Five had intact facet joints, five had bilateral facetectomy of 50% or less, and four had bilateral 70% facetectomy. Three to 5 mm of root could be exposed in the specimens with 50% facetectomy, and 8 to 10 mm in those with 70% facetectomy. Anterior-posterior shear tests were run alternately in compression and distraction. Facetectomy was found to have no effect on compression and distraction stiffness. Failure in the 70% facetectomized specimens was due to fracture of the remaining joint at 159 lbs. In the specimens with 50% facetectomy, a fracture load could not be established since failure of the specimen mounting occurred at 208 lbs, as it did in two of the specimens without facetectomy that were tested to failure. The difference in bone fracture at 159 lbs and mounting failure at 208 lbs is significant at p &lt; 0.05. Bilateral resection of more than 50% of the facet joint significantly compromises the shear strength of a cervical spine motion segment.<\/jats:p>","DOI":"10.3171\/jns.1985.63.2.0278","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T18:39:08Z","timestamp":1241807948000},"page":"278-282","source":"Crossref","is-referenced-by-count":203,"title":["Cervical facetectomy and its effect on spine strength"],"prefix":"10.3171","volume":"63","author":[{"given":"Richard B.","family":"Raynor","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Pugh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilan","family":"Shapiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Orthop Trans (J Bone Joint Surg)","first-page":"46","article-title":"Stability of the cervical spine using a human cadaver model.","volume":"4","author":"Johnson","year":"1980"},{"key":"b2","series-title":"J Biomech","doi-asserted-by":"publisher","first-page":"327","DOI":"10.1016\/0021-9290(75)90085-8","article-title":"Cervical spine mechanics as a function of transection of components.","volume":"8","author":"Panjabi","year":"1975"},{"key":"b3","series-title":"J Biomech","doi-asserted-by":"publisher","first-page":"189","DOI":"10.1016\/0021-9290(78)90012-X","article-title":"Stability of the cervical spine under tension.","volume":"11","author":"Panjabi","year":"1978"},{"key":"b4","series-title":"J Bone Joint Surg (Am)","doi-asserted-by":"publisher","first-page":"37","DOI":"10.2106\/00004623-195941010-00006","article-title":"Total cervical-spine fusion for neck paralysis.","volume":"41","author":"Perry","year":"1959"},{"key":"b5","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"7","DOI":"10.1227\/00006123-198301000-00002","article-title":"Anterior or posterior approach to the cervical spine: an anatomical and radiographic evaluation and comparison.","volume":"12","author":"Raynor","year":"1983"},{"key":"b6","series-title":"Acta Orthop Scand Suppl","first-page":"1","article-title":"A rheologic model for cortical bone.
