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.
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.
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).
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.
肩袖撕裂是导致肩部功能障碍和疼痛的常见原因。尽管手术治疗的效果会受到多种因素的影响，但仍可获得良好的治疗效果。我们旨在研究利手对肩袖修复术后主观功能结局的影响。
确定在一个日历年中接受肩袖修复的所有患者，并在术后3年进行随访。患者同意纳入本研究，并收集人口统计学数据、利手情况和功能结局数据。使用L'insalata肩部问卷收集结局数据。在适当情况下，使用SPSS 22版进行统计分析。
本研究共纳入144例患者。优势侧组的平均年龄为63±10.1岁，非优势侧组为62±8.6岁。92例患者接受了优势侧手术，52例接受了非优势侧手术。优势手与手术侧之间存在统计学显著相关性（P = 0.005）。优势侧手术组的平均总体结局评分略高，平均为89.8±14.2，而非优势侧组的平均评分为87.4±17.5。多变量线性回归分析显示这种差异无统计学意义（p = 0.4）。
优势侧和非优势侧手术的肩袖修复功能结局未发现差异。该信息将有助于为担心肩袖修复对其优势手功能潜在影响的患者提供咨询。
