Abstract

Background: A prospective pilot study was designed to evaluate the role of a posterior dynamic stabilization technique in the surgical treatment of degenerative disc disease. Posterior dynamic stabilization with a hinged screw is a new concept in the surgical treatment of degenerative disc disease of the lumbar spine. The traditional surgical treatment is to apply a fusion procedure. However, numerous reports showed unsatisfactory clinical outcomes even when patients have satisfactory radiological outcomes following fusion procedures.

Material and Methods: The study included patients who were surgically treated with a dynamic stabilization technique due to painful degenerative disc disease. Clinical and radiological findings for the 20 participating patients were analyzed in a 2-year follow-up study. Preoperative and postoperative data at the 3rd, 12th and 24th month were collected for both clinical and radiological outcomes. Statistical analyses between preoperative and postoperative data were performed using the Wilcoxon test.

Results: The clinical outcome measurements (VAS, ODI) showed significant improvement in all postoperative measurements compared to preoperative values. The mean preoperative visual analogue score (VAS, 7.9) and Oswestry Disability Index (ODI 59.2) significantly decreased to 0.8 for VAS and 9.2 for ODI, at 2 years post-operation (p<0.05). The radiological studies showed no significant changes between pre- and postoperative values, in all parameters. There was no mortality or morbidity.

Conclusions: The results of this pilot study are encouraging. Dynamic stabilization may be an effective technique in the surgical treatment of painful degenerative disc disease. A larger series study, with longer follow-up periods and with control groups is needed to determine the success and safety of posterior dynamic stabilization in the surgical treatment of degenerative disc disease.
