Metacarpal Synostosis

Metacarpal synostosis is a rare congenital condition characterized by the fusion of two or more metacarpal bones in the hand. This fusion can occur between any of the five metacarpal bones, leading to limited mobility and functionality of the affected hand.

Symptoms

Individuals with metacarpal synostosis may experience stiffness, reduced range of motion, and deformity in the affected hand. The severity of symptoms can vary depending on the extent of fusion and the specific metacarpal bones involved.

Causes

The exact cause of metacarpal synostosis is not well understood. It is believed to result from abnormal development during fetal growth, leading to the fusion of adjacent metacarpal bones. Genetic factors may also play a role in the development of this condition.

Diagnosis

Metacarpal synostosis is typically diagnosed through physical examination and imaging studies such as X-rays. These tests can help identify the extent of fusion and guide treatment decisions.

Treatment

Treatment for metacarpal synostosis depends on the severity of symptoms and functional limitations. In some cases, conservative management such as physical therapy and splinting may be sufficient to improve hand function. Surgical intervention may be considered for more severe cases to separate the fused metacarpal bones and restore hand mobility.

Prognosis

The prognosis for individuals with metacarpal synostosis varies depending on the extent of fusion and the effectiveness of treatment. With appropriate management, many individuals can achieve improved hand function and quality of life.
