ABSTRACT
Objective To explore the puncture technic and method of the transabdominal L5/S1 lumbar diskectomy (TALD). Methods Two cases of cadaver were dissected and L5/S1 intervertebral disks were explored and punctured from different angles in order to probe the proper puncture angle for the needling. The radiographs of the lumbar and sacral vertabral samples of 30 cases were scrutinized and analysed to find the pancture imaging marks of the bones. When performing barium meal examinations, the lumbar and sacral spine of 200 cases were inspected to figure out the opacification of the rate imaging marks. 68 cases TALD were reviewed. Results The most pivotal process of the TALD is the needle puncture should be in parallel direction with lumbosacral interspace and then be pushed into the intervertebral disk. In order to make sure of the puncture point two sticking points should be fixed, on the abdomen and the another at the front edges of L5/S1 intervertebral disks. The five imaging makes of the lumbar, sacral, spine together with the neighboring L5/S1 intervertebral disks are of important help to find the front edges. Conclusion The correct puncture method is very important for performing TALD.
