Assessing the Outcomes Associated with Accessory Navicular Bone Surgery-a Systematic Review.

purpose of reviewThe purpose of this review is to evaluate the existing literature in order to compare the clinical outcomes and complications associated with the kidner procedure and simple excision procedure. Furthermore, this review will help determine if one procedure is advantageous over the other in treating accessory navicular among patients. RECENT

findingsPrevious research on this topic has seen a low success rate in treating patients with symptomatic accessory navicular using conservative treatment options such as shoe-wear modification, braces, and/or nonsteroidal anti-inflammatory. Surgical treatment such as simple excision and kidner procedure has shown to have minor complications including scarring and wound irritation with a generally high satisfaction rate from patients. However, cases where patients that had planovalgus or hindfoot valgus accompanying the accessory navicular were required to undergo revision surgery to treat the recurrent pain following the kidner procedure. Similarly, patients that underwent simple excision procedure with having flat foot were unable to complete the heel test postoperatively despite not reporting feelings of pain. Both simple excision and the Kidner procedure appear to be efficacious procedures with low complication profiles and high rates of patient satisfaction. Moreover, it has appeared that the female demographic is more likely to present symptomatic accessory navicular and undergo surgical treatment. To further explore the ideal indication for each, more prospective comparative studies are needed as well as radiological assessments pre- and post-operatively to evaluate anatomical changes in the posterior tibialis tendon area between both procedures.
