BACKGROUND: Axis (C2) screw fixation has been shown to be effective in treating disorders that necessitate cervical stabilization. Although translaminar C2 screws have demonstrated clinical efficacy in adults, this technique has not yet been thoroughly investigated in children. This study describes the indications, technique, and results of translaminar C2 screw fixation in a case series of pediatric cervical spine disorders. METHODS: We searched the orthopaedic database at our institution for patients who had undergone a cervical spinal fusion that encompassed C2 between 2007 and 2017...

Spinal epidural hematoma (SEH) is a rare cause of nerve root or cord compression; its pathogenesis is not always clearly recognizable. The aim of this paper was to investigate possible etiopathological factors in a consecutive series of patients affected by traumatic SEH treated at our institution. Seven patients with neurologic impairment due to traumatic SEH were retrospectively analyzed after diagnosis and surgical treatment. Thoracic localization was found in 5 cases, and lumbar and cervical localization were found in 1 patient each...

BACKGROUND: Evidence-based medicine is the application of research findings to inform individual clinical decisions. There is a tension-both philosophical and practical-between the average result from a population study and the circumstances and needs of an individual patient. This personal account of "evidence-based" trauma care illustrates and explores this tension. THE CASE: The author, a keen athlete, describes her experience of a high-impact cycle accident that led to limb fractures (which were diagnosed and treated according to evidence-based guidelines) and also an occult injury to the cervical spine (which was not diagnosed at the time)...

INTRODUCTION: Occipital condyle fractures (OCFs) have previously been described based upon anatomic characteristics; however, recent literature has proposed management based on biomechanical stability and neural element compression. The treatment of biomechanically stable fractures varies between observation and cervical immobilization. Prior to determining best management, understanding of concomitant cervical spine fractures in the presence of OCFs is prudent. The primary aim of this pilot study was to determine the rate of occurrence of biomechanically significant cervical spine fractures with OCFs...

This surgical technical case report presents initial clinical experience and preliminary results with a less invasive surgical solution for selected hangman's fracture. A well-known stabilization technique (i.e. direct transpedicular osteosynthesis) was applied through a minimally invasive small incision transmuscular posterior approach guided by a standard C-arm fluoroscopy. This mini-open approach to C2 vertebra allows similar dissection, visualization of the bony landmarks, visual control of the transpedicular screw path drilling, tapping and screw insertion to the standard posterior cervical spine approach...

OBJECTIVE: Fixation with the axis vertebra (C2) using pedicle screws is commonly used to treat an unstable occipitocervical junction; however, it is accompanied by a risk of vertebral artery injury. The occiput-C2 (OC2) crossing translaminar screw fixation technique may avoid this risk, but rod implantation is difficult. Offset connectors can help facilitate this construct. This study aimed to evaluate the stability of a technique for OC2 crossing translaminar screw fixation using offset connectors (C2LAM + OF) in comparison with other methods...

Traumatic cervical facet dislocation (CFD) is often associated with devastating spinal cord injury. Facet fractures commonly occur during CFD, yet quantitative measures of facet deflection, strain, stiffness and failure load have not been reported. The aim of this study was to determine the mechanical response of the subaxial cervical facets when loaded in directions thought to be associated with traumatic bilateral CFD - anterior shear and flexion. Thirty-one functional spinal units (6 × C2/3, C3/4, C4/5, and C6/7, 7 × C5/6) were dissected from fourteen human cadaver cervical spines (mean donor age 69 years, range 48-92; eight male)...

Fractures of the C1 vertebrae (atlas) are commonly the result of falls and other trauma, which cause hyperextension, or axial compression of the cervical spine. Although historically thought as a benign injury with lower neurological risks, current data suggests that this may not hold true for geriatric patients (aged 65 y and older) who may be predisposed to these fractures even after lower-energy trauma such as ground-level falls. Advancements in orthopedic trauma care has increased our diagnostic abilities to identify and manage patients with C1 fractures and other upper cervical spine trauma...

BACKGROUND: The Abbreviated Injury Scale (AIS) is an internationally accepted coding system created by the Association for the Advancement of Automotive Medicine, utilized to code traumatic injuries as a function of severity, the latter often defined as mortality risk. Periodic reassessment of that risk is prudent, in light of advances in health care and relationship of nonanatomic factors to death. OBJECTIVE: The objective of this study was to reevaluate the risk of death associated with spine fractures with and without neurologic deficit, age factors associated with it, and the impact of hospital coding on the accuracy of these efforts...

PURPOSE: The classification systems by Anderson and D'Alonzo, Effendi, Benzel and others have limitations when it comes to morphologically categorising fractures of the second cervical vertebral body (C2) that present with or without an additional fracture of the dens or with or without an extension of the fracture line into the vertebral arch and displacement. Currently, there are no definitive recommendations for the treatment of fractures at the junction of the dens with the vertebral body of C2 on the basis of outcome and stability data...

BACKGROUND: Skeletal and soft tissue damage are often associated with unilateral facet dislocations, which undoubtedly lead to instability of the spine and further increase difficulties in cervical reduction. This type of irreducible facet dislocation is usually accompanied with potential catastrophic consequences including neurological deficit and severe disability. Therefore, a consistent and evidence-based treatment plan is imperative. CASE PRESENTATION: The literature regarding the management of traumatic unilateral locked cervical facet dislocations was reviewed...

INTRODUCTION: In recent years, delivery of cost-effective "essential neurosurgery" in resource-limited communities has been recognized as an indispensable part of health care and a global health priority. The purpose of this study was to review outcomes from operative management of spine trauma at a resource limited government hospital in Phnom Penh, Cambodia, and to provide an epidemiologic report to guide prevention programs. METHODS: A retrospective review of a prospective neurosurgical database was performed to identify risk factors for spine trauma and severe spinal cord injury (ASIA A or ASIA B) and to evaluate the cost-effectiveness of surgery for patients treated at Preah Kossamak Hospital for subaxial and thoracolumbar spine trauma from 2013 to 2016...

Vertebral fractures commonly occur at the thoracolumbar junction. These fractures can be treated with mild residual deformity in many cases, but are reportedly associated with increased risk of secondary vertebral fractures. In the present study, a three-dimensional (3D) whole spine model was constructed using the finite element method to explore the mechanism of development of compression fractures. The 3D model of the whole spine, from the cervical spine to the pelvis, was constructed from computed tomography (CT) images of an adult male...
