Incidental Bilateral Scaphotrapezial Coalition in a High-Level Throwing Athlete: A Case Report

Scaphotrapezial coalition is a rare carpal coalition and historically associated with congenital syndromes because it spans 2 carpal rows. We present the case of an 18-year-old collegiate baseball pitcher who was incidentally found to have bilateral scaphotrapezial coalition. He had no history of wrist pain and no functional limitations on physical examination. He had no family history of this condition and no personal history of congenital abnormalities.

Bilateral scaphotrapezial coalition can be an incidental and asymptomatic finding that is present even in high-level throwing athletes.
