title: [Twelve cases of total arthroplasty of lumbar disc. Preliminary results at 6 months].
abstract: Lumbar pathology is a problem with growing incidence in developed countries. Lumbar pain caused by disc degeneration is the most frequently cause of functional restriction in patients under 45 years old. Discectomy, laminectomy and posterior spinal fusion have been the traditional surgery treatment. Many patients continue with pain as a consequence of mechanical damage at the functional unit, with different degrees of instability and adjacent disc damage. There are two types of strategies for disc replacement: disc nucleus arthroplasty and total disc arthroplasty. A clinical essay was made in Angeles Mocel Hospital during the period between October 2003 to March 2005. Eight patients with degenerative lumbar disc disease or contained disc herniation, were treated with 12 disc prosthesis, previously they showed no improvement with conservative treatment at minimum 4 months. Preoperative and postoperative pain was reported with the analogue visual score and the Oswestry score. Eighty percent presented immediate postoperative improvement and 100% after 6 months using Oswestry score. This procedure offers good outcome at short term, when its well indicated. This treatment requires a multidisciplinary team and elevates the costs. We need long term follow up results.
