Fascicle differentiation of upper extremity nerves on high-resolution ultrasound with multimodal microscopic verification

Scientific Reports
This study aimed to compare the fascicular anatomy of upper limb nerves visualized using in situ high-resolution ultrasound (HRUS) with ex vivo imaging modalities, namely, magnetic resonance microscopy (MRM), histological cross-sections (HCS), and ...

Neurophysiological Recovery Following Nerve Transfer Surgery to Restore Upper Limb Function after Cervical Spinal Cord Injury

Annals of Neurology, EarlyView.
Objectives Nerve transfer is a promising intervention for restoring hand and upper limb function after cervical spinal cord injury (SCI), but the timeline of neurophysiological recovery in humans remains unclear. This study aimed to define recovery profiles after nerve transfers to restore upper limb function.

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

The Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

Three‐dimensional digital analysis of musteloid masticatory muscle architecture

The Anatomical Record, EarlyView.
Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

Morphological classification of the temporalis muscle: anatomical, radiological, and surgical perspectives

Frontiers in Surgery
The temporalis muscle (TM) shows substantive morphological variability with direct implications for surgical planning and imaging interpretation. Drawing on cadaveric series and imaging cohorts, we critically synthesise convergent findings on layered ...

Fascicle measurement methods do result in lengths that are significantly different

The Anatomical Record, EarlyView.
A recent comparison of the most prevalent methods for measuring fascicles, in situ measurement versus chemical digestion, concluded that the measurements are indistinguishable based on data from different conspecific individuals. However, our study of contralateral muscles of the same individuals shows that the methods clearly result in statistically ...

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Donor‐To‐Recipient Mean Axonal Count Ratios of Upper Limb Nerves Used in Nerve Transfer Surgery: A Systematic Review of Histomorphometric Cadaveric Studies

Clinical Anatomy, EarlyView.
ABSTRACT Nerve transfer surgery may be performed to restore sensorimotor function following peripheral nerve trauma or dysfunction. There is biological plausibility and limited correlative evidence that donor‐to‐recipient axon count ratios may impact functional outcomes.

Iliac Attachment of the Psoas Major Muscle: Anatomical Study of a Novel Muscle Attachment

Clinical Anatomy, EarlyView.
ABSTRACT The iliopsoas muscle is important functionally and is often encountered during various surgical procedures. During routine cadaveric dissection, a previously undescribed muscular structure was located deep to the iliacus muscle and coursed inferomedially to merge with the posterior aspect of the psoas major, running over the iliopectineal ...

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...
