However, very late implant-bone interface failure is not well documented in the clinical literature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st2\">\n                    <jats:title>Case Description:<\/jats:title>\n                    <jats:p>A 54-year-old male without osteoporosis underwent stand-alone clamp-type metallic interspinous fixation at the L4\/5 level for axial low back pain with stable Grade I degenerative spondylolisthesis. Fourteen years later, he developed severe motion-provoked focal pain at the prior surgical site. Dynamic radiographs demonstrated marked bony erosion\/osteolysis at the instrumented level with implant malfunction. Implant removal resulted in substantial symptom relief.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st3\">\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This case highlights very late failure of stand-alone clamp-type metallic interspinous fixation device at the L4\/5 level. Studies revealed progressive peri-implant osteolysis\/erosion with loosening causing mechanical low back pain. The failure of this interspinous device underscores the need for long-term patient surveillance following the placement of a stand-alone interspinous process fixation device.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.25259\/sni_1461_2025","type":"journal-article","created":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T06:53:06Z","timestamp":1771570386000},"page":"101","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Lumbar stand-alone interspinous fixation without decompression or bone graft: A 14-year cautionary case of late mechanical failure"],"prefix":"10.25259","volume":"17","author":[{"given":"Masahiro","family":"Kawanishi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naokado","family":"Ikeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makoto","family":"Yamada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kunio","family":"Yokoyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Sugie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yutaka","family":"Ito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidekazu","family":"Tanaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2026,2,20]]},"reference":[{"key":"10.25259\/SNI_1461_2025\/ref-1","doi-asserted-by":"crossref","first-page":"2091","DOI":"10.3390\/jcm8122091","article-title":"Periprosthetic osteolysis: Mechanisms, prevention and treatment","volume":"8","author":"Goodman","year":"2019","journal-title":"J Clin Med"},{"key":"10.25259\/SNI_1461_2025\/ref-2","doi-asserted-by":"crossref","first-page":"881","DOI":"10.1007\/s00586-023-08119-z","article-title":"Is the interspinous process device safe and effective in elderly patients with lumbar degeneration?
