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).
Zone I fractures occur at the wing-like structures of the sacrum (sacral ala) lateral to the neural foramina; this type of fracture can cause lumbar L5 nerve root impingement. Approximately 6% of individuals with Zone I fractures experience neurological injuries (Wheeless).reatment. Stability of the sacral fractures determines the course of treatment. Most sacral fractures are stable, and bed rest is the prescribed treatment along with a sacral corset or brace for comfort while the fracture heals.
