Risk factors for median mononeuropathy of the wrist in postpoliomyelitis patients.
There is evidence that chronic cane, crutch, and wheelchair users are at increased risk for developing pain and functional compromise of the wrist and hand. This investigation examined the prevalence and risk factors for median mononeuropathy at the wrist in the postpoliomyelitis population. The medical records of 148 consecutive patients with histories of poliomyelitis were reviewed. Forty-nine percent of this cohort had complaints of wrist pain. The prevalence rate of carpal tunnel syndrome was 22% (n = 33). Age, sex, duration of disability, and work history did not significantly influence the relative risk of developing this disorder. However, the relative risk of developing this compression neuropathy at the wrist by using the combination of a cane and/or a crutch and a wheelchair was 4.86 (95% confidence interval 2.35-10.06). The high risk associated with chronic cane, crutch, and wheelchair use shows the need for developing preventive strategies.
