Freiberg's disease is rare condition that primarily affects the second or third metatarsal (the long bones of the foot). Although people of all ages can be affected by this condition, Freiberg's disease is most commonly diagnosed during adolescence through the second decade of life. Common signs and symptoms include pain and stiffness in the front of the foot, which often leads to a limp. Affected people may also experience swelling, limited range of motion, and tenderness of the affected foot. Symptoms are generally triggered by weight-bearing activities, including walking. The exact underlying cause of Freiberg's disease is currently unknown. Treatment depends on many factors, including the severity of condition; the signs and symptoms present; and the age of the patient.

The exact cause of Freiberg's disease is poorly understood. Some scientists believe that it is a multifactorial condition which is likely associated with the effects of multiple genes in combination with lifestyle and environmental factors. However, most current theories are centered on whether the triggering event is predominantly traumatic (injury-related) or vascular (consistent with avascular necrosis - an injury to the blood supply of the affected part of the foot).

Occasionally, people with Freiberg's disease have no obvious symptoms of the condition, with changes noted only on X-rays taken for other purposes. Whether these people will later develop symptoms is not known.

A diagnosis of Freiberg's disease is often suspected based on the presence of characteristic signs and symptoms. An X-ray, magnetic resonance imaging (MRI), and/or bone scan can then be ordered to confirm the diagnosis. Other testing such as laboratory studies may also be recommended to rule out other conditions that cause similar features.

If other treatments are not effective, surgery may be necessary. Medscape Reference's Web site offers more specific information regarding the different surgical procedures used to treat Freiberg's disease. Please click on the link to access the resource.
