Abstract:

Human cadaveric spines were used to determine sagittal horizontal stability of spondylolysis. Eleven FSU got from six fresh cadaveric human spines were tested for intact FSU and spondylolysis by using shear force. Spondylolysis was significantly less stable than the intact spine(P<0.01). Spondylolysis makes lumbar spine unstable, reduces its ability to withstand the shear force, and mades it prone to slipper.

Key words: spondylolysis, lumbar instability, biomechanics
