2 Rigid, low-profile design ALIF system receives alpha release


Life Spine have announced that their Sentry plating system, which has been designed to improve lumbar stabilisation in anterior lumbar interbody fusion (ALIF) procedures, has been released in alpha.

The Sentry ALIF incorporates a cam-style locking mechanism that prevents unscrewing, with a low-profile and intuitive design for straightforward use by surgeons. The system is designed to eliminate the need for posterior stabilisation. To assist in guiding the plate for correct positioning, the device also includes an S1 anchor ledge for use in L5–S1 procedures.

Orthopaedic spinal surgeon Zeshan Hyder, (Bone and Joint Specialists, Merrillville, USA), said last year, “The Sentry lateral plate system is a key innovation … I am also able to achieve the ideal amount of fixation without having to use percutaneous screws.”

“Sentry ALIF’s low-profile design and multiple plate options [strengthens] Life Spine’s commitment to providing differentiated products to surgeons and their patients,” said Mariusz Knap, Life Spine’s vice president of Global Marketing and Business Development.

Life Spine, an Illinois-based company founded in 2004, develops biologics and spine surgery instrumentation, including for minimally invasive procedures. A release from the company yesterday said, “The low profile plate design [of the Sentry ALIF system] provides a rigidly stable construct without disturbing surrounding vasculature.”

The first cases with the system were performed in August 2016.

Life Spine is currently undertaking a study with the Oklahoma Spine and Brain Institute (Tulsa, USA) into the outcomes of spine surgery using its Nautilus thoracolumbar pedicle screw system and its Centerline thoracolumbar cortical screw system. The study will assess patient functional outcomes and muscular recovery using pre- and postoperative electrodiagnostic functional assessments (EFAs) and patient questionnaires.

Life Spine will be demonstrating their micro-invasive expandable technology at the North American Spine Society (NASS) annual meeting next week in Orlando, Florida, USA.
