Abstract

Study design: Retrospective cohort study.

Objective: To describe the characteristics of patients with work-related traumatic spinal cord injuries (TSCI) in Chile.

Setting: Hospital del Trabajador in Santiago, Santiago, Chile.

Methods: Patients suffering from TSCI incurred at the workplace from 1986 to 2005 were identified through records of the Asociación Chilena de Seguridad (ACHS, Chilean Safety Association).

Results: The medical records of 173 patients, 172 men and 1 woman, were analyzed. The yearly average incidence was 7.8 per million workers. Age at TSCI onset was 38.2 ± 12.1 years. The principal external causes for TSCI incurred at the workplace were falls from a height in 86 cases (49.7%) and trauma blows to the vertebral spine in 61 cases (35.3 %). More falls occurred in the field construction, and other traumas occurred as a result of traumatic blows caused by tree trunks and stones in forestry and mining sectors. Mortality in this series was 8.7%, and the worst prognosis was for older patients with complete tetraplegia. The paraplegia:tetraplegia ratio was 3.2:1.

Conclusions: The characteristics of workplace TSCI are specific to this population. It is important therefore to develop prevention programs for specific work-related TSCI.
