Preoperative assessment of symptomatic bunionette deformity: radiologic findings.

A symptomatic bunionette (tailor's bunion) is a painful bony prominence on the lateral side of the fifth metatarsal head, often associated with an inflamed thickened adventitious bursa and hypertrophic keratoses or calluses. The diagnosis is based on the presence of pain that is most often caused by pressure from footwear. The purpose of this essay is to illustrate the radiographic abnormalities of bunionettes and useful angular measurements as they relate to the preoperative evaluation of symptomatic bunionette deformity.
