RTI Surgical has announced a limited launch of its new Unison-C system. This anterior cervical fixation system is indicated for stand-alone interbody fusion for the treatment of single-level degenerative disc disease from C2 to T1, in skeletally mature patients.
The first human implantation of the device also took place in mid-February, as part of an anterior cervical discectomy and fusion (ACDF) procedure.
The Unison-C implant consists of an intervertebral body device made of PEEK-OPTIMA (Invibio) with an integrated locking mechanism and two screws. The Unison-C System is designed to be used with autograft and/or allograft.
This standalone device is contained and secured within the disc space, alleviating the need for supplemental fixation, such as an anterior plate and screws. In order to improve surgical efficiency, the system’s instrumentation features an all-in-one implant inserter and guide, which allows surgeons to complete all required steps from insertion to final locking.
“The instrumentation is designed with efficiency in mind. I appreciate the fact that I can place the implant, deploy the fixation and secure the locking mechanism all through a single instrument,” says Joseph Blythe, an orthopaedic surgeon at St Thomas Midtown Hospital, Nashville, USA. “I feel that the streamlined surgical technique combined with a stable zero profile construct gives my patients the greatest potential for a successful outcome.”
