Abstract：Objective To investigate health-related quality of life ( HRQOL ) after personalized kyphosis correction in ankylosing spondylitis ( AS ).Methods Forty AS patients with fixed thoracolumbar kyphosis were treated with pedicle subtraction osteotomies ( PSO ) in our hospital from January 2007 to November 2011. All patients with no spinal cord neurological signs and good hip range of motion in both sides were divided into two groups under randomized method. Closing wedge osteotomy correction and pedical screw fixation of single segment or double segments from posterior approach were performed in both groups. Group A was treated with personalized PSO and group B was treated with traditional PSO. Pre- and post-operative pelvic incidence ( PI ), pelvic tilt ( PT ) were measured. The scoliosis research society-22 ( SRS-22 ) questionnaire and Oswestry disability index ( ODI ) were used to evaluate clinical results. Analyses of assessing scores and the relationship between PI and PT preoperatively and postoperatively were conducted.Results There were no signiifcant differences between group A and group B in pre-operative PI, PT, ODI and SRS-22 (P>0.01 ). All of the patients experienced improvement in appearance, psychology, pain, function and satisfaction, especially ODI. There were no signiifcant differences between A and B in post-operative ODI, SRS-psychology, pain, function and satisfaction (P>0.01 ) but SRS-appearance (P=0.0020 ), which were ( 4.6±0.3 ), ( 4.3±0.3 ) respectively.Conclusions Personalized kyphosis correction can improve the quality of life for AS patients after the operation. It also has better controllability on the correct angle of the chin-brow. Mastering of the personalized method can signiifcantly simplify discussions and controversies of the operation plan to achieve similar even better effects compared with traditional method.
