Outcome of carpal tunnel decompression: the influence of age, gender, and occupation.

The aim of this study was to investigate the effect of age, gender, and occupation on the outcome of carpal tunnel decompression. A total of 479 patients (342 females, 137 males) with a mean age of 56 years undergoing 608 carpal tunnel decompressions were prospectively studied. Outcome was assessed using the Brigham Hospital carpal tunnel questionnaire at two weeks pre-operatively and six months post-operatively. Cases were divided into four age categories (less than 40 years of age, 40-59, 60-79, and over 80 years of age) and two occupation (repetitive and non-repetitive) groups. The mean differences for both the symptom-severity and functional-status scores amongst the four age categories were similar and no significant difference was found. The mean differences for both the symptom-severity and functional-status scores between females and males and the two occupation groups were similar and no significant differences were found. The majority of the patient's symptoms improved following carpal tunnel decompression. However, we found no influence of age, gender, or occupation on the outcome of carpal tunnel decompression in our series of patients.
