Out of the ten winning companies with the Orthopaedics This Week’s BEST new spine care technologies for 2016, two are Edge Medical Partners and we are delighted to be working with such outstanding and peer recognised organisations!
The first is Lifespine with the Longbow Expandable Lateral Spacer System which expands laterally, (anterior/posterior) in situ specifically for a direct lateral approach.
The second is Spineguard with The DSG™ Screw which is a pedicle screw system with a breach anticipation sensor located at the tip of the screw.
Full details below.
Life Spine – Winning Technology: LONGBOW®
Category: Minimally Invasive Spine Care
Inventors: Michael Butler, Dan Predick
The innovative LONGBOW Expandable Lateral Spacer System expands laterally, (anterior/posterior) in situ specifically for a direct lateral approach. The benefits of LONGBOW are transferred directly to the patient by offering a custom fit and minimizing tissue retraction and potential nerve damage associated with the lateral access approach.
LONGBOW is inserted at a smaller width compared to a traditional static lateral interbody and is then expanded posteriorly in-situ for a custom fit and maximum coverage of the disc space. It can be filled post-expansion with approximately three times as much bone graft as compared to the average graft volume of a static lateral interbody.
LONGBOW was the first FDA cleared laterally expanding interbody for lateral access. It was received Becker’s 2015 Spine Device Award.
In the lateral approach, surgeons may dissect the psoas muscle in order to access the disc. Nerve damage is a concern since lumbar plexus nerves lie in the posterior one-third of the psoas muscle.
Fixed width lateral implants require the surgeon to dock the retractor posteriorly and closer to the nerves of the lumbar plexus and then retract the muscle significantly to fit a specific implant width into the disc.
By contrast, LONGBOW is inserted anteriorly, away from the nerves, at a smaller width and then expanded in-situ for a custom fit to the patient with minimal muscle retraction. This minimally invasive approach decreases the overall muscle and tissue retraction, potentially reducing tissue and nerve damage and post-operative recovery times.
When compared to static interbody cages, about three times the bone graft can be inserted post-expansion into LONGBOW.
By redefining the surgeon’s starting position for lateral access spine surgery, increasing the amount of bone graft used and minimizing the risk of nerve damage, LONGBOW is a significant technological advancement.

The DSG™ Screw is a pedicle screw system with a breach anticipation sensor located at the tip of the screw.
This gives surgeons real-time screw guidance and the ability to insert directly into the pedicle without drilling a pilot hole.
It is the unique merger the DSG™ technology (Dynamic Surgical Guidance) bipolar sensor with a pedicle screw—in one device.
The DSG™ sensor differentiates various tissue types based on the analysis of the local electrical conductivity (cancellous bone, cortical bone, blood and soft tissues). Real-time feedback informs the surgeon of changes in tissue type by changes in the pitch and cadence of an audio signal and a flashing LED light. This in turn alerts the surgeon of potential pedicular or vertebral breaches during pedicle screw placement in both traditional and MIS settings.
Moreover, the use of the DSG screw in MIS obviates the need for a k-wire. The result is single-step pedicle screw insertion with an unprecedented degree of accuracy and reduced radiation exposure.
According to the National Institute for Health and Care Excellence, “the main risk associated with placing pedicle screws is pedicle perforation, which occurs when the screw exits the vertebrae. This can result in dural tears, vascular injury, nerve injury or, rarely, spinal cord injury.”
The DSG™ Screw improves pedicle screw placement success rates and lowers radiation exposure for the patient, surgeon, and OR staff. It can also increase workflow efficiency since the DSG Screw system allows for direct insertion of the screw in the pedicle without prior drilling of a pilot hole and decreases K-wire usage.
In short, higher quality of care while saving time and costs.
