Erosive osteoarthritis is a term utilized to describe a specific inflammatory condition of the interphalangeal and first carpal metacarpal joints of the hands. The term has become a part of medical philosophical semantics and paradigms, but the issue…
Spondyloarthropathy is a painful arthritic affliction of humans that also occurs in wild mammals. Important questions remain concerning the underlying causes of spondyloarthropathy in mammals, particularly regarding whether it is infectious in origin…
Analyses of New World skeletal populations for the presence of erosions an other osseous alterations and their character, distribution, and radiologic appearance shows that osteoarthritis is predominantly a disease of animals raised in artificially…
Characterization of the nature and skeletal distribution of gout was accomplished in a Chamoru (Chamorros) population with predilection to the disease. Uniform excavation by the gouty diathesis produces a punched-out appearance to these predominantly…
Alterations of vertebral endplates have long been a subject of interest, but are of unclear clinical significance. The vertebral columns of a cohort-based sample of 850 individuals were therefore evaluated for vertebral endplate defects, noting…
The purpose of this study was to assess birds as a potential model for osteoarthritis. Compromised by confounding factors, it has not been possible to clearly delineate causation in humans. Nonhuman mammals manifest osteoarthritis in the natural…
Paravertebral osseous masses in reptiles have been attributed to Paget's disease on the basis of histology. Histologically recognized mosaic architecture and cement lines, however, lack specificity. A Varanus dorianus with this condition was…
Diagnosis of diseases of bone, without benefit of soft tissue, in vivo observation, or blood component analysis requires the development of new criteria for diagnosis. Analyzing chimpanzee skeletal populations, applying such criteria (e.g., lesion…
As the study of bone disease in recent and fossil amphibians and reptiles has evolved from observational speculation to analysis of testable hypotheses, so too has recognition of its contribution to our understanding of diseases and organisms. Given…
Objectives: This study was performed to complement studies on spondyloarthropathy in rhesus macaques by quantifying and characterizing another major form of arthritis and contrasting it with osteoarthritis. Methods: Skeletons of 269 macaques of known…
Assigning responsibility for the origins of treponemal disease has been complicated because of the (diagnostic) impreciseness of the historical written record and the inability to microbiologically distinguish among the treponematoses. Bedouin…
Sixty skeletons of Callithrix jacchus were examined to identify spondy-loarthropathy. Erosive disease in Callithrix was confirmed as spondy-loarthropathy on the basis of diagnostic sacroiliac erosions, syndesmophyte formation, and the nature and…
Shared characteristics and concurrent occurrence of rheumatoid arthritis (RA) and spondyloarthropathy in contemporary populations have compromised development of clear diagnostic criteria for distinguishing them. Although modern populations contain…
Spondyloarthropathy was observed in 25 (2.8%) of 895 preserved canid museum specimens and was catalogued by species. The associated skeletal alterations in canids are indistinguishable grossly and physiologically from those in humans with…
The etiology of arthritis in Hyaenidae has been a subject of conjecture. While osteoarthritis has been considered, the observation of an erosive arthritis prompted a systematic survey of museum specimens to define its nature and frequency.…
Noting the common occurrence of arthritis in contemporary elephants, a skeletal study was undertaken to assess the frequency and nature of the affliction. Spondyloarthropathy was unequivocally diagnosed in mammoths (Mammuthus primigenius) and…
Study Design. A descriptive study of the association between sacroiliac joint (extra-articular) bridging and other enthesopathies. Objectives. To examine the relationship between sacroiliac joint bridging with other entheseal reaction sites in the…
