩关节功能方面，超声引导下肩关节腔注射联合关节囊扩张法的短、中期疗效明显优于单纯注射法。

Ultrasound-guided joint injection combined with capsular distension for treatment of frozen shoulder

Objective To explore the effect of ultrasound-guided joint injection combined with capsular distension for treatment of frozen shoulder.Methods Totally 100 patients clinically diagnosed as frozen shoulder were randomly and evenly divided into experiment group and control group (each n=50). Patients in experiment group were treated with 3 times consecutive ultrasound-guided joint injection combined with distension, while patients in control group were treated with ultrasound-guided joint injection alone. All the patients were scored with visual analogue scale (VAS) and active range of movement (AROM) before, 6 and 12 weeks after the treatment.Results Both VAS and AROM scores were significantly improved 6 and 12 weeks after treatment than before treatment in each group (all P<0.05). There was no statistical difference in VAS scores 6 and 12 weeks after treatment between the two groups (both P>0.05). However, AROM scores were significantly greater in experiment group than those in control group (both P<0.05).Conclusion Both ultrasound-guided joint injection and joint injection combined with distension can effectively relieve the pain of patients with frozen shoulder. However, ultrasound-guided injection combined with distension is better than ultrasound-guided injection for improvement of short-term and medium-term shoulder function.
