Patient-specific 3D-Printed PEEK implants for spinal tumor surgery.

Aims & Objectives: This study evaluates the feasibility and clinical outcomes of using 3D-printed polyetheretherketone (PEEK) patient-specific implants (PSI) for vertebral body replacement (VBR) in patients with spinal tumors. The research question focuses on postoperative results, implant integration, and complications over a 12-month period.

Methods: A single-center, retrospective case series analyzed five patients who underwent spinal reconstruction after tumor resection using PEEK 3D VBR between April 2022 and June 2023.

Cross-cultural adaptation, reliability, and validity of the Russian version of the Spine Oncology Study Group Outcomes Questionnaire (SOSGOQ2.0).

Objective: The most validated health-related quality-of-life (HRQOL) questionnaire specific to the metastatic spine cancer population is the Spine Oncology Study Group Outcomes Questionnaire version 2 (SOSGOQ2.0). The purpose of this study was to translate and validate a Russian version of the SOSGOQ2.

Conditional survival after surgery for metastatic tumors of the spine: does prognosis change over time?

Purpose: Conditional survival (CS) provides a dynamic prediction of patient survival by incorporating the time an individual has already survived given their disease specific characteristics. The objective of the current study was to estimate CS among patients after surgery for spinal cord compression or spinal instability, as well as stratify CS according to relevant patient- and disease-related characteristics.

Methods: The clinical outcomes of 361 patients undergoing surgical management of metastatic spinal tumors were retrospectively analyzed.
