Performance and Safety of Joline® Kyphoplasty Single Balloon Catheter Allevo vs. Quattroplasty Double-Balloon Catheter Stop'n GO With BonOs® Inject Bone Cement

Evaluation of Surgical Therapy of Vertebral Compression Fractures With the Kyphoplasty Single Balloon Catheter Allevo (Joline®) and the Quattroplasty Double Balloon Catheter Stop'n GO (Joline®) With BonOs® Inject Bone Cement

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.

Study Overview

• Status: Unknown
• Conditions: Vertebral Compression Fracture
• Intervention / Treatment: Device: Kyphoplasty Single Balloon Catheter Allevo; Device: Quattroplasty Double Balloon Catheter Stop'n GO

Detailed 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.

Description

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

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in vertebral body height	Change in vertebral body height	pre-operative, 5 days and 3 months post-operatively
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
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 Outcome Measures

Outcome Measure	Measure Description	Time Frame
Safety Outcomes: Occurence of adverse events and complications	Occurence of adverse events and complications	during procedure, 5 days and 3 months post-operation
