All patients underwent uninstrumented CC with autologous iliac crest or fibular strut grafting. Preoperative clinical and imaging details were collected, and the type and incidence of complications were studied. Univariate and multivariate analyses were performed to establish risk factors for the development of perioperative complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Overall, 12.4% of patients suffered at least 1 complication following CC. The incidence of major complications was as follows: C-5 radiculopathy, 1.3%; recurrent laryngeal nerve injury, 0.4%; dysphagia, 0.8%; surgical-site infection, 3.4%; and dural tear, 4.3%. There was 1 postoperative death (0.2%). On multivariate analysis, patients in whom the corpectomy involved the C-4 vertebral body (alone or as part of multilevel CC) were significantly more likely to suffer complications (p = 0.004). OPLL and skip corpectomy were risk factors for dural tear (p = 0.015 and p = 0.001, respectively). No factors were found to be significantly associated with postoperative C-5 palsy, dysphagia, or acute graft extrusion on univariate or multivariate analysis. Patients who underwent multilevel CC were predisposed to surgical-site infections, with a slight trend toward statistical significance (p = 0.094). The occurrence of a complication after surgery significantly increased the mean duration of postoperative hospital stay from 5.0 \u00b1 2.3 days to 8.9 \u00b1 6 days (p &lt; 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Complications following CC for CSM or OPLL are infrequent, but they significantly prolong hospital stay. The most frequent complication following CC is dural tear, for which a diagnosis of OPLL and a skip corpectomy are significant risk factors.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2016.3.focus1638","type":"journal-article","created":{"date-parts":[[2016,6,1]],"date-time":"2016-06-01T03:53:12Z","timestamp":1464753192000},"page":"E10","source":"Crossref","is-referenced-by-count":13,"title":["Complications following central corpectomy in 468 consecutive patients with degenerative cervical spine disease"],"prefix":"10.3171","volume":"40","author":[{"given":"Sauradeep","family":"Sarkar","sequence":"first","affiliation":[{"name":"Department of Neurological Sciences, Christian Medical College, Vellore, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bijesh R.","family":"Nair","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Christian Medical College, Vellore, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vedantam","family":"Rajshekhar","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Christian Medical College, Vellore, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-focus1638","series-title":"J Neurosurg","first-page":"108","article-title":"Anterior decompression for ossification of the posterior longitudinal ligament of the cervical spine","volume":"55","author":"Abe","year":"1981"},{"key":"b2-focus1638","series-title":"J Bone Joint Surg Am","first-page":"716","article-title":"Comparison of anterior and posterior iliac crest bone grafts in terms of harvest-site morbidity and functional outcomes","volume":"84-A","author":"Ahlmann","year":"2002"},{"key":"b3-focus1638","series-title":"Evid Based Spine Care J","first-page":"11","article-title":"Factors affecting hospital length of stay following anterior cervical discectomy and fusion","volume":"2","author":"Arnold","year":"2011"},{"key":"b4-focus1638","series-title":"J Neurosurg Spine","first-page":"205","article-title":"Anterior decompression combined with corpectomies and discectomies in the management of multilevel cervical myelopathy: a hybrid decompression and fixation technique","volume":"3","author":"Ashkenazi","year":"2005"},{"issue":"4 Suppl 2","key":"b5-focus1638","series-title":"Neurosurgery","first-page":"295","article-title":"Cervical corpectomy: complications and outcomes","volume":"63","author":"Boakye","year":"2008"},{"key":"b6-focus1638","series-title":"Neurosurgery","first-page":"595","article-title":"Incidence and prognostic factors of C5 palsy: a clinical study of 1001 cases and review of the literature","volume":"74","author":"Bydon","year":"2014"},{"key":"b7-focus1638","series-title":"J Neurosurg Spine","first-page":"37","article-title":"Patient comorbidity score predicting the incidence of perioperative complications: assessing the impact of comorbidities on complications in spine surgery","volume":"16","author":"Campbell","year":"2012"},{"issue":"3","key":"b8-focus1638","series-title":"Neurosurg Focus","first-page":"E12","article-title":"Approach-related complications after decompression for cervical ossification of the posterior longitudinal ligament","volume":"30","author":"Cardoso","year":"2011"},{"key":"b9-focus1638","series-title":"J Clin Neurosci","first-page":"233","article-title":"Anterior cervical corpectomy for cervical spondylotic myelopathy: experience and surgical results in a series of 70 consecutive patients","volume":"13","author":"Chibbaro","year":"2006"},{"key":"b10-focus1638","series-title":"J Neurosurg Spine","first-page":"33","article-title":"\u201cSkip\u201d corpectomy in the treatment of multilevel cervical spondylotic myelopathy and ossified posterior longitudinal ligament","volume":"12","author":"Dalbayrak","year":"2010"},{"key":"b11-focus1638","series-title":"Spine (Phila Pa 1976)","first-page":"1168","article-title":"Corpectomy versus laminoplasty for multilevel cervical myelopathy: an independent matched-cohort analysis","volume":"27","author":"Edwards","year":"2002"},{"key":"b12-focus1638","series-title":"J Bone Joint Surg Am","first-page":"1132","article-title":"Treatment of dural tears associated with spinal surgery","volume":"63","author":"Eismont","year":"1981"},{"issue":"1 Suppl","key":"b13-focus1638","series-title":"J Neurosurg","first-page":"35","article-title":"Cervical corpectomy: report of 185 cases and review of the literature","volume":"90","author":"Eleraky","year":"1999"},{"key":"b14-focus1638","series-title":"J Bone Joint Surg Am","first-page":"941","article-title":"Anterior cervical decompression and arthrodesis for the treatment of cervical spondylotic myelopathy.
