[Translated article] Efficacy of early versus delayed spinal cord decompression in neurological recovery after traumatic spinal cord injury: Systematic review and meta-analysis.

Study Design: Systematic review and meta-analysis.

Objective: To compare early (<24h) versus late (>24h) spinal cord decompression on neurological recovery in patients with acute spinal cord injury.

Methods: A systematic review was performed according to the PRISMA protocol to identify studies published up to December 2022.

[The morbidity of the posterior iliac crest bone graft harvesting could be an overestimated fact. Study in patients with open posterolateral lumbar fusion].

Introduction: spinal fusion is used to treat, among other pathologies, the degenerative intervertebral disc disease. Autologous iliac crest bone grafting is the golden standard treatment for increasing the rate of fusion; however, it isn't free of complications.

Objectives: to investigate whether patients who have posterior iliac crest graft harvesting and are blinded to the donor site, can identify from which side the graft was harvested, and whether the intensity of this pain is related to the amount of graft obtained.

[Translated article] Relation between the volume of injected cement and the vertebral volume in the clinical outcome and in the appearance of leakage after a percutaneous vertebroplasty.

Objectives: To assess the connection between the volume of injected cement and the vertebral volume measured through a volumetric analysis with a computed tomography (CT scan) in relation to the clinical result and the appearance of a leakage in patients who underwent a percutaneous vertebroplasty after an osteoporotic fracture.

Materials And Methods: A prospective study of 27 patients (18 female-9 male) with an average age of 69 years old (50-81), and with a one-year follow-up. The study group presented 41 vertebrae with osteoporotic fractures that were treated with a percutaneous vertebroplasty with a bilateral transpedicular approach.

[Is the Michigan State University lumbar disc herniation classification reliable among spine surgeons?].

Introduction: there are numerous classifications for herniated discs, such classifications guide professionals about the severity of the lesion, the possible clinical picture of the patient, the most appropriate treatment and are undoubtedly a predictive tool to project the possible results of the therapies used. The main purpose of this work is to validate the inter- and intra-observer reliability of the Michigan State University (MSU) classification among the spine surgeons of our service and also to know the risk factors associated with the patients who underwent lumbar discectomy, the most affected disc level, the clinical presentation and the previous treatments performed in the patients treated by our team.

Material And Methods: 50 nuclear magnetic resonance (MR) images in axial T2 section corresponding to the "maximum disc herniation" level were selected from patients diagnosed and submitted to meningo-radicular release surgery and single level lumbar discectomy retrospectively in the last two years from our database; these images were distributed among three spine surgeons of our institution.

[Application of vancomycin powder on graft. Does the fusion of the rabbits spine is affected?].

Introduction: In vitro studies suggest that vancomycin is highly cytotoxic for osteoblasts. However, several clinical studies in vivo have not provided evidence or determined that effect on osteogenesis. The aim of this work was to investigate the effect of topical vancomycin on a lumbar arthrodesis model on New Zealand white rabbits.

Neurological injury as a complication of spinal surgery: incidence, risk factors, and prognosis.

Study Design: Retrospective cohort study.

Objective: To assess the rate, injury site, aetiology and outcomes in elective spinal surgery patients who sustained a spinal cord injury (SCI).

Setting: SCI national centre Toledo, Spain.
