Abstract：To analyze the perspective of interspinous ligaments and ligamentum flavum and provide the stress relaxation mechanical parameters for artificial ligament materials research,ligament injury and ligament anastomosis surgery.The specimen were fixted in soft tissue, after clamping in electronic pressure universal testing machine, the machine was driven with 1%/s strain increasing speed of specimen in 36.5 ℃ experimental temperature field ,90 experimental data were collected after experiment,the stress relaxation data and curves were output by the computer automaticly at 7 200 s.The amount of stress relaxation was 1.06 MPa, the ligamentum flavum group was 1.62 MPa.The interspinous ligaments and ligamentum flavum have different stress relaxation mechanical properties.
