Results from a multicentre European prospective registry for the Baguara C prostethic cervical disc (Spineart) have shown good mobility at the treated and adjacent levels, disc height restoration and clear evidence of adjacent levels preservation.
The retrospective analysis of a large range of radiographic parameters, published in the Journal of Spine, was performed by an independent evaluator. Ninety-nine patients, treated for symptomatic degenerative disc diseases by one- or two-level arthroplasty—using a total of 123 BAGUERA C—prostheses were included.
Radiographic images at the treated and adjacent levels, as well at the overall cervical region, were analysed.
The results, 2 years after treatment by arthroplasty using Baguera C, also demonstrated no signs of subsidence of the prostheses. Measures at the adjacent levels showed no signs of degeneration or kyphosis. Occurrence of heterotopic ossifications was considered low compared to data published by independent evaluators for other disc prosthesis.
According to a company release, the author considered the results encouraging in terms of adjacent level disease protection.
So far, more than 15,000 Baguera C disc prosthesis have been implanted successfully worldwide. The first surgery was performed in France in January 2007.
