Failure of he treatment can occur, generally related to bone remodelling\/fracture of spinous processes. PMMA augmentation of the posterior arch (spinoplasty, SP) has recently been proposed in case of neoplastic involvement. This study evaluated the efficacy of SP as a prophylactic treatment before introducing an interspinous spacer (IS). Moreover, we consider the possibility to treat patients who previously underwent IS implants with subsequent failure of the device, by introducing a second spacer at the same level, performing accessory SP. From January 2009 to September 2011, 174 patients with LSCS underwent CT-guided percutaneous IS implant in our department. From January 2011, all patients with osteoporosis underwent prophylactic SP before introducing the spacer. Moreover, in patients with re-stenosis related to bone remodelling and\/or fracture, after strengthening the spinous processes with PMMA introduction, a second similar device was introduced to re-open the stenotic spinal canal. In patients with prophylactic treatment before spacer introduction, no restenosis occurred at three to 12 month follow-up. Patients who underwent second spacer implant at the same level after posterior arch augmentation again obtained a resolution of symptoms, and no further bone remodelling had occurred at follow-up controls. In conclusion, prophylactic SP prevents single spacer failure for bone remodelling\/fracture, and allows failure repair by introducing a second spacer at the same level.<\/jats:p>","DOI":"10.15274\/inr-2014-10052","type":"journal-article","created":{"date-parts":[[2014,4,28]],"date-time":"2014-04-28T11:26:04Z","timestamp":1398684364000},"page":"626-631","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Posterior Arch Augmentation (Spinoplasty) before and after Single and Double Interspinous Spacer Introduction at the Same Level: Preventing and Treating the Failure?"],"prefix":"10.1177","volume":"20","author":[{"given":"Luigi","family":"Manfr\u00e9","sequence":"first","affiliation":[{"name":"Department of Minimal Invasive Spine Therapy, Cannizzaro Hospital; Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,1,1]]},"reference":[{"issue":"8","key":"bibr1-INR-2014-10052","first-page":"773","volume":"18","author":"Ohashi T","year":"1990","journal-title":"No Shinkei Geka"},{"key":"bibr2-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1097\/01.BRS.0000084877.88192.8E"},{"key":"bibr3-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-011-2129-3"},{"key":"bibr4-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1007\/s00064-010-9042-5"},{"issue":"6","key":"bibr5-INR-2014-10052","first-page":"311","volume":"91","author":"Hrab\u00e1lek L","year":"2012","journal-title":"Rozhl Chir"},{"key":"bibr6-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-011-1753-2"},{"key":"bibr7-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.3171\/2009.9.SPINE09144"},{"key":"bibr8-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A2792"},{"issue":"2","key":"bibr9-INR-2014-10052","first-page":"127","volume":"77","author":"Alp\u00edzar-Aguirre A","year":"2009","journal-title":"Cir Cir."},{"key":"bibr10-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1177\/159101991301900217"},{"key":"bibr11-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1177\/159101991301900216"},{"key":"bibr12-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-008-1328-9"},{"key":"bibr13-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200301010-00008"},{"key":"bibr14-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1097\/BSD.0b013e318031af6f"},{"key":"bibr15-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1007\/978-88-470-2790-9_11"},{"key":"bibr16-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2013.07.481"},{"key":"bibr17-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2013.07.458"},{"key":"bibr18-INR-2014-10052","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2013.07.436"}],"container-title":["Interventional Neuroradiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.15274\/INR-2014-10052","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.15274\/INR-2014-10052","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:56:10Z","timestamp":1777460170000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.15274\/INR-2014-10052"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,1,1]]},"references-count":18,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2014,9]]}},"alternative-id":["10.15274\/INR-2014-10052"],"URL":"https:\/\/doi.org\/10.15274\/inr-2014-10052","relation":{},"ISSN":["1591-0199","2385-2011"],"issn-type":[{"value":"1591-0199","type":"print"},{"value":"2385-2011","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,1,1]]}}}
