Rebuilding ships while at sea—Character individuality, homology, and evolutionary innovation

open access: yesJournal of Morphology, Volume 284, Issue 1, January 2023., 2023
Building on a previous account of evolutionary innovation, I propose here that evolutionary novelties are those individualized characters that are not homologous to any characters in the ancestor. Integrating functional and structural perspectives, I argue that functional as well as structural considerations are important for character ...

The accessory renal arteries: A systematic review with meta‐analysis

open access: yesClinical Anatomy, EarlyView.
Abstract The accessory renal arteries (ARAs) are a well‐described variant of the renal vasculature with clinical implications for radiologists, surgeons, and clinicians. The aim of the present systematic review with meta‐analysis was to estimate the pooled prevalence of ARAs, including their variant number, origin, and termination, and to highlight ...

Age‐ and sex‐specific normative values of bone mineral density in the adult glenoid

open access: yesJournal of Orthopaedic Research, Volume 41, Issue 2, Page 263-270, February 2023., 2023
Abstract The objective of this study was to determine the normative bone mineral density (BMD) of cortical and trabecular bone regions in the adult glenoid and its dependence on the subject's age and sex. We analyzed computed tomography (CT) scans of 441 shoulders (310 males, 18–69 years) without any signs of glenohumeral joint pathology.

Anatomical Study of the Retrodural Space of Okada in the Cervical Region: 3D Micro‐CT Findings

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The retrodural space of Okada (RSO) is a potential space located posterior to the ligamentum flavum. It can complicate epidural injections owing to its communication with the epidural space and facet joints. The purpose of this study was to clarify the anatomical structures of the cervical RSO and adjacent ligamentous tissues in cadavers ...

Platelet‐rich plasma versus corticosteroid injections in the management of patients with rotator cuff disease: A systematic review and meta‐analysis

open access: yesJournal of Orthopaedic Research, Volume 41, Issue 1, Page 7-20, January 2023., 2023
Abstract Platelet‐rich plasma (PRP) is an alternative to corticosteroid (CS) injections in managing rotator cuff disease. This meta‐analysis investigated differences between PRP and CS for function and pain scores in significance and minimal clinical important difference (MCID).
