What is Stage 3 SLAC wrist?
What is Stage 3 SLAC wrist?
Stage III SLAC wrist entails sclerosis and joint space narrowing between the lunate and capitate. Eventually, the capitate will migrate proximally into the space created by the scapholunate dissociation.
How do you fix a SLAC wrist?
Asymptomatic (SLAC) wrist generally does not require treatment. Symptomatic mild SLAC is managed nonoperatively, for example, wrist immobilization with splints, nonsteroidal anti-inflammatory drugs, and corticosteroid injections.
What causes SLAC wrist?
CAUSES. Most cases of SLAC wrist start with a significant wrist sprain or fracture, but occasionally no history of injury is recalled. Some cases of scapholunate ligament injury may be due to repetitive heavy loading of the wrist as seen with obesity, or inflammatory conditions of the wrist that damage the ligament.
How common is SLAC wrist?
There are three different patterns of arthropathy seen about the wrist which include SLAC, triscaphe arthritis (between the trapezium, trapezoid and distal scaphoid) and a combination pattern. SLAC wrist is the most common type of wrist arthritis and accounts for approximately 55 % of all wrist arthritis [14].
What are the symptoms of SLAC wrist?
Symptoms of Scapholunate Advanced Collapse (SLAC) Wrist
- Difficulty with weight-bearing across the wrist.
- Significant pain in the area of the scapholunate interval.
- Progressive weakness of the involved hand.
- Wrist stiffness.
- Weak grip strength.
- Tenderness to palpation.
- Reduced range of motion of the wrist.
What causes scapholunate widening?
Scapholunate dissociation most commonly results from trauma. It is the leading cause of SLAC (scapholunate advanced collapse) wrist, which is the most common pattern of degenerative arthritis in the wrist 4.
What is SLAC wrist surgery?
A SLAC reconstruction involves excision of the scaphoid and arthrodesis of the capitate, lunate, hamate, and triquetrum. Two parallel dorsal transverse incisions, a lazy S incision, or a central longitudinal incision over the distal radiocarpal joint and styloid process is made.
What is scapholunate widening?
It results from the relative instability between the scaphoid and lunate bones secondary to the injury of scapholunate ligament and generally presents radiographically as a widened medial-lateral gap between the two carpal bones.
What is scapholunate reconstruction surgery?
Description of Technique Our technique for scapholunate (SL) reconstruction involves ligament reconstruction utilizing a portion of the flexor carpi radialis tendon rerouted via transosseous tunnels across the scaphoid, lunate, and triquetrum (scapholunotriquetral tenodesis).
What happens after wrist ligament surgery?
After surgery the wrist will be immobilized in a plastic cast or splint for several or more weeks. Patients are instructed to keep the wrist elevated to reduce swelling and pain and to improve their ultimate flexibility. Antibiotics and other medications may be prescribed to reduce pain and aid recovery.
What is the recovery time for Scapholunate ligament surgery?
Healing of the Scapholunate Ligament takes approximately 3 months. This procedure is usually performed under general anesthesia which means you will be asleep for the procedure.
How long after wrist surgery can I drive?
Conclusions: Most patients could safely return to driving within 3 weeks of surgery. Pain was the primary limiting factor affecting driving ability. Safe return to driving may be warranted within 3 weeks of distal radius volar plate fixation in some patients.
What does stage III SLAC wrist PA show?
Stage III SLAC wrist PA radiograph shows sclerosis and joint space narrowing between the lunate and capitate, and the capitate will eventually migrate proximally into the space created by the scapholunate dissociation
What are the stages of SLAC wrist osteoarthritis?
Stage III SLAC wrist: Osteoarthritis involving capitolunate articulations and radio scaphoid. Stage IV SLAC wrist: Osteoarthritis involving radio carpal and intercarpal articulations with or without distal radio ulnar joint (DRUJ).
Which is the best treatment for Stage II SLAC?
Stage II SLAC wrist can be successfully treated with this procedure, radioscaphoid arthrodesis, or proximal row carpectomy. Of the three procedures, proximal row carpectomy best preserves wrist mobility, with a flexion-extension arc of 71 degrees.
What does Scapholunate advanced collapse ( SLAC ) mean?
Scapholunate advanced collapse (SLAC) refers to a pattern of wrist malalignment that has been attributed to post-traumatic or spontaneous osteoarthritis of the wrist. It is a complication that can occur with undiagnosed or untreated scapholunate dissociation.
