To development a nomogram based on clinical features and apparent diffusion coefficient (ADC) of the cervical spinal cord in surgical prognosis in patients with cervical spondylotic myelopathy (CSM). Patients with CSM who underwent decompression surgery between March and September 2023 were enrolled. Patients underwent conventional cervical spine MRI and sagittal position ZOOM...
The aim of this study was to evaluate bony fusion with Low Dose CT (LDCT) over time following posterior scoliosis surgery in an all screw construct in patients with AIS with special focus on whether the spinal fusion process continue to develop beyond 2 years after scoliosis surgery and to evaluate if LDCT is an adequate radiological method to assess fusion maturation. Twenty...
The present study aimed to analyze the preoperative degeneration of the sacroiliac joint (SIJ) and its involvement in postoperative pelvic incidence (PI) change. Data from consecutive patients who underwent corrective surgery for adult spinal deformity (ASD) were included in this study. Pre- and early postoperative full-standing radiographs and preoperative pelvic computed...
Pyogenic spondylodiscitis is a significant health concern, particularly in older individuals. Minimally invasive surgical techniques, such as posterior fixation, are promising for infection control; however, their mechanisms remain unclear. This study aimed to clarify how posterior fixation promotes infection control in an animal model. Thirty female Wistar rats were used to...
Spondylodiscitis is a serious condition requiring prolonged antibiotic therapy. Relevant pharmacokinetic tissue understanding of antibiotics in a spondylodiscitis setting is limited. The study aimed to investigate cefuroxime concentrations in the L4/L5 intervertebral disc, lumbar bone, paravertebral muscle and subcutaneous tissue using microdialysis. Eight pigs received 1,500 mg...
To report all complications that occurred during the 2 to 5-year postoperative period, describe reoperations during this time period, and compare patients who did and did not have major, surgery-related complications and/or reoperations during this time period. The Scoli-RISK-1 study enrolled 272 ASD patients undergoing surgery from 15 centers. Inclusion criteria were Cobb angle...
To analyze the evolution of chronic neck and low back pain prevalence in the general Spanish population (≥ 15 years) from 2006 to 2020, examining differences by sex, age, social class, and the potential influence of the COVID-19 pandemic. A repeated cross-sectional observational study was conducted based on data from six health surveys conducted in Spain between 2006 and 2020...
En-bloc spondylectomy in the lumbar spine is a challenging procedure mainly due to a complex prevertebral anatomy. The aim of our study is to describe the anatomy of the diaphragmatic crura and surrounding vascular and neural structures which may be iatrogenically injured during the surgical resection. Ten embalmed specimens were meticulously dissected. Widths of the...
A biopsychosocial assessment of a person with low back pain (LBP) should include the detection of psychological risk factors. Pragmatically, clinicians often use their clinical impression rather than questionnaires to screen for psychological risk factors. This scoping review explores how accurately depression, anxiety, and psychological distress can be identified by...
Prehabilitation before spinal surgery may enhance patients’ ability to withstand physical and mental stress during the perioperative period. It has the potential to reduce complications, accelerate recovery, and deliver sustainable, patient-relevant improvements. However, high-quality evidence remains limited, and it is unclear which prehabilitation concepts, training protocols...
Intervertebral disc degeneration (IVD) is a leading cause of low back pain, a prevalent musculoskeletal condition. IVD degeneration is characterized by the degradation of nucleus pulposus (NP), annulus fibrosus (AF), and cartilage endplates (EP). Growth Differentiation Factor 6 (GDF6), part of the bone morphogenetic protein family, has demonstrated potential in maintaining disc...
To evaluate the accuracy of opportunistic measurements of volumetric bone mineral density (vBMD) in intraoperative multi-detector CT (MDCT) scans, using preoperative MDCT as the reference. This retrospective, single-center study included 105 patients (mean age: 73 ± 12.6 years, 53 women) who underwent spine surgery for various indications. All patients had preoperative MDCT with...
During full flexion of the spine, the paraspinal muscles are largely inactive. This suggests that passive structures like the posterior osteoligamentous complex (POLC), consisting of interspinous and supraspinous ligaments and the spinous processes, play a key role in spinal stability and protection of the spinal column. The POLC, however, is often resected or damaged during...
Lateral Lumbar Interbody Fusion (LLIF) has become a minimally invasive procedure for treating degenerative lumbar conditions. While it offers reduced blood loss and faster recovery, patient satisfaction following LLIF surgery shows significant variability. Identifying the factors influencing satisfaction is crucial for optimizing surgical outcomes and improving patient care. This...
Cervical pedicle screw (CPS) instrumentation offers significant biomechanical advantages compared to lateral mass or transarticular fixation. Nonetheless, malpositioning complications constitute a relevant concern. Customized patient-specific 3D-printed templates have been developed to improve CPS placement accuracy and safety. The aim of this study is to present our experience...
This study was designed to develop a machine learning (ML) model that predicts future Cobb angle in patients with adolescent idiopathic scoliosis (AIS) using minimal radiographs and simple questionnaires during the first and second visits. Our study focused on 887 female patients with AIS who were initially consulted at a specialized scoliosis center from July 2011 to February...
Basilar invagination (BI) represents a complex anomaly of the craniovertebral junction, characterized by the displacement of the odontoid process towards the foramen magnum. Current surgical interventions include anterior decompression and combined anterior-posterior decompression with posterior fusion. Traditional methods for odontoid resection encompass transoral, transnasal...
Thoracolumbar kyphosis (TLK) is frequently reported in children with achondroplasia. The combination of TLK and the narrow spinal canal in achondroplasia increases the risk of developing symptomatic spinal stenosis. However, there is no consensus on the optimal management of TLK. This retrospective cohort study evaluated children under four years old with achondroplasia...
Lumbar spinal stenosis (LSS) is a frequently occurring condition defined by narrowing of the spinal or nerve root canal due to degenerative changes. Physicians use MRI scans to determine the severity of stenosis, occasionally complementing it with X-ray or CT scans during the diagnostic work-up. However, manual grading of stenosis is time-consuming and induces inter-reader...
The surprising increase observed in recent years in the use of minimally invasive sacroiliac joint arthrodesis techniques as a treatment for low back pain justifies an objective review of this results. carry out a systematic review of the literature to evaluate the clinical results of patients with low back pain treated with percutaneous arthrodesis of the SIJ. Systematic review...
To explore the efficacy and safety of the direct inferior endplate approach in percutaneous endoscopic interlaminar discectomy (PEID) for the treatment of L5-S1 disc herniation. This was a retrospective analysis of 116 patients with L5-S1 disc herniation treated with PEID; 74 patients underwent surgery via the direct inferior endplate approach (group A), and 42 patients underwent...
Disruptions in global sagittal spinal alignment can lead to changes in global sagittal spinal alignment, often manifesting as sagittal malalignment, where the trunk shifts forward. We proposed that these alignment changes are linked to degenerative lumbar spondylolisthesis (DS). The objective was to assess global spinal alignment in low-grade DS using sagittal vertical axis (SVA...
