Abstract:
The implantation of interspinous process device is a minimal invasive surgical procedure for degenerative lumbar spinal diseases. At present, a variety of interspinous process devices designed can be subdivided into three categories based on different application principles: interspinous distraction device, interspinous fixation device and interspinous fusion device. The interspinous distraction devices distract interspinous interspace, enlarge spinal canal area and alleviate neurological symptom, which are mainly applied for lumbar spinal stenosis with intermittent neurogenic claudication. Interspinous fixation device has been used as an alternative technique to the pedicle screw fixation in lumbar interbody fusion due to gripping and fixating to spinous process. Interspinous fusion device utilizes rigid fixation to support fusion, which can be used as not only simple distraction device but also additional instrumentation for direct decompression and interbody fusion. All types of interspinous process devices are different in biomechanical characteristics due to its application concept. In this review, the author mainly focus on biomechanical research progress of interspinous process device in lumbar degenerative disease.
