The purpose of the study was to compare outcomes of fully-arthroscopic reduction and internal fixation (ARIF) versus open reduction and internal fixation (ORIF) to treat acute traumatic lunate fractures. A literature search was conducted using Medline and Embase. Demographic data and outcomes were extracted for included studies. The search identified 2146 references: 17 articles were included, reporting on 20 cases (4 ARIF and 16 ORIF). No differences between ARIF and ORIF were found in rates of union (100% vs 93%, P = 1.000), grip strengths (mean difference, 8%; 95%CI, -16 to 31; P = 0.592), rates of return to work (100% vs 100%, P = 1.000), or ranges of motion (mean difference, 28°; 95%CI, -25 to 80; P = 0.426). Lunate fractures were not identified in 6 of the 19 radiographs, but were identified in all CT scans. There were no differences in outcomes between ARIF and ORIF for the treatment of fresh lunate fractures. The authors recommend surgeons to perform CT scans when diagnosing high-energy wrist trauma so as not to overlook lunate fractures. LEVEL OF EVIDENCE: Level IV.
