Abstract
OBJECTIVE: To compare the efficacy of intra-articular (IA) steroid injection and distension in patients with frozen shoulder. DATA SOURCES: Databases, including MEDLINE (via PubMed), Embase, Scopus, and Cochrane Library, were searched for studies published up to November 2016. STUDY SELECTION: We included all published randomized controlled trials (RCTs), quasi-experimental studies, and observational studies investigating the effectiveness of IA steroid injection, distension, and physiotherapy in patients with frozen shoulder. Sixteen RCTs and 1 observational study were enrolled in meta-analysis. DATA EXTRACTION: Full texts were independently reviewed, and quality of RCTs was assessed with The Cochrane Collaboration's tool. The primary outcome was functional improvement; the secondary outcomes included pain reduction and external rotation (ER) improvement. DATA SYNTHESIS: In pairwise meta-analysis, pooled standardized mean difference (SMD) of functional improvement and pain reduction revealed equal efficacy at 3 follow-up time points. With respect to ER improvement, distension has a superior effect compared with IA steroid injection in the short term [(2-4wk; SMD, -.36; 95% confidence interval [CI], -.68 to -.04) and medium term (6-16wk; SMD, -0.80; 95% CI, -1.32 to -0.29). The network meta-analysis indicated a better efficacy for distension than for IA steroid injection in ER improvement only in the medium term (6-16wk; SMD, -0.70; 95% CI, -1.19 to -0.21). CONCLUSIONS: IA steroid injection was as effective as distension in shoulder function improvement, pain reduction, and increasing ER of the shoulder. Distension yielded better ER improvement in the medium term but to a minor extent in the long term. For patients with predominant ER limitation, early distension could be considered the primary choice of treatment.
