Case: A 58-year-old woman underwent delayed fixation of an unstable distal radius fracture. At staged hardware removal, an isolated rupture of extensor carpi radialis brevis (ECRB) was discovered and tenodesed to extensor carpi radialis longus acutely. The surgical intervention allowed her to return to gardening at 2 weeks after the hardware removal with preserved function and pain control at 13-month follow-up, respectively.
Conclusion: We present a rare complication of isolated abrasive ECRB rupture with an intra-articular distal radius fracture treated with a late decision for surgery. Our surgical intervention resolved the patient's pain and preserved function in this case.

Background: Extensor indicis proprius (EIP) transfer augmented with proximal extensor pollicis longus (EPL) stump lengthening restores thumb extension and optimizes function in cases of chronic EPL tendon ruptures, which impair hand dexterity and fine motor skills. Traditional EIP-to-EPL transfers often disrupt the natural oblique course of the EPL around the Lister tubercle, leading to functional deficits. This dual-tendon transfer preserves anatomical alignment and improves thumb biomechanics, enhancing extension strength and the adduction moment arm at the carpometacarpal (CMC) joint.

Purpose: This study aimed to evaluate the intraoperative localization and prognostic utility of electrophysiologic monitoring for upper limb and hand muscle groups during contralateral C7 nerve transfer surgery.
Methods: In this retrospective, dual-center study, patients with spastic hemiparesis of a single upper limb who underwent contralateral C7 nerve transfer between July 2022 and November 2023 at the First Affiliated Hospital of Soochow University and Nanjing Drum Tower Hospital were included. Sensory, motor, and muscle tone changes were assessed using free electromyography, compound muscle action potentials, somatosensory evoked potentials, and transcranial electrical stimulation motor evoked potentials.

Repetitive transcranial magnetic stimulation (rTMS) holds promise as a noninvasive pain treatment. Given the link between individual peak alpha frequency (PAF) of resting-state electroencephalographic recordings and pain sensitivity, and the potential for rTMS to modulate PAF, we investigated these relationships through a secondary analysis of established rTMS-induced analgesia in an experimental model of sustained muscle pain. In a randomized, single-blind, sham-controlled experiment, 30 healthy adults underwent either active (n = 15) or sham (n = 15) high-frequency rTMS (20 min) to the left dorsolateral prefrontal cortex for five consecutive days following the induction of sustained experimental pain by nerve growth factor (NGF) injected into the right extensor carpi radialis brevis muscle.

Background: Carpometacarpal (CM) joint osteoarthritis of the thumb is characterized by pain and impaired thumb function in terms of pinch and range of motion. Here, we newly adopted a trapeziectomy with a graft-augmented ligament reconstruction procedure, in which the reconstructed ligament is reinforced using a half-slip extensor carpi radialis longus (ECRL) tendon.
Methods: From 2015 to 2022, 101 hands of 95 patients with CM joint osteoarthritis of the thumb underwent trapeziectomy with graft-augmented ligament reconstruction using the half-slip ECRL tendon to reconstruct the ligament.

Objectives: Acute compartment syndrome (ACS) is a medical emergency that requires timely intervention, and delays in treatment can lead to severe complications such as nerve injury, muscle necrosis, amputation, and even death. Definitive treatment of ACS requires a fasciotomy. Currently, there is no consensus on the best approach for a forearm fasciotomy; compartment release is most commonly done through volar or combined volar and dorsal incisions.
