Distinct lesions are derived from notochordal cells (NCDL), ranging from benign to malignant ones. This study presents fifty NCDL cases diagnosed in a tertiary hospital of reference from the past 55 years: forty-two conventional chordomas, including one chondroid chordoma subtype, four benign notochordal cell tumors (BNCT), two conventional chordomas with BNCT foci, and two dedifferentiated chordomas. All patients were adults. ⋯ Sixteen patients died due to tumor-related factors; twenty-eight presented local recurrence, and four developed distant metastases. New therapeutic options are being studied for chordoma cases. Clinical, radiological, and histopathological data are necessary to properly diagnose and follow up of NCDL.

To report the rate of fusion in a sample of patients undergoing lumbar fusion surgery and assess interrater reliability of computed tomography (CT)-based parameters for the assessment of fusion. ⋯ There was only moderate interrater reliability across most radiographic measures used in assessing lumbar fusion status. Reliability was highest when evaluating the presence of interbody fusion. The majority of fusions occurred across the facet joints.

The objective of this study is to evaluate the prognostic value of nutritional scores comprising the Controlling Nutritional Status (CONUT) score and the Prognostic Nutritional Index (PNI), in prediction of multilevel vertebral involvement (> 2 vertebra) in Spinal Tuberculosis (STB). ⋯ Nutritional scores, including CONUT score and PNI, emerged as significant predictors of multilevel STB. CONUT score displayed superior sensitivity, negative predictive value, and overall diagnostic accuracy, while PNI served as a nutritional marker with high specificity and positive predictive value in predicting multilevel involvement in spinal tuberculosis.

Observational Study
The effect of ATLS/PHTLS spinal motion restriction protocol on the incidence of spinal cord injury, a nationwide database study.
To study trends in incidence and outcome of patients with traumatic spinal cord injury (TSCI) in the Netherlands before, during and after implementation of the Advanced Trauma Life Support (ATLS®) and Pre-Hospital Trauma Life Support (PHTLS®)- Spinal Motion Restriction(SMR) protocol. ⋯ Since implementation of the SMR-protocol was aiming to limit TSCI in patients who suffered a spinal fracture, the increase in TSCI is an unexpected finding. Exact explanation for this increase is unclear and the contribution of the SMR-protocol is not fully understood due to confounders in the used datasets. Either way, the scientific evidence supporting this costly time- and labor-intensive SMR-protocol remains debated, along with evidence contradicting it. Therefore it stresses the need for clear, evidencebased reasoning for spinal immobilization according to ATLS, as this is currently lacking.

The aims of this study were to investigate the correlations between Chinese version of Lumbar Stiffness Disability Index (C-LSDI) and other clinical outcomes, and to identify the factors independently affecting stiffness-related disability after long-segment fusion in patients with degenerative lumbar scoliosis (DLS). ⋯ This study showed that all HRQOLs demonstrated the varying degree of correlations with C-LSDI, of which the ODI, JOA-29, SRS-22 Function, and SF-36 PCS were most relevant, with moderate strength of associations.Moreover, longer fusion levels, higher BMI, and greater postoperative SVA independently affect C-LSDI after long segmental posterior instrumentation and fusion for DLS.
