29-3-11 50M DH L4-5, Free disk fragment.

A 50 year- old male, 2M of LBP and L5, S1 left leg pain. His cafl is atroply, (35/31).,LATR 2/4. SLT 40. MRI show DH L4-5 with free disk fregment move down at the L5-S1 level. I did fenestration at L4-5 first, after taking out the L4-5 free disk fragment ,Left L5 nerve have swelled, so it have been narrow. I have been not sure that there was more free disk below susch as on MRI, so I did hemilaminectomy, athough I didnt see any thing more ,it make the L5 nerve more comfortable. Infact, the last axial picture show that the left nerv was swelled. we dont to do hemilaminectomy, I am sorry about it.
