![]() ![]() ![]() Most spinous process fractures do not cause spinal cord damage. When a vertebra is damaged, the spinal cord may also be damaged. Muscles and ligaments in your back are attached to this part of the vertebra. It's stretched in flexion, it`s fibers resist separation of spinous processes during forward flexion, during hyperflexion interspinous ligament and supraspinous ligament are the first to fail. A spinous process fracture is a break or crack in the back part of a vertebra.The supraspinous ligament helps maintain the upright position of the head.The supraspinous ligament serves as a midline attachment for some important muscles.Limits flexion along with other ligaments of vetebral column.Between the spinous processes it is continuous with the interspinal ligaments.The middle fibers of the supraspinous ligament blend with the dorsal layer of the thoracolumbar fascia. \The deep layer of the supraspinous ligament is reinforced by tendinous fibers of the multifidus muscle. The most superficial fibers of this ligament extend over three or four vertebræ those more deeply seated pass between two or three vertebræ while the deepest connect the spinous processes of neighboring vertebrae. It is thicker and broader in the lumbar than in the thoracic region, it merges to thoracolumbar fascia. 10, 11 Therefore, it is essential that the accuracy of palpation protocols be tested and compared with other tests, such as radiographic analysis. The ligament is almost always absent at L5/S1. Health care professionals should use palpation protocols that enable the correct identification of spinous processes with minimal errors. The supraspinous ligament is well developed only in the upper lumbar region and may terminate at 元, although the most common termination site appears to be at L4.
