Osteochondrosis / Stress Frx of Medial Epicondyle
Wheeless' Textbook of Orthopaedics
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

Sever disease is a painful inflammation of the calcaneal apophysis. It is classified with the child and adolescent nonarticular osteochondroses. (The other disease in this group is Iselin disease, which is inflammation of the base of the fifth metatarsal.) The etiology of pain in Sever disease is believed to be repetitive trauma to the weaker structure of the apophysis, induced by the pull of the tendo Achilles on its insertion. This results in a clinical picture of heel pain in a growing active child, which worsens with activity.

Sever's disease is a term used to describe inflammation of the calcaneal apophysis which occurs in children and adolescents. Highly Reputable

In children, there is an area on the heel bone where the bone grows that is called the growth plate, or apophysis. Calcaneal apophysitis, also called Sever's disease, is inflammation of the calcaneal growth plate that causes pain in the heel. It is the most common cause of heel pain in children, adolescents, and teenagers.

Sever's Disease: A Common Cause of Heel Pain

Sinding-Larsen-Johansson syndrome is inflammation of the kneecap (patella) at its lowest point. This is the site of origin of the patellar tendon. There is traction on the kneecap at this point due to action of the large, powerful thigh muscle (quadriceps), as well as with deep bending of the knee. The injury is due to repeated stress or vigorous exercise. It is a temporary condition of the patella that is uncommon after age 16. It is the children’s equivalent of patellar tendinitis (jumper’s knee).

Sinding Larsen-Johannson disease may cause or feature knee pain due to osteochondritis contusion and subsequent tendonitis in the proximal attachment of the patellar tendon

VCU Health System Pediatric Radiology Case of the Week
Disease Images, diagnosis, Treatment options
Pain, swelling, tenderness of inferior patellar pole at origin of the patellar tendon
Osteochondrosis involving the apex of the patella 10-14 years
Traction phenomenon - tendonitis proximal patellar tendon
Calcification and ossification on elongated inferior patellar pole
Natural duration of the disease is approximately 3 to 12 months

contusion and subsequent tendonitis in the proximal attachment of the patellar tendon can be followed by calcification, ossification, or frank inferior pole avulsion fractures that produce one or more distinct ossicles. per Stedman's dictionary: "apophysitis of the distal pole of the patella" symptoms: tenderness and soft tissue swelling over the lower pole of the patella aggregated by activity xray findings: osseous fragmentation of patella
