Hypertrophic osteoarthropathy in a young adult male from Berber, Sudan (2nd-3rd century CE)

A case of secondary hypertrophic osteoarthropathy from medieval Tuscany (central Italy, 10th-12th centuries CE)

OBJECTIVES

This study aims to provide a detailed evaluation of a case of secondary hypertrophic osteoarthropathy (HOA) and to explore insights into the presence and consequences of disease in medieval rural Italy.

MATERIALS

The skeleton of a male (US 4405) with an estimated age at death of 51-69 years excavated from the medieval rural site of Pieve di Pava (Siena, Italy).

METHODS

Macroscopic and radiological (x-ray, CT) analyses were performed.

RESULTS

Symmetrical extensive periosteal new bone formation on the diaphyseal and metaphyseal regions of this individual's long bones; the lower limbs were more extensively and severely affected than the upper limbs and the distal segments were more severely altered in comparison to the proximal ones.

CONCLUSIONS

The macroscopic and radiological features are highly consistent with a diagnosis of secondary HOA.

SIGNIFICANCE

The excellent state of preservation allowed the evaluation of rarely noted skeletal manifestations of HOA and provided insight into aspects of rural life in medieval Italy.

LIMITATIONS

Molecular analysis was not successful in sequencing the aDNA of tuberculosis, therefore the underlying primary cause of secondary HOA, whether pulmonary or extrapulmonary, remains obscure in this case.

SUGGESTION FOR THE FUTURE RESEARCH

It is advisable to regularly revisit the data available from osteoarchaeological collections in order to identify further cases of HOA, along with to further investigate the known cases to search for the underlying primary disease.

Possible Causes of Hypertrophic Osteoarthropathy in the La Ferrassie 1 Neanderthal

For over a century, researchers have been perplexed by the unique osteological findings on La Ferrassie 1 (LF1), one of the most complete Neanderthal remains ever found. In 1997, Fennel and Trinkaus proposed that LF1 suffered from hypertrophic osteoarthropathy (HOA), likely secondary to chronic thoracic infection or pulmonary malignancy. This disease process can have many etiologies, and no study has fully explored the possible origin of LF1's HOA. Ultimately, it is most likely that LF1's HOA etiology arose from one of the many infectious diseases that prehistoric Neanderthals were exposed to, specifically a chronic pulmonary RNA virus.

Co-morbidity with hypertrophic osteoarthropathy: A possible Iron Age Sarmatian case from the Volga steppe of Russia

PURPOSE

Hypertrophic osteoarthropathy (HOA) is a condition that can be inherited or acquired. It causes diffuse periosteal new bone formation on the long bones, with a predilection for the appendicular skeleton. When acquired, it is a nonspecific indicator of systemic disease that arises following a primary condition. This paper reviews the palaeopathological literature associated with this rare condition. It also describes the first possible case of co-morbidity associated with hypertrophic osteoarthropathy in an adult skeleton (cal. BC 170 - 1 cal. AD) from the mobile pastoralist Sarmatian culture of the Volga steppes of Russia.

METHODS

Macroscopic and radiological examination provide differential diagnoses of the lesions, while clinical and bioarchaeological analyses offer insights into the possible experience of disease and social implications of care among the nomadic populations of Iron Age Russia.

RESULTS

The analysis of Sk. 6524.102 displays lesions that may be due to both hypertrophic osteoarthropathy and osteomalacia. The man was physically impaired and his participation in physically challenging activities would have been limited.

CONCLUSIONS

The study stresses that co-morbidity is a key parameter when interpreting disease in past populations, particularly when the diagnosis involves hypertrophic osteoarthropathy.

SIGNIFICANCE

This is the first case of hypertrophic osteoarthropathy identified in Eurasian prehistoric populations. The research emphasises the significance of co-morbidity in the past.

LIMITATIONS

The diagnosis of co-morbid diseases in human remains is extremely complex and the conditions were identified as most probable by a process of elimination.

SUGGESTIONS FOR FURTHER RESEARCH

Further studies should be dedicated to understanding co-morbidity in the past.

Secondary hypertrophic osteoarthropathy in a male from the Early Medieval settlement of Lauchheim, Germany

Hypertrophic osteoarthropathy (HOA) is rarely diagnosed in archaeological human skeletons. Here, we report on the well-preserved skeleton of a middle-adult man from the early Medieval settlement site of Lauchheim (Germany) that exhibits pronounced multi-layered shell-like periosteal new bone formation in a bilaterally symmetric fashion on the long bones, the skeletal elements of the pelvis and those of the pectoral girdle. In addition, the two distal phalanges recovered show signs of osteoclastic resorption on their distal tuberosities. The distribution and morphology of the observed lesions are consistent with a diagnosis of HOA. The adult age at death of the individual and the co-occurrence of "healed" and "active" lesions suggest a secondary form of HOA. Given that only skeletal remains were available for study, the underlying (pulmonary or non-pulmonary) primary disease cannot be definitively ascertained in the present case. No osseous changes were found on the ribs, but signs of osteoclastic resorption were observed on the dorsal surface of the sternal body, which might indicate a retrosternal or mediastinal location of the primary disease. Thus far, only a few archaeological case studies of secondary HOA reported signs of the presumed underlying primary disease, which was of a pulmonary nature in each of the individuals.
