In retrospect there were some companies that attempted to get into this market segment. The companies that failed were Scient'x and Interpore Cross. If my memory serves me, Interpore's product was called the Vanguard. Today we have multiple companies that offer so-called zero profile cervical products. These include; Mosaic by Spinal Elements, which set the precedent for cervical devices and is still considered to be a good product. Bricon, a German company has a product called Cervical-C or Shark Cage, LDR has a product called ROI-C with its VerteBRIDGE plating technology. TSB must ask is there any biomechanical data on the efficacy of those blades that are used to stabilize this device? Centinel has the STALIF-C which has been struggling because of the V Brothers inability to transition anything smoothly. Synthes has the Zero-P, and Globus has a product of their own. In addition, to these devices there are a few smaller ventures that are playing in this space.
The most common complications associated with the anterior approach to the c-spine are sore throat and dysphagia. Yet, chronic dysphagia or hoarseness is an uncommon complication associated with injury to one of the recurrent laryngeal nerves. This type of injury may cause problems with swallowing and potential aspiration. But the question must be asked, have these post-op complications been a by product of surgical approach and soft-tissue management, or has the implant really been the culprit? TSB wants to know what our readers think?
