Epidemiological changes in traumatic spinal cord injuries for the last 30 years (1990–2019) in South Korea

Subjects

Abstract

Study design

Retrospective descriptive study.

Objectives

To identify the characteristics of and epidemiological trends in traumatic spinal cord injuries (TSCIs) in Korea from 1990 to 2019.

Setting

National Rehabilitation Center affiliated with the Ministry of Health and Welfare in Korea.

Methods

The medical records of 3395 individuals with TSCIs were retrospectively reviewed. Three groups were formed based on onset period (1990–1999, 2000–2009, and 2010–2019) and six groups based on age (≤15, 16–30, 31–45, 46–60, 61–75, and ≥76 years). Pearson’s chi-square and analysis of variance tests were used for statistical analysis.

Results

From 1990 to 2019, the mean age (standard deviation, [SD]) at the time of injury increased from 32.4 (SD = 12.4) years in the 1990s to 47.1 (SD = 16.2) years in the 2010s (F = 222.317 p = <0.001). Land transport and falls were the most common causes of TSCIs. The number of injuries from land transport gradually decreased, while that from falls increased (24.9% in 1990s to 46.3% in 2010s [χ2 = 134.415 p < 0.001]). In the >60 years group, falls were the most common cause of injury, which resulted in 42.9% TSCIs in the 1990s to 59.1% in the 2010s (χ2 = 10.398, p > 0.05). Tetraplegia (n = 769, 58.6%) was more common than paraplegia; incomplete tetraplegia (entire population: =564, 43%; >60 years group: n = 186, 43%) was the highest in the 2010s.

Conclusions

Falls have been the most common cause of TSCIs after 2010s. Implementing national education and campaigns for preventing falls is important to reduce/prevent TSCIs caused by falls in the aged population.
