Osteochondrosis: important points and eponyms

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
  1. Nonarticular osteochondroses occur at the following locations:
  • Tendinous attachments – Osgood-Schlatter syndrome, Monde-Felix disease
  • Ligamentous attachments – Vertebral ring
  • Impact sites – Sever disease
  1. Physeal osteochondroses involve the following:
  • Long bones – Tibia vara (Blount disease)
  • Scheuermann disease
