Hi,
I am Dr.Bruno. I have read your question with care and understand your concerns. Let me try to help you
MRI Report : transitional anatomy with bilateral pseudoarticulation at old be labeled l5/s1. There is a grade 1
retrolisthesis of l4/l5.
Meaning : This means that there are few problems with the various Connections (joints) between L4
Vertebral Bone, L5 Vertebral Bone and S1 Vertebral Bone
There is also a Subluxation / Displacement / Slipping of L4 Bone over L5 Bone
Now
If this "slipping of bone" does not cause any problem, you can try simple treatments
But
If some nerves are getting compressed because of this "slipping of bone" and if you have pain /
numbness / weakness, you may need surgery
Hope you found the answer helpful.
If you need any clarification / have doubts / have additional questions / have follow up questions, then please do not hesitate in asking again. I will be happy to answer your questions.
Let me know if I can assist you further.
Take care.
