Abstract
OBJECTIVE
To investigate the long-term risk of carpal tunnel syndrome (CTS) in people with spinal cord injury (SCI).
DESIGN
Retrospective cohort study.
SETTING
Taiwan's Longitudinal Health Insurance Database 2005, containing data about 1 million people randomly sampled from among those registered in the National Health Insurance Program as of 2005.
PARTICIPANTS
The SCI group consisted of 1681 subjects with SCI, and the comparison group comprised 6724 propensity score-matched subjects without SCI (N=8405). The variables included in propensity-score matching were age, sex, comorbid conditions, and socioeconomic status.
INTERVENTIONS
Not applicable.
MAIN OUTCOME MEASURES
The occurrence of newly diagnosed CTS, defined by at least 1 hospital discharge or 2 outpatient visits with a diagnosis of CTS.
RESULTS
The incidence density of CTS in the SCI group was 7.55 per 1000 person-years (95% confidence interval [CI], 6.03-9.33), and in the comparison group, 4.61 per 1000 person-years (95% CI, 4.08-5.19). The hazard ratio (HR) of CTS for the SCI group was therefore 1.59 (95% CI, 1.24-2.03). Additionally, the HR of CTS for the cervical-SCI subgroup, 1.90 (95% CI, 1.21-2.97) was considerably higher than that of its noncervical counterpart, 1.47 (95% CI, 1.09-1.98).
CONCLUSIONS
People with both cervical and noncervical SCI have an increased risk of developing CTS, as compared with those without SCI. Moreover, the CTS risk appears to be higher for individuals with cervical SCI than their noncervical SCI counterparts.
