Capitate fracture is a break of the capitate bone in the wrist. Symptoms typically include pain and swelling of the wrist.[1] Often there are other wrist bone fractures or joint dislocations.[1] Complications may include arthritis and avascular necrosis.[1]

Typically they occur as a result of a fall on an outstretched hand or a direct blow to the back of the wrist.[1][2] Types include transverse body (most common), transverse pole, verticofrontal, and parasagittal.[1] Diagnosis is usually by X-rays.[1]

For fractures that are well aligned, treatment may be with orthopedic casting, specifically a thumb spica.[1][2] Otherwise surgery is generally required.[1] Failure to heal is not uncommon.[1] Capitate fractures represent about 1 to 2% of breaks of bones within the wrist.[1]

Diagnosis

Diagnosis is often by a posterior anterior wrist X-ray.[2]
