Kern Singh, Midwest Orthopaedics at Rush University Medical Center, and his team have started to enrolĀ patients for a clinical study on the FLXfit articulating and lordotic expandable cage (Expanding Orthopedics).

Singh, associate professor, Rush University Medical Center, co-director Minimally Invasive Spine Institute, has an international reputation in the area of minimally invasive spinal surgery. He says that ā€œminimally invasive surgery is one of the biggest trends in spine fusion procedures, but still encompasses many challenges, one of which is delivering a large footprint cage into the disc space through a small tube.ā€ Singh added that ā€œthe anatomy of the lower disc spaces, representing 80% of the procedures, adds further challenges of limited access as well as lordosis correction/restoration needs. Achieving that with a single implant through a minimally invasive access is a major undertaking.ā€

Singh explains, ā€œBased on my initial experience with the FLXfit cage, it is easily inserted through a minimally invasive TLIF technique, as it is initially delivered as a straight cage and can be articulated inside the disc space creating a ā€œbanana-like shapeā€. He thinks that ā€œthis enables the surgeons to reach an optimal midline and anterior position. The unique lordotic expansion enables us to dial-in the patient-specific angle correction.ā€

Singh concludes, ā€œWe believe that the clinical study will provide further understanding of the clinical benefits of a lordotic expandable cage and the short- and long-term impact on the global and lumbar lordosis.ā€
