Abstract：Objective To compare the outcomes of modiifed open door laminoplasty with traditional operation for the treatment of cervical spondylosis.Methods From May 2012 to October 2014, 69 cases with cervical spondylosis combined with cervical instability, undergoing posterior laminoplasty and lateral mass screw ifxation, were reviewed retrospectively. Thirty-eight cases undergoing modiifed open door laminoplasty were classiifed into the modiifed group, and 31 cases undergoing traditional open door laminoplasty were classiifed into the traditional group. The modiifed group included 25 males and 13 females with the mean age of 52.6 years ( range: 42 - 67 years ). The traditional group included 18 males and 13 females with the mean age of 55.4 years ( range: 35 - 69 years ). Operation time, blood loss, complications, pre- and post-operative Japanese Orthopedic Association ( JOA ) score, neck Visual Analogue Scale ( VAS ) score, and the open angle 1 week postoperatively were used for the comparison between 2 groups. Results There were no signiifcant differences in operation time and blood loss between the 2 groups (P>0.05 ). Preoperative JOA and VAS scores were similar between the 2 groups (P>0.05 ). No signiifcant differences were demonstrated in postoperative JOA score, improvement rate of JOA score, and postoperative VAS score between the 2 groups (P>0.05 ). Open angles 1 week postoperatively was similar between the 2 groups (P>0.05 ). Open angle at last follow-up in the modiifed group was maintained better than that in the traditional group [ ( 43.27 ± 8.82 ) °vs. ( 37.42 ± 7.42 ) °,P < 0.01 ]. Seven cases ( 22.6% ) in the traditional group and 5 cases ( 13.2% ) in the modiifed group had axial symptoms after the surgery. Four cases ( 12.9% ) in the traditional group and 3 cases ( 7.9% ) in the modiifed group had C5 nerve root palsy after the surgery.Conclusions Modiifed open door laminoplasty can achieve similar clinical outcomes as the traditional operation, maintaining better open angle and reducing fracture dislocation than the traditional operation.
