Abstract
Sacrum is a large triangular bone, forming postero-superior wall of the pelvic cavity.
During the routine study of bones in the department of Anatomy, an unusual variation
in the sacrum was noted. The bone showed high sacral hiatus i.e., at the level of
3rd sacral vertebrae and non-fusion of lamina of 1st sacral vertebrae This type of
anomaly is very rare, which prompted us to report the case. The knowledge about this
rare variation is important for orthopaedicians and anesthetists since the high sacral
hiatus may lead to clinical procedural failures. It is also important for accurate
diagnosis of patients with low back pain. Non-fusion of lamina of 1st sacral vertebrae
may be associated with spina bifida occulta and may lead to painful condition of back.
