First surgical use of TheraFuze DBF Fiber Bullets in an interbody TLIF cage


TheraCell has announced the first surgical use of TheraFuze DBF Fiber Bullets. According to a press release from the company, the DBF Fiber Form is designed for minimal access delivery into expandable cages, revisions and other surgical applications.

TheraCell reports this case was performed by Neel Anand (Cedars Sinai Medical Centre, Los Angeles, USA), on an L3–L4 PSF with interbody transforaminal lumbar interbody fusion (TLIF) at L3–L4 and using several TheraFuze DBF Fiber Bullets to fill the interbody space, as well as TheraFuze DBF Fiber Form combined with autograft in the cage.

Anand commented, “After discectomy and endplate preparation to accept the TLIF cage, I placed several Fiber Bullets in the lyophilised state anterior to the implant to fill the interbody space with graft material. Subsequent to the cage insertion, several additional Fiber Bullets were placed posterior to the cage to ensure complete endplate-to-endplate apposition of the TheraFuze DBF allograft in the interbody. I placed 1cc of DBF FiberForm combined with autograft in the lumen of the TLIF cage.” Additionally, he stated, “Delivery of the bullets through a cannula is a very convenient option. The entire procedure was quite simple and fit into my usual surgical process with ease.”

The company states that the TheraFuze DBF Fiber Bullets are made from cortical demineralised bone fibers, processed using TheraCell’s proprietary and patented technologies. TheraCell adds that these processes have been developed to produce uniform fiber geometry, size and texture, and to preserve the natural collagen structure of the allograft, providing surgeons with a 100% natural allograft that is osteoconductive with osteoinductive potential and enhanced handling properties ideal for spinal fusion and other orthopaedic applications.
