[Treatment of lumbar spondylolisthesis by Socon internal fixator: report of 18 cases].

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.
