Abstract:
[Objective]To describe the clinical applycation of domelike decompression of the lumbar vertebral canal and evaluate the outcomes.To evaluate the effects on lumbar stability of domelike decompression through biomechanical canal study.[Method]Domelike decompress of the lumber vertebral canal were performed in 197 patients,with an average age of 52.7 and an average history of 6 years and 8 months,The surgicall outcomes were evaluated with modify Japanese Orthopedic Association Low Back Pain Score(M-JOA).Biomechanical study were performed on lumbar specimens from thirty fresh porcine model which were divided into three groups,Group A(n=10)was biomechanically tested after simulated laminectomy decompression,Group B(n=10)was biomechanically tested after simulated domelike decompression,Group C(n=10)was biomechanicaliy tested on intact,All were tested in flexion extension,torsion,and lateral bending and axial rotation moments as well as axial compressive loads.Load deflection curves were obtained each time,and stiffness values were calculated from the curves,Differences were checked for significance(P
