RF-TVA™ Case Studies
The following case studies focus on Radiofrequency-Targeted Vertebral Augmentation™ (RF-TVA™) with the StabiliT® Vertebral Augmentation System.
Case 1
Spine region: Lumbar
Physician: Jay Patel, MD
Title: Interventional Radiologist
Hospital: Baylor Medical Center, Irving, Texas
Patient gender: Female
Patient age: 82
Level(s) treated: L1
Age of fracture(s): Less than one week
Pathology: Osteoporosis
X-ray images:
Results
The patient was 100% pain free after the procedure and walked out of hospital after a short stay. Prior to the procedure, Visual Analogue Scale (VAS) scores were 8 and 9 (out of 10) while resting and standing, respectively.
Case 2
Spine region: Lumbar
Physician: Ron Adelman, MD
Title: Interventional Radiologist
Hospital: Aria Health, Philadelphia, PA
Patient gender: Female
Patient age: 76
Level(s) treated: L1
Age of fracture(s): 6 weeks
Pathology: Osteoporosis
X-ray Images:
| Pre-op Lateral |
|
 |
|
| Intra-op Lateral |
|
 |
|
| Intra-op AP |
|
 |
|
| Via a unipedicular approach, the VertecoR® StraightLine Osteotome creates an initial cavity and access to the anterior aspect of the vertebral body. |
| Intra-op AP |
|
 |
|
| Targeted inferior channel across midline to the level of contralateral pedicle created with the VertecoR® MidLine Osteotome |
| Intra-op Lateral |
|
  |
|
| Targeted channel into superior anterior 1/3 created with the VertecoR® MidLine Osteotome |
| Intra-op AP |
|
 |
|
| Ipsilateral channel created to optimize cement flow into the ipsilateral third of the vertebral body |
| Post-op Lateral |
Post-op AP |
 |
 |
| Controlled and preferential cement flow results in cement across the midline and site-specific delivery into the superior comminuted areas. |
Results
Targeted cavity creation, optimal cement fill and fracture stability and patient 100% pain free. Patient walked out of the hospital 3 hours post-procedure.
Case 3
Spine region: Thoracic
Physician: Keith Kortman, MD
Title: Interventional Radiologist
Hospital: Sharp Memorial Hospital, San Diego, California
Patient gender: Male
Patient age: 64
Level(s) treated: T4, T5
Age of fracture(s): 6-8 weeks
Pathology: Osteoporosis
X-ray Images:
| Intra-op Lateral |
Intra-op AP |
 |
 |
| Unipedicular placement of the StabiliT Introducer |
   |
| Superior and inferior cavity creation using the VertecoR MidLine Osteotome in T5. The VertecoR MidLine Osteotome also enabled creation of a targeted channel across the midline of the vertebral body. |
 |
 |
| Site-specific delivery of StabiliT ER2 Bone Cement |
Results
Dr. Kortman was very pleased with the results and flexibility of the StabiliT System while performing RF-TVA. Cement flowed nicely into the targeted channel in T5 created by the VertecoR MidLine Osteotome. It moved into the superior fracture plane and began to interdigitate into native trabecular bone toward the inferior endplate.
