Clinical Trial Summary

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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in vertebral body height	Change in vertebral body height	pre-operative, 5 days and 3 months post-operatively
Primary	Change in Visual Analog Scale (VAS) of subjective pain	The Visual Analog Scale (VAS) is a measure for pain intensity. The score of the sclae ranges from 0 for "no pain" to 10 for "worst imaginable pain". Patients will report their pain at baseline and at 2 dedicated periods to assess change in pain intensity.	pre-operation, 5 days and 3 months post-operation
Primary	Change in functional disability	The Oswestry Disability Index (ODI) is used to assess functional disability. The questionnaire consists of 10 items with each item having 6 statements. All scores are summed, then multiplied by two to obtain the index (range from 0 to 100) with higher score indicating greater disability.	pre-operation, 5 days and 3 months post-operation
Secondary	Safety Outcomes: Occurence of adverse events and complications	Occurence of adverse events and complications	during procedure, 5 days and 3 months post-operation
