Functional measurements of ear pathology in patients and cadaveric preparations
This work investigated the utility of reflectance (R), a measure of middle-ear mobility, in the differential diagnosis of pathologies responsible for conductive hearing loss (CHL). Current clinical practice cannot distinguish the multiple pathologies that produce conductive hearing loss in patients …

Variations in the circulus arteriosus cerebri in a South African cadaveric sample
The circulus arteriosus cerebri (CAC) or Circle of Willis is a highly variable arterial system at the base of the brain that allows for collateral blood flow, granting a protective effect during ischaemic events. Owing to variations, it may not compensate sufficiently during such events. Some CAC …

Comparing Wear of the Osteoarthritic Temporomandibular Joint and Distal Interphalangeal Joint: A Cadaveric Study
… (DIPJ). While most OA studies rely on imaging, cadaveric dissection enables direct assessment of articular surface wear and subchondral changes. METHODS. Twenty TMJs and DIPJs from ten cadaveric donors were dissected to determine degeneration severity and the distribution of osteoarthritic wear …

Perceptions of Family Members of Cadaveric Organ Donors Towards Selected Issues of the Organ Donation Process
<p>Families of organ donors have faced a deeply emotional experience. These individuals have not only experienced the loss of a family member, they have also consented to donate their family member's organs. The purpose of this study was to determine from a donor family perspective how the organ …

Cancellous bone use in the estimation of sex in a South African cadaveric and forensic sample
The increasing number of unidentified individuals has become a growing concern worldwide. These individuals, whose identities remain unknown following medico-legal autopsy, present a complex challenge for authorities and communities alike. Forensic anthropology is a valuable tool to assist in the …

The design and cadaveric assessment of a new artifial first metatarsophalangeal joint replacement for the great toe
… to verify the biomechanical design principles, cadaveric FMTP joints were tested for range of motion before and after inserting the prostheses. The results were compared to the range of motions obtained from a dry bone specimen, and to the most successful FMTPJ design to date- a double-stem …
