Targeted Muscle Reinnervation in the Upper Arm: A Functional Anatomical Study.

Background: The aim of this study was to accurately locate the neural fascicle controlling hand movement in the upper arm, to enhance expression of motor intention after targeted muscle reinnervation.

Methods: The right sides of the median, ulnar and radial nerves were dissected from distal to proximal in 6 fresh cadaver specimens. The sectional location and diameter of the functional fascicle were measured at 10 and 20 cm below the acromion.

STMixer: A One-Stage Sparse Action Detector.

Traditional video action detectors typically adopt the two-stage pipeline, where a person detector is first employed to generate actor boxes and then 3D RoIAlign is used to extract actor-specific features for action recognition. This detection paradigm requires multi-stage training and inference, and the feature sampling is only constrained inside the box, failing to effectively leverage richer context information outside. Recently, several query-based action detectors have been proposed to predict action instances in an end-to-end manner.

Miniplate and K-Wire Fixation for Type Vb Jersey Finger: A Case Series of Nine Patients.

Purpose: The aim of this study was to present the results of plate and K-wire fixation for type Vb jersey finger.

Methods: We used a miniplate system combined with a K-wire to treat nine cases of acute type Vb jersey finger injury. The fracture healing time, functional outcomes, and complications were assessed.
