Standard wrist radiographs are normal. scaphoid is flexed and lunate is extended as scapholunate ligament no longer restrains this articulation, lunate extended > 10 degrees past neutral, resultant scaphoid flexion and lunate extension creates, abnormal distribution of forces across midcarpal and radiocarpal joints, malalignment of concentric joint surfaces, describes predictable progression of degenerative changes from the radial styloid to the entire scaphoid facet and finally to the unstable capitolunate joint, as the capitate subluxates dorsally on the lunate, key finding is that the radiolunate joint is spared, unlike other forms of wrist arthritis, since there remains a concentric articulation between the lunate and the spheroid lunate fossa of the distal radius, Arthritis between scaphoid and radial styloid, Arthritis between scaphoid and entire scaphoid facet of the radius, While original Watson classification describes preservation of radiolunate joint in all stages of SLAC wrist, subsequent description by other surgeons of "stage IV" pancarpal arthritis observed in rare cases where radiolunate joint is affected, validity of "stage IV" changes in SLAC wrist remains controversial and presence pancarpal arthritis should alert the clinician of a different etiology of wrist arthritis, patients localize pain in region of scapholunate interval, tenderness directly over scapholunate ligament dorsally, will not be positive in more advanced cases as arthritic changes stabilize the scaphoid, with firm pressure over the palmar tuberosity of the scaphoid, wrist is moved from ulnar to radial deviation, positive test seen in patients with scapholunate ligament injury or patients with ligamentous laxity, where the scaphoid is no longer constrained proximally and subluxates out of the scaphoid fossa resulting in pain, when pressure removed from the scaphoid, the scaphoid relocates back into the scaphoid fossa, and typical snapping or clicking occurs, obtain standard PA and lateral radiographs, PA radiograph will reveal greater than 3mm diastasis between the scaphoid and lunate, PA radiograph shows sclerosis and joint space narrowing between scaphoid and the entire scaphoid fossa of distal radius, 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, thinning of articular surfaces of the proximal scaphoid, scaphoid facet of distal radius and capitatolunate joint with synovitis in radiocarpal and midcarpal joints, NSAIDs, wrist splinting, and possible corticosteroid injections, prevents impingement between proximal scaphoid and radial styloid, may be performed open or arthroscopically via 1,2 portal for instrumentation, since posterior and anterior interosseous nerve only provide proprioception and sensation to wrist capsule at their most distal branches, they can be safely dennervated to provide pain relief, can be used in combination with below procedures for Stage II or III, contraindicated with caputolunate arthritis (Stage III SLAC) because capitate articulates with lunate fossa of the distal radius, contraindicated if there is an incompetent radioscaphocapitate ligament, excising entire proximal row of carpal bones (scaphoid, lunate and triquetrum) while preserving, provides relative preservation of strength and motion, also provides relative preservation of strength and motion, wrist motion occurs through the preserved articulation between lunate and distal radius (lunate fossa), similar long term clinical results between scaphoid excision/ four corner fusion and proximal row carpectomy, wrist fusion gives best pain relief and good grip strength at the cost of wrist motion, - Scaphoid Lunate Advanced Collapse (SLAC), Lunate Dislocation (Perilunate dissociation), Gymnast's Wrist (Distal Radial Physeal Stress Syndrome), Scaphoid Nonunion Advanced Collapse (SNAC), Carpal Instability Nondissociative (CIND), Constrictive Ring Syndrome (Streeter's Dysplasia), Thromboangiitis Obliterans (Buerger's disease).
