Operative Management for Symptomatic Accessory Navicular: A Systematic Review

This systematic review demonstrated satisfactory clinical and radiological outcomes following surgical intervention for symptomatic accessory navicular with moderate complication and failure rates. The most frequently utilized surgical technique was the Kidner procedure and its modifications, which demonstrated excellent clinical and radiological outcomes and is, therefore, the recommended surgical technique for the management of all subtypes of symptomatic AN. Concerning non-union rates were found in the arthrodesis, arthroeresis, and percutaneous drilling cohorts, which may predispose these techniques to failure in the long-term and, thus, are not recommended for the treatment of symptomatic AN. The lack of high-quality studies with a low level of evidence emphasizes the need for better quality comparative studies.<b>Levels of Evidence:</b> <i>IV</i>.
