Objective: To evaluate the therapeutic effect of Socon transpedicle internal fixators in the treatment of spondylolisthesis in the lumbar spine.
Methods: Fixation with Socon internal fixators along with posterior decompression and fusion was performed in 18 patients with degenerative spondylolisthesis in the lumbar spine. The symptoms, signs and X-ray manifestations observed preoperatively and postoperatively were compared, and a follow-up study of all cases lasting for 6 to 18 month was conducted.
Results: Anatomical restoration of the involved vertebrae was achieved in all the cases, of them 15 had out-standing and 2 had fairly good clinical results without incidences of any complications during or after the operation.
Conclusion: Socon internal fixator is an excellent modality for treatment of lumbar spondylolithesis.
