Osteochondrosis / Stress Frx of Medial Epicondyle

- See: Pediatric Elbow Injuries - Discussion: - a traction apophysisitis of the medial epicondyle which needs to be distinguished from avulsion frx of the medial epicondyle - the medial epicondyle is an apophysis which is connected to the MCL as well as being connected to the flexor-pronator mass; - both of these structures will stress the apophysis w/ valgus stress; - radiographs: - medial epicondyle fuses at age 17 years; - look for fatigue fractures of the medial epicondyle: - enlargement and fragmentation of the apophysis may be seen; - treatment: - a true apophysisitis of the medial epicondyle is treated non-operatively w/ rest ands strict avoidance of throwing activities; - a displaced traction apophysisitis is more consistent w/ a avulsion frx of the medial epicondyle and may need to be treated operatively;
