The North American Spine Society (NASS) 2023 conference, held in the vibrant city of Los Angeles, recently played host to spine specialists, medical device manufacturers, and healthcare enthusiasts from across the globe. Amid the bustling energy of the event,, a respected Med-Tech Innovation Report and journalism company sponsored by Ghost Productions Inc., had the privilege of engaging in an exclusive conversation with Todd Alamin, a representative from LimiFlex. This conversation shed light on LimiFlex's groundbreaking medical innovation, the Dynamic Sagittal Tether™, poised to usher in a new era in the treatment of degenerative spondylolisthesis.


LimiFlex, a distinguished medical device company, has unveiled the Dynamic Sagittal Tether™, a revolutionary, minimally invasive solution designed for patients suffering from degenerative spondylolisthesis. This condition, characterized by the forward slippage of one vertebra over another, frequently results in nerve compression, causing severe pain and debilitation. Traditionally, the primary treatment approach involved spinal fusion surgery, notorious for its invasiveness, cost, and potential complications.

The Dynamic Sagittal Tether™ presents a potential alternative to spinal fusion, and Todd Alamin provided insights into the genesis of this innovative device and its potential benefits for patients.

Todd Alamin elucidated that the initial concept behind the Dynamic Sagittal Tether™ aimed to restore the tension band in the spine's posterior region. However, it became evident that this approach held clinical promise in addressing various conditions, with degenerative spondylolisthesis being a key focus. This condition, characterized by vertebral slippage, often results in nerve compression, presenting a formidable challenge for both patients and physicians.

Conventional treatment in the United States involves fusion surgery, combining fusion with decompression to manage instability and nerve compression. LimiFlex embarked on a mission to offer a different approach to tackle this issue.

A Paradigm Shift for Patients

The effectiveness of the Dynamic Sagittal Tether™ hinges on two pivotal factors: the surgeon's ability to perform direct decompression to alleviate nerve pressure and the natural stability of the spinal segment when extended. While this device has already secured approval in Europe, it is currently under evaluation by the FDA for approval in the United States. To meet the stringent FDA requirements, LimiFlex conducted an exhaustive clinical trial involving 300 participants, spanning two years, with a control group undergoing lumbar fusion.

One of the most captivating aspects of the Dynamic Sagittal Tether™ is its capacity to preserve both motion and anatomy. It repositions the affected segment, engaging the facet joints, thereby establishing spinal stability without resorting to fusion. Todd Alamin shared that around two-thirds of patients in their clinical trial were able to return home on the same day, with 90% doing so within two days, underscoring the device's minimally invasive nature.

A Promising Future for Spinal Care

During the interview, Todd Alamin contemplated the potential longevity of the Dynamic Sagittal Tether™ and its potential to enhance patients' quality of life. While the device may not be suitable for young adults or those with immature skeletons, it holds promise for countless individuals grappling with degenerative spondylolisthesis.

Beyond preserving motion, LimiFlex's approach offers faster recovery times and outpatient procedures, in stark contrast to the prolonged hospital stays often associated with spinal fusion surgery. Furthermore, the device may play a role in mitigating the risk of adjacent segment degeneration, a recurring concern for fusion patients.

As the interview reached its conclusion, Todd Alamin's words resonated with the promise of LimiFlex: "The immediate benefit is how much faster patients recover and that it's an outpatient procedure. In the long term, we're potentially avoiding the annuity of adjacent segment degeneration that fusion patients often face."

With its potential to reshape the landscape of spinal care, LimiFlex's Dynamic Sagittal Tether™ stands as a beacon of hope for individuals grappling with degenerative spondylolisthesis, offering a brighter future in spinal health.
