The decision-making process concerning surgical management in basilar invagination without atlantoaxial dislocation (type B) is frequently contested. We have thus described the utilization of posterior intra-articular C1-2 facet distraction, fixation, and cantilever technique in treating type B basilar invagination, juxtaposing it against foramen magnum decompression, in this report, which also outlines the surgical results and indications for this procedure.
This retrospective, single-center cohort study was conducted. The current study encompassed fifty-four patients divided into two groups: the experimental group, undergoing intra-articular distraction, fixation, and cantilever reduction, and the control group, undergoing foramen magnum decompression. Aerobic bioreactor To assess the images radiographically, parameters such as the distance from the odontoid tip to Chamberlain's line, the clivus-canal angle, the cervicomedullary angle, the craniovertebral junction (CVJ) triangle area, the width of the subarachnoid space, and the presence or absence of syrinx were utilized. The 12-item Short Form health survey (SF-12) and Japanese Orthopedic Association (JOA) scores were used to evaluate the clinical state.
For patients assigned to the experimental group, there was a marked reduction in basilar invagination and a substantial improvement in nerve pressure relief. Following the operation, the experimental group experienced more substantial improvements in their JOA scores and SF-12 scores. Improvements in the SF-12 score exhibited a correlation with the preoperative CVJ triangle area (Pearson correlation, r = 0.515; p = 0.0004). A 200 cm² cut-off was determined as the indicator for surgical intervention using our technique. No severe complications, nor any infections, occurred.
An effective treatment for type B basilar invagination is the posterior intra-articular C1-2 facet distraction, fixation, and cantilever reduction technique. Muscle biopsies Given the multiplicity of factors at play, further therapeutic approaches warrant exploration.
To effectively address type B basilar invagination, the posterior intra-articular C1-2 facet distraction, fixation, and cantilever reduction method is utilized. Given the diverse elements at play, alternative treatment methods deserve consideration.
Evaluating the initial radiographic and clinical effectiveness of uniplanar versus biplanar expandable interbody cages in single-level minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).
Previous 1-level MIS-TLIF surgeries, utilizing uniplanar and biplanar polyetheretherketone cages, were examined in a retrospective review. Radiographs acquired prior to surgery, at six weeks post-procedure, and at twelve months post-procedure were evaluated using radiographic measurement techniques. The Oswestry Disability Index (ODI) and visual analogue scale (VAS) were employed for back and leg pain assessment at both 3-month and 1-year follow-ups.
In total, 93 patients were selected for inclusion, with 41 displaying uniplanar characteristics and 52 exhibiting biplanar characteristics. Improvements in anterior disc height, posterior disc height, and segmental lordosis were substantial in both cage types, assessed one year post-operatively. Results from a study on cage subsidence at the six-week mark showed no appreciable differences between the uniplanar (219%) and biplanar (327%) devices (odds ratio, 2015; 95% confidence interval, 0651-6235; p = 0249), and no additional subsidence occurred within the following year. Between-group comparisons revealed no statistically meaningful differences in the magnitude of improvement, as evaluated by ODI, VAS back, or VAS leg measurements, at the 3-month and 1-year follow-up stages. The proportion of patients achieving a minimal clinically significant improvement on ODI, VAS back, or VAS leg at the 1-year mark did not show statistically appreciable disparities between treatment groups (p > 0.05). Importantly, a comparison across groups showed no statistically significant differences in complication rates (p = 0.283), 90-day readmission rates (p = 1.00), rates of revisional surgical procedures (p = 0.423), or one-year fusion rates (p = 0.457).
Anterior and posterior disc height, segmental lordosis, and patient-reported outcome measures demonstrate significant improvement at one year postoperatively, thanks to the utilization of safe and effective expandable biplanar and uniplanar cages. The groups exhibited no significant disparities in radiographic outcomes, subsidence rates, average subsidence distance, one-year patient-reported outcomes, or postoperative complications.
Expandable cages, both biplanar and uniplanar, are demonstrably effective in restoring anterior and posterior disc height, bolstering segmental lordosis, and ultimately improving patient-reported results within the first post-operative year. No significant differences were found in the radiographic outcomes, subsidence rates, mean subsidence distance, 1-year patient-reported outcomes, and postoperative complications between the groups.
Lumbar lateral interbody fusion (LLIF) facilitates the strategic placement of sizable interbody cages, preserving the crucial ligamentous structures vital for spinal stability. Research involving both clinical and biomechanical aspects has shown that stand-alone LLIF is a viable treatment for single-level spinal fusions. A comparative study was conducted on the stability of 4-level, standalone LLIF using 26mm-wide cages and bilateral pedicle screw/rod fixation.
Eight human cadaver specimens, including L1 through L5, were a part of the investigation. A universal testing machine (MTS 30/G) had specimens affixed to it. To induce flexion, extension, and lateral bending, a 200-newton load was applied at a pace of 2 millimeters per second. Axial rotation was executed on 8 specimens at the rate of 2 revolutions per second. An optical motion-tracking device was employed to record the three-dimensional movement of the specimen. Specimens underwent testing in four conditions: (1) no surgical intervention, (2) installation of bilateral pedicle screws and rods, (3) execution of a 26-mm stand-alone lumbar lateral interbody fusion, and (4) execution of a 26-mm lumbar lateral interbody fusion with the concurrent addition of bilateral pedicle screws and rods.
Using bilateral pedicle screws and rods, compared to a standalone LLIF, resulted in a 47% decrease in flexion-extension range of motion (p < 0.0001), a 21% decrease in lateral bending (p < 0.005), and a 20% decrease in axial rotation (p = 0.01). Adding bilateral posterior instrumentation to stand-alone LLIF procedures yielded significant decreases in three-planar motion: a 61% reduction in flexion-extension (p < 0.0001), 57% in lateral bending (p < 0.0001), and 22% in axial rotation (p = 0.0002).
In spite of the biomechanical benefits offered by the lateral approach and 26 mm wide fusion cages, a stand-alone LLIF approach for four-level spinal fusion does not provide the same level of support as pedicle screws and supporting rods.
Even with the potential biomechanical benefit of the lateral approach using 26 mm wide cages, stand-alone LLIF for 4-level spinal fusion is not comparable to the support provided by pedicle screws and rods.
Within the last twenty years, spinal sagittal alignment and equilibrium have become a crucial focus in the practice of spine surgery. Studies now underscore the significance of sagittal balance and alignment for better health-related quality of life. To accurately diagnose and treat adult spinal deformity (ASD), a thorough understanding of normal and abnormal spinal sagittal alignment is essential. This discussion will cover the prevalent ASD classification, crucial sagittal alignment parameters for diagnosis, compensatory adaptations for maintaining spinal balance, and the link between sagittal alignment and clinical symptoms.
