Abstract
The study presents a retrospective analysis of distal radius, proximal femur, vertebral, and sacral fractures that occurred in 938 Hamann-Todd Collection skeletons. Individuals included in the investigation were retrieved from dissecting room cadavers in Cleveland, Ohio, between the years 1910 and 1940. Demographic analysis showed that the mean ages at death for blacks and whites included in the study were 41.9 and 53.8 years, respectively. Evaluations of fracture repair status were made for all fractures that were identified. Observations that document side of involvement and unilateral/bilateral distribution were made for distal radius and hip fractures. It was found that the age-, sex-, and race-related fracture patterns which characterize the early 20th century Hamann-Todd sample strongly correspond in distribution and magnitude to those seen in modern American and European urban industrial communities. The distal radius, hip, vertebral, and sacral fractures which were identified in individuals over 60 years of age appear to be a primary result of skeletal fragility due to age progressive bone loss. However, it is suggested that the early onset and high frequency of distal radius fractures seen in climacteric Caucasian women may be more directly due to accidental falls initiated by a greater frequency, intensity, and duration of vasomotor disturbances which are known to accompanay estrogen withdrawal in perimenopausal white females.
