The scapholunate ligament is located in the wrist and is responsible for connecting the scaphoid and lunate bones. Traumatic rupture of the scapholunate ligament usually occurs as a result of a direct blow to the wrist or due to a fall onto an outstretched hand.
Traumatic rupture of the scapholunate ligament is usually diagnosed using imaging studies such as X-rays or MRI. Physical examination may reveal tenderness, swelling, and reduced range of motion in the wrist.
Differential diagnosis may include other wrist injuries such as scaphoid fracture, triangular fibrocartilage complex (TFCC) tear, or ligament sprains.
Treatment for traumatic rupture of the scapholunate ligament typically includes immobilization with a splint or cast, followed by physical therapy to restore range of motion and strength. Surgery may be recommended in severe cases.
The prognosis for traumatic rupture of the scapholunate ligament typically depends on the severity of the injury and the response to treatment. Most patients can expect to make a full recovery with proper treatment.
