XR-JSN (A) was scored in 13 locations as per the Genant-modified Sharp method (thin lines: proximal interphalangeal (PIP) joints 1 to 5, metacarpophalangeal (MCP) joints 1 to 5, carpometacarpal (CMC) joints 3 to 5 as a unit, capitate-lunate-scaphoid joints as a unit, and scaphoid-radius and lunate-radius joints as a unit). MRI-JSN (B) was scored in these same 17 joints (thin lines) plus eight additional joints (thick lines: trapezoid-trapezium joint, scaphoid-trapezium joint, scaphoid-trapezoid joint, CMC joint 2, capitate-trapezoid joint, capitate-hamate joint, hamate-triquetrum joint, and triquetrum-lunate joint).
