Freiberg’s infarction, also known as Freiberg’s disease or osteochondrosis of the metatarsal head, is a condition in which there is a loss of blood supply (avascular necrosis) to the head of the metatarsal bone in the foot. This can cause pain, swelling, and stiffness in the affected foot, and may lead to arthritis or joint deformity over time.
The exact cause of Freiberg’s infarction is not fully understood, but it is believed to be related to repeated trauma or injury to the metatarsal head, which can disrupt the blood supply to the bone. The condition is most commonly seen in adolescent girls and young women, and may be associated with wearing high-heeled shoes or engaging in activities that involve repetitive impact on the foot, such as running or jumping.
Treatment for Freiberg’s infarction typically involves rest, ice, and anti-inflammatory medication to reduce pain and inflammation in the affected foot. Immobilization in a cast or boot may also be recommended to allow the bone to heal. In more severe cases, surgery may be necessary to remove damaged bone or reshape the joint to reduce pain and improve function.
Overall, the prognosis for Freiberg’s infarction depends on the severity of the condition and the effectiveness of the chosen treatment. With appropriate care, many patients are able to manage their symptoms and maintain good foot function over time.
