Encouraging Medium-term Results of Wallis Second Generation Dynamic Stabilisation Device

Area of Science:

• Spine surgery
• Orthopedic technology
• Degenerative disc disease

Background:

• Degenerative lumbar disc disease is a common cause of back pain.
• The Wallis system is a spinal implant designed for intervertebral disc stabilization.
• Evaluating newer generation implants is crucial for improving patient outcomes.

Purpose of the Study:

• To assess the safety and efficacy of the second generation Wallis system.
• To evaluate the system's performance in patients with degenerative lumbar disc disease.

Main Methods:

• A prospective study involving 25 patients.
• Patients underwent discectomy and Wallis system implantation.
• Outcomes measured using the Modified Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) for pain.

Main Results:

• Significant improvement in VAS scores for backache and leg pain (7.2 to 3.0, p<0.001).
• Significant improvement in Modified Oswestry Disability Index (59.1 to 24.7, p<0.001).
• Only one patient (4%) required revision surgery for implant-related complications; no other adverse events were noted.

Conclusions:

• The second generation Wallis system is a safe and effective treatment option.
• The implant demonstrates positive outcomes for patients suffering from degenerative lumbar disc disease.
