Abstract
Introduction
Anterior cervical discectomy and fusion (ACDF) is widely accepted as the standard intervention for symptomatic cervical disc disease. This involves the removal of the native disc and replacement with an implant to increase disc height and stabilise the vertebral segment. Two implants are used routinely to treat these cases surgically; these are Zero-Profile devices (Zero-P) and Stand- Alone cages (S-A). The present study aimed to evaluate the radiological and biomechanical outcomes of Zero-P and S-A implants for both single and multi-level cervical disc disease. The results of this study will aid surgical decision making, specifically choice of implant.
Methods
A total of 420 patients were reviewed retrospectively over a five-year period (April 2015 – December 2021) in a single institution. Following the exclusion criteria, 233 cases were included and followed up beyond the time for bone fusion to occur. The Zero-P group consisted of 117 cases, with 116 in the S-A group. Radiographic assessment was implemented at the pre-operative, day one post-operative, and follow-up stages. These included measurements of disc height, subsidence, segmental Cobb angle, and spondylolisthesis.
