Retrospective Image Analysis of Degenerative Lumbar Disease Patients

NCT04886557 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 139

No results posted yet for this study

Summary

The Dynesys dynamic stabilization (DDS) system is considered a motion-preserving device. However, studies addressing the change in the range of motion (ROM) are limited. Therefore, this study aimed to investigate the factors influencing ROM change at the index surgical level, supra-index level, and whole lumbar spine, in addition to the association between ROM preservation and the incidence of screw-loosening.

Conditions

  • Lumbar Spondylolisthesis

Interventions

PROCEDURE

L4-L5 decompression and dynamic instrumentation

All surgeries were performed by a senior surgeon using a traditional midline approach. Stability-preserving lumbar decompression with facet joint undercutting was performed to preserve the facet joints as much as possible. In cases of severe stenosis, a bilateral partial facetectomy (\< 25%) was performed for adequate decompression. Posterior tension of the supra- and inter-spinous ligaments was preserved at the most cranial level. Patients were encouraged to ambulate after drain removal and wear a soft lumbar orthosis for at least 3 months after the operation.
