Recently, my 13 year old son, who plays a lot of basketball, complained about having pain along the arches of his feet. Initially, I suspected it was probably “growing pains”. At this age, many kids start to have pain symptoms in their knees (Osgood-Schlatter disease) or heel area (Sever’s disease). Upon further inspection, we determined that he may have a condition called “accessory navicular syndrome” (ANS).
What is an Accessory Navicular?
An accessory navicular is an extra bone or piece of cartilage that some people are born with. It is located at the arch of the foot and is attached to the posterior tibialis tendon. This area can become irritated and inflamed by overuse (e.g. – running, jumping), friction from footwear rubbing the area, or an injury (e.g. – ankle/foot sprain). Common symptoms of ANS include: a bony prominence or bump at the midfoot/arch, tenderness at the top of the arch, redness and swelling, pain with weight bearing activities.
Is There a Treatment for Accessory Navicular Syndrome?
Treatment for ANS is geared towards reducing inflammation and correcting mechanical factors which may be contributing to the condition. Rest, applying cold packs, and taking NSAIDs will assist with inflammation. Sometimes wearing a walking boot is necessary to immobilize the ankle/foot to reduce stress on the area.
Physical therapy can assist with pain control as well as stretches and exercises to improve flexibility, strength, and stability to facilitate return to sports activities.
Orthotic inserts can also be used to promote better arch support and prevent reoccurrence of symptoms. Surgery may be required if these interventions are not effective. Fortunately, my son has responded well to the conservative treatment plan and is playing basketball without limitations.
