If non-surgical treatment fails to relieve the symptoms of accessory navicular syndrome, surgery may be appropriate. Surgery may involve removing the accessory bone, reshaping the area, and repairing the posterior tibial tendon to improve its function. This extra bone is not needed for normal foot function.
Q: Can acupuncture help severe pain and swelling due to inflamed and torn posterior tibialis tendon? This resulted after an operation to remove navicular accessory bone 5 years ago. i have always had some chronic pain but now severe swelling and pain means I cannot work. My GP suggested normal pain killers / rest / physio / orthotics none of which gives me relief.
