Differential diagnosis of osteochondroses

From top to bottom

• Kienbock disease (lunate)
• Osteochondritis dissecans of the elbow
• Panner disease (capitellum)
• Legg-Calve-Perthes disease (femoral head)
• Osteochondritis dissecans of the knee
• Sinding-Larsen-Johansson disease (patella inferior pole)
• Osgood-Schlatter disease (tibial tubercle)
• Sever disease (calcaneus)
• Kohler disease (navicular)
• Freiberg disease (metatarsal head)

Approach to the differential diagnosis of osteochondroses:

• Osteochondroses is the descriptive term given to a group of disorders that affect the progress of bone growth by bone necrosis
• It is only seen in children and adolescents who are still growing and affects the following areas:
  — Epiphyses – metatarsal head (Freiberg disease), femoral head (Legg-Calve-Perthes disease), capitellum (Panner disease)
  — Apophyses – calcaneus (Sever disease), tibial tuberosity (Osgood-Schlatter disease)
  — Primary ossification centers – lunate (Kienbock disease), navicular (Kohler disease), patella (Sinding-Larsen-Johansson disease)
