Carpal tunnel syndrome in postmenopausal women

OBJECTIVE: Hormonal changes that accompany menopause have a significant impact on the nervous and other physiological systems. Our objective was to evaluate the relationship between carpal tunnel syndrome (CTS) and the clinical features of menopause in postmenopausal women, in comparison to age-matched healthy controls. METHODS: Overall, 6230 women were seen during the study period. Of these, 5587 were not eligible because they were premenopausal or perimenopausal. 537 women did not meet the criteria used in the study for a diagnosis of idiopathic CTS and were excluded. Finally, one hundred and six patients with CTS and 115 controls were examined. The presence of CTS was confirmed both clinically and electrophysiologically. Socio-demographic variables and reproductive histories were evaluated via a structured interview. RESULTS: In comparison to healthy controls, patients with CTS showed a significantly greater number of pregnancies and an earlier age at menopause. Regarding the type of menopause, patients and controls showed similar frequencies for natural versus surgical menopause. The frequency of natural menopause was significantly higher than that of surgical menopause in both groups. CONCLUSION: Our results suggest that age at menopause may be a significant factor in the development of CTS. Pregnancy-related hormonal changes may have long-term effects that increase the incidence of CTS in postmenopausal women.
