بررسی ارتباط ابعاد مچ دست با خطر ابتلا به سندرم تونل کارپ

ABSTRACT Carpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome. It affects women more than men. CTS occurs primarily idiopathically or secondary to other diseases. A square wrist dimension is a risk factor for the development of CTS. This study is done for the evaluation of the relationship between the wrist ratio and CTS. 60 patients (54 females and 6 males) with idiopathic CTS were chosen as the patient group, The wrist thickness (A-P measurment) to width (M-L measurement) ratio was determined. 60 healthy persons with similar age, sex and occupation were selected as the control group. The mean wrist ratio in the patient group was 0.734 and in the control group was 0.674 (P value < 0.001). 95% of the patients with CTS had wrist ratio between 0.72 - 0.78. As the wrist ratio approached 0.72, CTS was much more common. Statistical analysis showed that wrist ratio of 0.72 is the point beyond that, and the risk of CTS strongly increases. At the end, determination of wrist ratio before employment, especially in women whose jobs require repeated wrist and hand activities is suggested.
