English: Coronal illustrations of the wrist depicting the progressive osteoarthritic changes of SLAC arthropathy. a Normal wrist demonstrating an intact scapholunate ligament (white arrowhead), normal scapholunate interval and preservation of the joint spaces. (S scaphoid, L lunate, C capitate, R radius, U ulna). b Stage I: Early findings of SLAC arthropathy including scapholunate ligament tear (black arrowhead) with mild widening of the scapholunate interval, as well as early osteoarthritic changes involving the most radial portion of the radioscaphoid joint (black arrow). c Stage II: Progression of SLAC arthropathy with worsening osteoarthritic changes which now involve the entire radioscaphoid articulation (black arrows), and there has been increased widening of the scapholunate interval. d Stage III: Further progression of SLAC arthropathy depicted by worsening radioscaphoid joint osteoarthritic changes (black arrows), and there is now narrowing of the capitolunate joint space with associated osteoarthritic changes (white arrow). This will eventually progress to further proximal migration of the capitate
