One hundred and eighty five consecutive patients with carpal
tunnel syndrome (CTS) seen at Jordan University Hospital (JUH)
over an 18-month-period were studied retrospectively. Mean
age=45 years (range 19-80); 156 females, 29 males. The most
common predisposing factors were stressful manual work, followed
by diabetes mellitus and obesity (body mass index, BMI>29). The
most frequent symptoms were nocturnal hand paresthesiae. The
respective sensitivities of Tinel and Phalen signs were 61 and
46%. The diagnostic yield of nerve conduction studies (NCS) was
80% and the most sensitive NCS technique was the median
palm-to-wrist (PW) technique with a yield of 61%. Seventy
percent of the hands with electrophysiological CTS were moderate
and severe. One hundred and forty patients received conservative
treatment and 45 underwent surgical decompression.
