AI Article Synopsis
- - A 55-year-old woman experienced worsening weakness and muscle atrophy in her right hand, specifically affecting the thenar muscles, with no sensory issues noted.
- - She had a background of carpal tunnel syndrome and previously had surgery for it, prompting an exploration of her hand weakness's underlying causes.
- - The case highlights the importance of understanding muscle innervation, provides a structured way to diagnose this hand weakness, and offers a range of potential diagnoses for similar clinical presentations.
Article Abstract
Hand weakness is a frequent chief concern in neurology practice. We report a case of a 55-year-old woman presenting with a chronic, gradually worsening right hand weakness and atrophy, selectively affecting the thenar muscles, without any sensory symptoms. She had a history of carpal tunnel syndrome and previously underwent surgical carpal tunnel release. This case delves into the differential diagnosis of hand weakness and atrophy, emphasizing the significance of myotomal innervation in intrinsic hand muscles. Furthermore, it outlines a systematic approach to diagnosing an uncommon cause for a common clinical presentation, offering a comprehensive differential diagnosis, and exploring various possible causes.

In the last 10 years, have our polytrauma patients become geriatric? The emergency trauma bay in the context of demographic change.
Eur J Trauma Emerg Surg
January 2025
Clinic of Trauma, Hand and Reconstructive Surgery, University of Rostock, Schillingallee 35, 18055, Rostock, Germany.
Purpose: One of the key challenges trauma centres are currently facing is the management of polytraumata in an ageing population. The aim of this study is to assess the extent to which demographic changes are reflected in the trauma bay population and the impact on geriatric polytrauma patient outcomes.
Methods: This is a retrospective single-centre cohort study of a level one trauma centre in Germany.

Cervical fracture dislocation often leads to neurological deficits, manifesting with sensory and motor symptoms, which may persist even after surgical intervention. We presented two cases with mild neurological deficits following such injuries. In Case 1, the patient presented with left-hand numbness 1 month after a car accident.

Background: Sarcopenia, a key aspect of malnutrition in liver cirrhosis (LC), affects 30-70% of LC patients. Given the inconsistent results from RCTs on branched-chain amino acids (BCAAs) for treating sarcopenia in LC, we conducted a systematic review and meta-analysis to assess the efficacy and safety of BCAAs for sarcopenia management in LC patients.
Methods: A systematic review and meta-analysis synthesizing evidence from RCTs obtained from PubMed, Embase, Cochrane, Scopus, and Web of Science from inception to April 2024.
Radial nerve at Fhrose's arcade: a new technique of release under total ultrasound guidance. First experience.
Hand Surg Rehabil

Department of Hand Surgery, Clinique du Pré, Le Mans, France; Ultrasound-guided hand surgery center, Versailles, France.
Radial nerve compression at the arcade of Frohse is a rare but significant condition that typically presents with pain primarily after exertion and at night on the dorsal side of the forearm, more distally than tennis elbow pain, and weakness of the wrist extensors and the long fingers and thumb extensors. Traditional treatment often involves open surgery, resulting in significant scarring. This study introduces a novel percutaneous radial nerve release technique under complete ultrasound guidance and highlights its efficacy and safety.
