Introduction And Importance: Radial nerve injury is very common in supracondylar humerus fractures, but radial nerve entrapment between the fracture ends after closed reduction is very rare, and we report a case of radial nerve entrapment after closed reduction.
Case Presentation: A 7-year-old boy was admitted to the Department of Pediatric Orthopedics 24 days after closed reduction of a supracondylar fracture of the humerus with radial nerve injury. Preoperative ultrasound showed radial nerve entrapment between the fracture ends, which was confirmed by surgery. After nerve release surgery, the radial nerve recovered well.
Clinical Discussion: How to treat supracondylar humerus fractures in case of nerve damage remains controversial. We presented a rare case with radial nerve injury after supracondylar humerus fracture caused complete motor palsy in which the main trunk of the radial nerve above the right elbow traveled posterior to the fracture site. Awareness of the status of the nerve before and after surgery can help in the clinical decision to perform a concomitant nerve exploration, and in the context of this, ultrasound may be more helpful.
Conclusion: We recommend identifying the radial nerve using ultrasound during the closed reduction. If the nerve is entrapped between the fracture ends, exploration is recommended. For cases without entrapment, closed reduction with Kirschner wire fixation can be performed first, and the nerve should be re-examined with ultrasound.

Epithelioid sarcomas are rare soft tissue tumors and have possibility to involve the peripheral nerve and present as sensory and motor disorders. The symptoms are similar to those of nerve compression diseases. This situation is extremely rare in clinic and was only reported as several case reports in literature.

Introduction: This study aims to summarize the retinal and choroidal microvascular features detected by optical coherence tomography angiography (OCTA) in the affected and fellow eyes of patients with retinal vein occlusion (RVO).
Methods: A comprehensive search of the PubMed, Embase, and Ovid databases was conducted to identify studies comparing OCTA metrics among RVO, RVO-fellow, and control eyes. Outcomes of interest included parameters related to foveal avascular zone (FAZ) and fovea- and optic nerve head (ONH)-centered perfusion measurements of superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris layer.

Introduction Paediatric forearm fractures are common, but isolated radial diaphyseal fractures are rare, representing a small subset. Unlike fractures involving both the radius and ulna, these fractures lack well-established management guidelines. The potential for alignment loss during treatment underscores the need for specific protocols.

Objective: Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) is a novel steroid sensitive autoimmune disease, without a diagnostic consensus. The purpose of this study was to improve early GFAP-A diagnosis by increasing awareness of key clinical characteristics and imaging manifestations.
Methods: Medical records of 13 patients with anti-GFAP antibodies in serum or cerebrospinal fluid (CSF) were reviewed for cross-sectional and longitudinal analysis of clinical and magnetic resonance imaging (MRI) findings.
Wrist posture unpredictably affects perception of targeted transcutaneous electrical nerve stimulation with wrist-placed electrodes.
Front Neurosci

Research and Exploratory Development Department, Johns Hopkins University Applied Physics Laboratory, Laurel, MD, United States.
Objective: Targeted transcutaneous electrical nerve stimulation (tTENS) is a non-invasive neural stimulation technique that involves activating sensory nerve fibers to elicit tactile sensations in a distal, or referred, location. Though tTENS is a promising approach for delivering haptic feedback in virtual reality or for use by those with somatosensory deficits, it was not known how the perception of tTENS might be influenced by changing wrist position during sensorimotor tasks.
Approach: We worked with 12 able-bodied individuals and delivered tTENS by placing electrodes on the wrist, thus targeting the ulnar, median, and radial nerves, and eliciting tactile sensations in the hand.
