About

The purpose of this study is to assess the performance and safety of two balloon kyphoplasty systems (Joline®), the single balloon catheter Allevo and Quattroplasty double balloon catheter Stop'n Go, using BonOs® Inject bone cement for treatment of Vertebral Compression Fractures.

Full description

Vertebral compression fracture (VCF) is a very common medical problem and describes the collapse of a vertebral body (VB) in the spine. VCF can lead to severe pain, decreased physical function, spinal deformity and in rare cases thoracic or abdominal wall deformities, that can impair pulmonary and gastrointestinal function. A VCF can occur in patients with healthy spines upon severe trauma, in patients suffering from osteoporosis or in patients with metastatic tumors.

Currently available therapy for VCF includes medical management, surgical treatments and vertebral augmentation (VA). Medical management consists of bed rest followed by early mobilization and analgesic medications. Surgical options include spinal stabilization with rods and screws. VA procedures attempt to stabilize the spine and reduce vertical compression by adding material to the spine.

Kyphoplasty is a commonly performed VA procedure. In kyphoplasty, a surgical instrument is used to reduce the collapsed VB towards its original shape. Reduction of the fractured VB is thought to be beneficial since (1) it may reduce anterior directed compressive forces resulting from kyphosis of the spine due to the fracture, and (2) it may reduce some physiologic abnormalities due to kyphosis, such as restrictive lung disease or abdominal compression. After fracture reduction, bone cement is placed in the VB to stabilize the reduction. Fracture reduction follows the orthopedic general principles of fracture repair: reduction and stabilization.

Primary objective of this observational study is to compare the effectiveness of the Quattroplasty double balloon catheter Stop'n GO (Joline®) with the Kyphoplasty single balloon catheter Allevo (Joline®) combined with BonOs® Inject bone cement for use in VCF reduction, to confirm the performance of those two devices and to investigate potential major adverse events associated with the use of the device in patients treated in a controlled setting when used according to the IFU. Secondary objective is to compare the safety of the Quattroplasty double balloon catheter Stop'n GO (Joline®) with the Kyphoplasty single balloon catheter Allevo (Joline®) combined with BonOs® Inject bone cement.

Inclusion criteria

patients aged ≥18 years
1-3 painful VCF(s), of which at least 1 meets the following criteria:
- VCF between T7 and L5
- Fracture age <3 months
- VCF shows hyperintense signal on STIR or T2 sequence MRI.
Investigator estimates that target VB(s) is/ are suitable for Quattroplasty double balloon catheter or Kyphoplasty single balloon catheter (e.g. appropriate pedicle diameter, no cortical bone protruding into the spinal canal).
Patient has an ODI score of 30% or more.
Patient is willing and able to comply with study requirements.
Patient signs informed consent form.
Women who are post-menopausal, surgically sterile or on contraceptives and agree to remain on contraceptives for the duration of their study participation and agree not to become pregnant during the study.

Exclusion criteria

Segmental kyphosis of target VB of >30°
Pre-existing or clinically unstable neurologic deficit
Any physical exam evidence of myelopathy or radiculopathy
Not able to walk without assistance prior to fractures
Any radiographic evidence of pedicle fracture or interspinous-process widening
Spondylolisthesis >grade 1 at target VB(s)
History of spine surgery, including prior vertebral augmentation, during the last year
Any underlying systemic bone disease other than osteoporosis (e.g. osteomalacia, osteogenesis imperfect, etc.)
Irreversible coagulopathy and/or taking peri-operatively warfarin (Coumadin) or other anticoagulant
Pregnancy and nursing
Pain due to any other condition that requires daily narcotic medication
Disabling back pain due to causes other than acute fracture
History of intolerance, or allergic reaction to titanium or acrylic compounds
Active systemic or local infection at baseline
Severe cardiopulmonary disease (e.g. stage IV heart failure, severe chronic obstructive pulmonary disease)
Any other medical illness or condition that, in the investigator's opinion, is likely to impair long-term follow-up (e.g. cancer) or greatly increase the risk of surgery
Any evidence of substance abuse
The patient is on long-term steroid therapy (steroid dose 30 mg/day for >3 months)
The patient is known to be involved in medical litigation including Workmen's compensation.
Patient with contraindication for MRI including but not limited to patients with contraindications for general anesthesia (surgeon expertise)
Patient who is contraindicated for the use of PMMA cement
Patients who belong to a vulnerable population or that are not able to sign the informed consent form.
Patients where the VCF was treated in combination with fusion.
Patients with any contraindication according to the IFU
