Abstract

The anatomy of the intervertebral foramina L1-S1 was studied by the dissection of 106 foramina levels in 13 human anatomic spine specimens. Twenty foramina were examined in each level from L1 to L5 and 26 foramina from L5 to S1. It appears a safe working canal diameter is 8 mm for L1-L4 and 7 mm for L4-S1.
