Cervical carotid disease is typical atherosclerosis, which is responsible for ischemic stroke. The effectiveness of carotid endarterectomy (CEA) for advanced carotid stenosis has been established in many large studies, and CEA is the gold standard in surgical treatment. On the other hand, endovascular carotid artery stenting (CAS) has become increasingly popular recently. Read More

Intracortical mapping in monkeys revealed a full body map in all four cytoarchitectonic subdivisions of the contralateral primary somatosensory cortex (S1), as well as positive associations between spatio-tactile acuity performance of the fingers and their representation field size especially within cytoarchitectonic Area 3b and Area 1. Previous non-invasive investigations on these associations in humans assumed a monotonous decrease of representation field size from index finger to little finger although the field sizes are known to change in response to training or in disease. Recent developments improved noninvasive functional mapping of S1 by a) adding a cognitive task during repetitive stimulation to decrease habituation to the stimuli, b) smaller voxel size of fMRI-sequences, c) surface-based analysis accounting for cortical curvature, and d) increase of spatial specificity for fMRI data analysis by avoidance of smoothing, partial volume effects, and pial vein signals.

Acta Orthop Traumatol Turc 2021 Jan;55(1):57-61

Clinic of Orthopaedics and Traumatology, VM Medical Park Pendik Hospital, İstanbul, Turkey.

Objective: This study aimed to present the mid-term clinical and radiographic outcomes of patients with perilunate injuries treated with open reduction and internal fixation (ORIF).

Methods: Patients who underwent ORIF due to perilunate injuries from 2004 to 2015 were retrospectively reviewed. Surgery was mostly performed using a standard dorsal approach. Read More

Bone Jt Open 2021 Mar;2(3):141-149

Hand & Wrist Unit, La Tour Hospital, Geneva, Switzerland.

Aims: The objective of this systematic review was to describe trapeziectomy outcomes and complications in the context of osteoarthritis of the base of the thumb after a five-year minimum follow-up.

Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to guide study design, and 267 full-text articles were assessed for eligibility. After exclusion criteria application, 22 studies were included, involving 728 patients and 823 trapeziectomies. Read More

Eur J Appl Physiol 2021 Mar 1. Epub 2021 Mar 1.

EA4660, C3S Laboratory, UPFR Sports, University of Bourgogne Franche-Comté, 31, Chemin de l'Epitaphe, 25000, Besançon, France.

Purpose: This study investigated the effects of force and electromyographic (EMG) feedbacks on forearm muscle activations and handgrip maximal isometric voluntary contraction (MIVC).

Methods: Sixteen males performed a set of MIVC in four different feedback conditions: (1) NO-FB: no feedback is given to the participant; (2) FORCE-FB: participants received a visual feedback of the produced force; (3) AGO-FB: participants received a visual feedback of the EMG activity of two agonist grip muscles; (4) ANTAGO-FB: participants received a visual feedback of the EMG activity of two hand extensors muscles. Each feedback was displayed by monitoring the signal of either force or electrical activity of the corresponding muscles. Read More
