Abstract:
Objective To evaluate the early effect of Wallis interspinous dynamic stabilization system (Wallis system) in treatment of lumbar degenerative disease. Methods From January 2008 to Jan-uary 2009,21 patients(23 intervertebral spaces) with early lumbar disc herniation and lumbar spinal stenosis were treated with Wallis system. Four intervertebral spaces of L_(3-4) 19 intervertebral spaces of L_(4-5). Observed the time of total operation and implantation,the blood loss,and early recovery. The patients' visual analogue scale (VAS) and Oswestry disability index (ODI) scores were evaluated before and after operation. Results All patients were followed up for average (12.5 ± 0.4) months (7-18 months) after operation. The VAS and ODI scores at 7 days after operation dropped from (7.5 ± 1.5), (40.0 ± 2.0) scores before operation to (2.5 ± 0.5), (23.0 ± 1.5) scores (P < 0.01). Conclusion It is safe and easy to use Wallis system in the treatment of lumbar degenerative disease, with the advantage of mini-invasion and early effect.
