Summary
Cervical spondylosis treatment using titanium cages showed high rates of subsidence, impacting spinal alignment. Despite this, functional outcomes improved significantly, though bone fusion was unsatisfactory.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical spondylosis causes neck and shoulder pain, sometimes leading to myelopathy and functional disability.
- Anterior cervical discectomy and fusion is a gold-standard treatment, with cervical mesh offering wider decompression but facing cage subsidence limitations.
Purpose of the Study:
- To evaluate surgical outcomes of anterior cervical decompression using titanium cages and anterior fixation.
- To determine if cage subsidence correlates with poor functional outcomes.
Main Methods:
- Retrospective observational study of 126 patients with at least 18-month follow-up.
- Review of clinical and radiological data from January 2008 to August 2011.
Main Results:
- 88.88% of patients experienced cage subsidence, primarily on the inferior platform.
- Significant functional improvement was observed (p=0.001) based on the Nurik scale.
- Postoperative complications occurred in 30.9% of patients, with loosening being the most frequent.
Conclusions:
- Cage subsidence led to loss of lordosis and sagittal imbalance, but without significant clinical impact.
- Bone fusion was unsatisfactory, and implant design hinders radiological evaluation.
- Improvements in implant design are needed to prevent subsidence and enhance bone fusion.
