Traction apophysitis
Pronunciation: ap-oh-FY-sigh-tis
Inflammation of bone growth centers due to repetitive pulling forces from attached tendons or muscles.
Full Definition
Traction apophysitis is an overuse injury affecting apophyses (secondary growth centers) in skeletally immature patients, caused by repetitive traction forces from muscular or tendinous attachments. Common locations include the tibial tubercle (Osgood-Schlatter disease), calcaneal apophysis (Sever's disease), and medial epicondyle (little leaguer's elbow). The condition occurs when repetitive stress exceeds the apophyseal growth plate's ability to adapt, leading to inflammation, pain, and potential growth disturbances. Recognition is important in pediatric trauma to differentiate from acute fractures and guide appropriate activity modification.
Usage
Usage note: Common in pediatric and adolescent populations with sports-related complaints.
