Minimally Invasive Surgery (MIS) defines a new age of surgical techniques. The goal is to duplicate the success and results of older "open" techniques, but with less exposure and less surgical traum to the patient. As a result, there is much less blood loss, with shorter hospital stays and much faster recovery after surgery. Dr. Perry is an expert in MIS techniques, and is one of a select few spine surgeons in Nevada with this distinction. Dr. Perry has participated as faculty to numerous courses, sharing these techniques with students and fellow spine surgeons around the country.
MIS Procedures Performed:
This surgery removes the disc and/or bone spurs that are putting pressure on nerve roots. This condition is a result of a herniated or degenerated disc. The removed disc is replaced with a small bone graft, or cage device, which will allow the vertebrae to fuse together over time. As the name describes, this procedure is done through the front, or anterior, of the neck. Removing the herniated disc can significantly relieve neck and arm pain. With Dr. Perry's minimally invasive techniques, most patients are able to go home the same day and return to normal function within 2 weeks.
Cervical discectomy is a surgical procedure performed to relieve pressure on the nerve roots in patients suffering from neck and back pain caused by a herniated or ruptured disc in the upper part of the spine. This procedure is most often performed through an anterior approach and involves removing the affected disc and then leaving the space open or filling it with a bone graft and securing it in place with metal screws and plates. Symptoms of pain, numbness and tingling will lessen over time through physical therapy and proper healing.
There are certain conditions that require reconstruction of the front (anterior) of the spine. Classically that has been a complicated procedure due to the organs in the immediate area (Lungs, Heart). As technology has advanced, we have developed less invasive ways to perform the same type of surgery. Like in the lumbar spine, a lateral approach can be utilized to lessen the risk with surgery involving the thoracic spine. This new, minimally invasive technique allows for a much faster recovery as compared to older, more invasive methods.
In certain conditions, the spine is rendered unstable. And if left alone, it may collapse and potentially result in nerve/spinal cord injury. Under those conditions, surgery is done to stabilize the area. This is done using screws and rods to give the necessary support. Bone graft is used to promote the connected bones to grow together as one unit. This type of fusion can be required for trauma, tumors, osteoporosis, or degenerative conditions. It is often combined with a laminectomy.
Lumbar lateral interbody fusion is a surgical procedure commonly performed on patients with degeneration, instability or physical deformities within the lower spine. Interbody fusion involves removing an intervertebral disc from the affected area and replacing it with a bone graft, which will fuse with the surrounding vertebrae over time for restored function, stability and strength.
There are many options available as to how this procedure is performed, including through a posterior, anterior or transforaminal incision. Your doctor will decide which technique is best for you after a thorough evaluation of your condition. Once the incision has been made, the damaged disc is carefully removed and a bone graft harvested from the hip is placed.
Transforaminal lumbar interbody fusion (TLIF) is a surgical procedure performed to remove damaged intervertebral discs and fuse the vertebrae together to relieve painful symptoms within the lower back. This procedure is performed through a single incision in the lower back that cuts the layers of muscle and ligaments on either side of the spine. The damaged disc is then removed with a special instrument, and the empty space is filled with a bone graft to maintain the structure of the spine. The TLIF procedure is similar to a posterior lumbar interbody fusion (PLIF), except that the discs are removed from the side during TLIF, rather than the back.
Lumbar posterior fusion is performed to join (fuse) together the vertebrae in the lumbar spine in patients with conditions such as spinal stenosis, degenerative disc disease or spondylolisthesis. Lumbar spine fusion surgery is performed through an incision in the front of the body. During the procedure, the disc between the affected vertebrae is removed, and a bone graft is inserted into the empty space. Movement of the spine in the treated area will not be possible after surgery, so it is usually only performed in one area. Patients will require physical therapy and other assistance after surgery in order to restore proper function.
A microdiscectomy is performed to relieve pressure on nerve roots caused by a herniated disc. A microscope is inserted through a tiny incision in the lower back to view the pinched nerve and then remove the portion of the disc that is applying pressure on it.
A lumbar laminectomy also relieves the pressure of a pinched nerve, but does so by removing a portion of the lamina, the bony rim around the spinal canal. This procedure is often used to treat spinal stenosis and disc degeneration. An X-ray is often used to ensure accuracy of this procedure.
Vertebroplasty is a minimally invasive procedure used to treat vertebral compression fractures (VCF), which are fractures of the vertebra. These fractures commonly occur as a result of osteoporosis, spinal tumors or injury, and can cause severe pain and limited mobility. They can also lead to abnormal spine curvature and increase a patient's risk for serious spinal complications.
In many cases, vertebral fractures can be treated through conservative methods such as bed rest, a back brace or pain medication. Like fractures in other areas of the body, these fractures can heal on their own. However, patients with osteoporosis or whose fractures have caused severe, long-term pain may benefit from a minimally invasive procedure such as vertebroplasty to relieve symptoms. This procedure is also recommended for patients who are too weak to undergo spinal surgery, or have a malignant tumor within the spine that has caused vertebral damage. Vertebroplasty is most effective when performed on fractures that are less than six months old.
Kyphoplasty is a minimally invasive procedure used to correct vertebral compression fractures within the spine. Compression fractures may develop as a result of osteoporosis, spinal tumors or a traumatic injury, and may be treated with rest, pain medication and braces for mild fractures. Kyphoplasty is most effective for patients with osteoporosis or metastatic tumors, and is usually performed after traditional treatments have been unsuccessful for four to six weeks. During the procedure, a device called a balloon tamp is inserted into the affected area and inflated to relieve compression and restore the vertebra to its normal height. The area is then filled with an injected bone cement in order to keep the bone in place and prevent compression from occurring again. Most patients report a significant reduction in pain after the kyphoplasty procedure.
