Giant Cell Tumor of Distal Radius Treated with Wide Local Excision and Reconstruction with Ipsilateral Proximal Fibular Autograft - A Follow-Up.

Introduction: Giant cell tumour or osteoclastoma is benign, locally aggressive tumor with bone destruction and with malignant potential. It accounts for 5% of all primary bone tumor and occurs in skeletally mature individuals in the age group of 30 to 45 with peak incidence in the 3rd decade. GCT is more common in females.

Minimally Invasive Versus Open Spinal Fusion Surgery for Spondylolisthesis Treatment.

Background: In recent years, there has been a growing utilization of minimally invasive (MI) techniques, which provide the potential advantages of minimizing surgical stress, post-operative pain, and hospitalization duration. Nevertheless, the existing body of literature primarily comprises of studies conducted at a single medical site, which are of low quality and lack a comprehensive analysis of treatment techniques exclusively focused on spondylolisthesis. We conducted this systematic review and meta-analysis to compare minimally invasive surgery (MIS) and open surgery (OS) spinal fusion outcomes for the treatment of spondylolisthesis.

MIS transoral technique for C1-C2 cord compression - Intricacies using a 360⁰ navigated approach.

Introduction: Surgeries in the occipitocervical and upper cervical region are always quite challenging and need adequate surgical experience and expertise. Especially in cases, where both anterior and posterior surgical access is required, complication rates could be significantly high. The transoral approach for the ventral pathologies of the upper cervical region has been previously described using the conventional open technique where post-operative morbidity is a concern.

Preoperative Predictors of Soft Tissue Releases Required for Femoral Exposure in Direct Anterior Total Hip Arthroplasty.

Background: Sequential soft tissue releases are utilized in direct anterior approach (DAA) total hip arthroplasty (THA) as incomplete femoral exposure may lead to complications. This study identifies patient-specific parameters associated with soft tissue releases required for femoral exposure.

Methods: A retrospective review was conducted on 133 patients (150 hips) who underwent primary THA via DAA with a single surgeon.

A Novel Dynamic Growth Rod Inducing Spinal Growth Modulation for the Correction of Spinal Deformities.

Background: Growth rods are the gold standard for treating early-onset scoliosis (EOS). However, current treatments with growth rods do not optimize spinal growth in EOS patients, and frequent distraction surgeries significantly increase complications, imposing considerable economic and psychological burdens on patients. An improved growth rod is urgently required to address the need for dynamic growth and external regulation.

Intradural extra-medullary spinal cord tumor after dorso-lumbar spine fixation following 12th dorsal vertebra burst fracture: A case report with literature review.

Intradural extramedullary spinal cord tumors are rare but can cause significant neurological symptoms. We present a case of a 23-year-old male who developed progressive bilateral leg pain and lower limb weakness 2 years after undergoing posterior spinal fixation for a T12 burst fracture. Magnetic resonance imaging (MRI) revealed an intradural extramedullary tumor at the site of the previous surgery.

Astragaloside IV Relieves Central Sensitization by Regulating Astrocytic ROS/NF-κB Nuclear Translocation Signaling in Chronic Migraine Male Rats.

Chronic migraine (CM) is a disabling neurological disease. Astragaloside IV (AS-IV), a natural product derived from Astragalus membranaceus, shows great potential in treating chronic pain by relieving inflammation and oxidative stress. This study aimed to investigate the effects and mechanisms of action of AS-IV on CM.

mHealth-Augmented Care for Reducing Depression Symptom Severity Among Patients With Chronic Pain: Exploratory, Retrospective Cohort Study.

Background: Depression and chronic pain are commonly comorbid, mutually reinforcing, and debilitating. Emerging approaches to mobile behavioral health care (mHealth) promise to improve outcomes for patients with comorbid depression and chronic pain by integrating with existing care models to bolster support and continuity between clinical visits; however, the evidence base supporting the use of mHealth to augment care for this patient population is limited.

Objective: To develop an evidence base that sets the stage for future research, we aimed to explore the associations between changes in depression severity and various integrated care models, with and without mHealth augmentation, among patients with comorbid depression and nonmalignant chronic pain.

A guide to CNN-based dense segmentation of neuronal EM images.

Large-scale reconstitution of neuronal circuits from volumetric electron microscopy images is a remarkable research goal in neuroanatomy. However, the large-scale reconstruction is a result of automatic segmentation using convolutional neural networks (CNNs), which is still challenging for general researchers to perform. This review focuses on two representative CNNs for dense neuronal segmentation: flood-filling networks (FFN) and local shape descriptors (LSD)-predicting U-Net (LSD network).

Regulation of Dendrite and Dendritic Spine Formation by TCF20.

Mutations in the Transcription Factor 20 (TCF20) have been identified in patients with autism spectrum disorders (ASDs), intellectual disabilities (IDs), and other neurological issues. Recently, a new syndrome called TCF20-associated neurodevelopmental disorders (TAND) has been described, with specific clinical features. While TCF20's role in the neurogenesis of mouse embryos has been reported, little is known about its molecular function in neurons.

Editorial: Precision Medicine in Spinal Oncology.

This special focus issue from the 2023-2024 AOSpine Knowledge Forum Tumor represents a culmination of years of experience devoted to advancing the care of patients with both metastatic and primary spinal tumors. We have learned much since the fundamental assessments of instability that led to the Spinal Instability Neoplastic Score (SINS), the grading of epidural disease utilizing the Epidural Spinal Cord Compression Scale (aka Bilsky grade), as well as the development of tumor-specific health related quality of life assessments such as the Spine Oncology Study Group Outcome Questionnaire (SOSGOQ). These tools have enabled us to make several prior recommendations for the appropriate use of advanced surgical techniques such as en bloc resection and the use of stereotactic body radiotherapy (SBRT) to optimize patient care.

Long-Term Efficacy and Safety of Denosumab: Insights beyond 10 Years of Use.

Osteoporosis management in post-menopausal women focuses on fracture prevention, with denosumab as a key therapeutic option. Despite its proven efficacy in reducing fracture risk and increasing bone mineral density (BMD) over 10 years, its long-term impact remains uncertain. We evaluated the literature on its efficacy and safety beyond the initial decade.

"Excluding Myself From What I Need the Most": Experiences of Loneliness in People With Inflammatory Arthritis: A Qualitative Study.

Objective: Despite advancements in pharmacological treatments, living with inflammatory arthritis (IA) (including rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA)) can make it challenging to engage in social activities, which may increase the risk of loneliness. Although loneliness is predominantly prevalent in IA, its origin and impact on mental health status on daily life with IA remain unexplored. Therefore, the objective of this study was to describe the experiences of people with IA in relation to loneliness.
