Studies have shown that sesamoidectomy provides good clinical outcomes; however, concern exists regarding complications occurring after resection of 1 or both sesamoid bones. The purpose of the present systematic review was to evaluate the current evidence on sesamoidectomy for the treatment of hallux sesamoid disorders. A systematic search of the MEDLINE, Embase, and Cochrane Library databases was performed during October 2017. The included studies were evaluated for the level of evidence and quality of evidence using the Coleman Methodology Score. Variable reporting outcomes data, clinical outcomes, and percentage of patients returning to sports at their previous level were evaluated. Ten studies, totaling 196 feet, were included. The weighted mean patient age was 36.6 ± 11.0 years, and the weighted mean follow-up duration was 45.1 ± 19.3 months. The mean visual analog scale score improved from 6.5 ± 0.3 to 1.2 ± 0.5. The mean postoperative American Orthopaedic Foot and Ankle Society ankle-hindfoot scale score was 92.7 ± 2.7. Six studies demonstrated that 94.4% of patients returned to sports, with 90.0% returning to their previous level, at a mean of 11.8 ± 1.8 weeks. The mean hallux valgus angle increased from 13.1° ± 2.1° preoperatively to 14.8° ± 3.7° postoperatively (p = .470), and the mean intermetatarsal angle increased from 8.7° ± 0.8° to 9.7° ± 0.8° (p = .180). Overall complication rate was 22.5% and the revision rate was 3.0%. The present systematic review has demonstrated that sesamoidectomy for hallux sesamoids disorders yields good clinical outcomes and a high rate of return to sports in the short term, albeit with a high complication rate of 22.5%.Level of Clinical Evidence: 4
