|Transverse fracture at the mid capitate|
|Symptoms||Wrist pain and swelling|
|Complications||Arthritis, avascular necrosis, failure to heal|
|Types||Transverse body, transverse pole, verticofrontal, parasagittal|
|Causes||Fall on an outstretched hand|
|Treatment||Orthopedic casting, surgery|
|Frequency||1 to 2% of wrist fractures|
Capitate fracture is a break of the capitate bone in the wrist. Symptoms typically include pain and swelling of the wrist. Often there are other wrist bone fractures or joint dislocations. Complications may include arthritis and avascular necrosis.
Typically they occur as a result of a fall on an outstretched hand or a direct blow to the back of the wrist. Types include transverse body (most common), transverse pole, verticofrontal, and parasagittal. Diagnosis is usually by X-rays.
For fractures that are well aligned, treatment may be with orthopedic casting, specifically a thumb spica. Otherwise surgery is generally required. Failure to heal is not uncommon. Capitate fractures represent about 1 to 2% of breaks of bones within the wrist.
Diagnosis is often by a posterior anterior wrist X-ray.
