TL;DR

Forearm pronation is associated with widening of the median nerve–ulnar artery interval at the carpal tunnel inlet in healthy adults, and position-dependent anatomical variations in the transverse interval relevant to the ultrasound-defined safe zone are described.

Dynamic ultrasound evaluation of median nerve mobility at the wrist: implications for surgical safety

The MN demonstrates measurable positional changes at the distal forearm during finger, wrist, and forearm movements that reduce the reliability of assuming a constant “safe” location between PL and FCR and should be considered when planning volar wrist approaches and performing percutaneous or minimally invasive proced...

Effect of Isometric deviation and forearm position on the Scapholunate Space - An in Vivo Ultrasound Study.

PURPOSE To investigate the in vivo effects of forearm rotation and selective isometric wrist muscle activation on the dorsal scapholunate (SL) interval using dynamic ultrasonography, and to determine whether previously described cadaveric biomechanical mechanisms are reproducible in healthy subjects. METHODS Twenty-f...

Carpal tunnel decompression through the flexor carpi radialis approach: a cadaveric comparative study.

INTRODUCTION Carpal tunnel syndrome may occur in association with distal radial fractures, and decompression is sometimes considered at the time of fixation. The flexor carpi radialis approach used for anterior plating may allow decompression without extending the incision into the palm. This study compared intracarpal...

Risk of radial nerve injury during deltoid intramuscular injection in shoulder internal rotation and abduction position-cadaveric anatomical study

ABSTRACT Radial nerve injury following intramuscular injection into the upper arm is rare but clinically significant. Although injection-site selection is important, the effect of shoulder position, particularly internal rotation, on radial nerve location remains unclear. Because the radial nerve courses within the tri...

Sciatic Nerve Bifurcation Level and its Anatomical Relationship to the Piriformis Muscle: A Magnetic Resonance Imaging–Based Assessment in the Iraqi Population

Background: The sciatic nerve is the major nerve supply to the lower extremity and a critical structure in orthopedic surgery, radiologic evaluation, and regional anesthesia. Precise characterization of its relationship to the piriformis muscle is essential for safe procedural planning and for understanding anatomical...

Percutaneous Ultrasonography-guided Release of the Transverse Carpal Ligament versus Open Surgery for Carpal Tunnel Syndrome: A Prospective Comparative Study

Purpose: To compare clinical outcomes between ultrasonography-guided percutaneous and open transverse carpal ligament (TCL) release for carpal tunnel syndrome at short-term follow-up. Methods: A prospective cohort study was conducted in 200 patients with CTS (100 per group) treated with either ultrasonography-guided pe...
