Need info on lumbar disc replacement

orthotech student, we try to encourage members to do their own research. Have you tried GOOGLE? I looked at lumbar disc replacement and came up with over 89,000 hits. Do this and I am certain you will be able to collect sufficient information to make a good presentation.

orthotech student: perhaps we misunderstood each other. There are multiple sites with explanations on the procedures. Are you speaking of scrubbing in and doing the actual surgery? I doubt you will find that in a general site. Look at the research on medscape.com. It has outcome criteria, history etc.

You do need to register but it's free and has a good means of keeping track of your CEs.

There is much that can be found on the procedure, you may wish to look up Lumbar Spine Surgery, or the specific procedure if there is one that you need to report on.

You can find articles that will give you step by step instructions to performing it. But you need to go to a site that will be geared towards health care practitioners and not the lay public.

WebMD also has much on this topic.
Also your school library should have books on this specific topic as well as have subscriptions to Jounals that you may look up procedures in as well.

Best of luck to you.
