MOLECULAR MECHANISMS REGULATING SPINE REMODELLING
… synaptic plasticity and dendritic spine remodeling. Recent studies have shown that N-Cadherin can be cleaved by the metalloproteinase ADAM10. Here we demonstrate that modulating ADAM10 localization and activity at synaptic sites regulates its processing of N-Cadherin. This indices …

Tubercular disease of the spine
… typical examples of tuberculous disease of the spine. Only those suitable for fixation operation are treated in a general hospital. Thus the cases are of adolescents and. adults. The special points to be noted in them are: -

Carrying and Loading of the Spine
The risk that carrying poses for the spine has not yet been fully explored. Previous studies have either examined carrying’s effect on physiologic measures or have examined vary narrow sections of the spine using biomechanical models. Additionally, most studies have tested a limited selection of …

Hip and Spine in Cerebral Palsy
Abstract Background: Children with cerebral palsy (CP) have an increased risk of scoliosis, contractures including windswept hip deformity (WS), and hip dislocation. In 1994, a follow-up program and registry for children and adolescents with CP (CPUP) was initiated in Sweden to allow the early …

Computationally Efficient Finite Element Models of the Lumbar Spine for the Evaluation of Spine Mechanics and Device Performance
<p>Finite Element models of the lumbar spine are commonly used for the study of spine mechanics and device performance, but have limited usefulness in some applications such as clinical and design phase assessments due to long analysis times. In this study a computationally efficient L4-L5 FSU …

Development of laboratory spine with artificial muscles
… research is to develop an artificial laboratory spine that will have the same physical and biomechanical properties as the human spine. Validation of computer model is difficult hence an active artificial laboratory spine is being developed. A number of spinal elements have been produced and are …

Generalizable Methods for Modeling Lumbar Spine Kinematics
<p>A more complete understanding of lumbar spine kinematics could improve diagnoses and treatment of low back pathologies and may advance the development of biomechanical models. Kinematics describes motion of the five lumbar vertebrae without consideration for the forces that cause the motion. …

Screw fixation of implants to the spine
… are used to fix various implants to the human spine. Screw fixation can be difficult in osteoporotic bone because of its reduced strength. This research aimed to investigate screw fixation techniques in the spine. A questionnaire study, representing British and Irish spine surgeons, confirmed …

A distributed electromechanical spine for bio-inspired robots
… is limited due to the lack of a flexible spine. A spine provides an animal's agility, a wide range of motion, balance, and efficiency. It can be created using motors, which have been widely used for robotic joints. However, this conventional method introduces design complexity, low …

Investigation of spine loading to understand vertebral fractures
… little is known about the in vivo loading of the spine that may contribute to vertebral fracture. Prior efforts to understand the possible contribution of spine mechanics to vertebral fractures have been limited by the inability to accurately assess in vivo spinal loading, especially in the …

Investigating Resource Utilization in Elective Spine Patients with Affective Disorders: A Retrospective Analysis of a Cohort of 1199 Elective Spine Patients
BACKGROUND: In elective spine surgery patients, affective disorders (ADs) are associated with increased preoperative opioid use to control pain, longer length of hospital stays, and increased postoperative readmission rates. When assessing healthcare resource utilization, how ADs influence …

Assessing the Use of Ultrasound to Quantify Spine Kinematics
… in measuring multiplanar in-vivo lumbar spine motion in various positions of flexion and axial rotation using two separate ultrasound-based methods and was compared to surface-based optoelectronic motion capture. 14 instances of outlier range of motion were detected with the sagittal …

Post fatigue changes in the stability of cervical spine
… disorders (MSDs) of the neck or cervical spine are a common problem in the modern workforce. An annual prevalence of 30% to 50% for neck pain among the general adult population was reported by the Task Force of Bone and Joint Decade on Neck Pain. Physical work demands, such as sustained …

Explicit Finite Element Modeling of the Human Lumbar Spine
… of the functional spinal unit (FSU) and lumbar spine are essential in design-phase device development and in assessing the mechanics associated with normal spine function and degenerative disc disease (DDD), as well as the impact of fusion and total disc replacement (TDR). Although experimental …

Global Airway Management of the Unstable Cervical Spine Survey
… patients with unstable fractures of the cervical spine. Aiming to ascertain whether video laryngoscopy (VL) has replaced awake flexible intubation (AFI) as the preferred technique for airway management, we conducted a global survey to evaluate current clinical practice. Methods After ethics …

Tshidilo: a step towards understanding spine care in Botswana
This study sought to understand spine care in Botswana by focusing on the experiences of patients in a lower income neighbourhood community clinic in the capital, Gaborone, and the network of health care professionals in the city who manage patients with spinal related disorders. Spinal related …

Biomechanics of the canine thoracolumbar spine in lateral bending
… of the biomechanical properties of the spine through increases or decreases in the range of motion or stability of the spine. A decrease in range of motion between two adjacent vertebrae subsequent to arthrodesis or ankylosis appears, clinically, to be well tolerated without significant …

Perioperative Risk of and Monitoring for Hyperglycemia in Spine Surgery
… cohort of patients admitted following planned spine surgery between April 2010 and October 2013. Methods: Data were collected from electronic medical records for variables including age, gender, ethnicity, insurance status, diabetes status, HbA1c, ASA class, type and duration of surgery, and …
