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.

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.

Patients' expectations are an important determinant in their decision to undergo lumbar spinal surgery-particularly their expectations of recovery after surgery. The Hospital for Special Surgery Lumbar Spine Surgery Expectations Survey (HSS-LSSES) is one tool used to assess this; however, the original version was only available in English. We sought to evaluate the reliability and validity of a translated and adapted Russian-language version of the HSS-LSSES.

Objective: Instrumentation failure in spine tumor surgery is a common reason for revision operation. Increases in patient survival demand a better understanding of the hardware longevity. The study objective was to investigate risk factors for instrumentation failure requiring revision surgery in patients with spinal tumors.

Background: Intraoperative hemorrhage can sometimes be massive in patients with spinal metastasis of renal cell carcinoma (MRCC). Preoperative embolization and local hemostatic agents are routinely use in spinal tumor surgery, but there have been no comparisons between these methods. This report compares the efficiency of various methods of bleeding control and their influence on outcome and survival after decompression procedures for MRCC.
