Grahic Jump Location
Finite element model prediction of the motion segment’s mechanical behavior in an intact motion segment, in a motion segment with square annular incision and in a segment with annular injury combined with nucleotomy under all loads compared favorably with experimental results of Panjabi et al. 5
Grahic Jump Location
Finite element mesh of the annulus with the four incisions included in the current study are shown here. Even though the circular incision is circular in shape, the graphical package could only reproduce it with straight edges. One of the slits in the cross incision was filled with finite elements to model the slit incision.
Grahic Jump Location
Cross and slit incisions produced similar increase in motions under shear loads. Circular incision produced largest increase in motion under axial moment loading modes.
Grahic Jump Location
Disc flexibility increased by a large amount when in addition to the annular incision, nucleus was removed. Cross and slit incisions produced largest increase in motion under shear forces. Cross incision produced largest increase in motion in all moment loads except axial moment. Circular incision produced the largest increase in motion under axial moment.
Grahic Jump Location
The largest increase in facet load occurred in a motion segment with the circular incision. Increase in facet load was observed under anteriorly directed shear force, extension moment, and left axial moment loads.
Grahic Jump Location
The increase in facet load due to combined annulotomy and discectomy was much larger as compared to increase in facet load due to annular incision alone. The largest increase in facet load was produced by cross incision while the smallest increase in facet load was produced by the circular incision.
Grahic Jump Location
Coupled lateral translation and lateral rotational motions were large when nucleus was removed in addition to annulotomy. Lateral bending coupled motion was more pronounced with cross and slit incisions under extension and right axial moment loads. Axial rotation coupled motion was also found to increase predominantly under cross and slit incisions under right lateral bending moment load.
