The operation was performed under general anaesthesia with the patient in the prone position and wearing a halo-jacket. Three had internal fixation using a Luque rectangle and wiring. Their mean age was 48 years. <\/jats:p><jats:p> Before operation the mean cervical kyphosis was 23\u00b0; this was corrected to a mean of 31\u00b0 of lordosis, a mean correction of 54\u00b0. All the patients were able to see straight ahead. One patient with normal neurology soon after operation became quadraparetic after one week; two others had unilateral palsy of the C8 root, which improved. There was subluxation at the site of osteotomy in four patients, and two of them developed a pseudarthrosis which required an anterior fusion. <\/jats:p>","DOI":"10.1302\/0301-620x.79b2.0790197","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T11:52:30Z","timestamp":1519213950000},"page":"197-203","source":"Crossref","is-referenced-by-count":187,"title":["OSTEOTOMY OF THE CERVICAL SPINE IN ANKYLOSING SPONDYLITIS"],"prefix":"10.1302","volume":"79-B","author":[{"given":"M.
