This technique uses a percutaneous dorsal approach to remove small portions of ligament and lamina, thereby restoring space and decompressing the spinal canal.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n Two-year data are reported for 45 patients treated with mild decompression at 11 US sites. Outcome measures included the Visual Analog Scale (VAS), Oswestry Disability Index, and Zurich Claudication Questionnaire. Safety was monitored throughout the procedural and follow-up period for all patients. Interim data are included for these patients at 1 week, 6 months, and 1-year follow-up.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Seventy-one percent of patients reported improvement in VAS at the end of the reporting period. At 2 years, patients demonstrated a statistically significant reduction of pain as measured by VAS, and improvement in physical function and mobility was significant as measured by Zurich Claudication Questionnaire and Oswestry Disability Index. Tukey honestly significant different test found significant improvement in all outcome measures from baseline to each follow-up interval. Further, major improvement occurred by 1-week follow-up and showed no difference between each subsequent follow-up, signifying considerable stability and durability of the initial result over time. No major device or intraprocedural adverse events were reported.<\/jats:p>\n <\/jats:sec>\n \n Discussion:<\/jats:title>\n In this report of 2-year follow-up on 45 patients treated with mild percutaneous lumbar decompression, patients experienced statistically significant pain relief and improved functionality.<\/jats:p>\n <\/jats:sec>","DOI":"10.1097\/ajp.0b013e31827fb803","type":"journal-article","created":{"date-parts":[[2013,2,27]],"date-time":"2013-02-27T12:48:54Z","timestamp":1361969334000},"page":"939-943","source":"Crossref","is-referenced-by-count":19,"title":["Long-term Results of Percutaneous Lumbar Decompression for LSS"],"prefix":"10.1097","volume":"29","author":[{"given":"Bohdan W.","family":"Chopko","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-3-20240226","doi-asserted-by":"crossref","first-page":"806","DOI":"10.1097\/00007632-198511000-00005","article-title":"The pathomorphology of spinal stenosis as seen on CT scans of the lumbar spine.","volume":"10","author":"Schonstrom","year":"1985","journal-title":"Spine"},{"key":"R3-3-20240226","doi-asserted-by":"crossref","first-page":"865","DOI":"10.1097\/00007632-200004010-00016","article-title":"Patient outcomes after minimally destabilizing lumbar stenosis decompression: the Port-Hole technique.","volume":"25","author":"Kleeman","year":"2000","journal-title":"Spine"},{"key":"R8-3-20240226","doi-asserted-by":"crossref","first-page":"230","DOI":"10.1302\/0301-620X.36B2.230","article-title":"A radicular syndrome from developmental narrowing of the lumbar vertebral canal.","volume":"36","author":"Verbiest","year":"1954","journal-title":"J Bone Joint Surg Br"},{"key":"R9-3-20240226","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1097\/00007632-198401000-00004","article-title":"Pathoanatomy and pathophysiology of nerve root compression.","volume":"9","author":"Rydevik","year":"1984","journal-title":"Spine"},{"key":"R10-3-20240226","doi-asserted-by":"crossref","first-page":"569","DOI":"10.1097\/00007632-198906000-00003","article-title":"Edema formation in spinal nerve roots induced by experimental, graded compression.
