Bilateral hip dysplasia in a South African male: A case study from the 17-18th century.

OBJECTIVE: To identify, critically analyse and describe severe bilateral skeletal pathology involving the ossa coxae of an individual from historic era Cape Town. MATERIALS: A single individual from the University of Cape Town's Human Skeletal Repository was analysed under research approval (HREC# 035/2021). METHODS: An osteobiography was constructed, radiocarbon dating and isotopic analyses were conducted. Pathological description and contextualised disability analyses followed, along with differential diagnosis. The pelvis and femora were visualised macroscopically and radiographically. RESULTS: This individual was a non-European middle-aged adult male who lived in the 17-18th centuries CE. Morphological changes showed hypoplastic hips with collapsed femoral heads and neoacetabulae. A diagnosis of developmental dysplasia of the hips (DDH) was made. Then a contextualised disability analysis including consideration of the clinical and functional impacts of the condition were applied. No signs of maltreatment, physiological stress or persistent infections were present. His bones were well developed, illustrating mobility and use. CONCLUSIONS: He developed DDH early in life and lived through adulthood, and his strong, healthy bones suggest resilience, some mobility and contribution to society through less physically demanding tasks. SIGNIFICANCE: Value for palaepathological analyses to inform and understand disability and culturally significant health mediation to offer a more objective interpretation and improve understanding of past people. It expands our understanding of the presence of DDH globally and in Africa and provides insight into disease impact for individuals with bilateral expression. SUGGESTIONS FOR FUTURE RESEARCH: Further contextual research is required. LIMITATIONS: Poor scene recovery hindered in-depth care analysis and interpretation of the condition.

Biomaterials use in Mulago National Referral Hospital in Kampala, Uganda: Access and affordability.

Students in Biomaterials BBE3102 at Makerere University in Kampala, Uganda were assigned semester long group projects in the first semester of the 2014-15 academic year to determine the biomaterials type and usage in Mulago National Referral Hospital, which is emblematic of large public hospitals across East Africa. Information gathering was conducted through student interviews with Mulago physicians because there were no archival records. The students divided themselves into seven project groups covering biomaterials use in the areas of wound closure, dental and oral surgery, cardiology, burn care, bone repair, ophthalmology and total joint replacement. As in the developed world, the majority of biomaterials used in Mulago are basic wound closure materials, dental materials, and bone fixation materials, all of which are comparatively inexpensive, easy to store, and readily available from either the government or local suppliers; however, there were significant issues with the implant supply chain, affordability, and patient compliance and follow-up in cases where specialty expertise and expensive implants were employed.
