Background
The purpose of this study was to assess prospectively operative results and complications of treatment of cervical spinal canal stenosis (CCS) by anterior cervical discectomy and fusion (ACDF) using a newly introduced Alexandria Modular Cage-Plate Construct (AMCPC).
Methods
Fifteen patients (eight males, seven females) with symptomatic CCS were treated by ACDF, with a mean age of 51.2 years. Post-operative assessment depended upon clinical and radiological results.
Results
Total number of operated levels was 25 levels, with a mean 1.67 levels/patient. Mean operative time was 69.6 min/level and 116 min/patient. Average blood loss was 78 mL/level and 130 mL/patient. Mean hospital stay was 2.8 days. Post-operative dysphagia/dysphonia persisted in one patient for 1 year. One patient developed C5 radiculopathy with grade 2 deltoid weakness that recovered after 3 months. According to Odom’s criteria, results were excellent in 13 patients (86.67 %), good in 1 (6.67 %), and fair in 1 patient. In 13 patients (23 cage-plates, 92 %), the implant showed to be completely contained until the end of follow-up (24 months). One patient had a broken screw and one had screw backing-out, both did not necessitate revision. The achieved sagittal profile was maintained without sinking-in of any cage.
Conclusion
AMCPC can be used safely for a variety of disorders requiring instrumentation and fusion. It is advantageous to stand-alone cage and to rigid cage-plates when intraoperative flexibility is needed. It overcomes the disadvantages of stand-alone cage, sinking-in, cage dislodgement and post-operative rekyphosis. In addition, it obviates the need for wearing post-operative neck collar.
