Extent of pain relief and vertebral height gain were found to be similar with both procedures [ ]. They compared the efficacy of this new procedure with kyphoplasty in cadaveric samples, and found substantially less height reduction when compared to kyphoplasty [total anterior height gain — kyphoplasty: Patients were randomly divided into 2 groups: However, the selection of application of procedures was notably biased, with more severe VCFs receiving kyphoplasty. Footnotes Source of support: Percutaneous vertebroplasty compared with optimal pain medication treatment: Few new generation bioactive bone cements have been found to induce new bone formation and also have good mechanical stability.

A Comparison and Contrast. To minimize the infection, antibiotics are sometimes added to the cement mixture before injection by clinicians [ 4 , 26 ]. Eighty-four percent of patients had substantial or complete pain relief with a short mean follow-up of 4. Radiofrequency kyphoplasty — an innovative method for the treatment of vertebral compression fractures — comparison with conservative treatment. The superiority of these procedures still remains a subject of debate.

Percutaneous vertebroplasty for spinal metastases: Percutaneous vertebroplasty versus balloon kyphoplasty for treatment of osteoporotic vertebral compression fracture: Curr Rev Musculoskelet Med.

Extravasation of bone cement into epidural spaces leads to more serious complications. Interventional neuroradiologists in the US began using this technique in and the first case series was published in [ 4 ]. Direct comparison in terms of efficacy of PV and PK is not possible as there is no randomized control trial. Bone cement is an implant biomaterial, which should be biocompatible.

Effects of low doses of strontium on bone quality and quantity in rats. Is there a stable vertebral height restoration with the new radiofrequency kyphoplasty? A small amount of inhibitor, typically hydroquinone, is also added to the liquid phase to avoid premature polymerization [ 19 ].

Clinical outcomes after acute osteoporotic vertebral fractures: CT-guided vertebroplasty and kyphoplasty: These 2 procedures differ mainly in the surgical techniques used.

Hyperthermia-induced damage to ratsciatic nerve assessed in vivo with functional methods and with electrophysiology. The review examines the outcomes of vertebroplasty and kyphoplasty procedures.

Mark Reiley, an orthopedic surgeon, introduced the idea of inserting an inflatable balloon tamp into the VB to elevate or expand the vertebra to its original height. Strontium is radiopaque and it has also been shown to induce new bone formation and to inhibit bone resorption in vitro and in vivo [ 50 — 53 ]. No balloons are required — after creating an incision on the skin, a g introducer is inserted into the middle third of the vertebral body.

Improved vertebral height restoration with PK is also controversial, because initial height gain is higher in kyphoplasty but this effect is lost subsequently during balloon deflation and repetitive loading.

Risk of new vertebral fracture in the year following a fracture. In kyphoplasty, a bone tamp is inserted to create a cavity before injecting the bone cement, while this Nitinol implant-based obne involves the placement of the implant inside the vertebral body after making the pathway for the implant by using a coaxial manual drill.


Seppalainen Verfebroplasty, Rajaniemi R. In vivo evaluation of calcium sulfate as a bone graft substitute for lumbar spinal fusion. The extent of cement leakage depends on the cause of the VCFs. Therefore, the Nitinol implant is safe and effective for vertebral augmentation, and it provides long-lasting pain relief and persistent vertebral height gain [ ]. The higher intravertebral pressure is associated with higher cemrnt rate and size of the cannula.

They carried out a randomized study on 34 patients with painful osteoporotic VCFs.

An in vivo comparison of the potential for extra vertebral cement leak after vertebroplasty and kyphoplasty. Effect of strontium chloride on bone resorption induced by prostaglandin E2 in cultured bone.

This novel procedure involves targeted delivery of radiofrequency RF -activated, warm, highly viscous bone cement PMMA using an cenent osteotome. A small incision is made to insert the inch cannulated trocar and biopsy needle. The cemented nitinol implant restored the vertebral height even after 1 year, but substantial height loss was observed with PV and PK.
