Accelus has announced both the launch and first procedures performed utilising its TiHawk7 expandable interbody cage—the latest addition to its FlareHawk interbody fusion system portfolio of spinal fusion cages—which features a new ultra-low profile with titanium at the bony interface.
Chris Walsh, CEO and co-founder of Accelus, said: “TiHawk7 encompasses all of the implant advantages needed to make minimally invasive (MIS) spine procedures successful: an ultra-low insertion profile with multidirectional interbody expansion combined with the benefits of an innovative titanium and polyetheretherketone (PEEK) bonding process.
“Our titanium is deposited in a thin, uniform layer at the bony interface in a manner that does not inhibit the favourable properties of PEEK. This allows for easy radiographic visualisation for implant placement and fusion assessment while providing for a modulus more similar to bone.”
The first TiHawk7 procedure was performed by Micah Smith, an orthopaedic surgery specialist with Ortho NorthEast (Fort Wayne, USA). The two-level, percutaneous minimally invasive transforaminal lumbar interbody fusion (TLIF) procedure was completed with excellent results, say Accelus.
“I’ve performed several cases with the TiHawk7 to date and am very impressed with the endplate conformity of the interbody device, as well as the large amount of bone graft I am able to get in and around it,” said Smith. “I’m able to observe all of this radiographically through the TiHawk shell, which isn’t possible with other titanium expandable implants.”
The TiHawk7 device boasts an ultra-low insertion profile of 7mm tall by 7mm wide, and expands to form a 12mm tall by 11mm wide interbody footprint, say Accelus, who add that it also features instrumentation that allows for both comprehensive disc prep and direct visualisation of the disc prep for endoscopically assisted TLIF procedures. This allows surgeons to access the disc space through Kambin’s triangle to minimise the need for neural retraction and help preserve the patient’s normal anatomy.
Samuel Joseph, a fellowship-trained, board-certified orthopaedic surgeon and founder of the Joseph Spine Institute (Tampa, USA), also performed an endoscopically assisted, multilevel TLIF with TiHawk7. “TiHawk7 adds a new level of confidence to my minimally invasive procedures with its innovative application of titanium while reducing the risk of subsidence, delamination, or implant failure. I was able to perform the multilevel procedure endoscopically in three hours. The patient was sent home the day after surgery and is recovering well,” he said.
