ch. 16 Osteochondrosis

Posted: May 6, 2012 in Traumatology

Osteochondrosis or Osgood-Schlatter disease is a family of orthopedic disorder of the joint that occur in children and adolescents and in rapidly growing animals, particularly pigs, horses, and dogs.

They are characterized by interruption of the blood supply of a bone, in particular to the epiphysis  followed by localized bony necrosis  and later, regrowth of the bone.

Osteochondrosis is an abnormality in this normal development of bones, and generally affects the joints. It resembles, but is distinct from Hip Displasia in many respects, in that it too is a developmental disorder of cartilage-bone formation.The ends of a bone grow in two places. Firstly, at the epiphyseal plate. This is a cartilaginous region of the growing bone, the location of the greatest part of growth. Secondly, the cartilage which overlies the end of the bone, at the joint, also grows, and becomes ossified at the junction of bone and cartilage.

Etiology :

The ultimate cause for these conditions is unknown, but the most commonly cited etiologic factors are rapid growth, heredity, trauma (or overuse), anatomic conformation, and dietary imbalances.
