Abstract
Background. Aim of this prospective study was to evaluate safety and efficacy of second generation Wallis system for degenerative lumbar disc disease. Material and methods. 25 patients underwent discectomy and insertion of Wallis system. Outcome assessment was done using Modified Oswestry disability index (ODI) and visual analogue scale (VAS) for backache and leg pain. Results. The mean follow-up was 20.5 months. The mean VAS for backache and leg pain showed significant improvement from 7.2 to 3.0 (p<0.001) and mean modified Oswestry disability index showed significant improvement from 59.1 to 24.7 (p<0.001). Only one patient (4%) underwent revision surgery for persistent pain due to granulation tissue deep to the implant. There were no other complications. Conclusion. The Wallis spine system is a safe and effective implant for treating degenerative lumbar disc disease.<br/><br/>
