| Abstract |
Objective: Symptomatic lumbar degenerative disc disease is a challenging entity to treat. Total disc replacement has numerous potential advantages to provide long-lasting relief to these patients, as well as the avoidance of pseudarthrosis, and the develop- ment of junctional degeneration. The purpose of this study was to present the preliminary clinical results following a Prodisc total lumbar disc replacement.
Methods: Twenty-five patients had single or multiple-level implantation of a total lumbar disc replacement. The subjects were 9men and 16women, with a mean age of 43 years, ranging from 29 to 53. The mean follow-up duration was 11 months, ranging from 6 months to 20 months. Clinical results were evaluated based on the criteria proposed by Yuan et al. Each patient completed a survey that measured pain(back and leg pain separately) and functional outcomes. The Oswestry Disability Index was also assessed.
Results: Seventeen(77%) of the 22 patients, who had leg pain preoperatively, achieved our definition of successful outcomes. Preoperatively, all patients had significant back pain, while postoperatively 92% of patients(n=25) achieved successful outcomes with regard to their back pain. Finally, functional improvement occurred in 88% of patients(n=25). The mean preoperative ODI was 53.0±10.0. At postsurgery one month, 6 months, 12 months, and last follow up visit, the mean ODI decreased to 36.1±11.2, 28.4±8.2, 23.2±7.7, and 21.8±8.7, respectively. There were significant improvements(p<0.001) in the Oswestry Disability Index. Radiographs did not demonstrate loosening, migration, or mechanical failure in any patient. Five patients had approach-related complications.
Conclusions: The Prodisc lumbar total disc replacement appears to be effective and safe for the treatment of symptomatic degenerative disc disease. The authors believe that longer follow-up of this cohort of patients are needed to determine the effi cxcy of total disc replacement in selected patients with symptomatic degenerative disc disease. |
