Surgical management of spiral oblique fractures of the fifth metatarsal leads to faster return to play in athletes: A systematic review.

ABSTRACT

PURPOSE: The purpose of this systematic review was to evaluate outcomes following both operative and nonoperative management of spiral oblique fractures of the fifth metatarsal. METHODS: During November 2023, the PubMed, Embase and Cochrane library databases were systematically reviewed to identify clinical studies examining outcomes following operative and nonoperative management of dancer's fractures. Data regarding subjective clinical outcomes, radiological outcomes, complications and failure rates were extracted and analysed. RESULTS: Ten studies were included in this review. In total, 125 patients underwent operative treatment for dancer's fractures and 365 patients underwent nonoperative treatment for dancer's fractures. The weighted mean follow-up in the operative cohort was 15.3 ± 32.7 months and the weighted mean follow-up in the nonoperative cohort was 30.6 ± 24.3 months. The overall union rate in the operative cohort was 99.2% and the overall union rate in the nonoperative cohort was 98.6%. The weighted mean time to return to sport was 15.4 ± 6.7 and 22.4 ± 4.4 weeks in the operative cohort and nonoperative cohort, respectively. The complication rate in the operative cohort and nonoperative cohort was 12.0% and 15.1%, respectively. CONCLUSION: This current systematic review demonstrated comparable radiographic outcomes together with low failure rate and low complication rate following both operative and nonoperative management of dancer's fracture at short-term follow-up. However, faster return to sport rates was observed in the operative cohort, suggesting that surgical management of displaced spiral oblique fractures of the fifth metatarsal should be the mainstay treatment option. However, the under-reporting of data, marked heterogeneity between studies and paucity of comparative studies limits the generation of any robust conclusions; thus, further high-quality comparative studies are warranted.
