Excision Of Accessory Navicular Bone With Tibialis Posterior Tendon Reattachment: Does It Affect Patients Flatfoot?

Purpose: To evaluate the effect of reattachment of tibialis posterior tendon after excision of accessory navicular bone on flat foot patients clinically and radiologically. Methods: This prospective clinical trial included 10 patients with painful accessory navicular bone type II who were admitted and operated upon in minia university hospital from August 2024 to August 2025, accessory navicular bone excised and tibialis posterior tendon reattached to native bone with anchor mainly by double sutures , proximal which is very important for tensioning the tendon to improve the medial arch, distal for compression over the tendon ,then Demographic data, surgical complications, and follow-up period were documented. Functional outcome assessed clinically by AOFAS ,VAS scores and radiologically by meary ,pitch angles , navicular height. Results: Regarding clinical evaluation AOFAS and VAS scores show difference between pre and post operative scores which were highly significant (p value
