Purpose: To evaluate the effect of compressive axial loading in imaging of the lumbar spine in patients with clinically suspected spinal stenosis. Material and
Edema in the vertebrae of the lower C-spine and upper T-spine indicating bone bruise as a result of axial loading. In this patient we can conclude that there was mild hyperflexion strain and we do not know if a special treatment is required, since these were isolated MR-findings without evidence of fracture or abnormal positioning. Finite Element Analysis of Axial Loading of the Cervical Spine. This is why, as clinicians, we often see Rugby players with injuries at the level of C4 in the cervical spine, and in some cases we can see catastrophic fracture dislocations of C4. Axial loading should not be performed in patients with severe neck or cervical spine injury. Evidence [edit | edit source] A systematic review performed by Fishbain et al, concluded that Waddell signs do not identify psychogenic pain nor does it differentiate organic from non-organic problems. In the majority of instances, injury at this level results from axial loading of the cervical spine. Lesions were distributed into specific categories: 1) acute intervertebral disc herniation (N = 4), 2) anterior subluxation of C3 on C4 (N = 4), 3) unilateral facet dislocation (N = 6), 4) bilateral facet dislocation (N = 7), and 5) fracture of vertebral body C4 (N = 4).
Axial loading: In axial loading patient stands and the examiner presses downwards vertically on the patient’s head, eliciting lumbar pain. Acetabular rotation: The examiner rotates the shoulder and the pelvis passively in the same plane while the patient is standing. It is a positive sign if pain is elicited in the first 30 degrees of rotation. AXIAL LOADING OF THE SPINE IN PATIENTS WITH SUSPECTED LUMBAR SPINAL STENOSIS ing CT and MR examinations, the patient is posi- tioned as comfortably as possible, e.g. with the hips and knees flexed. The effects of flexion and extension on spinal canal diameters and DCSA are well documented. However, the effects of axial loading, achieved by upright standing or by a compression device, are still unclear.
Abstract. Background: The aim of our study was to evaluate the incoming interrelations between chronic low back pain and biomechanical changes of the lumbar spine, using an MRI-compatible axial-loading device mimicking the standing position.
The occiput compresses the occipital condyles with force then transmitted to the sloped lateral masses of C1 causing radial displacement of the fracture fragments away from the spinal canal. Axial low back pain can vary widely.
Axial pain is characterized by pain that localizes to the cervical spine without motor or sensory dysfunction in the hands or lower extremities. Optimizing posture, ergonomics, and muscle strength can prevent the onset and help mitigate the symptoms of axial neck pain.
Under an axial loading similar to that created by the upright posture, the dural sac narrowed at the C5-6 interspace in asymptomatic individuals and at the C6-7 interspace in patients with cervical DDD. Axial loading injuries A burst fracture of the atlas is typically caused by an axial loading force (diving injury) to the cranium and is called a Jefferson fracture. The occiput compresses the occipital condyles with force then transmitted to the sloped lateral masses of C1 causing radial displacement of the fracture fragments away from the spinal canal. Axial low back pain can vary widely. It can be a sharp or dull pain, it can be felt constantly or intermittently, and the pain can range from mild to severe.
Specifically, the C3-C4 lesions appear to be unique with regard to the infrequency of bony fracture, difficulty in effecting and maintaining reduction, and a more favorable recovery following early, aggressive treatment.

MRI was repeated after 6 hours of normal activity and 4 hours of heavy activity with a weighted vest. Axial pain is characterized by pain that localizes to the cervical spine without motor or sensory dysfunction in the hands or lower extremities. Optimizing posture, ergonomics, and muscle strength can prevent the onset and help mitigate the symptoms of axial neck pain.

This device consists of a harness/jacket with straps connected to a footplate. By tightening the straps, an axial load can be applied to the patient's spine during
29 Mar 2007 Supine LBNP treadmill exercise provides axial loads to the lumbar spine and may prevent lumbar spine deconditioning associated with. The lateral, anterior and posterior passive bend- ing responses of the human cervical spine were inves- tigated using unembalmed cervical spinal elements ob -. Conclusion This study showed that spinal lumbar and thoracic stiffness increases when body position is changed from prone to standing.

A special non-magnetic device Methods: A device for axial loading of the lumbar spine in computed tomography and magnetic resonance imaging was used. Altogether, 172 patients were examined in psoas-relaxed position and axially compressed supine position of the lumbar spine: 50 patients with computed tomographic myelography and 122 patients with magnetic resonance imaging. Moderately severe axial loading with the cervical spine in neutral position causes vertebral body failure with central depression of the subjacent superior end plate, most often at C5. With massive axial loads, the intervertebral disk herniates through the end plate of the subjacent vertebral body and causes the body to explode from within, dispersing the fragments (burst fracture). Axial loading is top-down loading – meaning the weight during the lift is moving vertically instead of horizontally.

Some exercises are contraindicated in patients with degenerative disc disease. Weightlifting that increases axial load (weight in line with the spine) can make pain worse. These exercises include leg presses (when done seated with hand grips), deadlifts, military presses and lunges with the load on the shoulders.
Deformation of the vertebral end-plate under axial loading of the spine. Brinckmann P, Frobin W, Hierholzer E, Horst M. Spine, 01 Nov 1983, 8(8): 851-856 DOI: 10.1097/00007632-198311000-00007 PMID: 6670020 .
In the majority of instances, injury at this level results from axial loading of the cervical spine. Lesions were distributed into specific categories: 1) acute intervertebral disc hernia tion (N = 4), 2) anterior subluxation of C3 on C4 (N = 4), 3) unilateral facet dislocation ( N = 6), 4) bilateral facet dislocation ( N = 7), and 5) fracture of vertebral body C4 (N = 4).
In this patient we can conclude that there was mild hyperflexion strain and we do not know if a special treatment is required, since these were isolated MR-findings without evidence of fracture or abnormal positioning. In the majority of instances, injury at this level results from axial loading of the cervical spine.
The presence of fever with spine or radicular pain should lead the physician to look for an axial skeletal infection first.
