OCD - Osteochondritis

Common diseases - OCD, Osteochondritis

Osteochondritis is an ossification problem that occurs during the development of an animal, generally less than one year old. Consequently, a small area of the bone remains cartilaginous at the level of the subchondral region (located under the joint cartilage). This abnormal cartilage is predisposed to trauma, and it can fissure and become detached, resulting in osteochondritis dissecans.

The cause has not yet been well established; however, this disease is considered to be multifactorial, implicating genetic and environmental factors.

  • The affected joints are: the shoulder, the elbow, the knee and the tarsus (heel)
  • The clinical signs are: pain and joint swelling, lameness and muscular atrophy.

If your young pet has these clinical signs, X-rays will be recommended in order to evaluate the bone at the joint level and to check for the presence of arthrosis.

Open surgery or arthroscopy is recommended for this condition. It consists of joint exploration and curetting of the affected area.

The prognosis is good for the shoulder lesions, but it is guarded for the other joints.
