Terrible triad injury of the elbow (TTIE) is a severe high‑energy injury to the elbow, mainly including elbow dislocation, coronoid fracture and radial head fracture. It is difficult to maintain the stability of the elbow joint using traditional conservative treatment, and there is a high risk of redislocation and various complications. Therefore, surgical treatment is currently advocated, mainly for repairing damaged ligaments and reconstructing bony structures, but there is still controversy about the treatment plan for the radial head. The current meta‑analysis was conducted to compare the differences in efficacy of radial head arthroplasty (RHA) and open reduction internal fixation (ORIF) in the treatment of TTIE. Published literature related to the treatment (either ORIF or RHA) of TTIE was searched for in Embase, PubMed, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, ProQuest Dissertations and Theses, Cochrane Library and Chinese Biomedical Literature Database. According to the search strategy, a total of 1,928 related publications were retrieved. The patient must have been diagnosed with TTIE and required surgery on the radial head. The interventions were RHA and ORIF. Non‑case‑control studies, case reports, review articles, letters, duplicate reports and literature without sufficient relevant data were excluded. The quality of the literature was evaluated according to the Cochrane systematic review methodology and the Jadad scale. After data extraction, meta‑analysis was performed using ReviewManager 5.4 software (Cochrane). A total of 15 studies involving 455 patients (189 who underwent RHA and 266 who underwent ORIF) were included. Range of motion (ROM) of the forearm (pronation‑supination arc) after surgery in the RHA group [95% CI (0.28, 9.59); P=0.04] was found to be significantly superior to the ORIF group, with a lower incidence of complications [95% CI (0.22, 0.84); P=0.01]. However, there was no statistically significant difference for the Mayo Elbow Performance Score, Disabilities of the Arm, Shoulder and Hand Score nor for ROM of the elbow (flexion‑extension arc). Overall, compared with the ORIF group, the RHA group had better forearm rotational ROM and fewer complications after surgery. Therefore, RHA was found to be superior to ORIF in the treatment of TTIE.
