    Area of Science:

    • Orthopedics
    • Anthropology
    • Radiology

    Background:

    • Spondylolysis is a common stress fracture of the pars interarticularis.
    • Ethnic and geographic variations in spondylolysis prevalence are documented.
    • Previous research suggests higher rates in certain populations.

    Purpose of the Study:

    • To investigate the prevalence and characteristics of spondylolysis in a Greenlandic Eskimo population.
    • To compare spondylolysis rates in Greenlandic Eskimos with other ethnic groups.

    Main Methods:

    • Retrospective analysis of spinal radiographs from 46 Greenlandic Eskimos.
    • Documentation of spondylolysis location and number of affected vertebrae.
    • Age-stratified analysis of prevalence.

    Main Results:

    • Spondylolysis was identified in 25 of 46 spines (54.3%).
    • Prevalence was significantly higher in older individuals (23/31) compared to younger ones (2/15).
    • L4 and L5 were the most commonly affected levels, and 9 individuals had bilateral spondylolysis.

    Conclusions:

    • Greenlandic Eskimos exhibit a high prevalence of spondylolysis, with a notable predilection for the L4 vertebra.
    • Spondylolysis in this population appears to develop or manifest more frequently with age compared to other groups.
