Spondylolysis was found in 25 of 46 spines of Eskimos from Greenland, at L1 in one case, at L3 in five cases and at L4 and L5 in 14 cases each. Two spondylolytic vertebrae were seen in the same spine in nine cases. Among young individuals, spondylolysis was found in 2 out of 15 spines and in older in 23 out of 31. The prevalence of spondylolysis was higher, the fourth vertebra was more commonly affected, and spondylolysis occurred at an older age in Eskimos than in other ethnic groups.
在来自格陵兰岛的46名爱斯基摩人的脊柱中，有25例发现椎弓根峡部裂，其中1例位于L1，5例位于L3，L4和L5各有14例。9例在同一脊柱中发现两个椎弓根峡部裂椎体。在年轻个体中，15例脊柱中有2例发现椎弓根峡部裂，在年长个体中，31例中有23例发现椎弓根峡部裂。爱斯基摩人椎弓根峡部裂的患病率更高，第四腰椎更常受累，且椎弓根峡部裂发生的年龄比其他种族更大。
