Periostin, an extracellular matrix protein, is widely expressed in a variety of tissues and cells. It has many biological functions and is related to many diseases: for example, it promotes cell proliferation and differentiation in osteoblasts, which are closely related to osteoporosis, and mediates cell senescence and apoptosis in chondrocytes, which are involved in osteoarthritis. Furthermore, it also plays an important role in mediating inflammation and reconstruction during bronchial asthma, as well as in promoting bone development, reconstruction, repair, and strength. Therefore, periostin has been explored as a potential biomarker for various diseases. Recently, periostin has also been found to be expressed in intervertebral disc cells as a component of the intervertebral extracellular matrix, and to play a crucial role in the maintenance and degeneration of intervertebral discs. This article reviews the biological role of periostin in bone marrow-derived mesenchymal stem cells, osteoblasts, osteoclasts, chondrocytes, and annulus fibrosus and nucleus pulposus cells, which are closely related to spinal degenerative diseases. The study of its pathophysiological effects is of great significance for the diagnosis and treatment of spinal degeneration, although additional studies are needed.

Open-Door Cervical Laminoplasty Using Instrumentation of Every Level Versus Alternate Levels: A Multicenter, Randomized Controlled Trial.
J Bone Joint Surg Am
January 2025
Department of Orthopedics, Osaka Metropolitan University Graduate School of Medicine, Osaka, Japan.
Background: In the setting of cervical open-door laminoplasty, the question of whether or not every opened laminar level should be instrumented has not been sufficiently investigated. We postulated that the surgical outcomes of open-door laminoplasty with instrumentation of every second opened level (skip-fixation) might not be inferior to those of laminoplasty with instrumentation of every opened level (all-fixation). The purpose of the present study was to test the noninferiority of laminoplasty with skip-fixation in improving myelopathy at 2 years postoperatively compared with all-fixation.

An 11-year-old male Bengal tiger () was referred for a 2-week history of ambulatory tetraparesis, generalized ataxia, and hypermetric gait, associated with mild right head tilt and spontaneous proprioceptive deficit on the right forelimb. Neuroanatomical localization was C1-C5 myelopathy; cerebellum-vestibular system involvement was also considered. Hematology and serum biochemistry were unremarkable, although serum vitamin A (0.

Objectives: Patients suffering from chronic pain use online platforms, such as Reddit, to engage in personal exchanges while maintaining anonymity. Analysis of comments and questions posted on these online forums provide unique insight into conversations that patients may be having outside of the physician's office regarding pain-relief procedures, specifically radiofrequency ablation (RFA).
Materials And Methods: Using the Python Reddit Application Programming Interface Wrapper, we identified and screened Reddit users' posts.
Additional dorsal interspinous stabilisation has no advantage after decompression of degenerative lumbar spinal stenosis.
Brain Spine
December 2024
Medical University of Greifswald, Department of Orthopaedics, Greifswald, Germany.
Introduction: Interspinous devices are an alternative to instrumented fusion for the treatment of lumbar spinal stenosis (LSS) with radiological instability or deformity. The devices claim to improve clinical symptoms by indirect foraminal decompression with fewer complications and similar functional outcomes compared to conventional fusion techniques, and by avoiding a (further) deterioration of the anatomy of the spine while being less invasive than instrumented fusion.
Research Question: Do interspinous devices provide a benefit in combination with a decompression of degenerative LSS?
Material And Methods: In this observational study, 117 patients were treated by decompression surgery alone (n = 37), decompression plus instrumented spinal screw fixation and anterior cage support (n = 41) or decompression plus stabilisation with interspinous devices (n = 39).
Friedreich Ataxia: An (Almost) 30-Year History After Gene Discovery.

Department of Neurology and Neurosurgery, McGill University, Montreal, Canada.
In the late 1800s, Nikolaus Friedreich first described "degenerative atrophy of the posterior columns of the spinal cord," noting its connection to progressive ataxia, sensory loss, and muscle weakness, now recognized as Friedreich ataxia (FRDA). Renewed interest in the disease in the 1970s and 80s by the Quebec Cooperative Group and by Anita Harding led to the development of clinical diagnostic criteria and insights into associated biochemical abnormalities, although the primary defect remained unknown. In 1988, Susan Chamberlain mapped FRDA's location on chromosome 9.
