A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout
Journal of Anatomy, EarlyView.Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

How do forelimb long bones adapt in rhinoceroses? An in‐depth examination of their microanatomy
Journal of Anatomy, EarlyView.Here, we study the bone structure in the forelimb long bones of the five extant species of rhinoceroses. By combining traditional description of virtual sections made on the bones (A) with in‐depth cartographies of the variation of bone compactness and anisotropy (B), we show how bone tissue can adapt to extreme forces and constraints in the second ...

Scintigraphic assessment of bone status at one year following hip resurfacing : comparison of two surgical approaches using SPECT-CT scan [PDF]
, 2012 Objectives: To study the vascularity and bone metabolism of the femoral head/neck following hip resurfacing arthroplasty, and to use these results to compare the posterior and the trochanteric-flip approaches.

Journal of Anatomy, EarlyView.A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Arthroscopically Assisted Treatment of Intraosseous Ganglions of the Lunate
, 2008 Intraosseous ganglia (IOGs) of the lunate are a relatively rare, but by no means insignificant, condition because treatment by traditional open curettage and bone grafting can lead to ongoing pain and stiffness of the wrist.An arthroscopically assisted ...

Journal of Anatomy, EarlyView.We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Recognizing Signs of Abusive Head Trauma
Journal of Paediatrics and Child Health, EarlyView.ABSTRACT Background Abusive head trauma (AHT) remains the leading cause of fatal traumatic brain injury in infants and young children. Diagnosis is frequently delayed or missed due to nonspecific clinical presentation and unreliable histories, making neuroimaging a critical component of the diagnostic process. Objective This review synthesises computed
