Case: A 67-year-old woman presented 9 months after a closed midshaft humerus fracture with a new onset radial nerve palsy. Radiographs demonstrated a hypertrophic nonunion. Upon exploration, the radial nerve was in continuity and entrapped in fracture callus. It was extricated from the callus, and an open reduction and plate fixation was performed. Full radial nerve function returned by 3 months.
Conclusion: We recommend that delayed onset radial nerve palsies be treated on a semiurgent basis with radial nerve exploration and decompression followed by internal fixation to achieve primary bone healing and minimize fracture callus formation.

Influence of sex on sympathetic vasomotor outflow responses to passive leg raising in young individuals.

Department of Biomedical Engineering, Toyo University, Kawagoe, Japan.
The purpose of this study was to clarify sex differences in the inhibition of sympathetic vasomotor outflow which is caused by the loading of cardiopulmonary baroreceptors. Ten young males and ten age-matched females participated. The participants underwent a passive leg raising (PLR) test wherein they were positioned supine (baseline, 0º), and their lower limbs were lifted passively at 10º, 20º, 30º, and 40º.

Objectives: Lateral sagittal infraclavicular approach is frequently used because it has less risk of complications and provides rapid and adequate regional anesthesia. Due to the fact that the brachial plexus is deeper in the infraclavicular region and the approach angle is sharper, it can be technically challenging. In this study, we aimed to compare the costoclavicular approach, which is a newly defined approach, with the lateral sagittal infraclavicular brachial plexus block.

Background: The main treatment methods for humeral shaft fractures include minimally invasive plate osteosynthesis (MIPO), intramedullary nailing (IMN), open reduction and internal fixation (ORF), and non-operative treatment (NonOP). However, the optimal treatment plan remains unclear. This article utilizes a network meta-analysis to compare the therapeutic effects of MIPO, IMN, ORF, and NonOP for the treatment of humeral shaft fractures.

Radial nerve compression at the arcade of Frohse is a rare but significant condition that typically presents with pain primarily after exertion and at night on the dorsal side of the forearm, more distally than tennis elbow pain, and weakness of the wrist extensors and the long fingers and thumb extensors. Traditional treatment often involves open surgery, resulting in significant scarring. This study introduces a novel percutaneous radial nerve release technique under complete ultrasound guidance and highlights its efficacy and safety.

Purpose: The purpose of this study was to report a timeframe for neurologic recovery of complete radial nerve palsies in patients with humeral shaft fractures treated with internal fixation.
Methods: We retrospectively analyzed the data of patients who underwent surgical treatment of a humeral shaft fracture between 2016 and 2021 at a level I trauma center. Patients with complete sensory and motor radial nerve palsy were identified.
