Dual Mini-Fragment Plate Fixation of Midshaft Clavicle Fractures Demonstrates Fewer Union Complications but Similar Patient-reported Outcomes Compared to Nonoperative Management: A Cohort Study with Mean 3.4 Year Follow-Up.

Purpose: Although open reduction and internal fixation (ORIF) is the gold standard treatment for displaced midshaft clavicle fractures, recent studies have advocated for nonoperative management, citing high rates of reoperation associated with operative intervention. However, no studies have compared nonoperative management to ORIF with dual-plate fixation, which may be associated with lower rates of reoperation compared to single-plate fixation. The purpose of this study was to compare the complications and patient-reported outcomes of dual mini-fragment plate fixation to nonoperative management for displaced midshaft clavicle fractures.

Anionic Olefin Metathesis Catalysts Enable Modification of Unprotected Biomolecules in Water.

Stability problems have limited the uptake of cationic olefin metathesis catalysts in chemical biology. Described herein are anionic catalysts that improve water-solubility, robustness, and compatibility with biomolecules such as DNA. A sulfonate tag is installed on the cyclic (alkyl)(amino) carbene (CAAC) ligand platform, chosen for resistance to degradation by nucleophiles, base, water, and β-elimination.

Preoperative stereotactic radiosurgery for cerebral metastases: safe, effective, and decreases steroid dependency.

Objective: Preoperative stereotactic radiosurgery (SRS) is emerging as a viable alternative to standard postoperative SRS. Studies have suggested that preoperative SRS provides comparable tumor control and overall survival (OS) and may reduce the incidence of leptomeningeal disease (LMD) and adverse radiation effects (AREs). It is unknown, however, if preoperative SRS remains effective in cohorts including large brain metastases (> 14 cm3) or if preoperative SRS affects steroid taper/immunotherapy.

Feasibility and Usability of Augmented Reality Technology in the Orthopaedic Operating Room.

Purpose Of Review: Augmented reality (AR) has gained popularity in various sectors, including gaming, entertainment, and healthcare. The desire for improved surgical navigation within orthopaedic surgery has led to the evaluation of the feasibility and usability of AR in the operating room (OR). However, the safe and effective use of AR technology in the OR necessitates a proper understanding of its capabilities and limitations.
