Summary
This study on spinal internal fixators found good or fair clinical results in 88% of patients, with a low rate of significant complications. The fixator shows potential for spinal deformities but may require combined stabilization for severe spondylolisthesis.
Area of Science:
- Orthopedics
- Spinal Surgery
- Biomedical Engineering
Background:
- Spinal deformities and instability pose significant clinical challenges.
- Internal fixators are increasingly used for spinal stabilization.
Purpose of the Study:
- To evaluate the clinical outcomes and complications of an internal fixator in spinal surgery.
- To assess the efficacy of internal fixators for various spinal conditions.
Main Methods:
- Retrospective analysis of 59 consecutive patients undergoing spinal surgery with internal fixators.
- Minimum 2-year follow-up for 51 patients.
- Categorization of diagnoses including mechanical instability, deformity, infection, or tumor.
Main Results:
- 88% of patients achieved good or fair clinical results.
- Low rates of pseudarthrosis (2), postoperative infection (1), and neurological complications (3).
- Asymptomatic hardware failures (13 screws, 1 rod) did not necessitate revision surgery.
Conclusions:
- The internal fixator provides satisfactory stability, promotes fusion, and yields good clinical results with minimal relevant complications.
- It demonstrates significant potential for correcting scoliotic and kyphotic deformities.
- Severe spondylolisthesis may require combined anterior and posterior stabilization for optimal outcomes.
