Hence, we have reported the use of posterior intra-articular C1\u20132 facet distraction, fixation, and cantilever technique versus foramen magnum decompression in treating type B basilar invagination as well as the results and surgical indications for this procedure.Methods: This was a single-center retrospective cohort study. Fifty-four patients who underwent intra-articular distraction, fixation, and cantilever reduction (experimental group) and foramen magnum decompression (control group) were enrolled in this study. Distance from odontoid tip to Chamberlain\u2019s line, clivus-canal angle, cervicomedullary angle, craniovertebral junction (CVJ) triangle area, width of subarachnoid space and syrinx were used for radiographic assessment. Japanese Orthopedic Association (JOA) scores and 12-item Short Form health survey (SF-12) scores were used for clinical assessment.Results: All patients in the experimental group had a better reduction of basilar invagination and better relief of pressure on nerves. JOA scores and SF-12 scores also had better improvements in the experimental group postoperation. SF-12 score improvement was associated with preoperative CVJ triangle area (Pearson index, 0.515; p = 0.004), cutoff value of 2.00 cm&lt;sup&gt;2&lt;\/sup&gt; indicating the surgical indication of our technique. No severe complications or infections occurred.Conclusion: Posterior intra-articular C1\u20132 facet distraction, fixation, and cantilever reduction technique is an effective treatment for type B basilar invagination. As various factors involved, other treatment strategies should also be investigated.<\/jats:p>","DOI":"10.14245\/ns.2244910.455","type":"journal-article","created":{"date-parts":[[2023,6,30]],"date-time":"2023-06-30T00:54:17Z","timestamp":1688086457000},"page":"498-506","update-policy":"https:\/\/doi.org\/10.14245\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Intra-articular Distraction Versus Decompression to Treat Basilar Invagination Without Atlantoaxial Dislocation: A Retrospective Cohort Study of 54 Patients"],"prefix":"10.14245","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8407-5637","authenticated-orcid":true,"given":"Boyan","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8971-666X","authenticated-orcid":true,"given":"Maoyang","family":"Qi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5980-1473","authenticated-orcid":true,"given":"Zong","family":"Xin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-8604-4955","authenticated-orcid":true,"given":"Yueqi","family":"Du","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9191-3328","authenticated-orcid":true,"given":"Can","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0827-4420","authenticated-orcid":true,"given":"Zhenlei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7244-9119","authenticated-orcid":true,"given":"Jian","family":"Guan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4830-1430","authenticated-orcid":true,"given":"Zuowei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0862-7345","authenticated-orcid":true,"given":"Fengzeng","family":"Jian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4751-3666","authenticated-orcid":true,"given":"Wanru","family":"Duan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0104-115X","authenticated-orcid":true,"given":"Zan","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5355","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1227\/01.neu.0000365770.10690.6f"},{"key":"ref2","first-page":"281","volume-title":"Treatment of basilar invagination by atlantoaxial joint distraction and direct lateral mass fixation.
