Brain mapping during resection of high-grade brain arteriovenous malformation.

Eloquent brain creates a challenge when resecting brain arteriovenous malformations (bAVMs). Here the authors present their technique of using subcortical motor mapping as an adjunct to increase safety during resection of a high-grade bAVM involving somatosensory cortex as well as cortical spinal tracts and visual tracts. After a bilateral craniotomy, they use direct cortical stimulation of the left motor cortex and subcortical stimulation using a suction stimulator to dynamically map motor tracts during the resection.

Complications of Middle Meningeal Artery Embolization: A Systematic Review and Meta-Analysis.

Background: Middle meningeal artery embolization (MMAE) is an established treatment option for chronic subdural hematoma. The aim of this systematic review and meta-analysis was to establish estimates of the pooled incidence for complications following MMAE.

Methods: PubMed, Embase, and Cochrane were searched for studies reporting complications following MMAE through January 2023.

Feasibility of continuous physical activity monitoring: first-month recovery markers following joint replacement surgery.

Background: The role of physical activity (PA) monitoring during the recovery after orthopaedic surgeries is unclear. This study aimed to explore early changes in the pattern and level of PA following orthopedic surgeries.

Methods: This observational feasibility study included 11 hip replacement patients (four females) with a mean age of 66 years and five knee replacement patients (four females) with a mean age of 65 years.

Pain mechanistic networks: the development using supervised multivariate data analysis and implications for chronic pain.

Chronic postoperative pain is present in approximately 20% of patients undergoing total knee arthroplasty. Studies indicate that pain mechanisms are associated with development and maintenance of chronic postoperative pain. The current study assessed pain sensitivity, inflammation, microRNAs, and psychological factors and combined these in a network to describe chronic postoperative pain.

Multivariable model for gait pattern differentiation in elderly patients with hip and knee osteoarthritis: A wearable sensor approach.

Background: Hip and knee osteoarthritis (OA) patients demonstrate distinct gait patterns, yet detecting subtle abnormalities with wearable sensors remains uncertain. This study aimed to assess a predictive model's efficacy in distinguishing between hip and knee OA gait patterns using accelerometer data.

Method: Participants with hip or knee OA underwent overground walking assessments, recording lower limb accelerations for subsequent time and frequency domain analyses.
