A wrist sprain is a common injury for all sorts of athletes, as well as older people. As you slip, you automatically put out your hand out to break your fall. Once your hand hits the ground, the force of impact bends it back toward your forearm and, as a result, a tear or a complete break to the ligament occurs.
Scapholunate ligament – (SL)
Damage to this ligament usually occurs due to an injury after a fall on the outstretched hand and abducted wrist. As a result there is swelling and pain along the back of the wrist. Tenderness is the most perceptible between the scaphoid and lunate bone. In recognition of SL, the most important is the clinical evaluation and additional ultrasound and MRI tests. During the Watson test pain increases and a “click” sound is observed. Damage can be seen on an x-ray. Magnetic resonance imaging and ultrasound mainly show a complete ligament rupture.
Surgical treatment consists of arthroscopic surgery, the sewing or ligament reconstruction. In chronic lesions, ligament reconstruction is necessary.
Lunotriquetra Ligament (LT)
Damage to this ligament usually occurs due to an injury after a fall on the outstretched hand of the upright and inclined radial wrist. Pain occurs on the ulnar side of the wrist and the limb weakness. Tenderness is the most perceptible between the scaphoid bone and lunotriquetra. The diagnosis in most cases is based on the clinical examination. An X-ray, ultrasound and MRI do not always confirm the damage.
If there is absence of complete ligament rupture, treatment is based on conservative treatment and placing the wrist out of motion. The patient returns to physical activity after a few weeks. The surgical procedure is performed in case of the lack of conservative treatment affects. A return to sport activity is possible after several months of treatment.
