Classification of Osteochondrosis

Old classifications:

1. Burrows’s classification: He divided into Pressure, traction, and atavistic types.
2. Goff’s classification: He classified into compression, tension, and atavistic types.

These systems were inadequate.

 

Siffer’s Classification:

Siffer proposed a classification that divided osteochondroses into articular, nonarticular, and physeal types; this schema is largely accepted today.

 

1. Articular osteochondroses exhibit the following characteristics:

• Primary involvement of the articular and epiphyseal cartilage and a subjacent endochondral ossification center – Freiberg disease ^[4]
• Secondary involvement of the articular and epiphyseal cartilage as a consequence of ischemic necrosis of subjacent bone – Perthes disease, Köhler disease, osteochondritis dissecans

2. Nonarticular osteochondroses occur at the following locations:

• Tendinous attachments – Osgood-Schlatter syndrome, Monde-Felix disease
• Ligamentous attachments – Vertebral ring
• Impact sites – Sever disease

3. Physeal osteochondroses involve the following:

• Long bones – Tibia vara (Blount disease)
• Scheuermann disease
