MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Early evolution of the gular musculature and its innervation in ray‐finned fishes

open access: yesThe Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Clinical Physical Exam Shows High Sensitivity for Detecting Labral Tears in Individuals With Femoroacetabular Impingement Syndrome

open access: yesArthroscopy, EarlyView.
Purpose To determine the diagnostic performance of the combined use of radiographs and physical exam findings, compared with magnetic resonance arthrography (MRA) alone, for the primary diagnosis of labral tears in individuals with femoroacetabular impingement syndrome.

Minimally Invasive Arthroscopic Fixation of Scaphoid Nonunion in Adolescents Shows High Union Rates, Improved Function, and Low Morbidity

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate the clinical, radiographic, and functional outcomes of arthroscopic treatment of scaphoid nonunion in adolescents, using cancellous bone grafting combined with headless compression screw fixation. Methods This retrospective study included adolescent patients treated between 2015 and 2022 with arthroscopically assisted bone grafting ...

Nerve growth factor is sufficient to cause multiple osteoarthritis‐relevant pathological features in naïve murine knee joints

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Nerve growth factor (NGF), a key mediator of pain, is increased in osteoarthritic (OA) joints. Antibodies against NGF show analgesic effects in painful knee OA, but clinical development was stopped due to side‐effects in the joints. Knowledge about the biological effects of NGF on joint tissues is limited.

Endoscopic Resection of Bizarre Parosteal Osteochondromatous Proliferation of the Calcaneocuboid Joint

open access: yesArthroscopy Techniques, EarlyView.
Abstract Bizarre parosteal osteochondromatous proliferation (BPOP), or Nora's lesion, is an unusual, benign, parosteal lesion comprising bone, fibrous tissue, and cartilage. Clinically, the lesions present as slowly growing hard protuberances that are painless in most cases unless they cause local symptoms due to mass effect, including pain, palpable ...

Acromial Osteotomy for Dynamic Posterior Shoulder Instability

open access: yesArthroscopy Techniques, EarlyView.
Abstract Posterior shoulder instability is less prevalent than anterior instability but shows a rising incidence, particularly among young and active individuals. Diagnosis is often challenging due to nonspecific symptoms, leading to delays and underestimation of prevalence. Its etiology is multifactorial, including traumatic events, iatrogenic causes,
