The outcome of wrist surgery: what factors are important and how should they be reported?

ABSTRACT

A prospective longitudinal study was carried out on a cohort of 86 patients who had undergone surgery for diverse wrist conditions. Disabilities of Arm Shoulder and Hand questionnaire, a pain assessment, a wrist functional score, range of movement and grip strength measures were completed. The Mayo Clinic wrist score was also calculated. The World Health Organization International Classification of Function was used as a framework for analysis. The responsiveness of each outcome measure was calculated in terms of distribution- and anchor-based methods. Pain was the most important factor in determining outcome. Changes in objective measures were less important. The responsiveness of the various measures was similar except for the Mayo Clinic wrist score, which was less responsive than the others. Patient-completed measures currently in use are multidimensional. Classifying the content according to the International Classification of Function would clarify the effects of wrist surgery on the different aspects of health.
