Osteoporosis, osteomalacia, and hip fracture: A case study from the Terry collection

Rickets, resorption and revolution: An investigation into the relationship between vitamin D deficiency in childhood and osteoporosis in adulthood in an 18th-19th century population

OBJECTIVE

This study employs a Developmental Origins of Health and Disease (DOHaD) approach to assess the effect of vitamin D deficiency (VDD) in childhood on the risk of osteoporosis in adulthood in an archaeological sample of skeletons dating from the 18th to 19th centuries.

MATERIALS

Femora and lumbar vertebrae of 65 adults aged 18+ years (26 diagnosed with residual rickets and 39 without) from an 18th-19th century Quaker burial ground at Coach Lane, North Shields, England.

METHODS

Bone mineral density (BMD) was measured for the femoral neck and first four lumbar vertebrae of each individual using a dual energy X-ray absorptiometry (DXA) scanner as a proxy for assessing osteoporotic fracture risk.

RESULTS

3-way ANOVA revealed no statistically significant differences in BMD between individuals with and without residual rickets across age and sex.

CONCLUSIONS

A combination of lifestyle and environmental factors likely influenced the BMD of people buried at Coach Lane across the life course. The impact of childhood VDD on BMD later in life can be mitigated through other factors such as physical activity and diet.

SIGNIFICANCE

This is one of the first bioarchaeological studies to take a DOHaD approach to understand osteoporosis risk in 18th-19th century England. It highlights the complexity of aetiological factors for osteoporosis and that VDD in early life does not necessarily predispose a person to osteoporosis in adulthood.

LIMITATIONS

BMD is not the only indicator of osteoporosis. Microscopic methods for the assessment of childhood vitamin D deficiency, such as inter-globular dentine analysis, were not applied.

Structural violence and institutionalized individuals: A paleopathological perspective on a continuing issue

Past and present institutions (e.g., state and public hospitals, assisted living facilities, public nursing homes) have struggled with structural issues tied to patient care and neglect, which often manifests in the form of fracture trauma, and may explain why institutionalized individuals are at higher risk for this injury. Six hundred individuals from the Robert J. Terry Anatomical Collection born between 1822-1877 were examined to investigate hip fracture prevalence. Analysis of associated records and documentary data, including death, morgue, and census records, revealed that 36.3% (n = 218) of these individuals died in institutions such as the St. Louis State Hospital, City Infirmary, and Missouri State Hospital No. 4. Of the institutionalized individuals, 4.3% had evidence of hip fracture, significantly higher than the non-institutionalized (2.3%). Records revealed that many hip fractures were suffered around the time of death in state hospitals and were preventable, resulting from structural issues tied to understaffing and underfunding. Forensic and clinical literature, as well as current news media, indicate that structural violence in the forms of underfunding and understaffing continues to manifest as hip fractures harming institutionalized individuals today. This paper demonstrates how an anthropological perspective using paleopathological analysis sheds light on the chronicity and time depth of this issue, with the aim of driving public policy to entrench the equitable care of institutionalized people as a human right.

The madness they endured: A biocultural examination of women's experiences of structural violence within 20th-century Missouri state mental hospitals

OBJECTIVE

This study employs feminist disability theory and the concept of structural violence to interpret the results of skeletal and documentary analysis of fracture and disease presence (i.e., syphilis and tuberculosis) among a group of institutionalized women who lived and died within 20th-century Missouri state mental hospitals.

MATERIALS

The skeletal remains and corresponding death certificates of 52 adult Euro-American women housed in the Robert J. Terry Anatomical Collection at the Smithsonian Museum Support Center. Archival and historical literature concerning state mental hospitals were also utilized.

METHODS

Macroscopic skeletal analysis of fracture and disease combined with archival research (i.e., associated death certificates and historical documentation).

RESULTS

Approximately 15% of patients demonstrated evidence of perimortem hip fractures with no surgical intervention, most of whom were labeled "psychotic". Death certificates revealed the presence of syphilis (n = 4) and death from TB (n = 5).

CONCLUSIONS

Nineteenth and 20th-century patriarchal conditions contributed to the institutionalization of women. Women who were impoverished, spouseless, and perceived as mentally or physically disabled were particularly vulnerable to institutionalization. Once hospitalized, patients were exposed to structurally violent conditions including neglect and abuse that resulted in avoidable harm.

SIGNIFICANCE

Historical and documentary data associated with osteological collections is underutilized and can serve to both humanize these individuals and advance our understanding of their intersectional experiences. The implementation of theoretical frameworks within bioarchaeology can also assist in more holistically interpreting the complexities of past life.

LIMITATIONS

Small, homogenous sample size limited by macroscopic analysis.

FURTHER RESEARCH

Future work should increase sample size, heterogeneity, and conduct other relevant skeletal and documentary analyses.

Metabolic Bone Diseases and New Drug Developments

Metabolic bone diseases are serious health issues worldwide, since several million individuals over the age of 50 are at risk of bone damage and should be worried about their bone health. One in every two women and one in every four men will break a bone during their lifetime due to a metabolic bone disease. Early detection, raising bone health awareness, and maintaining a balanced healthy diet may reduce the risk of skeletal fractures caused by metabolic bone diseases. This review compiles information on the most common metabolic bone diseases (osteoporosis, primary hyperparathyroidism, osteomalacia, and fluorosis disease) seen in the global population, including their symptoms, mechanisms, and causes, as well as discussing their prevention and the development of new drugs for treatment. A large amount of research literature suggests that balanced nutrition and balanced periodic supplementation of calcium, phosphate, and vitamin D can improve re-absorption and the regrowth of bones, and inhibit the formation of skeletal fractures, except in the case of hereditary bone diseases. Meanwhile, new and improved drug formulations, such as raloxifene, teriparatide, sclerostin, denosumab, and abaloparatide, have been successfully developed and administered as treatments for metabolic bone diseases, while others (romososumab and odanacatib) are in various stages of clinical trials.

The Importance of Historical Medical Records Review in the Interpretation of Dry Bone Lesions on Identified Skeletal Remains: A Case Study of a Polymorbid Male (1895-1940)

ABSTRACT

The examination of documented skeletal remains provides an exceptional opportunity for biohistorical research to answer questions about an individual's life and death. Research in this area also makes it possible to assess the reliability of historical records from the period of interest, which is often the subject of discussion, especially in cases of historically known individuals. The remains of K.B.C. (1895-1940), a prominent local landowner and politician, were exhumed because of the repair of a family tomb in Jíloviště, Czech Republic. The aim of this study was to analyze pathological changes in his bones and to interpret these by comparing them with the results of a historical medical records review of private family and public archives regarding his diseases and death, thus verifying their credibility. Morphological and X-ray examinations of the bones revealed several serious pathological changes, whose presence fully corresponded to the studied documents. This showed the records' reliability, and it was thus possible to accurately interpret the lesions found. The results demonstrated the need for interdisciplinary collaboration in the analysis of such cases, including the assistance of the living descendants of the studied individuals, if possible.

Bone loss markers in the earliest Pacific Islanders

Kingdom of Tonga in Polynesia is one of the most obese nations where metabolic conditions, sedentary lifestyles, and poor quality diet are widespread. These factors can lead to poor musculoskeletal health. However, whether metabolic abnormalities such as osteoporosis occurred in archaeological populations of Tonga is unknown. We employed a microscopic investigation of femur samples to establish whether bone loss afflicted humans in this Pacific region approximately 3000 years ago. Histology, laser confocal microscopy, and synchrotron Fourier-transform infrared microspectroscopy were used to measure bone vascular canal densities, bone porosity, and carbonate and phosphate content of bone composition in eight samples extracted from adult Talasiu males and females dated to 2650 BP. Compared to males, samples from females had fewer vascular canals, lower carbonate and phosphate content, and higher bone porosity. Although both sexes showed evidence of trabecularised cortical bone, it was more widespread in females (35.5%) than males (15.8%). Our data suggest experiences of advanced bone resorption, possibly as a result of osteoporosis. This provides first evidence for microscopic bone loss in a sample of archaeological humans from a Pacific population widely afflicted by metabolic conditions today.
