Brief summary

Degenerative lumbar pathologies are characterised by functional impairment and the occurrence of severe chronic pain and disability Arthrodesis of the lumbar spine is a common surgery for the treatment of degenerative lumbar pathologies. It is commonly performed during a hospital stay that can vary from 3 to 7 days. The development of mini-invasive techniques and the development of the Improved Rehabilitation after Surgery programmes, has considerably reduced the hospital stay of the patients. It is possible that in the future mini-invasive lumbar arthrodesis will be performed on an ambulatory as a standard procedure, but its safety, efficacy and patient satisfaction must be proven and validated.

Detailed description

Degenerative lumbar disease (DLD) is a condition of increasing frequency, affecting millions of patients worldwide. They are characterised by functional impairment and the occurrence of severe chronic pain and disability. Arthrodesis of the lumbar spine is a common surgery for the treatment of DLD. It is commonly performed during a hospital stay that can vary from 3 to 7 days. The advent of mini-invasive techniques and the development of Improved Rehabilitation after Surgery program has made it possible to considerably reduce the duration of hospitalization of patients with a high rate of satisfaction, a reduction in costs and without increasing morbidity. In spinal surgery, decompression procedures such as discectomy and lumbar recalibration are frequently performed on an ambulatory. The first American studies with a low level of evidence on the management of mini-invasive lumbar arthrodesis are beginning to appear. It is quite possible that in the future this type of procedure will be carried out on an ambulatory as a standard procedure, but its safety, efficacy and patient satisfaction must be proven and validated. In the United States, 23-hour hospitalizations are considered as ambulatory procedures, whereas in France, ambulatory is qualified as such when the patient is admitted and discharged in the same day. The study population was patients who had failed medical treatment (analgesics and rehabilitation) for more than three months and who required a mono-segmental arthrodesis procedure for the management of their lumbar-radiculalgia.

Interventions

PROCEDUREmini-invasive lumbar arthrodesis

* The mini-invasive posterior approach is performed using a trans-muscular Wiltse approach. Pedicle screws, neurological decompression and intersomatic cage placement are performed. * The mini-invasive anterior approach is performed via a left retroperitoneal pararectal approach. After complete discectomy, an intersomatic cage stabilised by a screwed plate will be placed.
