Artificial lumbar disc prosthesis

Intervertebral disc endoprostheses – a movement and function-preserving surgical method for the spine

The implantation of a disc prosthesis (artificial replacement) is a globally accepted method for the treatment of symptomatic degenerative disease of the intervertebral discs. A minimum of 6 months of conservative therapy should be tried beforehand. If this fails, or if any uncontrollable pain or nerve disorders arise, health insurance firms in Switzerland cover the costs of the operation providing that no more than two discs are affected and there is no primary osteoarthritis of the facet joints.a6459e8ad5 The operation is performed under a general anesthetic administered through the abdominal wall. Depending on the nature and height of the diseased intervertebral disc, the approach to the spine is either through a lower abdominal cross-sectional incision or a longitudinal incision in the skin of about 4-6 cm. As a rule, the peritoneum remains intact, so that disruptions to the intestines can be avoided. Once the large vessels and nerves – the abdominal aorta and vena cava large – located to the front of the spine have been carefully pushed aside, the affected intervertebral disc is exposed. The anterior longitudinal ligament and the intervertebral disc ring can be opened and the defective disc removed completely. LP-ESP The viscoelastic disc prosthesis (VTDR) Freedom ™ Lumbar Disc (FLD) for the lumbar spine or Freedom Cervical Disc (FCD) for the cervical spine is a novel viscoelastic disc prosthesis to replace a worn disc. The unique design of the latest generation of this prosthesis has the following advantages: – restoration of normal mobility and strength of the affected segment of movement. – Realistic 3D imitation of the human intervertebral disc. – Normal shock absorbing effect like that of the natural intervertebral disc. – Full load capacity on the spine. – Restoring of the natural function of spinal joints, muscles, ligaments and tendons.

What happens after surgery?

After surgery you will stay in hospital for a few days . In general, these are about 3-4 days after an operation on the cervical spine and about 6-7 days after an operation on the lumbar spine. Because the prosthesis is usually instantly motion- and pressure-resistant, you can get up one day after the procedure. In contrast to fusion surgery you are able to sit at this point, but should avoid bending forward under loads, overstretching, lifting heavy objects and abrupt twisting of the spine. However, “natural” movements are allowed.  Special treatment (physiotherapy, mobilization, muscle building etc) then follows the operation. As a rule, the prosthesis has grown into the bone after about 3 months. This is checked by x-ray. Obligatory follow-up checks are carried out regularly and the findings are documented in the SWISS spine register, which guarantees the maximum safety and after-care in this operation method.
