VERTEBROPLASTY BONE CEMENT THESIS

Radiofrequency-targeted vertebral augmentation versus traditional balloon kyphoplasty: J Spinal Disord Tech. Hyperthermia-induced damage to ratsciatic nerve assessed in vivo with functional methods and with electrophysiology. Both PV and PK should be performed by a clinician with in-depth knowledge of spinal anatomy and fluoroscopy imaging. PV and KP are the most routinely used minimally invasive procedures to treat osteoporotic or tumor-associated VCFs with the primary aim of relieving pain. Clinical outcomes after acute osteoporotic vertebral fractures:

Future Developments Vertebroplasty and kyphoplasty are both excellent percutaneous interventions in providing short-term pain relief and improved physical functionality. Few new generation bioactive bone cements have been found to induce new bone formation and also have good mechanical stability. However, there is a debate over the cause of the new compression fracture. The patients in the control group went through the preprocedural steps similar to the steps for the PV group e. Early histologic changes following polymethylmethacrylate injection vertebroplasty in rabbit lumbar vertebrae. Augmentation of osteoporotic vertebralbodies. Kyphoplasty History The first percutaneous vertebroplasty was performed in by Gakibert and Deramond, interventional neuroradiologists in Amiens, France.

The main idea behind developing the kyphoplasty procedure was to restore vertebral body height and minimize the associated kyphotic deformity by inserting an inflatable balloon inside the vertebral body before injecting the bone cement. In Vertebrkplasty the balloon is taken out before injecting the bone cement, while the Nitinol implant remains inside to further reinforce the VB. General anesthesia or monitored anesthesia is used.

There are few reports in which these procedures have been performed to treat conditions such as severe vertebral body collapse, burst fracture, or cervical spine disease [ — ]. The spinal level of the patient is verified by preoperative imaging and image intensifier before placing any cannula or syringe. Thus the immediate pain relief after PV or PK can easily vertebroplassty related to the cessation of vertebrop,asty cleft motion after curing of the bone cement.

Therefore, VBS can be considered as a promising candidate for vertebral augmentation. Percutaneous vertebroplasty and kyphoplasty for painful vertebral body fractures in cancer patients.

In case of monitored anesthesia, the anesthetist should generously inject local anesthesia, especially into the periosteum, as some patients feel discomfort during the advancement of the trocar through the posterior cortical margin with balloon inflation in case of kyphoplasty and with injection of cemen cement.

Abstract Percutaneous vertebroplasty PV and kyphoplasty PK are the 2 vertebral augmentation procedures that have emerged as minimally invasive surgical options to treat painful vertebral compression fractures VCF during the last 2 decades. The ideal material for use vertebgoplasty vertebroplasty should have a longer liquid phase working time and shorter set time, whereas material with shorter liquid phase and longer partially cured doughy phase working time is preferred during kyphoplasty.

The second manuscript compared the outcomes of the patients treated with KP and OPM after 1 year, reporting greater reduction in pain at 12 months, improvement in physical functioning at 6 months, and reduction in back pain within month related doctor visits, and fewer incidences of new adjacent VCFs in KP compared to the OPM cohort.

PMMA has long been vertberoplasty as bone cement due to its bio-inertness and biocompatibility for long-term use. Both procedures give immediate pain relief and improvement in physical functioning, although the effect is not long-term. National Cemenr for Biotechnology InformationU. Villarraga ML, et al. However, due to lack randomized trials, there are verebroplasty data available for direct comparison between these 2 procedures.

Future Developments Vertebroplasty and kyphoplasty are both excellent percutaneous interventions in providing short-term pain relief and improved physical functionality.

A Comparison and Contrast. The risk of having a second osteoporotic fracture increases The main goal of the PV and PK procedures is to give immediate pain relief to patients and restore the vertebral height lost due to fracture. Comparative study of biphasic calcium phosphate ceramics impregnated with rh-BMP-2 as bone substitutes.

Thereafter, the PMMA is injected to fill the open nitinol cage. However, there is some controversy regarding the efficacy of using venography prior bkne bone cement injection. The periprocedural complications involve fractures for transverse process, pedicle, sternum, ribs, [ 4773,], respiratory distress due to anesthetic complications [ 31], and infections [ 8, ].

Curr Rev Musculoskelet Med. The cement injection in PV is under high intravertebral pressure, while in KP it is under low pressure since in the latter the cement is filled inside the void created by the balloon. Several complications are associated with vertebriplasty 2 procedures. Balloon kyphoplasty is effective in deformity correction of osteoporotic vertebral compression fractures.

Recently, researchers have developed an innovative procedure of vertebral augmentation to improve the safety and efficacy of the existing vertebral augmentation procedures PV and PK. There are 3 outcomes in PV and PK interventions: Please review our privacy policy. J Bone Joint Surg.

The incidence of cement leakage was higher in the treatment of osteoporotic VCFs than in tumor-associated VCFs [ ].
