RT Journal A1 Franzblau A, Werner RA T1 WHat is carpal tunnel syndrome? JF JAMA JO JAMA YR 1999 FD July 14 VO 282 IS 2 SP 186 OP 187 DO 10.1001/jama.282.2.186 UL http://dx.doi.org/10.1001/jama.282.2.186 AB Carpal tunnel syndrome (CTS) is a common diagnosis with an estimated lifetime risk of 10% and an annual incidence of 0.1% among adults.1- 2 These estimates are undoubtedly conservative because they are based on data collected prior to the substantial increase in work-related cases of CTS in the 1980s and early 1990s and the concomitant increased awareness of this condition.3- 4 More recent estimates of the prevalence of CTS in the general population are 0.6% in men and 5.8% in women.5 Now, data from Sweden reported by Atroshi and colleagues6 in this issue of THE JOURNAL suggest an overall prevalence of 2.1%.
