ABSTRACT

Objective. This study evaluates the efficiency of interbody polyetheretherketone (PEEK) cage implantation in 15 consecutive cases treated for discogenic cervical disorders with radiculopathy or myelopathy at the Neurosurgery Service in Hospital Juárez de México. Methods. Between the years 2004-2007, 15 patients were treated with cervical interbody fusion using a PEEK cage. There were 9 male and 6 female patients and the mean age was 57 years (range, 34-75 years). PEEK cages were not packed with demineralised bone grafts. Additional plating was not used in any case. The median duration of follow-up was 6 months. Cervical x-rays were routinely used in the followup to assess the fusion, pseudoarthrosis, kyphosis, cage migration, subsidence or breakage. Results. In our study, the use of PEEK implants shows good clinical and radiological results, without complications and faster clinical recovery. Conclusions. Efficient interbody replacement is still an ongoing problem in cervical surgery. Different techniques and materials have been developed to overcome this problem. The use of a cervical PEEK cage seems to be a good alternative in that it does not require additional anterior plating and bone graft harvesting for achieving cervical interbody replacement.
