Rheumatic hand's clinical, functional and imagiological correlations following metacarpophalangeal joint silicone arthroplasty. Rev Bras Ortop. 2018;53(2):208–212.2255-4971http://hdl.handle.net/10400.16/2328Objective: Evaluation of rheumatoid hand-associated metacarpophalangeal joint silicone arthroplasty most often relies on functional scores alone. This study aimed to understand the correlation between perceived and observed function, strength, and alignment. Methods: Cross-sectional study including all 11 women (15 hands) submitted to second to fifth metacarpophalangeal joint arthroplasty due to rheumatoid arthritis involvement for a time period of seven years. Measurements relied on the Michigan Hand Outcomes Questionnaire, Lafayette Purdue Pegboard, pinch and grip strength, and analysis of a lateral "OK-sign" X-ray view. Correlation analysis used Spearman's coefficient, assuming statistical significance for p-values < 0.05. Results: Objective function was strongly correlated with all other variables (p < 0.05), while perceived function failed to correlate with articular alignment in both measurements (p = 0.240 and p = 0.354). Strength and alignment were also strongly correlated (p < 0.05). Conclusions: Most measurements strongly correlate with each other, with emphasis on objective dexterity measurement.engArthritisRheumatoidArthroplastyHand strengthMetacarpophalangeal jointSiliconesjournal article10.1016/j.rboe.2017.03.012
