Cervial Disc Arthroplasty

Cervical Disc Arthroplasty (CDA) seems to be an alternative to Anterior Cervical Decompression and Fusion (ACDF). During the past two decades the effectiveness of CDA in treating cervical degenerative disc diseases has been analysed. CDA is a procedure that enables restoring of motion to the spine by replacing the degenerated and worn disc and was developed to minimise the risk of Adjacent Segment Disease (ASD).

The ROTAIO® Cervical Disc Prosthesis represents an new unconstrained implant with a variable centre of rotation, which should enable physiological facet-guided movement.

In the 24-months follow-up, the ROTAIO Cervical Disc Prosthesis provided excellent clinical and radiographical results and seems to be safe and effective for the treatment of symptomatic single-level degenerative disc disease. The patients had significantly improved NDI and VAS scores, showed a lower rate of NSAID-use and an excellent overall success at the last follow-up. Therefore, according to recent studies of other cervical disc prosthesis the results confirm and support the role of total disc replacement as an alternative to ACDF, studies focusing on clinical long-term outcome and especially on preserving ASD are warranted.

ATHLET – The real winner

Anterior cervical corpectomy and fusion (ACCF) has become standard procedure for patients with spondylotic myelopathy due to multisegmental stenosis of the cervical canal. In addition to the fusion technique using autogenous bone grafts and titanium implants, synthetic polyetheretherketone (PEEK) cages have been used increasingly during the last years. However, limited evidence on the clinical and radiological results of PEEK cages for ACCF exists in the literature. The latest studies have demonstrated that PEEK cages lead to equal clinical and radiological results and are a safe and effective alternative to titanium cages or autogenous bone graft for ACCF [1].

Also the shorter duration of surgery and term of postoperative stay support the thesis, that PEEK cage is superior to iliac crest bone fusion.

Synthetic vertebral body replacement requires top performance. Our ATHLET (athlitis = Greek for “the contestant”) meets this challenge.

Its unique concept combines all required characteristics in one product making it a real winner.
