The balloon was increased sequentially up to about 600 mm of pressure with partial fill.On the right just at the very beginning of inflation of the balloon, the balloon broke with minimal pressure.There was leakage of dye in the vertebral body and then exiting posteriorly.The cement was then inserted, first on the right and this was for a total of 6 ml.The cement was seen to be starting to creep posteriorly.The needle biopsy core was placed into the needle biopsy sheath.The cement was then introduced on the left side.On the left side, cement was sequentially filled into the vertebral body.During the process of filling, the cement was seen to extrude out into the canal.Cement fill was stopped.It was difficult to determine if the cement extrusion was either on the right or the left side due to the dense anterior fill and therefore, the o-arm was brought into the room.This verified placement of the cement on the right side.Procedure became bilateral t12-l1 laminotomy with partial facetectomy without discectomy and without foraminotomy- durotomy repair on the right at l1.
