index, smoking status, the duration of symptoms as well as baseline severity score contribute to perioperative complications. These studies have also indicated that neck pain is more prevalent in patients undergoing laminoplasty compared to that of other surgical techniques, whereas C-5 palsy occurs less in laminoplasty. There is also a slower progression rate of OPLL in laminoplasty compared to laminectomy. Laminoplasty has a progression rate of only 45.4%, while 52.5% is associated with laminectomy. Other miscellaneous complications that were reported include hematoma, progressive kyphosis, and incomplete decompression. The probability of these complications range from 5-20% after this procedure.

Oyama as Z-shaped laminoplasty. The name was given due to the z-shape formed when cutting the laminae. The next method is called, en bloc laminoplasty, and it was a modification of the en bloc laminectomy, which was developed by Tsuji. En bloc laminoplasty decompresses the spine by making the laminae act as a flap, and this flap hovered over the cord without sutures or bone grafts. Later in 1977, Hirabayashi and his colleagues introduced the open-door laminoplasty, which was inspired by the en bloc laminoplasty. This method uses
117:(OPLL), there are two approaches that can expand the spinal canal. These approaches are the anterior approach which is a direct removal of the cord compressing lesion, or a posterior approach which is an indirect decompression of the spinal cord. Laminectomy was one of the main methods for the posterior approach, however, the creation of laminoplasty was able to avoid several problems associated with the laminectomy procedure. Some risks of the laminectomy procedure include postoperative segmental instability,

162:. The spinal cord serves 3 main functions for the body. It provides sensation, autonomic and motor control for all bodily functions and parts. The spinal cord is the most complex yet organized part of the CNS. The entire spinal structure may be divided into 4 sections that create an overall S-shaped curve. These sections include the cervical, thoracic, lumbar, and sacral regions.

At the midline of the vertebral laminae, a drill is used to cut the bone. The lateral sides of the laminae serve as a hinge that allows expansion of the spinal canal. Specifically, the inner cortex of the lateral portion was part of the hinge. An artificial spacer is used to keep the opening fixed.

The laminoplasty procedure was created by
Japanese orthopedic surgeons during the 1970s to 1980s. Over the years, laminoplasty has evolved its technique. The first laminoplasty technique developed was from modifying the Miyazaki and Kirita's technique for laminectomy. This method was described by

The C2 to C7 laminae are drilled at the lateral borders of the laminae. One side of the bone is completely cut, while the other side acts as a hinge. The laminae are then lifted to increase space in the spinal canal. The flap of the laminae is kept open with a suture that is fixed to the

Not only are there many other methods of laminoplasty being created, these new methods falling under the open door or double door laminoplasty category, but also, other techniques are being developed in order to preserve the cervical muscle attachment on the spinous processes.

While the success rate of the laminoplasty procedure is dependent on the underlying condition that causes the need of surgery, the vast majority of patients that undergo this procedure see significant relief of pain and approximately 75% of patients see improvement.
