The Study Of Posterior Ligamentous Complexin Thoracolumbar Spine Injuries

ObjectiveTo definite the injuries types of PLC in thoracolumbar spine injuries and stability of the spine .MethodsNucleus pulposus surgically removed from SD mouse of 30 days was used in primary monolayer culture. Then the cultured cells were cultured in different oxygen concentration to induce HIF-1α's expression in different degree. Western-blot was used to detect HIF-1α's expression. Flew cytometry was used to detect cell apoptosis degree. Correlation analyze was used to assessed correlation of the HIF-1α's expression and cell apoptosis in nucleus pulposus in date statistics of the results.ResultsMagnetic resonance (MR) imaging examinations of 22 patients with thoracolumbar fractures were retrospectively evaluated to determine spinal ligament integrity. Radiographic and computed tomographic (CT) examinations were evaluated for interpediculate widening, midsagittal canal narrowing, posterior element fractures, and kyphosis; a radiographic assessment of posterior ligamentous integrity was made. These findings were then correlated with the status of the spinal ligaments. then contrast with the finding of operation .ConclusionThis classification will assists in clinical decision-making in terms of the need for operative versus nonoperative care and surgical treatment approach in unstable injury patterns.
