If the degree of instability is excessive the structural integrity of the spine will be compromised. This decreased stability can produced pain during normal activities, a condition known as mechanical low back pain. The pain is typically confined to the lower back, hips, and thighs. Conservative measures are designed to re-establish stability by strengthening compensatory structures such as the muscles of the lower back and abdominal wall. buy viagra online generic viagra online cheap generic viagra viagra no prescription online classicmotocrossimages.com/mbs-viagra-cheap-pills-ji/ viagra online viagra without a doctor prescription generic viagra online buy cheap viagra howtosmudge.com/pjn-cheap-generic-viagra-online-bn/ If a significant degree of instability exists or conservative measures fail, the structural integrity of the spine is restored through a spinal stabilization surgery. The operative procedure, known as a fusion and fixation, is intended to eliminate the movement across the unstable portion of the spine and reduce the production of pain. Fixation provides immediate spinal stability through the implantation of metallic screws, known as pedicle screws, connected by metallic rods. Long-term stability is achieved through the growth of a bony bridge between the unstable bones, known as a fusion. Surgical procedure the procedure is performed under general anesthesia. A midline incision is made in the lower back overlying the area of instability. Soft tissue is dissected off the back of the spine to expose the unstable spinal segments. A lumbar laminectomy is typically performed to decompress the neural elements, as described in the lumbar laminectomy section. Once the neural elements are free, the spinal stabilization procedure is performed. The bone to create the fusion is harvested from the iliac crest (a part of the hip bone) through the same or separate incision. Using bony landmarks, fluoroscopy or a stereotactic navigational system, the entry site and trajectory of the pedicle screws is identified and the screws are inserted. These adv.
