Overview
Osteochondritis of the tarsal or metatarsal bone is a condition that affects the bones in the foot, specifically the tarsal bones (which make up the midfoot and hindfoot) and the metatarsal bones (the long bones in the front part of the foot). This condition involves inflammation and sometimes damage to the bone and its overlying cartilage, often due to disruption of the blood supply to a small area of bone. This process is also known as osteochondrosis or avascular necrosis when it affects these specific foot bones. Well-known forms include Köhler disease (affecting the navicular bone in children) and Freiberg disease (affecting the metatarsal head, usually the second metatarsal, in adolescents and young adults). Patients typically experience foot pain, swelling, and difficulty walking or bearing weight on the affected foot. The pain may worsen with activity and improve with rest. In some cases, the affected bone may temporarily lose its normal shape before healing. The condition is most commonly seen in children and adolescents during periods of rapid growth. Treatment usually focuses on reducing pain and protecting the affected bone while it heals. This may include rest, activity modification, supportive footwear, orthotics, casting or bracing, and anti-inflammatory medications. In most cases, the bone heals on its own over time, especially in younger patients. Surgery is rarely needed but may be considered if conservative measures fail or if there is significant bone or cartilage damage.
