Abstract：Objective To analyze the early outcomes of anterior cervical discectomy and fusion ( ACDF ) using zero-proifle and self-locking cages in the treatment of 3-level cervical spondylosis. Methods From December 2011 to June 2012, 35 patients with 3-level cervical spondylosis underwent ACDF with zero-proifle and self-locking cages. There were 23 males and 12 females, whose mean age was 46.7 years old ( range:35-72 years ) and mean course was 9.7 months ( range:3-32 months ). Study parameters included the visual analogue scale ( VAS ) score, Japanese Orthopaedic Association ( JOA ) score, neck disability index ( NDI ) and lordosis angle of the cervical spine. Results The operation was successfully performed in all the cases. The mean operation time was ( 118±19 ) min and the mean blood loss was ( 95±43 ) ml. The follow-up period was 6 months. When compared with the preoperative scores, the VAS scores of neck and upper limb pain, JOA scores and NDI were obviously improved at 1 week, 6 weeks, 3 months and 6 months after the surgery. There were statistically signiifcant differences among them ( P<0.05 ). The lordosis angle of the cervical spine was ( 7.4±3.5 ) ° preoperatively, which was increased to ( 15.6±3.1 ) °, ( 15.2±2.5 ) °, ( 14.9±3.5 ) ° and ( 14.9±3.9 ) ° at 1 week, 6 weeks, 3 months and 6 months after the surgery, and statistically significant differences existed ( P<0.05 ). Conclusions The early outcomes of ACDF using zero-profile and self-locking cages for 3-level cervical spondylosis is satisfactory and reliable, and the cervical alignment can be restored. The surgery has the advantages of small incision, less bleeding, clear surgery ifeld, high safety and little trauma.
