What is cause of a prolapsed intervertebral disc?

Nornal Aging. Disc prolapse, bulging, and herniation are part of normal aging and having one doesn't mean you you will have pain or disability. About 50% of asymptomatic individuals (without history of low back pain) aged 20-39 have bulging discs and about 21% have ruptured discs in their lumbar spine (low back).

Hello, is there any long term complication for lumbar (l5 s1) discectomy and laminectomy for prolapsed intervertebral disc. Thank you?

Second surgery. It is always possible to need an additional diskectomy if the disk re-herniated. It is also possible that you may require a fusion in the future is that segment becomes unstable. Don't think of your diskectomy as a cure. Remember that unhealthy disks herniate- healthy ones don't unless there's an injury. Diskectomy is very effective and i hope yours lasts a long time.

This is assuming you are a non smoker a smoking has a negative impact on outcome as does obesity. Read more...
