Summary
This study demonstrates that a ventral surgical approach effectively corrects postoperative cervical kyphosis, restoring lordosis and improving patient symptoms. The technique shows sustained correction and positive clinical outcomes in most patients.
Area of Science:
- Neurosurgery
- Spine Surgery
- Orthopedics
Background:
- Cervical kyphotic deformity can arise post-surgery from ventral or dorsal approaches.
- Preventing or correcting cervical kyphosis is crucial for patient outcomes.
Purpose of the Study:
- To describe a ventral surgical technique for correcting iatrogenic cervical kyphosis.
- To evaluate the efficacy and outcomes of this ventral approach.
Main Methods:
- Retrospective review of 12 patients undergoing ventral correction of postoperative cervical kyphosis.
- Procedure involved specific head positioning, distraction pins, and a ventrally placed implant.
- Pre- and postoperative sagittal angles and clinical status were assessed.
Main Results:
- Mean deformity correction achieved was 20 degrees of lordosis.
- Mean postoperative sagittal angle was 6 degrees of lordosis.
- Mean sagittal angle change during follow-up was 2.2 degrees of lordosis.
Conclusions:
- The ventral approach successfully achieved lordosis in most patients, with sustained correction.
- All patients showed postoperative improvement, with three experiencing complete symptom resolution.
- Ventral correction is an effective option for symptomatic postsurgical cervical kyphosis.
