Health-related quality of life in patients treated with en bloc resection for primary tumors of the spine.

Study Design: Retrospective analysis.

Objective: The aim of this study is to evaluate the functional outcomes and the health-related quality of life (HRQOL) in patients undergoing en bloc resection of spinal tumor.

Summary Of Background Data: En bloc resection in the spine is a surgical procedure designed to completely remove a tumor in one piece, with wide margins preserved, in order to reduce the risk of local recurrences.

Experimental ex vivo characterization of the biomechanical effects of laminectomy and posterior fixation of the lumbo-sacral spine.

Laminectomy and posterior fixation are well-established surgical techniques to decompress nervous structures in case of lumbar spinal stenosis. While laminectomy is suspected to increase the instability of the spine, posterior fixation is associated with some complications such as adjacent segment degeneration. This study aimed to investigate how laminectomy and posterior fixation alter the biomechanics of the lumbar spine in terms of range of motion (ROM) and strains on the intervertebral discs.

Evolution and Innovations in Bone Marrow Cellular Therapy for Musculoskeletal Disorders: Tracing the Historical Trajectory and Contemporary Advances.

Bone marrow cellular therapy has undergone a remarkable evolution, significantly impacting the treatment of musculoskeletal disorders. This review traces the historical trajectory from early mythological references to contemporary scientific advancements. The groundbreaking work of Friedenstein in 1968, identifying fibroblast colony-forming cells in bone marrow, laid the foundation for future studies.

Intentional Enneking-inappropriate surgery and high-energy particle therapy for unresectable osteogenic sarcoma of the spine: a retrospective study.

Objective: The aim of this study was to compare the outcome of intralesional gross-total resection (GTR) followed by high-energy particle therapy with en bloc and intralesional resections.

Methods: A retrospective study of patients diagnosed with primary osteogenic sarcoma (OGS) of the spine between 2009 and 2020 was conducted. Demographic information, including age, affected site, tumor volume, and Weinstein-Boriani-Biagini stage, was collected.

Effect of two-level decompressive procedures on the biomechanics of the lumbo-sacral spine: an study.

Hemilaminectomy and laminectomy are decompressive procedures commonly used in case of lumbar spinal stenosis, which involve the removal of the posterior elements of the spine. These procedures may compromise the stability of the spine segment and create critical strains in the intervertebral discs. Thus, this study aimed to investigate if decompressive procedures could alter the biomechanics of the lumbar spine.
