Abstract
Objective To observe early clinical effects of microplate fixation in open-door cervical expansive laminoplasty ( ELP ) by comparing with modified anchor fixation. Methods A total of 135 cases with multi-segment cervical spondylotic myelopathy( MCSM ) underwent open-door ELP and were followed up in our hospital. 75 patients undergoing ELP by microplate fixation were classified as group A,while 60 patients undergoing ELP by modified anchor fixation as group B. Results Two groups were followed up for 3 months on average. There were no significant differences with regard to operation time and blood loss between two groups( P >0. 05 ). The improvement rate of Japanese Orthopaedic Association( JOA ) scores were 58. 3% ± 10. 0% in group A and 57. 1% ±9. 2% in group B three months post-operation,which showed no significant differences between two groups( P >0. 05 ). The incidence of axial symptoms ( 28/75 ) in group A was somewhat lower than that ( 25/60 ) in group B at three months after operation ( P >0. 05 ). There was no significant difference between preoperative( 19. 1° ±5. 6° ) and postoperative( 18. 5° ±5. 8° ) cervical curvature angle in group A,whereas the mean value of postoperative angle( 17. 3° ±5. 4° ) was significantly smaller than that of preoperative one( 19. 2° ±5. 3° ) in group B at three months follow-up( P < 0. 05 ). The angle of the opened laminae was 43. 2° ±4. 5° for group A and 39. 1° ±4. 7° for group B,which showed no significant differ-ence( P >0. 05 ). Improvement rate of the range of motion( ROM ) of group A ( 82. 36% ) was somewhat higher than that 74. 59% in group B at three months after operation ( P >0. 05 ). Conclusions Both surgical protocols are effective on preventing reclose of opened laminae, moreover ELP by microplate fixation can achieve the stability quickly after operation, which can help patients to do functional exercises early, and is superior on reducing the loss of cervical curvature.关键词
