A prospective multicenter spine oncology registry collecting real-world data on patients undergoing surgical treatment and radiation therapy for spinal tumors. The registry aims to improve understanding of treatment patterns and outcomes, supporting evidence-based care for patients with metastatic and primary spine tumors.

A retrospective multicenter study evaluating the incidence, timing, and risk factors associated with upper instrumented vertebra (UIV) screw loosening following thoracolumbar spinal fusion. Leveraging standardized radiographic review across BTNC institutions, the project seeks to identify factors that may influence construct durability and patient outcomes.

A prospective, randomized, non-inferiority study evaluating outcomes in patients undergoing cranioplasty following decompressive hemicraniectomy. The study compares autologous bone reconstruction with customized allograft and synthetic implant options, including polyetheretherketone (PEEK) and polymethyl methacrylate (PMMA) implants. Through multicenter collaboration, the study aims to generate high-quality evidence to inform reconstructive decision-making and improve outcomes following cranial surgery.
