Brachymetacarpia

Brachymetacarpie D3 8W - CR ap - 001

Brachymetacarpia is a medical condition characterized by the abnormal shortening of the metacarpal bones, which are the bones in the hand that connect the carpal bones of the wrist to the proximal phalanges of the fingers. This condition can affect one or more of the metacarpal bones, leading to a noticeable difference in hand appearance and potentially impacting hand function.

Causes

Brachymetacarpia can be congenital, meaning a person is born with the condition, or it can develop as a result of other medical conditions or injuries. Congenital brachymetacarpia often occurs as an isolated anomaly but can also be part of a syndrome, such as Turner Syndrome or Pseudohypoparathyroidism. Acquired brachymetacarpia may result from traumatic injuries, infections, or other diseases that affect bone growth or health.

Symptoms

The primary symptom of brachymetacarpia is the shortening of one or more of the metacarpal bones, which can lead to a shortened appearance of the affected finger(s). This may also result in reduced hand function, difficulty with certain grasping or pinching tasks, and potential cosmetic concerns. In some cases, individuals may experience no functional limitations, and the condition is identified incidentally.

Diagnosis

Diagnosis of brachymetacarpia typically involves a physical examination and imaging studies. X-rays are commonly used to assess the length and structure of the metacarpal bones and to identify any associated abnormalities. In cases where a genetic syndrome is suspected, genetic testing may be recommended.

Treatment

Treatment for brachymetacarpia varies depending on the severity of the condition and the presence of any associated symptoms or functional impairments. In mild cases, no treatment may be necessary. For individuals experiencing functional limitations or significant cosmetic concerns, surgical intervention may be considered. Surgical options include bone lengthening procedures or the use of bone grafts to extend the length of the affected metacarpal bone(s). Physical therapy may also be recommended to improve hand function and strength.

Prognosis

The prognosis for individuals with brachymetacarpia largely depends on the severity of the condition and the success of any treatment undertaken. Many people with brachymetacarpia lead normal, active lives with minimal impact on daily activities. Surgical interventions can often improve hand function and appearance, although, as with any surgery, there are risks of complications.
