However, no studies have systematically summarized the impacts of HOA on ASD patients, either radiologically or clinically./r/nTo compare the spinal sagittal alignment parameters pre- […]

There has been increasing interest in associations between paraspinal muscle phenotypes and common spinal disorders, including lumbar spinal stenosis (LSS). However, the relation of paraspinal muscle morphology and composition with LSS is unclear./r/nTo provide a systematic overview and synthesis […]

Cervical Disc Arthroplasty (CDA) treats cervical disc degeneration while preserving spinal mobility. Although effective, the procedure poses a risk to the Vertebral Artery (VA), which transverses the foramina of C2-C6 and enters the skull via the foramen magnum. While the vertebral artery injury […]

A 67-year-old male was treated with ampicillin for infective endocarditis and lumbar pyogenic spondylitis caused by Enterococcus fecalis. The patient was switched to the antibacterial drug teicoplanin because of ampicillin-induced tubulointerstitial nephritis, and fever and skin rash were observed […]

Cerebral air embolism (CAE) is a rare but catastrophic complication of percutaneous kyphoplasty (PKP), with only 6 documented cases in spinal surgery literature. This study presents a novel case of CAE following PKP, resulting in a vegetative state despite hyperbaric oxygen therapy (HBOT), and […]

A 66-year-old woman with locally advanced lung adenocarcinoma underwent FDG-PET/CT, which revealed superior vena cava invasion and thrombosis of the brachiocephalic veins. Tracer injection on the side of thrombosis demonstrated hypermetabolism in the dorsal spine, likely due to collateral venous […]

The ketogenic diet (KD) is a dietary regimen characterized by high-fat, moderate-protein, and extremely low-carbohydrate intake. While clinically established as an effective therapy for epilepsy and various metabolic and neurological disorders, its application presents unique challenges in surgical […]

Psoas abscesses are infrequent yet significant conditions characterized by the localized accumulation of purulent material within the psoas muscle compartment, often resulting in debilitating pain localized to the hip, low back, or groin. Clinical symptoms typically include pain, fever, and […]

For patients with ankylosing spondylitis (AS) who experience inefficacy or adverse events with biologics, no recommendations exist regarding the preference for class cycling or switching as a second- or higher-line biologics. Previous studies on the drug retention of TNF and IL-17 inhibitors in AS […]

Postmenopausal estrogen deficiency accelerates bone mineral density (BMD) decline, significantly elevating the risk of osteoporotic fractures. Choline, a vital nutrient involved in lipid homeostasis and inflammatory pathways, has been associated with skeletal health. Yet its role in preserving bone […]

Spondyloarthritis (SpA) encompasses a group of chronic inflammatory diseases affecting the spine and peripheral joints. Although classification criteria for SpA have been tested globally, their validity and performance in Latin American (LA) populations remain debated./r/nA systematic literature […]

Uveitis is a common extra-articular manifestation of ankylosing spondylitis (AS), and a systematic analysis of the effects of biologics on new-onset and recurrent uveitis is clinically important./r/nWe conducted a network meta-analysis (NMA) to assess the impact of anti-TNF-α (adalimumab, […]

Cervical spondylotic myelopathy (CSM) is the most prevalent spinal cord impairment among adults, primarily due to age-related degenerative changes. Although surgical interventions are commonly recommended for severe cases, the optimal timing and procedural complexities remain controversial. […]

Diffuse idiopathic skeletal hyperostosis (DISH) is a non-inflammatory arthritis characterized by bridging ossification along the anterolateral spine. Bridging osteophytes in DISH can result in fusion, altering the biomechanics and increasing the risk of unstable spinal fractures. This report […]

Decapitation resulting from hanging is an infrequent phenomenon, often influenced by multiple biomechanical factors. We report a case of a 72-year-old male who committed suicide by hanging, leading to complete decapitation. The drop height was approximately 10.668 m, with a static nylon rope of […]

Spinal deformities represent a major public health concern, characterized by abnormal curvature and alignment of the spine. We aimed to investigate the alterations in pelvic, trunk, and upper limb biomechanics during walking in individuals with spinal deformities compared to healthy controls./r/nWe […]

Pedicle screw internal fixation is a significant method for maintaining spinal stability. Despite the existence of numerous systematic reviews and meta-analyses that have evaluated the efficacy and safety of robotic-assisted compared to freehand technique, a comprehensive evaluation of the […]

This study explores the use of augmented reality (AR) for intraoperative guidance during the microsurgical resection of diffuse gliomas, especially those located near the critical corticospinal tract. AR provides surgeons with a three-dimensional view of essential brain structures in real time, […]

Catastrophic Surgical Complications of Not Pre-Treating Osteoporosis - John Dimar II, MD

Surgical Management of Spine Metastases with Carbon Fiber Implants - Miki Katzir, M.D.

BackgroundChronic spinal pain (CSP) is a major global health challenge. Virtual reality-based training (VRBT) shows promise as a complementary intervention for exercise therapy (ET).ObjectiveThis review aimed to provide conclusive evidence on the effectiveness of ET with and without the […]

Position changes in patients with thoracic spinal stab wounds may cause displacement of embedded sharp objects, increasing the risk of spinal cord or surrounding tissue injury. Management of these cases under anesthesia requires a carefully planned approach to minimize movement and ensure patient […]

Although instrumented fusion is the most widely accepted surgical treatment for adolescent idiopathic scoliosis, it leads to permanent spinal motion loss and an increased risk of adjacent segment degeneration. Consequently, there is great interest in finding nonfusion methods to correct scoliosis […]

We compared the efficacy of romosozumab and denosumab in elderly women with primary osteoporosis and knee osteoarthritis in a randomized controlled trial. A total of 112 participants aged 75-90 years were randomized equally into the romosozumab and denosumab groups. Among these, 49 and 52 […]

Paragangliomas are rare neuroendocrine tumors that can manifest with endocrinological symptoms from excessive catecholamine secretion and symptoms from mass effect depending on biochemical behavior and tumor location./r/nFollowing an encounter with a patient with a rare case of paraganglioma of the […]

A healthy 15-year-old male athlete presented with upper thoracic congenital kyphoscoliosis, causing notable pain and limiting participation in competitive sports.
