ABSTRACT

BACKGROUND:

With the disadvantages of lumbar fusion surgery complications and adjacent vertebral degeneration aggravating against the normal lumbar biomechanical characteristics, lumbar dynamic fixation technology in line with the normal lumbar biomechanics emerges as the times require. Lumbar interspinous distraction system as a representative of lumbar dynamic fixation technique has attracted extensive attentions of the field of spine surgery.

OBJECTIVE:

To review the current research progress of lumbar interspinous distraction system.

METHODS:

The first author retrieved in CNKI database and Wanfang database with the key words of "lumbar interspinous distraction device, interspinous distraction system, biomechanics, clinical application, lumbar interspinous distraction system complications", and searched PubMed database and SpringerLink database with the key words of "lumbar spine, interspinous process implant, interspinous devices, biomechanics, clinical application, postoperative complications". Recent studies were included after excluding the repeated studies. Finally, 55 studies were included, with 45 English studies and 10 Chinese studies. RESULTS AND

CONCLUSION:

(1) Lumbar distraction system core design concept was for expanding the interspinous space in the responsible segment and limiting their activities, which increases the spinal canal and foramen area, reduces intervertebral pressure, relieves nerve compression, can recover segmental stability to a certain degree, but does not significantly impact the motion range of adjacent segments. Simultaneously, it effectively avoids mechanical stimulation to the spinal cord and nerve root by opening the vertebral canal, replaces adjacent segments applied to the responsible section or combined application to fusion segments, and improves clinical symptoms and prevents the occurrence of adjacent vertebra disease. (2) Lumbar interspinous distraction device can effectively reduce stress load of intervertebral disc and small articular process, and maintain motion range of the corresponding segment. However, stress of the implant itself and upper and lower spinous process of the treated segments increases, warning that there is an increased risk of fracture of spinous process and fatigue fracture of the implant. (3) All kinds of lumbar interspinous distraction device have good clinical effect in short and medium follow-up. (4) The clinical curative effect of the distraction device can be comparable to spine fusion surgery. It is operated under local anesthesia, has small trauma, short operation time, quick recovery, short hospitalization time, less complications after surgery, retains lumbar motion range and prevents adjacent vertebral disease. Nevertheless, the device has some disadvantages, such as high medical cost, high revision rate, and inaccurate clinical effect.
