Brief Summary

Lumbosciatica is a very prevalent pathology. When conservative treatments fail, surgery should be considered. The traditional surgical treatment is lumbar arthrodesis. The vast majority of patients who undergo spinal fusion cannot return to their same job and a good number of them never work again. Another form of treatment for lumbosciatica is the implantation of a lumbar disc prosthesis. This technique preserves the mobility of the lumbar area that has been operated on. This allows for a greater return to work and a higher percentage of those who return to the same job. This study aims to quantify how many of the patients who have had a lumbar disc prosthesis implanted in the last twenty years have returned to their same job, how many have had to change their jobs, and how many have not returned to work and are now totally or completely disabled from work.

Outcome Measures

Primary Outcomes (1)

  • Number of participants who have had a lumbar disc prosthesis implanted in the last twenty years and have returned to their same job

    Percentage of participants who have not returned to work and are now totally or completely disabled from work

    We started to implant total lumbar disc prosthesis in 2006 and have continued up to now. We want to know the results in our patients re work and sport activities at 01 May 2025

Study Arms (1)

Total Lumbar Disc replacement

These patients have been submitted to total lumbar disc replacement and we want to know the work and sportive activities they are able to undertake in the years after the total lumbar disc replacement

Device: We want to know the work and sport activities that our patients are able to undertake after a total lumbar disc replacement

Interventions

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with symptomatic lumbar degenerative disc herniation and/or lumbar disc herniation that underwent a total lumbar disc replacement

You may qualify if:

  • Age over 18 years with symptomatic lumbar degenerative disc herniation and/or lumbar disc herniation.

You may not qualify if:

  • Any patient who BEFORE the implantation of a complete lumbar disc prosthesis had undergone any other type of surgical intervention on the lumbar spine. In particular, patients who had previously undergone a discectomy, whatever its form, or a spinal arthrodesis, whatever its technique, will be excluded from the study.
