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.

Moderate sagittal plane deformity patients have similar radiographic and functional outcomes with either anterior or posterior surgery.

Purpose: This study aimed to compare the functional and radiographic outcomes of two surgical interventions for adult spinal deformity (ASD): anterior lumbar interbody fusion with anterior column realignment (ALIF-ACR) and posterior approach using Smith-Peterson osteotomy with transforaminal lumbar interbody fusion and pedicle screw fixation (TLIF-Schwab2).

Methods: A retrospective cohort study included 61 ASD patients treated surgically between 2019 and 2020 at a single tertiary orthopedic specialty hospital. Patients were divided into two groups: Group 1 (ALIF-ACR, 29 patients) and Group 2 (TLIF-Schwab2, 32 patients).

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.

Reliability and Validity of Adapted Russian Version of Hospital for Special Surgery Lumbar Spine Surgery Expectations Survey.

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.
