Summary
Posterior vertebral column resection effectively treats severe spinal deformities. This single-approach technique corrects deformities but carries risks, requiring careful patient selection and surgical expertise.
Area of Science:
- Orthopedic Surgery
- Spinal Deformity Correction
- Surgical Techniques
Background:
- Vertebral column resection (VCR) is a complex procedure for severe, inflexible spinal deformities.
- Traditional anterior-posterior VCR poses significant challenges.
- A single posterior approach technique was developed to improve upon existing methods.
Purpose of the Study:
- To present a novel technique for vertebral column resection (VCR) using a single posterior approach.
- To evaluate the preliminary outcomes of this technique in treating moderate to severe spinal deformities with limited flexibility.
Main Methods:
- A retrospective review of 70 patients undergoing posterior VCR for spinal deformities.
- Patients had a minimum 2-year follow-up.
- The technique involved pedicle screw fixation, posterior VCR at the deformity apex, gradual correction, and fusion.
Main Results:
- Achieved 61.9% coronal and 45.2-degree sagittal plane deformity correction.
- Average operative time was 4 hours 31 minutes with 2333 mL blood loss.
- Complications occurred in 24 patients, including 2 complete cord injuries, hematomas, root injuries, fixation failures, infections, and hemopneumothoraxes.
Conclusions:
- Posterior vertebral column resection (VCR) is an effective treatment for moderate to severe spinal deformities with limited flexibility.
- The procedure is technically demanding and associated with significant potential complications.
- Careful patient selection and surgical skill are crucial for successful outcomes.
