To fill this knowledge gap, Dr. Lukens and colleagues looked at the diagnostic yield and complication rates in 62 patients with surgically altered bowel anatomy who underwent DBE at Mayo Clinic in Florida between 2006 and 2011: 1  Eleven of the procedures were DBE-ERCPs.
The lateral masses are paired blocks of bone located lateral to the sacral foramina. The sacral ala is the wing-shaped bone found lateral to the S1 vertebral body. Histologic study of the sacral alae demonstrates decreased trabecular density (âalar voidsâ) within each of these structures (3).
The lower part of the vertabrae above the coccyx is the sacrum, and it is one bone that is made of 5 forged bones, causing an irregular flat bone. This causes the dimples. A sacral dimple is an indentation in the skin on the lower back that is present at the time of birth.The dimple is usually small, shallow and can be found above the buttocks. Researchers do not know what causes sacral dimples, but generally they are harmless and do not need any medical treatment.However, a sacral dimple can reveal a more serious abnormality involving the spine and/or spinal cord, such as spina bifida.lso known as Dimples of Venus. We all have dimples on our lower back/ above our butt because of our skeletal and muscular structure, not our genes.
