Significant relationships are highlighted in bold type; tend: tenderness; SLAC: scapholunate advanced collapse; STT: scaphotrapeziotrapezoidal; CMC: 1st carpometacarpal. Results expressed as P value (chi-square) for radial wrist pain and swelling. Tend: tenderness over that area of the wrist on physical examination and documented as a continuous variable (0–10). Results expressed as P value (95% lower; 95% upper).
