Description
Objectives: Interspinous process decompression (IPD) is a procedure that restricts lumbar spine extension through implantation of a spacer between adjacent spinous processes to reduce neurogenic claudication symptoms associated with lumbar spinal stenosis (LSS). Our study aims to determine whether a minimally invasive IPD provides relief to United States Military Veterans who have undergone the procedure over the past year. To achieve this, a health survey and a secondary questionnaire will compare pre-operative and post-operative results. Methods: Patients were administered an SF-12v2 survey pre-operatively and at several intervals up to 1-year post-operatively to assess their quality of life over time; there is a score for Mental Component Summary (MCS) and Physical Component Summary (PCS). The patients were then administered a customized secondary questionnaire to specifically monitor their improvement in pain on a scale of 1-10 and their improvement in the number of blocks walked post-operatively. The patients were also questioned on whether they received any postoperative injections, lumbar surgeries, and IPD explants. Opioids taken chronically were measured before and after the procedure; our conversion of hydrocodone to morphine was 1:1, and oxycodone to morphine was 1.5:1. Additionally, the patients were asked whether they would recommend Vertiflex, IPD, to a fellow veteran based on the improvement in their low back and leg pain. 20 patients are currently participating in the study, and 16 patients have been assessed at the 1-year time mark. Results: Of the 16 patients administered the SF-12v2, patients saw an average increase of 6.56 in their MCS score (p=0.054, p>0.05), while the change recorded in the PCS score was insignificant (p>0.05) Regarding the secondary survey, patients had an average decrease of - 1.69 in their pain score on the standardized 10-point pain scale (p=0.078, p>0.05). Additionally, patients saw an average increase of 2.04 city blocks walked post-procedure when measured using the average size of a city block according to the City of New Orleans Department of Public works (p=0.087, p>0.05). Relief in pain and increase in the number of blocks walked was insignificant thus far in the study. Patients taking opiates before the procedure had an average decrease of -23.09 morphine milliequivalents post-op (p=0.024, p
