Prospective 5-year follow-up of L5–S1 versus L4–5 midline decompression and interspinous-interlaminar fixation as a stand-alone treatment for spinal stenosis compared with laminectomies

Spinal stenosis patients treated with midline decompression and InSpan IFD, used as a stand-alone treatment for interspinous-interlaminar fixation, at L4–5 and L5–S1, showed improved outcome scores and low complication and revision rates at five years and were comparable to historical open laminectomy data.

L4-5 interspinous fixation - ap and late

Kingsley R. Chin^, Fabio J. R. Pencle, Amala Benny, Jason A. Seale

Long term results demonstrated improved outcomes in patients who underwent Interspinous distraction decompression in an ambulatory surgery center using the INSPAN IPD at L4−L5 for Degenerative Spinal Stenosis. There was one revision converted to hemilaminectomy. There were no complications or blood transfusions

InSpan works both as a distractor and internal decompressor of the spinal canal. It is simple to use and safe. Statistically significant improvement was reported at a median follow-up of 19 months

Biomechanical Study of InSpan Dual-Locking Set Screw Symmetrical Design versus Aspen Single-Locking Asymmetric Control

The dual-locking symmetrical InSpan IFD demonstrated superior fixation strength in both static disassembly and pullout bench tests compared to the Aspen IFD
