Abstract
Introduction
Anterior cervical discectomy and fusion is common surgical procedure for treatement of cervical spondylotic radiculopathy and or myelopathy after failure of conservative management. Previous studies of multilevel cervical discectomies and fusions have shown decrease fusion rates with increase number of surgical levels. fusion rate and sagittal contour is better with anterior plating but complications like increase dysphagia rates, tracheoesophageal lesions, plate malposition and accelerated adjacent disc degeneration, even when low-profile plates are used. Further To avoid the adverse effect of autograft harvesting techniques Allograft can be used. Cages were used to add stability and prevent graft complications. Stand alone PEEK cages filled with Allograft were used in 3–4 levels anterior cervical discectomy and fusion.
Material and Methods
33 patients 18 males 15 females 28 with cervical spondylotic radiculopathy and 5 With cervical spondylotic myelopathy was treated with multiple levels anterior cervical discectomies and fusion using stand alone PEEK cages filled with Allograft. Total numbers of levels114, 18 patient operated for 3 levels ACDF and 15 patients operated for 4 levels. Clinical evaluation using visual analogue scale (VAS), neck disability index (NDI), and patient satisfaction were analyzed. Cervical lordosis, cervical fusion and complications were assessed.
Results
Improvement of the clinical outcome and the radiological parameters were detected
Conclusion
3–4 levels anterior standalone PEEK cages filled with allograft is very good option for treatment of degenerative cervical disc disease with low complication rate, good clinical and radiological outcomes.
