NC54.43/S63.3 Traumatic rupture of lunotriquetral ligament



Traumatic rupture of lunotriquetral ligament is caused by a direct blow to the wrist or by a fall onto an outstretched hand.


Diagnosis is based on physical examination, medical history and imaging studies. Physical examination may reveal swelling, tenderness, pain and instability of the wrist joint. Imaging studies such as X-ray, CT scan, MRI or ultrasound can also be used to confirm the diagnosis.

Differential diagnosis

Differential diagnosis includes other injuries to the wrist such as scapholunate ligament tear, triangular fibrocartilage complex tear, and ligament injuries.


Treatment for traumatic rupture of lunotriquetral ligament includes rest, immobilization with a splint or cast and physical therapy. Surgery may be necessary in some cases.


Prognosis is generally good with non-surgical treatment, but may require surgery in more severe cases. With proper treatment, most patients can return to their normal activities within a few months.
