Abstract: Degeneration of the intervertebral disc is related to progressive changes in the disc tissue composition and morphology, such as water loss, disc height loss, endplate calcification, osteophytosis. These changes may be present separately or, more frequently, in various combinations. This work is aimed to the biomechanical investigation of a wide range of clinical scenarios of disc degeneration, in which the most common degenerative changes are present in various combinations. A poroelastic non-linear finite el… Show more

“…Based on these potentially important limitations, we examined perioperative complications for both procedures in a large contemporary inpatient data file in the state of Florida. 16 The latter captures 100% of hospital discharges in the inpatient setting in a given year. Data collection at the participating institutions represents a mandatory process and is performed by trained professional coders.…”

“…The data are routinely audited for errors. 16 Diagnostic and procedural codes were based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). First, patients who underwent E-TURP (ICD-9-CM code 60.29) and L-TURP (ICD-9-CM code 60.21) were identified from 2006 to 2008.…”

“…Furthermore, accurate prediction of how the spine responds under complex loads has been proven using the lumbar spine modeled by poroelastic material [11,[18][19][20][21]. Changes in the geometrical and material parameters that occurred in different degenerated discs are investigated, and the results showed that the axial displacement, facet force, and total fluid loss are reduced with increasing degeneration [5,22]. Results of the analysis of four intervertebral discs with different degenerated grades showed that the IDP is highest in flexion, and that IDP increases with the severity of degeneration [13].…”

“…The phenomenon of the healthy disc swelling because of osmotic potential was simulated by a 0.25 MPa boundary pore pressure at the outer surface of the spine [3,5,19]. Boundary pore pressure was linearly reduced to 0.1 MPa from the non-degenerated intervertebral disc to the seriously degenerated one because of consideration to the loss of proteoglycans caused by disc degeneration [22].…”
