The athlete's hand: Ligament and tendon injury

摘要

Hand injuries are common, accounting for up to 20% of emergency department visits nationwide. An understanding of the complex and detailed anatomical relationships of small joints facilitates the accurate diagnosis of many common sports-related injuries of the hand. We review the common ligamentous and tendinous injuries of the hand including collateral ligament injuries, gamekeeper's thumb, extensor mechanism injuries, pulley injuries, boutonniere deformities, and mallet and jersey lesions. The mechanism of injury, clinical presentation and treatment, pertinent anatomy, and imaging findings are discussed.
