“Abductor Sparing”: A New Selective Involvement in ALS

Muscle &Nerve, Volume 74, Issue 4, Page 1263-1269, October 2026.
ABSTRACT Introduction/Aims Various signs of selective muscle involvement have been reported in amyotrophic lateral sclerosis (ALS) but such studies for the lower limbs are scarce. We formed a preliminary impression that hip abductors (Ab) are often preserved in ALS.

Dorsal C1–2 Spinal Cord Compression After Reduction of Atlantoaxial Posterior Dislocation Associated With Os Odontoideum: A Case Report and Literature Review

Orthopaedic Surgery, Volume 18, Issue 10, Page 2269-2275, October 2026.
Successful reduction of os odontoideum‐associated atlantoaxial posterior dislocation may not always guarantee adequate C1–2 canal space. In patients with congenital atlas hypoplasia or posterior arch osteophytes, postreduction dorsal cord compression should be anticipated, and C1 posterior arch decompression may be required to prevent neurological ...

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

Annals of Clinical and Translational Neurology, Volume 13, Issue 3, Page 504-516, March 2026.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)
