Purpose: To describe the demographics, neurophysiological grading, and incidence of patients undergoing carpal tunnel decompression (CTD) for carpal tunnel syndrome (CTS) in a single region., Methods: A retrospective review of 2,313 patients aged greater than 16 years who underwent 3,073 CTDs between January 2000 and August 2010. Crude annual and age- and sex-specific incidences were calculated for the study period. Nerve conduction study grades were recorded and compared with age and sex., Results: Of the 2,313 patients 1,419 (61%) were female and 890 (39%) were male. Mean age at surgery was 56 years (range, 16-93 years). Females had a significantly higher CTD incidence compared with males (161 vs 108/100,000 person-years, respectively). The highest rates of CTD were seen in the 70- to 79-year age group for both men and women (307/100,000 person-years). Neurophysiological grade increased in severity with increasing age despite using an age-adjusted grading system, with higher grades in patients aged greater than 65 years., Conclusions: This study suggests that carpal tunnel syndrome has the highest incidence in older people who tend to have more severe neurophysiological changes., Type of Study/level of Evidence: Prognostic II., (Copyright © 2015 American Society for Surgery of the Hand.

We present a case in which the radial artery was found running within the carpal tunnel at the time of routine carpal tunnel decompression. It appears to be an anomalous superficial palmar branch of the radial artery that is substituting for the normal radial artery.

Purpose: To determine the outcomes of carpal tunnel decompression in elderly patients and whether outcomes can be predicted by the severity of presurgical nerve conduction study results., Methods: We performed a retrospective study of all patients over 70 years of age who had elective carpal tunnel release at Dunedin Hospital between April 1999 and April 2002 with a minimum of 1-year follow-up evaluation. A grading system for presurgical nerve conduction studies was formulated that scored patients from 1 to 6 according to severity. Patients were evaluated by a mailed questionnaire (Symptom Severity Score) with follow-up telephone calls to nonresponders., Results: Eighty-three carpal tunnel release procedures performed in 70 patients were included in the study. Eighty percent had marked to severe neurophysiologic changes (grades 4-6). The median postsurgical Symptom Severity Score was 1.3 (inter-quartile range, 1.1-1.7). Patients expressed satisfaction with the outcome of the surgery in 78 of 83 cases (94%). There was a significant relationship between presurgical nerve conduction grade and postsurgical Symptom Severity Score., Conclusions: This study shows that elderly patients have low postsurgical symptom scores and express high levels of satisfaction after surgery for carpal tunnel syndrome. There was a significant relationship between severity of neurophysiologic abnormalities and a higher Symptom Severity Score after surgery. Severe abnormality, however, should not exclude elderly patients from surgery.
