Traumatic rupture of the radiocarpal ligament is caused by a direct blow to the wrist, such as a fall onto an outstretched hand. Other causes may include repetitive stress, such as a sports-related injury or overuse.
Diagnosis of traumatic rupture of the radiocarpal ligament is typically made through a physical examination, x-rays, and sometimes an MRI. On examination, the doctor may note swelling, tenderness, and decreased range of motion. X-rays may show a fracture of the bones in the area, and an MRI may be used to confirm the diagnosis and rule out other possible causes.
Possible differential diagnoses for traumatic rupture of the radiocarpal ligament include carpal tunnel syndrome, De Quervain’s tenosynovitis, trigger finger, and wrist sprains.
Treatment for traumatic rupture of the radiocarpal ligament usually involves rest, splinting or casting, and physical therapy. Surgery may be necessary if the tear is severe or if other treatments do not provide relief.
The prognosis for traumatic rupture of the radiocarpal ligament is generally good. With proper treatment, most patients can make a full recovery and return to their normal activities.
