The goal of a laminectomy is to relieve pressure on the spinal cord or spinal nerve by widening the spinal canal. This is done by removing or trimming the lamina (roof) of the vertebrae to create more space for the nerves. A surgeon may perform a laminectomy with or without fusing vertebrae or removing part of a disc. Various devices (like screws or rods) may be used to enhance the ability to obtain a solid fusion and support unstable areas of the spine.

It is essentially a “welding” process. The basic idea is to fuse together the painful vertebrae so that they heal into a single, solid bone..

Spinal fusion may relieve symptoms of many back conditions, including:

  • Degenerative disk disease
  • Spondylolisthesis
  • Spinal stenosis
  • Scoliosis
  • Fracture
  • Infection
  • Tumor

The technique of Artificial Disc Replacement has now been internationally approved for clinical practice and we have already performed this surgery on a few patients. The advantage of this procedure is that it returns back the motion in the affected spinal segment and the patient can lead a near normal life without many limitations. The surgery is done from the front and does not involve bone graft harvesting. The disc prosthesis is inserted in-between the vertebral bodies after clearing the degenerative disc disease (DDD).

As the names imply, with a total disc replacement, all or most of the disc tissue is removed and a replacement device is implanted into the space between the vertebras. With a disc nucleus replacement, only the center of the disc (the nucleus) is removed and replaced with an implant. The outer part of the disc (the annulus) is not removed.

Artificial discs are usually made of metal or plastic-like (biopolymer) materials, or a combination of the two. These materials have been used in the body for many years. The most commonly used total disc replacement designs have two plates. One attaches to the vertebrae above the disc being replaced and the other to the vertebrae below. Some devices have a soft, compressible plastic-like piece between these plates. The devices allow motion by smooth, usually curved, surfaces sliding across each other.

Most nucleus replacement devices are made of plastic-like (biopolymer) materials. One such material is called hydrogel. This material expands as it absorbs water. The device is placed into the nuclear cavity of the disc and hydrates to expand and fill the cavity. The device is compressible and by this means, allows motion, much like a normal disc nucleus. Another design consists of a piece of a plastic-like material that coils around to fill the nuclear cavity.

The shoulder joint is a ball-and-socket joint, much like the hip joint. The ball is the top of the arm bone (the humerus), and the socket is within the shoulder blade (scapula).

When shoulder replacement surgery is performed, the ball is removed from the top of the humerus and replaced with a metal implant. This is shaped like a half-moon and attached to a stem inserted down the center of the arm bone. The socket portion of the joint is shaved clean and replaced with a plastic socket that is cemented into the scapula.

The cap moves within the cup. The surfaces that rub against each other (the bearing couple) are made from highly-polished metal. This type of bearing couple is called a metal-on-metal bearing couple.

The cup (acetabular component) is available in two styles: a one-piece cup or a two-piece cup. The one-piece cup is a single component. The two-piece cup has a metal outer shell and a separate metal liner that locks into the shell.

The normal hip joint is a ball and socket joint. The socket is a “cup-shaped” bone of the pelvis called the acetabulum. The ball is the head of the thigh bone (femur). Total hip joint replacement involves surgical removal of the diseased ball and socket and replacing them with a metal ball and stem inserted into the femur bone and an artificial plastic cup socket. The metallic artificial ball and stem are referred to as the “prosthesis.” Upon inserting the prosthesis into the central core of the femur, it is fixed with bony cement called methyl methacrylate. Alternatively, a “cementless” prosthesis is used which has microscopic pores that allow bony ingrowth from the normal femur into the prosthesis stem. This “cementless” hip is felt to have a longer duration and is considered especially for younger patients.

It is performed if the damage is limited to one side of the joint only with the remaining part of the knee joint being relatively spared. It is now possible for the surgeon to replace only that area of the knee joint which is severely damaged.
