简要总结
This is a prospective, multi-center, observational Post-Market Clinical Follow-Up (PMCF) study designed to collect additional safety and clinical performance data on CE-marked Titania® spinal instrumentation and fusion systems, and Bonegraft® bone filling materials (synthetic bone grafts and bone cements). The study aims to evaluate short-term (12-month) safety and effectiveness, identify previously unknown side effects, monitor defined complications, and assess risks based on real-world evidence in patients undergoing spinal surgery. All investigated products are used within their intended purpose under routine clinical practice.
详细描述
This prospective, multi-center, observational study evaluates the safety and clinical performance of Titania® spinal instrumentation and fusion systems (manufactured by METROSAN End. ve Elk. Mek. Cihazlar ve Tibbi Malz. San. Tic. Ltd. Sti.) and Bonegraft® bone filling materials, including synthetic bone grafts and bone cements (manufactured by Bonegraft Biyolojik Malzemeler San. ve Tic. A.S.). All investigational products are CE marked and registered in the Turkish Ministry of Health's Product Tracking System (UTS).
The study is purely observational; no additional medical procedures, interventions, or tests beyond routine clinical practice will be performed. Data collection includes retrospective review of preoperative and intraoperative information from patient files, followed by prospective follow-up data collection using a study-specific Electronic Case Report Form (e-CRF). Subjects will be evaluated during routine clinical visits at post-operative Day 12 (±5 days), Week 6, and Months 3, 6, and 12.
Seventeen distinct product groups are evaluated independently, covering cervical interbody fusion cages (Titanium and PEEK), posterior cervical stabilization systems, cervical plate systems, cervical dynamic stabilization systems, cervical disc prostheses (Titanium and PEEK), lumbar interbody fusion cages (Titanium and PEEK), interspinous fusion devices, posterior thoracolumbar stabilization systems, posterior thoracolumbar clamp systems, thoracolumbar dynamic stabilization systems, and bone filling materials (bone cements and synthetic bone grafts).
The enrollment period is planned for 12 months, followed by a 12-month follow-up for each participant. An additional 5 months is allocated for data analysis and reporting, with a total study duration of 29 months. The total estimated enrollment is 561 subjects.
The study is conducted in accordance with the EU Medical Device Regulation (MDR) 2017/745, the Turkish Medical Device Regulation (dated 02.06.2021), ICH-GCP guidelines, the Declaration of Helsinki, and applicable Turkish legislation regarding the protection of personal data.
