Background: Neurogenic intermittent claudication (NIC) is the principle symptom of degenerative lumbar spinal stenosis. Percutaneous interspinous course of decompression gadgets (IPDs) have been designed as a substitute remedy to conservative remedy and to open decompressive surgical procedure for sufferers affected by NIC. Preliminary short-term outcomes had been encouraging. We current the long-term outcomes of a bunch of sufferers that we adopted to offer perception on long-term outcomes and effectiveness of this system in comparison with different decompression strategies.
Strategies: Fifteen sufferers operated for NIC by implantation of percutaneous IPDs have been prospectively monitored for reoperations or issues. Comply with-up (FU) was interrupted if the affected person was reoperated. Outcomes had been thought of poor if the affected person needed to be reoperated at any stage of the FU or if the remedy did not alleviate the ache after 6 months. Outcomes had been thought of common if the affected person nonetheless suffered some ache however didn’t require reoperation.
Outcomes: The sufferers had been adopted as much as 7 years after the preliminary surgical procedure. The imply size of the FU was three.53 years and all sufferers could possibly be adopted. On the finish of the FU, the outcomes had been good in solely 20.zero% (three/15), common in 13.three% (2/15) and poor in 66.7% (10/15).
Conclusions: Regardless of preliminary passable outcomes, long-term FU is disappointing, with 80% poor or common outcomes. The long-term reoperation fee is excessive (66.6%), will increase over time and is greater than after implantation of IPDs for decompression augmentation. Though this system is easy and protected, its effectiveness appears short-lived. We suggest cautious use and informing sufferers in regards to the danger of comparatively early failure and recurrence.
