Summary
For patients with caudal spine absence, using two pairs of pelvic screws for spinopelvic fixation is more reliable long-term than a single pair, reducing non-fusion risks.
Area of Science:
- Orthopedic surgery
- Spinal deformity correction
- Pediatric spine surgery
Background:
- Caudal spine absence presents complex challenges in spinal deformity management.
- Spinopelvic fixation is crucial for stabilizing the spine in these patients.
Purpose of the Study:
- To compare the outcomes of single versus double pelvic screw techniques in patients with caudal spine absence.
- To evaluate the efficacy and complication rates of different pelvic screw configurations.
Main Methods:
- A cohort of 22 patients with varying degrees of caudal regression underwent spinal surgery.
- Surgical interventions included spinal stabilization with scoliosis/kyphosis correction using one or two pairs of pelvic screws.
- Patients were followed for over two years post-surgery.
Main Results:
- Significant improvements in scoliosis and kyphosis were observed post-surgery.
- No significant short-term complications differed between single and double screw groups.
- Long-term non-fusion complications were more frequent with single pelvic screw fixation.
Conclusions:
- Spinopelvic fixation effectively improves spinal deformities in caudal spine absence.
- Implanting two pairs of pelvic screws offers greater long-term reliability and reduces non-fusion rates compared to a single pair.
