PLAINSBORO, N.J., May 5, 2009 (GlobeNewswire via COMTEX News Network) — Integra LifeSciences Holdings Corporation (Nasdaq:IART) announced today the launch the Coral(TM) Extended Tab Spinal Screw series, a range of polyaxial pedicle screws designed to be used with the Coral(TM) Spinal System. The Coral(TM) Extended Tab Spinal Screw series will be available in solid, fenestrated and cannulated styles, and they provide an exciting addition to the Coral Spinal System currently marketed in the United States.
Coral(TM) Extended Tab Spinal Screws are designed for applications where the extent of the vertebral misalignment would not allow a standard sized tab pedicle screw to properly engage with the rod component of the system without using additional instrumentation. Extending the tabs makes this new series of pedicle screw particularly useful for the correction of spinal deformities, such as spondylolisthesis and scoliosis.
Spondylolisthesis refers to the misalignment of one or more vertebrae in relation to each other and may be present at birth or develop over time. Spondylolisthesis is more common among athletes who participate in sports that involve repetitive spinal hyperextension, such as diving, weight lifting, wrestling and gymnastics. In procedures to correct spinal spondylolisthesis, one or more Coral(TM) Extended Tab Spinal Screws may be placed in the slipped vertebra, using the extended tabs to pull the vertebra into proper alignment.
Scoliosis is predominantly a lateral deformity of the spine, often combined with rotational misalignment of the vertebrae. Three to five in every 1,000 children develop spinal scoliosis considered severe enough to require surgical intervention. For scoliosis correction procedures due to the spinal curve, it may be challenging for a surgeon to seat the rod properly into the screw head. The Extended Tab Screw enables a surgeon to seat the rod into the screw head, commonly referred to as “reducing the rod,” without using additional rod persuasion instrumentation.
