Removal of os supranaviculare from a runner's painful foot: A case report
American Journal of Sports Medicine
There are many causes of foot pain in a runner. Painful os trigonum or painful accessory navicular are occasionally identified, but the several other possible ossicles (accessory ossification centers) in the foot have rarely, if ever, been implicated in foot pain. The authors' describe a recreational cross-country runner who developed pain at the site of an os supranaviculare in one foot. Although inflammation has been noted at this site in the past, no reference to removal of this bone can be found in the standard texts or journals of orthopaedic surgery, sports medicine, or podiatry.
