Abstract
Introduction:Rotator cuff tears are a common cause of shoulder disability and pain. Excellent outcomes can be obtained with surgical treatment although this outcome is affected by several factors. We sought to investigate the effect of hand dominance on subjective functional outcome post rotator cuff repair.Methods:All patients who had rotator cuff repair over a calendar year were identified and followed up at 3 years post operatively. Patients were consented for inclusion in the study and demographic data, hand dominance and functional outcome data was collected. L’insalata shoulder questionnaire was used for outcome data collection. SPSS version 22 was used for statistical analysis where appropriate.Results:144 patients were included in this study. Mean age was 63 +/- 10.1 years in the dominant side group and 62 +/- 8.6 years in the non-dominant group. 92 patients had dominant side surgery and 52 had non-dominant side surgery. There was a statistically significant correlation between dominant hand and operated side (P=0.005). The mean overall outcome score was marginally higher in the dominant surgery group with a mean of 89.8 +/- 14.2 compared with a mean of 87.4 +/- 17.5 in the non-dominant group. Multi-variate linear regression analysis revealed this difference to be non-significant (p = 0.4).Conclusion:No difference was found in the functional outcome of rotator cuff repair between dominant and non-dominant side surgery. This information will help in counselling patients who are concerned about the potential impact of rotator cuff repair on the function of their dominant hand.
Highlights
Rotator cuff tears are a common cause of shoulder disability and pain
It could be assumed that patients who have rotator cuff repair surgery on their dominant side will be more limited in terms of ability to perform their activities of daily living during the immobilisation and recovery period
Hand dominance was significantly associated with side of rotator cuff tear (P=0.005)
Summary
Rotator cuff tears are a common cause of shoulder disability and pain. Excellent outcomes can be obtained with surgical treatment this outcome is affected by several factors. Rotator cuff tears are a common pathology associated with degenerative changes in the shoulder joint They cause significant disability, pain and poor health status [1, 2] and their prevalence is increasing within an aging population [3, 4]. Many studies have documented excellent outcomes following rotator cuff repair surgery [5, 6], complications can occur [7]. It is a costly procedure [8] and an increased role for non-operative treatment has been proposed [9]. We hypothesised that due to differences in expectations and the physical demands placed upon patients’ dominant hand following surgery, functional outcome differences may exist between dominant and nondominant hand patients beyond the initial rehabilitation period
