Adhesive capsulitis, or frozen shoulder, is a painful and disabling condition characterized by progressive restriction of shoulder movement. Hydrodilatation, a minimally invasive procedure involving joint capsule distension, has been proposed as an effective treatment option. This study evaluates the functional outcomes of hydrodilatation in patients with adhesive capsulitis using the Constant-Murley score (CMS) and American Shoulder and Elbow Surgeons (ASES) score, along with pre- and post-procedure range of motion (ROM) assessments.
A prospective observational study was conducted on 30 patients diagnosed with adhesive capsulitis who underwent hydrodilatation. Functional and ROM improvements were assessed at baseline, post-procedure, 1 month, 3 months, 6 months, and 1 year. Data were analyzed using paired t-tests, and P < 0.05 was considered statistically significant.
The mean age of participants was 47.7 ± 9.8 years. The study population comprised 14 males (46.7%) and 16 females (53.3%), indicating a slightly higher prevalence among females. Significant improvements were observed in active and passive abduction, adduction, forward flexion, and external rotation (P < 0.001). Internal rotation restriction reduced from 59.1% to 40.9% (P < 0.001). Functional scores (ASES and CMS) showed progressive improvement, with ASES increasing from 41.1 ± 6.1 to 65.9 ± 8.4 and CMS from 44.4 ± 5.8 to 64.8 ± 9.1 at 1 year (P < 0.001).
Hydrodilatation is an effective and well-tolerated intervention for improving shoulder function in adhesive capsulitis, with sustained benefits up to 1 year. Future studies should focus on standardizing treatment protocols and optimizing patient selection criteria.
粘连性关节囊炎，即肩周炎，是一种以肩部活动逐渐受限为特征的疼痛且致残的病症。关节囊扩张术作为一种涉及关节囊扩张的微创手术，已被提议作为一种有效的治疗选择。本研究使用Constant-Murley评分（CMS）和美国肩肘外科医师学会（ASES）评分，以及术前和术后的活动范围（ROM）评估，来评价关节囊扩张术对粘连性关节囊炎患者的功能结局。
对30例诊断为粘连性关节囊炎并接受关节囊扩张术的患者进行了一项前瞻性观察研究。在基线、术后、1个月、3个月、6个月和1年时评估功能和ROM的改善情况。使用配对t检验分析数据，P < 0.05被认为具有统计学意义。
参与者的平均年龄为47.7±9.8岁。研究人群包括14名男性（46.7%）和16名女性（53.3%），表明女性患病率略高。主动和被动外展、内收、前屈和外旋均有显著改善（P < 0.001）。内旋受限率从59.1%降至40.9%（P < 0.001）。功能评分（ASES和CMS）呈逐步改善，1年时ASES从41.1±6.1增至65.9±8.4，CMS从44.4±5.8增至64.8±9.1（P < 0.001）。
关节囊扩张术是改善粘连性关节囊炎肩部功能的一种有效且耐受性良好的干预措施，长达1年都有持续益处。未来的研究应专注于规范治疗方案和优化患者选择标准。
