There was a significant increase in the tibia1 axial load in comparison with the impact load because of preloading by muscular tension. When the neck is flexed slightly forward, the cervical spine becomes straight. Axial loading is useful in distinguishing soft tissue injury from a fracture. Refer to the image below to see what axial loading is. T1 - Classic Axial Load Injuries to the Upper Extremity. With the lordosis, when there is a flexion injury, the lumbar spine actually straightens up and this causes burst fractures. An analysis of three hundred hospitalized patients and review of the literature. Axial loading with hyperflexion injury to the atlas resulting in crushed lateral masses. the ligaments, cervical discs, bony structures, and the facet joints, which can cause adverse stress and injury. The other four patients, two who underwent an open reduction and laminectomy and two treated closed with skeletal traction, remained quadriplegic. In two cases of unilat eral facet dislocation reduced within 3 hours of injury and subsequently fused anteriorly, significant neuro logic recovery occurred. (Li et al., 1998) Further it has been demonstrated that high axial loads are capable of rupturing the ACL. Simply select your manager software from the list below and click on download. Scaphoid Fractures. Axial loading may be applied to the leg externally, by the toepan and/or pedals, as well as internally, by active muscle tension applied through the Achilles tendon during pre-impact bracing. The exact diagnosis as to which structure is causing the low back pain rarely has significance to treatment. In the majority of instances, injury at this level results from axial loading of the cervical spine.

Cervical quadnplegia resulting from axial loading injunes: Cinematographic, radiographic, kinetic and pathologic analysis. Abstract. Axial pain represents the most common type of low back pain, and it is usually non-specific – meaning that the anatomical structure responsible for the pain need not be identified because symptoms are usually self-limited and resolve with time. Axial loading of the foot/ankle complex is an important injury mechanism in vehicular trauma that is responsible for severe injuries such as calcaneal and tibial pilon fractures. [Gopinathan, 2018] Many involve C1 and C2. American Orthopaedic Society for Sports Medicine, Axial loading injuries to the middle cervical spine segment, https://doi.org/10.1177/036354659101900103.
