An innovative shape memory alloy actuated cage has been developed for spinal fusion surgery. Spinal fusion surgery is performed on people suffering from low back pain. The viscoelastic spinal disc between the two vertebrae can degenerate in some fashion, such as herniation, and the space needs to be restored to relive the pressure on the nerves within the lower back. There are two main parts to a spinal disc, the annulus fibrosis and the nucleolus. The annulus fibrosis is a cartilaginous structure and is of interest to preserve. Therefore a minimally invasive cage utilizing superelastic elements has been developed. Furthermore, the cage safety and efficacy has been proven and will be presented here. Within this work, the efficacy and longevity of the cage will be presented. To this end, ASTM testing for spinal implants has been conducted on an electromechanical test system capable of inducing simultaneous axial and torsional forces.

In minimally invasive spinal fusion surgery, transforaminal lumbar (sacral) interbody fusion (TLIF) is one of the most common procedures that provides both anterior and posterior column support without retraction or violation to the neural structure. Direct and indirect decompression can be done through this single approach. Preoperative plain radiographs and MR scan should be carefully evaluated. This video demonstrates a standard approach for how to perform a minimally invasive transforaminal lumbosacral interbody fusion.The video can be found here: https://youtu.be/bhEeafKJ370.

Spinal Fusion Surgery

A prototype cage implant for spinal fusion surgery has been designed and developed. Spinal fusion surgery is sometimes performed to alleviate low back pain. The cage implant is a spacer that sits in between two vertebrae to allow for bone growth and fusion, all while relieving compression of the spinal cord. The cage implant is minimally invasive in nature, utilizing embedded nitinol hinges as dual purpose actuators and assembly structural elements. The cage implant utilizes elliptical shaped nitinol hinge pins as actuators to allow the cage to be in a straightened before deployment and manipulate its shape to an oblong octagon once within the disc space. A new modeling technique was developed to aid with the design of the nitinol ellipses. The model is MATLAB based and accounts for the non Mises behavior of nitinol through a correction factor for mapping the effective stress and strain. A nitinol rod and an elliptical geometry were examined experimentally and show the robustness of the developed model. These experiments were conducted to design the nitinol hinges for the cage implant. The cage implant is made of two different materials, nitinol hinge actuators and the containing titanium structural segments. The nitinol hinge actuators are completely enclosed within the medical grade titanium segments through the use of selective laser sintering.
