A common cause of low back and leg pain is a bulging or herniated disc in the lumbar area. Symptoms may include dull or sharp pain, leg weakness or tingling, or sciatica?pain that shoots down your leg. Illustrations show a normal and herniated disc.
Most patients with a lumbar herniated disc will not require spine surgery. In 4 to 6 weeks, most patients find their symptoms are relieved using non-surgical treatments.
Recent advances in several different fields are significantly impacting anterior cervical spine fixation. Material engineering has developed several types of new materials to replace traditionally used bone products and titanium.
The most commonly available polymer is polyetheretherketone (PEEK). The PEEK graft replacements are stronger than bone but they are softer and less likely to cause the adjacent bone to collapse.
Medtronic Sofamor Danek has introduced the first product using bioengineered bone morphogenetic protein (BMP). In some uses, fusion rates have been near 100%.
