“…A dorsopathy was defined as a main diagnosis according to the International Classification of Diseases (ICD) version 10 (ICD-10), including radiculopathies (ICD-10: M51.1, M51.1K, M54.1), spondylopathies (ICD-10: M47.8, M47.9, M47.9K, M48.0, M48.0K, M48.8, M48.8K and M48.8W), and other dorsopathies (ICD-10: M54.3, M54.4, M54.5, M53.8 and M53.9) [11]. The surgery codes used to identify patients with LSDS were coded according to the Nordic Medico-Statistical Committee (NOMESCO) codes of surgical procedures: ABC 7, 16, 26, 36, 56, 66, and 99 [12]. To focus on persons that are in the work force, individuals on full- or part-time DP at baseline ( n =1 541) were excluded.…”
