Summary
The unipediculate approach for vertebroplasty effectively fills vertebral halves from one site, offering similar pain relief and radiographic outcomes to the bipediculate method.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
- Spinal Interventions
Background:
- Vertebroplasty is a common procedure for treating vertebral compression fractures.
- Standard bipediculate vertebroplasty involves two injection sites.
- A unipediculate approach offers a potentially less invasive alternative.
Purpose of the Study:
- To compare radiographic and clinical outcomes of unipediculate versus bipediculate vertebroplasty.
- To evaluate cement distribution and patient-reported pain relief.
Main Methods:
- Retrospective review of percutaneous vertebroplasties.
- Comparison of 57 vertebrae (unipediculate) and 18 vertebrae (bipediculate).
- Radiographic analysis of cement opacification and statistical comparison of clinical outcomes.
Main Results:
- Unipediculate approach achieved midline cement filling in 96% of cases.
- No significant difference in mean vertebral body opacification (83% vs. 77%, P=.19).
- Similar adequate pain relief rates (94% vs. 88%, P=.65) and pain reduction.
Conclusions:
- The unipediculate approach allows effective bilateral cement filling from a single puncture.
- Clinical outcomes are comparable to the standard bipediculate approach.
- Unipediculate vertebroplasty is a viable alternative with similar efficacy.
