Abstract:
BACKGROUND: There are various kinds of design methods about preoperative osteotomy of ankylosing spondylitis with kyphosis, but each has their own errors and limitations. A convenient, precise and available method needs to bedeveloped.OBJECTIVE: To compare the clinical efficacy of two different preoperative osteotomy designs using paper-cut andphotoshop software for ankylosing spondylitis with kyphosis.METHODS: Thirty-nine patients suffering ankylosing spondylitis with kyphosis undergoing osteotomy in the Departmentof Spinal Surgery, Affiliated Hospital of Yan'an University between June 2009 and January 2015 were enrolled, andrandomly allotted to paper-cut (n=19) and photoshop (n=20) groups, followed by the preoperative osteotomy design,respectively. All patients were followed for 12-40 months to compare the postoperative osteotomy angle error andcorrection efficacy at the last follow-up between groups.RESULTS AND CONCLUSION: (1) The postoperative osteotomy angle error in the photoshop group was significantly smaller than that in the paper-cut group (P < 0.05). (2) At the last follow-up, the key parameters of sagittal spine and pelvis (sagittal vertical axis, Cobb angle and pelvic tilt) showed significant differences between groups (P < 0.05). (3) The Oswestry disability index and Scoliosis Research Society-22 questionnaire scores in the photoshop group weresignificantly superior to those in the paper-cut group at the last follow-up (P < 0.05), while the visual analog scale scoresdid not differ significantly between groups (P > 0.05). (4) To conclude, compared with the osteotomy design usingtraditional paper-cut splice, the photoshop software can achieve a smaller osteotomy angle error and better postoperative balance of spinal sagittal plane, thus providing precise osteotomy for surgeons to obtain proper correction.
