The Use of Acupuncture in the Management of Patients With Humeral Fractures: A Systematic Review and Meta-analysis

Objective: The purpose of this study was to conduct a systematic review and meta-analysis of the effects of acupuncture on humeral fractures. Methods: Randomized controlled trials were searched systematically from inception to January 2020 using the Cochrane Central Register of Controlled Trials, Embase, PubMed, Web of Science, China National Knowledge Infrastructure, and 7 Korean databases. Pain scale and Japanese Orthopaedic Association scores were the primary and secondary measurements. A risk-of-bias assessment and meta-analysis were conducted. Results: Seven randomized controlled trials were included in the systematic review; the quality of the studies was ambiguous. The meta-analysis showed that acupuncture improved the pain severity score compared with conventional therapies (standard mean difference = -4.55, 95% confidence interval, -7.48 to -1.61, I-2 = 98%, P < .00001) but did not improve the Japanese Orthopaedic Association score (standard mean difference = 4.99, 95% confidence interval, -0.31 to 10.30, I-2 = 99%, P < .00001). Conclusion: Our meta-analysis shows that acupuncture reduced pain after proximal humeral fracture, in addition to common rehabilitative modalities. However, the conclusion of this review should be cautiously applied in clinical practice owing to the low quality of the included studies.
