Endoscopic resection of symptomatic talocalcaneal coalition in adolescents using a posterior approach / 中华创伤骨科杂志

ABSTRACT

Objective:To evaluate the outcomes of endoscopic resection of symptomatic talocalcaneal coalitions in adolescents using a posterior approach.Methods:A retrospective case-series study was performed to analyze the data of 15 adolescent patients (16 feet) with symptomatic talocalcaneal coalitions (TCC) who had been treated by posterior arthroscopy from February 2017 to December 2020 at Department of Orthopaedics, Xuzhou Central Hospital. There were 11 boys and 4 girls with an average of 14.3 years (from 11 to 17 years). The left side was affected in 9 and the right side in 5 patients, and both sides were involved in one. Ten patients had a history of ankle sprain. The clinical outcomes were evaluated by visual analogue scale (VAS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score and 36-item short form health survey (SF-36) postoperatively.Results:The 15 patients were followed up for a mean time of 19.9 months (from 12 to 36 months). At the final follow-up, the VAS significantly decreased from preoperative 6 (6, 7) points to 1 (1, 3) point, the AOFAS ankle-hindfoot score significantly increased from preoperative (54.1±10.4) points to (90.0±16.6) points, and the SF-36 score significantly improved from preoperative (55.5±12.7) points to (88.7±6.5) points ( P<0.05). Follow-ups found such complications as infection, TCC recurrence or osteoarthritis in none of the patients. Conclusion:Endoscopic TCC resection using a posterior approach is an effective surgery for symptomatic TCC in adolescents, showing advantages of limited invasion, fast recovery, a low rate of postoperative complications and precise resection.
