ABSTRACT
PURPOSE: To synthesize and analyze the existing literature and report on the outcomes of arthroscopic surgery for the treatment of scaphoid non-union (SNU). METHODS: This systematic review conforms to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The authors conducted a search using Medline and Embase databases. Studies that reported outcomes on arthroscopic nonvascularized bone graft for SNU treatment, with no limits to follow-up, sample sizes or prevalence were included. RESULTS: We found 17 eligible studies composed of 20 datasets, and all assessed nonvascularized arthroscopic treatment for SNU, with a mean follow-up that ranged from 6 to 38.5 months. Union rates ranged between 86% and 100%, and none of the studies reported any other complications than non-union following arthroscopic SNU. CONCLUSIONS: The present systematic review found union rates ranging between 86% and 100%, with a time to union ranging from 2.3 to 7.8 months. Furthermore, the included studies reported satisfactory clinical scores, and the complication rate of non-union ranged between 0% and 14%. LEVEL OF EVIDENCE: Level IV, systematic review of level II-IV studies.
ABSTRACT
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.
