Repeat radiographic imaging was normal, but static and dynamic views of the C-spine were normal with no evidence of instability. Sprain of the Subaxial Cervical Spine in Childhood Although Jamal BT et al, claimed that fall was the most frequent cause of C-spine injury with facial fractures an...
with OPLL below the C-2 position in a kyphotic cervical spine. Although typical MRI failed to demonstrate an abnormality of the upper cervical cord in a neutral or extension position, placing the patient in a protruded-...
The maxilla was fixed to the operating table to maintain axial alignment and prevent movement during surgery. A standard ventral median approach to the cervical spine was performed [39]. A median longitudinal incision of the skin and subcutis was made, moving the various planes up to the ...
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)...
Multi-segment spineSpinal kinematicsSpinal mobilityBackground The effects of inflammation and ankylosis on spinal kinematics of patients with axial spondyloarthritis (axSpA) are poorly understood. Furthermore, existence of (mal)adaptive movement profiles within axSpA, and differences between movement profiles...
