ResumoThe purpose of the present investigation was to determine the influence of nucleotomy for the biomechanical properties of the lumbar motion segment.From 11 human cadavers the lumbar-vertebral segment L3/4 was taken. The segment was tested by an 3D testing device. Measurements were taken under physiological loads up to 7 Nm. Load application was performed in flexion/extension, lateral bending and rotation direction. For each step translation and rotation were measured in three axis of space. Next measurement was performed after a nucleotomy simulated by rectangular excision of the anulus and total nucleotomy on an average of 6 g tissue.There was a significant relation (p < 0.05) between removed disc material and flexibility of the lumbar motion segment.The nucleotomy plays a crucial role in the segmental mobility.
