Blunt Traumatic Vertebral Artery Injury After Cervical Fracture Dislocation: A Systematic Review of the Literature.

Certain high-energy blunt forces may produce unstable cervical fractures with or without dislocation. In rare cases where the superior facets are dislocated, however showing a significant increase within the last decade, these types of injuries may include vertebral artery entrapment at the involvement level leading to artery dissection or occlusion. This phenomenon is usually seen at the C4-C5 and C5-C6 levels of injury.

To review and evaluate multiple preoperative and postoperative sagittal parameters and their association with the risk of developing proximal junctional kyphosis (PJK) in patients with adolescent idiopathic scoliosis (AIS) who undergo correction surgery. A systematic search was performed in December 2022 in PubMed, Embase and the Cochrane Library to retrieve all the studies relevant to our research. After the study selection and data extraction following PRISMA guidelines, RevMan 5.

Incidence of vertebral artery injury in patients undergoing cervical spine trauma surgery in correlation with surgical approach: A review.

Spinal cord injuries at the cervical spine level represent the most consequential of the related injuries at all levels of the spine. They can trigger permanent unilateral or bilateral damage with conspicuous disability. Regarding unstable injuries, the gold standard approach is open reduction and osteosynthesis, which can select between anterior and posterior surgical access.

The review was conducted according to the preferred PRISMA guidelines. We conducted a literature search in the PubMed, Embase, and Cochrane Library databases.

Dysphagia as a Postoperative Complication of Anterior Cervical Discectomy and Fusion.

Anterior cervical discectomy and fusion (ACDF), despite its possible complications, remains the gold standard for the surgical treatment of patients with radiculopathy and/or myelopathy caused by cervical intervertebral disc herniation or spondylosis. Despite its high rate of incidence, postoperative dysphagia following ACDF is still poorly understood; its pathogenesis remains relatively unknown, and its risk factors are still a subject of debate. The aim of this study is to review the incidence, pathogenesis, diagnosis, and methods of prevention of dysphagia in ACDF patients.

Application of Collagen-Based Scaffolds for the Treatment of Spinal Cord Injuries in Animal Models: A Literature Update.

SCI is regarded as one of the most devastating central nervous system (CNS) injuries, exhibiting an alarmingly rising incidence rate, indirectly connected with the expansion of the global economy. The consequences of SCI are multidimensional: SCI injuries may result in permanent voluntary motor dysfunction and loss of sensation while incurring heavy economic and psychological burdens as part of the treatment. Thus, it is crucial to develop effective and suitable SCI treatment strategies.

Angiogenesis in Spinal Cord Injury: Progress and Treatment.

Traumatic spinal cord injury (SCI) provokes the onset of an intricate pathological process. Initial primary injury ruptures local micro-neuro-vascularcomplex triggering the commencement of multi-factorial secondary sequences which exert significant influence on neurological deterioration progress. Stimulating by local ischemia, neovascularization pathways emerge to provide neuroprotection and improve functional recovery.

Stem Cell Therapy for Spinal Cord Injury: A Review of Recent Clinical Trials.

Spinal cord injury (SCI) remains an incurable, life-changing neurological condition, causing permanent loss of motor and sensory function in millions of people worldwide and affecting them in every aspect of their personal and social life. In the last two decades, after its success in various fields of medicine, stem cell therapy has been investigated in the research field as a potential treatment for SCI. This review focuses on the pathophysiology of SCI, the characteristics of the different stem cell therapies used for its treatment, and the results of these therapies in recently published clinical trials.

The Role of Sclerostin in Bone Diseases.

Sclerostin has been identified as an important regulator of bone homeostasis through inhibition of the canonical Wnt-signaling pathway, and it is involved in the pathogenesis of many different skeletal diseases. Many studies have been published in the last few years regarding sclerostin's origin, regulation, and mechanism of action. The ongoing research emphasizes the potential therapeutic implications of sclerostin in many pathological conditions with or without skeletal involvement.

Vascular Injury in Elective Anterior Surgery of the Lumbar Spine: A Narrative Review.

The incidence of anterior lumbar surgery is increasing as the population is aging. Although adverse events regarding vasculature injury are uncommon, several have been described in the current literature. Complications can be categorized based on the time of occurrence, more specifically intraoperative or postoperative, but also regarding the nature of vascular damage such as thrombosis, occlusion, or rupture.

Sclerostin and Its Involvement in the Pathogenesis of Idiopathic Scoliosis.

Idiopathic scoliosis is a disorder of unknown etiology. Bone biopsies from idiopathic scoliosis patients revealed changes at cellular and molecular level. Osteocytic sclerostin is downregulated, and serum level of sclerostin is decreased.

Methylprednisolone stimulated gene expression (GILZ, MCL-1) and basal cortisol levels in multiple sclerosis patients in relapse are associated with clinical response.

Glucocorticoids (GCs) are the main treatment of relapse in multiple sclerosis (MS). Decreased sensitivity to GCs in MS patients has been associated with lack of the suppressive effect of GCs on inflammatory molecules as well as increased resistance to apoptosis. We investigated GC-sensitivity by measuring the effect of intravenous methylprednisolone (IVMP) treatment on transactivation of anti-inflammatory and apoptotic genes (GILZ, MCL-1 and NOXA respectively), in accordance to clinical outcome.

One Year Later: What Was the Impact of the COVID-19 Pandemic on Orthopedic Practice?

The coronavirus disease 2019 (COVID-19) pandemic is an enormous challenge for health care systems worldwide. Although it is widely accepted that orthopedic service has been reduced during the COVID-19 pandemic, little is known about the magnitude and qualitative characteristics of this reduction. The aim of the present study is to quantify the impact of the COVID-19 pandemic on everyday orthopedic practice and to detect the qualitative details of this impact in order to provide data for appropriate planning of health care policy.

Musculoskeletal Manifestations in Sjogren's Syndrome: An Orthopedic Point of View.

Sjogren's syndrome (SS) is a frequent entity with a broad symptomatology spectrum, mainly affecting the salivary and lachrymal glands. The disease also affects the musculoskeletal system targeting bones, specific joints, muscles, and the peripheral nerve system. Disease related clinical manifestations canhave an accumulative impact, as the syndrome is commonly associated with other rheumatic diseases.

Functional recovery following primary ACL repair with dynamic intraligamentary stabilization.

Background: Recently, a new technique, dynamic intraligamentary stabilization (DIS) was introduced for the acute repair of ACL ruptures. The purpose of this study was to report the functional recovery for patients undergoing acute anterior cruciate ligament (ACL) repair alongside DIS.

Methods: Forty five patients sustaining acute ACL rupture and treated with DIS repair were retrospectively evaluated.

Accuracy of cartilage-specific 3-Tesla 3D-DESS magnetic resonance imaging in the diagnosis of chondral lesions: comparison with knee arthroscopy.

Background: Arthroscopy is considered as "the gold standard" for the diagnosis of traumatic intraarticular knee lesions. However, recent developments in magnetic resonance imaging (MRI) now offer good opportunities for the indirect assessment of the integrity and structural changes of the knee articular cartilage. The study was to investigate whether cartilage-specific sequences on a 3-Tesla MRI provide accurate assessment for the detection of cartilage defects.

Dynamic intraligamentary stabilization and primary repair: a new concept for the treatment of knee dislocation.

Background: Traumatic knee dislocation represents a rare but devastating injury. Several controversies persist regarding type of treatment, surgical timing, graft selection, repair versus reconstruction of the medial and lateral structures, surgical techniques and postoperative rehabilitation. A new technique for primary ACL stabilization, dynamic intaligamentary stabilization (DIS) was developed at the authors' institution.
