Abstract

The aim of this study was to investigate the incidence rates and operations for carpal tunnel syndrome and ulnar and radial neuropathies in specialist care in Finland. Patients diagnosed with entrapment neuropathies of the upper extremity were identified from the Care Register for Health Care, 2007-2016. There were 81,911 cases in 54,095,070 person-years. The total crude incidence rates per 100,000 person-years among women and men were 197 and 105 for carpal tunnel syndrome, 26 and 36 for ulnar neuropathies, and 5.7 and 8.5 for radial neuropathies, respectively. Of these, carpal tunnel syndrome was operated on in 63% of women and 61% of men, ulnar neuropathy in 43% of women and 47% of men, and radial neuropathy in 11% of women and 8% of men. Incidence of carpal tunnel syndrome and ulnar neuropathies increased up to late middle age, while radial neuropathies were less common. Level of evidence: III.
