One burial ground containing 47 skeletons was used by the Ipiutak at about the start of the Christian era. The other burial ground was used by the Tigara a thousand years later and contained 248 skeletons. The lesion is a separation of the vertebral arch from the vertebral body. It usually involves the fifth lumbar vertebra but may involve others and more than one. The present incidence in the United States is about 7%. Among the Tigara the incidence was 45% and more than twice that of the Ipiutak, 21%. The youngest case was in a child of five and the deformity was uncommon before adult life. The incidence and extent of the lesion increased with age suggesting an hereditary weakness as an etiological factor. No other etiological factor could be determined although several were considered. The clinical disability could not be determined but it seemed to have no effect on longevity.<\/jats:p>","DOI":"10.1002\/ajpa.1330280113","type":"journal-article","created":{"date-parts":[[2005,8,9]],"date-time":"2005-08-09T08:25:53Z","timestamp":1123575953000},"page":"43-47","source":"Crossref","is-referenced-by-count":41,"title":["Vertebral arch defects in the lumbar vertebrae of pre\u2010historic American Eskimos.
