to be the injury threshold (1990). He also reported that the threshold of inversion and eversion was 60 deg. (1993). As for tibia1 injury involving the ankle joint, a number of axial loading tests has been done. Yoganandan (1996) summarized tibia1 axial loading 2006-6-20 2008-9-30 2018-6-11 It’s the most common location for axial loading injuries.

One such force is axial load. This ScienceStruck post brings to you the definition of axial load, and also the formula for axial load calculation for better understanding. Axial loading is defined as applying a force on a structure directly along an axis of the structure. As an example, we start with a one-dimensional (1D) truss member formed by points P 1 and P 2, with an initial length of L (Fig. 1.2) and a deformed length of L′, after axial loading is applied. Download Citation | Axial loading with hyperflexion injury to the atlas resulting in crushed lateral masses | A 40-year-old man was involved in an ATV accident, in which he landed on the top of Computed tomography (CT) demonstrated vertical fractures of the anterior aspects of both lateral masses of the atlas, extending to the junction of the lateral mass with the anterior arch bilaterally. There was no lateral offset of the lateral masses.

In football and other contact sports, the cervical spine can regularly be exposed to hazardous forces from an impact. An axial load is a force administered along the lines of an axis. This is typically used to describe an injury in which there is compression of the spine from the head, such as when a person dives 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.

This resource describes the classic axial load injuries of the upper extremity. Nearly all of these injury sources imply axial loading as the mechanism of injury. METHODS TEST APPARATUS - Because axial loading has been implicated as the cause of common and severe foot and ankle injuries seen in real world car crashes, the Univer-sity of Virginia undertook a series of lower extremity impact tests designed to determine the 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). The Role of Axial Loading in Malleolar Fractures 2000-01-0155 Though rotation is thought to be the most common mechanism of foot and ankle injury in both automobile crashes and in everyday life, axial impact loading is considered responsible for most severe lower extremity injuries.

This will result in flexion-type of injuries. In the lumbar spine due to the lordosis, the center of gravity is posteriorly. Flexion type of injuries will straigthen the lumbar spine and result in axial loading.

This is typically used to describe an injury in which there is compression of the spine from the head, such as when a person dives dorsiflexion and found 45 deg. to be the injury threshold (1990). He also reported that the threshold of inversion and eversion was 60 deg. (1993). As for tibia1 injury involving the ankle joint, a number of axial loading tests has been done.
