In current society, degenerative disc disease is a very common situation. It can cause nerve root compression, lumbar spinal stenosis, and lumbar instability. In order to relief patients’ symptom, decompression and spinal fusion surgery were common practices by surgeons. In recent years, the concept of interspinous process Coflex device of non-fusion surgery is emerging to improve the complication of decompression surgery. The Coflex-F device is a minimally invasive lumbar fusion device that provides significant segmental stability with all the advantages of an interspinous implant. It can alternative to traditions pedicle screw fixation as an adjunct to spinal fusion. This study was divided into three researches with purposes to investigate the biomechanical behavior between the Coflex and Coflex-F devices using finite element model of the L1-L5 lumbar spine. The first research ...
