The traditional treatment for degenerative lumbar spine, including discogenic low back pain, lumbar disc herniation, and lumbar spinal stenosis, is decompression and fusion surgery. Its efficacy is still good, but there are problems such as decreased mobility of lumbar vertebrae, degeneration of neighboring segments and broken nails and rods after surgery. In the last two decades, spinal non-fusion technology, also known as “Dynamic Stabilization System”, has emerged. Dynamic stabilization systems for the treatment of lumbar spine disorders currently include the pedicle nail-based dynamic stabilization system, the lumbar anterior interbody stabilization system (artificial lumbar disc and artificial nucleus pulposus), and the lumbar interspinous process (Interspinous process, ISP). The lumbar interspinous process (ISP) is a new type of spinal surgical instrumentation that combines biological research, biomechanical research, and material development based on past concepts, and has demonstrated its advanced concepts and broad application prospects since its introduction. Compared with the other two types of dynamic stabilization systems, the advantages of the lumbar ISP are: simple operation on the posterior column of the spine, simple operation, low surgical risk, and little interference with the normal structure of the spine. The Wallis system is a type of lumbar interspinous fixation system designed to consist of an interspinous cushion and two artificial ligaments made of polyester braided tape.The Wallis system was developed in 1984 by the French medical doctor Senegas. The first generation of the Wallis System began in 1986 with titanium interspinous pads, and the second generation improved them with polyether ether ketone (PEEK), which makes the interspinous pads more flexible.The Wallis System’s two artificial ligaments are used to encircle the spinous process, and there is an x-ray impermeable marker in the “ligaments,” which are anchored to the spinous process under certain tension. The ligaments are anchored to the spinous processes under a certain amount of tension. These artificial ligaments can withstand a tension of 2,000 N and can be lengthened by approximately 20% before overloading leads to failure. The entire system constitutes a “floating” device with no immobilization of the surgical segment and acts as an oscillation absorber while reducing the amount of flexion and rotation of the surgical segment. Senegas et al. retrospectively studied the clinical results of the first generation of the Wallis System in the treatment of degenerative lumbar spine disorders (including simple spinal stenosis, recurrent disc herniation, giant primary disc herniation, and spinal stenosis secondary to disc herniation) in 241 patients between 1987 and 1995, and 142 of them were followed up by telephone. The clinical results of 142 cases were followed up by telephone. The Wallis system was shown to be safe and effective in long-term use, possibly slowing down degeneration of adjacent segments, with efficacy at least similar to that of fusion surgery, and without fusion-related complications.Boerre et al. reported a multicenter prospective open study of the second-generation Wallis system in eight spine centers in six countries, confirming the efficacy and safety of the second-generation Wallis system in the treatment of degenerative lumbar disc disorders. The effectiveness and safety of the Wallis System in the treatment of degenerative lumbar disc disease was demonstrated. In terms of improvement in clinical symptoms, Senegas compared two similar groups of recurrent disc cases (40 cases each), Group A with disc removal only and Group B with disc removal + implantation of the first-generation Wallis System. Follow-up found significant improvement in both groups in terms of lower back pain, radicular pain, and Oswestry function scores, and Group B was superior to Group A. The authors suggested that the application of the Wallis System could be effective in relieving residual lower back pain and improving clinical function.
