apophysitis
Pronunciation: ap-oh-FY-sit-is
Inflammation of a growth plate attachment site in young athletes, commonly causing heel or knee pain.
Full Definition
Apophysitis refers to inflammation and irritation of an apophysis, which is a growth plate where tendons attach to bone in skeletally immature athletes. Common forms include Sever's disease (calcaneal apophysitis) affecting the heel and Osgood-Schlatter disease (tibial tubercle apophysitis) affecting the knee. These conditions typically occur during periods of rapid growth when the bone grows faster than the attached muscles and tendons, creating increased tension at the apophyseal insertion. Treatment is generally conservative, focusing on activity modification, stretching, and symptom management until skeletal maturity is reached.
Usage
Usage note: Specify anatomical location (e.g., 'calcaneal apophysitis' rather than just 'apophysitis').
