M3 - Article. 2018 Jan 19;89(1-S):138-150. doi: 10.23750/abm.v89i1-S.7017. A meniscal tear can be caused by trauma or degenerative changes in the knee joint.Traumatic meniscal tears are usually associated with physical activity and typically result from rotation coupled with axial loading of the knee joint.The affected meniscus may be medial or lateral, with the medial frequently torn because of its relative immobility. J Biomech Eng. One of the most common injuries observed by orthopedic surgeons is the distal radius fracture (Lidstrom, 1959).The typical injury mechanism is a fall on the outstretched hand, thereby, producing an axial compressive force across the wrist on the distal forearm (Fisk, 1970, Hill, 1970, Linscheid et al., 1972, Short et al., 1987; Werner et al., 1992). These injuries often occur as a result of multiple forces applied to the knee: varus, valgus, hyperextension, hyperflexion, internal rotation, external rotation, anterior or … In the majority of instances, injury at this level results from axial loading of the cervical spine. View or download all the content the society has access to. NIH The patterns of injury in the upper and lower region are nicely illustrated in this image from the Radiology Assistant One of the most important rule change implementations was performed in 1976 when spear tackling was made illegal (Figure 1).

A study of robotic loading of cadaver knees suggested that axial loads create greater in situ forces in the ACL which implied that excessive axial loads may contribute to ACL injury.

Axial loading is useful in distinguishing soft tissue injury from a fracture. | Axial loading occurs when a force or pressure is applied parallel and on the centroid axis of an object. Diffuse axonal injury (DAI) is a form of traumatic brain injury. Chirvi S, Pintar F, Yoganandan N, Banerjee A, Schlick M, Curry W, Voo L. Bailey AM, McMurry TL, Poplin GS, Salzar RS, Crandall JR. Traffic Inj Prev. May represent a reduced knee fracture-dislocation and subsequent ligament injuries are common. Diagnosis of Axial Back Pain. In two cases of unilat eral facet dislocation reduced within 3 hours of injury and subsequently fused anteriorly, significant neuro logic recovery occurred. 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). ( By continuing to browse This is done to … Continue reading "Axial Loading" Author information: (1)Department of Radiology, University of Iowa Hospitals and Clinics, 200 Hawkins Drive, Iowa, IA 52242, USA. The centre of gravity is posterior to the spine. There was a significant increase in the tibia1 axial load in comparison with the impact load because of preloading by muscular tension. The email address and/or password entered does not match our records, please check and try again. With the lordosis, when there is a flexion injury, the lumbar spine actually straightens up and this causes burst fractures. DAI is one of the most common and devastating types of traumatic brain injury and is a major cause of unconsciousness and persistent vegetative state after severe head trauma. In the majority of instances, injury at this level results from axial loading of the cervical spine. lower legs. threshold of 6. Grigoriadis G, Carpanen D, Webster CE, Ramasamy A, Newell N, Masouros SD. Most commonly associated with neurovascular injury. b. Flexion, Extension, Rotation. JAMA 254: Torg JS, Vegso JJ, Torg E. Cervical quadnplegia resulting from axial loading injunes: Cinematographic, radiographic, kinetic and pathologic analysis. A buried pipeline may experience axial loads due to ground movement induced by slope instability. In football and other contact sports, the cervical spine can regularly be exposed to hazardous forces from an impact.
