Summary
Prone-transpsoas single-position corpectomy (PTP-corpectomy) is a safe and effective technique for complex spinal pathologies. This approach offers simultaneous spinal access, improving patient outcomes and stability.
Area of Science:
- Spine Surgery
- Orthopedics
- Neurosurgery
Background:
- Prone-transpsoas (PTP) corpectomy is an emerging technique for spinal surgery.
- It allows simultaneous lateral and posterior spinal access without repositioning the patient.
- Existing literature primarily details the PTP approach for interbody fusions, with limited evaluation for corpectomy.
Purpose of the Study:
- To describe the surgical technique of PTP-corpectomy.
- To report early clinical outcomes for complex thoracolumbar spinal pathologies.
- To contribute to the limited case volume on PTP-corpectomy.
Main Methods:
- Retrospective review of seven patients undergoing PTP-corpectomy.
- Indications included severe kyphoscoliosis, traumatic burst fractures, and revision surgery.
- Data collected: demographics, comorbidities, surgical history, perioperative details, radiographic imaging, and clinical outcomes.
Main Results:
- All seven patients successfully underwent PTP-corpectomy.
- Average operative time: 460.6 minutes; average EBL: 892.9 mL.
- Average postoperative LOS: 6.7 days; all patients showed improved pain and function.
Conclusions:
- PTP approach is feasible, safe, and effective for corpectomy in complex spinal pathologies.
- The technique demonstrates positive clinical outcomes.
- Further studies with larger cohorts are needed to validate findings.
