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.

Yoga as an effective treatment for back pain

New researchs from the U.S. suggests that the millennia-old therapy of yoga could benefit millions of people who suffer from back pain problems. In an article published in the Annals of Internal Medicine on December 20, researchers concluded that yoga act as a more effective treatment for back pain than conventional therapy.
A study conducted at the Group Health Cooperative in Washington State required 101 adults to follow a choice of remedial treatments – a 12-week course in yoga, 12 weeks of standard therapeutic exercise or the same period following instructions in a self-help book. The results showed yoga both expedited relief from pain and had longer lasting benefits. Lead researcher Dr. Karen Sherman said this was because “mind and body effects” were in collusion.

The article states that: “Most treatments for chronic low back pain have modest efficacy at best. Exercise is one of the few proven treatments…however, its effects are often small, and no form has been shown to be clearly better than another. Yoga, which often couples physical exercise with breathing, is a popular alternative form of ‘mind–body’ therapy…[It] may benefit patients with back pain simply because it involves exercise or because of its effects on mental focus. We found no published studies in western biomedical literature that evaluated yoga for chronic low back pain; therefore, we designed a clinical trial to evaluate its effectiveness.” Millions of people worldwide swear by yoga to improve their mental and physical health.

What is the Bone Denisty exam(DEXA scan)?

The bone density test or scan, is designed to check for osteoporosis( a disease that occurs when the bones become thin and weak). Osteoporosis happens when the bones lose calcium and other minerals that keep the bones strong. Osteoporosis begins after menopause in many women, and gets worse after age 65, often resulting in serious fractures. A bone density scan measures the strength of your bones and determines the risk of fracture.

Today, most people will get a bone density scan from a machine using a technology called Dual Energy X-ray Absorptiometry or DEXA for short. This machine takes a picture of the bones in the spine, hip, total body and wrist, and calculates their density. If a DEXA machine is not available, bone density scans can also be done with dual photon absorptiometry (measuring the spine, hip and total body) and quantitative computed tomography scans (measuring the spine). Bone density scanners that use DEXA technology to just measure bone density in the wrist (called pDEXA scans) provide scans at some drugstores. Yet these tests are not as accurate as those that measure density in the total body, spine or hip--where most fractures occur

To take a DEXA bone density scan, the patient lies on a bed underneath the scanner, a curving plastic arm that emits x rays. These low-dose x rays form a fan beam that rotates around the patient. During the test, the scanner moves to capture images of the patient's spine, hip or entire body. A computer then compares the patient's bone strength and risk of fracture to that of other people in the United States at the same age and to young people at peak bone density. Bones reach peak density at age 30 and then start to lose mass. The test takes about 20 minutes to do and is painless.

The DEXA bone scan exposes the patient to only a small amount of radiation--about one-fiftieth that of a chest x ray, or about the amount you get from taking a cross-country airplane flight.
