Diagnostic criteria for developmental dislocation of the hip in human skeletal remains

Dislocation is the most severe form of developmental dysplasia of the hip (DDH). It significantly impairs hip function in the young, and may lead to debilitating early‐onset osteoarthritis in adults. To our knowledge no thorough study of a large skeletal population has ever been undertaken to determine the wide range of diagnostic criteria for this condition in pathological specimens. To identify these criteria we have analysed the cases of developmental dislocation from a large series of 6000 individuals (6580 hips) from the medieval cemetery at Spitalfields in London, UK. We describe the changes at the true acetabulum, and have created a four‐stage classification of the false acetabulum. The skeletal response to the altered biomechanics and limb shortening that occurs in developmental dislocation is described in the pelvis, lower limb and spine. This includes asymmetric growth in childhood, and asymmetric degenerative change in adulthood. We conclude with a discussion of the clinical literature on developmental dislocation of the hip that will aid palaeopathologists to estimate the symptoms that an excavated individual may have experienced during their lifetime.

Mortality date estimation using fetal pronghorn remains

Pronghorn (Antilocapra americana) fetal remains are sometimes recovered from archaeological contexts. Pronghorn have consistent reproductive schedules so their remains may provide information on seasonality of site occupation and number of mortality events. To investigate the reliability of fetal remains for seasonality and mortality event assessment, bone size and tooth eruption were measured in a sample of modern fetal pronghorn remains with known mortality dates. Results indicate a strong correlation between bone size and mortality date, but no significant correlation between tooth eruption level and mortality date. Fetal bone size was used to estimate a late April or early May mortality date at both the Oyster Ridge (48UT35) and Trappers Point (48SU1006) archaeological sites. The number of mortality events at Trappers Point was also investigated. Copyright © 2007 John Wiley & Sons, Ltd.     

A case of dyschondrosteosis in an Anglo‐Saxon skeleton

Osteological examination of a 9^th–11^th century skeleton from Black Gate Cemetery, Newcastle‐upon‐Tyne, reveals Madelung's deformity of both forearms and shortened stature due to reduced tibial length. These are indicative of dyschondrosteosis, a genetically transmitted mild form of mesomelia. This case adds to a small but growing presence of this condition in pre‐modern societies.

A case of multiple metastasis in Late Holocene hunter‐gatherers from the Argentine Pampean region

Chenque I site is a prehistoric cemetery located in Lihué Calel National Park (La Pampa province) in the Western Pampean region of Argentina. Hunter‐gatherer societies made use of this site during the Final Late Holocene for at least 700 years (1030–370 BP). Currently 41 burial structures have been excavated, and more than 150 individuals have been recovered. There is great variability in mortuary patterns at the site (simple, multiple, primary, secondary burials, and also a variant not previously observed in the region). The life‐ways of this population have been investigated through the evaluation of several biological and cultural factors. Several pathological conditions have also been identified in this cemetery. Burial no. 12 contains a skeleton of an adult male that shows multiple pathological lesions, compatible with a neoplastic disease. These lesions have been analysed using several methodological strategies: macroscopic, radiological and microscopic. This is the first time that this kind of disease has been identified from a prehistoric burial in Argentina. In this paper the location and characteristics of the lesions are evaluated, and the different neoplastic diseases that could have produced them are discussed. Since the people buried in this cemetery belonged to highly mobile societies, a key issue is to infer the consequences that this disease would have had on the dynamics of the group in which this person lived, because of the gradual deterioration of his health and physical strength.

From limestone caves to concrete graves: 3000 years of mortuary practice in the Palauan archipelago,Micronesia

Human skeletal remains have been discovered from a variety of contexts in the Palauan archipelago of western Micronesia. These include caves, rockshelters, earthen mounds, stone platforms, midden burials, crypts, sarcophagi, and historic period gravesites. Recent excavation of a prehistoric cemetery in a rockshelter on Orrak Island dating from ca 1000 BC–AD 200, combined with nearly contemporaneous surface finds in caves on both Orrak and other nearby islands, shed light on the earliest known burial practices in Palau. Interment in limestone caves and rockshelters was then replaced in succession by burial in earthwork terraces, beneath stone platforms, in middens, within limestone slab crypts and at least one known stone sarcophagus, and finally in Western or Asian‐style gravesites with headstones. Here we present the first major synthesis of mortuary patterns in Palau from the earliest periods of known settlement (ca. 1000 BC) to modern times. Understanding how these burial practices change over time provides valuable insight into changing sociocultural practices within Palauan society, including how contact with outsiders during the historical period drastically altered traditional mortuary behaviours.
