Introduction:
We estimated the lifetime prevalence and incidence of carpal tunnel release (CTR) and identified risk factors for CTR.
Methods:
The study population consisted of individuals aged ≥30 years living in Finland during 2000-2001 (N = 6,256) and was linked to the Finnish Hospital Discharge Register from 2000 to 2011.
Results:
Lifetime prevalence of CTR was 3.1%, and incidence rate was 1.73 per 1,000 person-years. Female sex (adjusted hazard ratio [HR] = 1.8, 95% confidence interval [CI] 1.2-2.8), age of 40-49 years (HR = 2.5, CI 1.7-3.8 compared with other age groups), education (HR = 0.6, CI 0.4-0.9 for high level vs. low/medium level), obesity (HR = 1.7, CI 1.2-2.5 for body mass index ≥30 vs. < 30 kg/m2 ), and hand osteoarthritis (HR = 2.4, CI 1.4-3.9) were associated with incidence of CTR.
Discussion:
CTR is a common surgical procedure, performed on 1.9% of men and 4.1% of women during their lifetimes. Obesity and hand osteoarthritis are associated with an increased risk of CTR. Muscle Nerve 58: 497-502, 2018.
