Vertebroplasty with Procedure Demonstration

What is Vertebroplasty :
The vertebral column or backbone tends to get weak as a person gets old. This is more common in women since female hormones are necessary for normal mineralization. The weak bones in the spine collapse, producing painful fractures. Till a few years ago the only treatment that was available for condition was a major surgery. However thanks to interventional radiology today a fractured bone of the spine can be strengthened by injecting a specialized medical cement ( bone cement) into the diseased vertebral body .

Procedure Demonstration :
Stryker Vertebroplasty uses a specially formulated acrylic bone cement to stabilize and strengthen the fracture and vertebral body. Its done on an outpatient basis and requires only a local anesthetic and mild sedation, eliminating the complications that may result from open surgery and general anesthesia. Stryker Vertebroplasty is considered a minimally invasive procedure because it is done through a small puncture in the patients skin (as opposed to an open incision). Technically simple, it usually takes about 30 minutes to complete.

Using sterile technique and fluoroscopic visualization, a 10-, 11- or 13- gauge needle is advanced into the fractured vertebra using a transpedicular approach. Bi-pedicular needle placement is recommended. Once the needles are in the correct position, bone cement is slowly injected into the vertebral body, diffusing throughout the intertrabecular marrow space and creating an internal cast that stabilizes the bone.

Following the procedure, patients lie flat on their back for a short period of time as the cement continues to harden. They may then go home. Almost all patients undergoing Stryker Vertebroplasty experience 90% or better reduction in pain within 24-48 hours and increased ability to perform daily activities shortly thereafter.
