A new instrumentation for posterior spinal surgery consists of metallic rods carved with diamond-shaped asperities on which vertebral hooks or screws can be screwed in any position, level, or degree of rotation. The rods are interlocked by means of devices for transverse traction (DTTs), rectangular constructs with multiple vertebral grips, the stability of which allows suppression of any postoperative external support. Initially designed to treat scoliosis, this instrumentation design allows mobilization of the vertebrae located at the apex of the curve and obtains a three-dimensional correction. Correction of the areas of the most important structural deformation can also be obtained at the level of the end vertebrae, without any need to resort to an important distraction force. The technique varies according to the various types of curvatures. Approximately 250 patients were operated upon from 1983 to 1985. In idiopathic scoliotic curvatures, the mean percentage of correction was 66%. An important improvement of the associated sagittal deformations and of the apical derotation was observed in flexible curves. In paralytic curves, particularly with a pelvic obliquity, the percentage of correction of the frontal deformation is 77%. All of the spine patients were ambulatory in the first postoperative week, without any external support, and returned to their school or family activities. In 43 patients with follow-up periods longer than two years, there were no technical errors in 38. The final angular loss of correction was less than 2 degrees in the error-free group.

Background And Objectives: Three-column osteotomy (3CO) offers substantial spinal deformity correction. Thoracic neurovascular bundle sacrifice is often required, and anterior spinal artery (ASA) perfusion can be compromised. Spinal angiography allows localization of variable ASA vascular contribution.

This study aims to explore the relationship between the gut microbiome, serum metabolome, and FR in chronic LBP patients.
Methods: Serum metabolomic profiling and gut microbiome analysis were conducted in chronic LBP patients with and without FR (LBP + FR, = 40; LBP, = 40) and Healthy Controls (HC, = 31).

This case report describes a 70-year-old male presenting with limb weakness, urinary retention and tandem cervical and lumbar spinal stenosis with complicating white cord syndrome, a rare reperfusion injury post decompression surgery. Initially admitted following an unwitnessed fall, the patient's neurological examination indicated that progressive weakness of the limbs and sensory loss etiology is cervical and lumbar spondylosis with severe spinal canal stenosis, confirmed by imaging. Due to rapid deterioration, he underwent C5 corpectomy, cervical decompression and fusion.

Study Design: Subgroup analysis of a retrospective clinical and animal trial [Study of different doses of methylprednisolone on functional recovery of spinal cord injury].
Objective: The aimed to investigate the efficacy of low-dose methylprednisolone regimens in promoting neural repair after SCI.
Summary Of Background Data: Spinal cord injury (SCI) can result in sensory, motor, and autonomic nerve dysfunction, often leading to disability or death.

Study Design: Retrospective observational study.
Objective: To evaluate whether the combined American Spine Registry and Medicare (ASR/CMS) data yields substantially different findings versus ASR data alone with regard to key parameters such as risk stratification, complication rates and readmission rates in lumbar surgery investigated through an analysis of 8,755 spondylolisthesis cases.
Summary Of Background Data: Medicare data correlation has been effective for determining revision rates for other procedures such as total hip replacement.
