Anatomy-conserving spine surgery innovators Spineology has launched the Duo Angled Instrumentation System. The new developement is intended to supplement the Duo Lumbar Interbody Fusion System.
Using the system, surgeons will be able to address the L4-L5 disc space in cases where the iliac crest prevents collinear access.
The Duo System features an implant that combines PEEK, titanium, and graft containment mesh elements.
Post insertion, the implant is filled with bone and creates a large, endplate-conforming graft pack that expands up to 30mm in width to increase load-sharing and minimise point-loading.
Dr John Malloy IV from Florida said: “Compared to the traditional lateral systems I have used in the past, the design of the Angled Duo Portal Tube and supporting Angled Instrumentation makes these cases much easier as it allows me to quickly access the disc space, perform an efficient, thorough discectomy, and place an implant with significantly less retraction of the soft tissue and neural structures.”
Upon filling, the Duo Implant provides 70% more load-sharing surface area versus a 22mm width traditional lateral implant which has the same length.
These features of the Duo system have been designed to reduce subsidence, improve spinal correction maintenance, and support fusion.
Additionally, the system decreases the surgical access that is needed to place the implant and minimises the neural and soft tissue retraction typically required in these surgeries.
The Duo System will also reduce the retraction-related neurologic deficits that are commonly associated with the lateral approach.
The design of the Angled Duo Portal Tube also enables simple placement and proper positioning of the Portal Tube.
In October 2017, Spineology began the full market release of its Elite Expandable Interbody Fusion System which is inserted into the lumbar disc area at a contracted minimum height
