Interspinous process device versus standard conventional surgical decompression for lumbar spinal stenosis: randomized controlled trial

STUDY QUESTION Is interspinous process device implantation more effective in the short term (eight weeks) than conventional surgical decompression for patients with intermittent neurogenic claudication due to lumbar spinal stenosis? SUMMARY ANSWER The use of interspinous implants did not result in a better outcome than conventional decompression, but the reoperation rate was significantly hig...

Adjacent segment degeneration in the lumbar spine.

BACKGROUND A primary concern after posterior lumbar spine arthrodesis is the potential for adjacent segment degeneration cephalad or caudad to the fusion segment. There is controversy regarding the subsequent degeneration of adjacent segments, and we are aware of no long-term studies that have analyzed both cephalad and caudad degeneration following posterior arthrodesis. A retrospective invest...

Interspinous Process Decompression: Expanding Treatment Options for Lumbar Spinal Stenosis

Interspinous process decompression is a minimally invasive implantation procedure employing a stand-alone interspinous spacer that functions as an extension blocker to prevent compression of neural elements without direct surgical removal of tissue adjacent to the nerves. The Superion® spacer is the only FDA approved stand-alone device available in the US. It is also the only spacer approved by...

Biomechanical comparison of an interspinous device and a rigid stabilization on lumbar adjacent segment range of motion.

PURPOSE OF THE STUDY Decompression surgery with or without fusion is the gold standard treatment of lumbar spinal stenosis, but adjacent segment degeneration has been reported as a long-term complication after fusion. This led to the development of dynamic implants like the interspinous devices. They are supposed to limit extension and expand the spinal canal at the symptomatic level, but with ...
