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). The axial endplate bulge has been measured in specimens of the human lumbar spine by stereoroentgen-photogrammetric methods. The results confirm the prediction that the axial endplate bulge is comparable in magnitude to the linear compression of the motion segment. 2005-03-22 · Axial load was applied using a Dynawell [R] (Dynawell, Int., Billdal, Sweden) L-spine loading apparatus.

Axial loading spine

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). A variety of structures in the low back can cause axial or mechanical lower back pain, such as a degenerated disc, facet joint problems, and damage to soft tissues – muscles, ligaments, and tendons - and it is often difficult to identify which anatomical structure (s) is the underlying cause of the patient’s pain. Instruct proper tackling technique: no axial loading (spearing, which occurs when the head and neck is flexed between 20-30°and serves as the point of contact). This is the most common cause of cervical spine injuries in sport. Have medical staff to cover exercise sessions and games.

This will result in flexion-type of injuries. In the lumbar spine due to the lordosis, the center of gravity is posteriorly. Results: Accumulated spinal axial biomechanical loading affects the histologic, molecular, and immunohistochemical changes of mice L 3- L 5 intervertebral discs.

Methods: Individual spinal joint compliance in the coronal plane was measured for a series of 15 idiopathic scoliosis patients using axially loaded magnetic resonance imaging. Each patient was first imaged in the supine position with no axial load, and then again following application of an axial compressive load. Summary of background data: Computed tomography and magnetic resonance imaging still are performed with the lumbar spine in a supine relaxed position, which results in unloading of the spine and enlargement of the canal. 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 In the majority of instances, injury at this level results from axial loading of the cervical spine.

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. Fractures of the ring of C1 are sustained during axial loading. An axial load applied to the top of the head with the cervical spine in neutral position spreads apart the ring of C1 between the sloped articular surfaces of the occiput and C2. This results in multiple, displaced fractures of C1 (Jefferson fracture).

Back pain?

The presence of fever with spine or radicular pain should lead the physician to look for an axial skeletal infection first. A pilot study evaluating the effect of spine position and loading on the changes of disc hydration in vivo was conducted with three volunteers without low back pain history. Spines were scanned in neutral, flexion and extension positions. MRI was repeated after 6 hours of normal activity and 4 hours of heavy activity with a weighted vest.

Material and methods: A Dynatup Model 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. Patients presenting with spine or radicular pain associated with fever and weight loss are at increased risk of having an infectious process (see Fig. 272-1). The presentation of neoplastic processes can be similar.
