What is the sacral alar?
The ala of sacrum is the upper part of the lateral part of sacrum, lateral to the first sacral vertebra. It is a large triangular surface, which supports the Psoas major and the lumbosacral trunk, and in the articulated pelvis is continuous with the iliac fossa.
What is the sacral region area?
The sacral region (sacrum) is at the bottom of the spine and lies between the fifth segment of the lumbar spine (L5) and the coccyx (tailbone). The sacrum is a triangular-shaped bone and consists of five segments (S1-S5) that are fused together.
What structure is in the sacral region?
The sacral vertebrae—also called the sacral spine—consists of five sacral vertebrae bones. These bones fuse together to form the sacrum, the shield-shaped bony structure located at the base of the lumbar vertebrae (the five cylindrical bones forming the spine of the lower bank) and connected to the pelvis.
What is the function of sacrum ala?
On either side of the lumbosacral joint are winglike structures (sacral ala) which connect to the iliac bones and form the top of the sacroiliac (SI) joint. Attached to either side of the sacrum are the iliac bones. These wings of the pelvis provide stability and strength for walking and standing.
What does the sacrum do?
The sacrum is a shield-shaped bony structure that is located at the base of the lumbar vertebrae and that is connected to the pelvis. The sacrum forms the posterior pelvic wall and strengthens and stabilizes the pelvis.
How serious is a sacral fracture?
Although uncommon, sacral stress fractures are an important and curable cause of low-back pain. They should be suspected in elderly patients suffering from low-back or pelvic pain without a history of trauma.
How do you treat a sacral fracture?
Sacral fractures can be treated non-operatively or surgically. Non-operative treatment is based on rest, pain relief therapy and early mobilization as tolerated. Surgical techniques can be split into two main groups: posterior pelvic fixation techniques and lumbopelvic fixation techniques.

What is the shape of the ALA of sacrum?
Ala of Sacrum / 3D image and Description. Ala of sacrum is a large triangular surface either side of sacral base, continuous with iliac fossa (akin to adapted and joined transverse and costal processes elsewhere spine). Tagged under: muscle.
Where is the probe in the sacral ala?
The probe was placed in the sagittal plane across the caudal border of the transverse process of L5 and the cranial border of the sacral ala, visualizing the interspace (osteofibrotic tunnel) in-between the bony structures on both images.
What causes SIFS on the left medial sacral ala?
The left medial sacral ala shows adjacent contrast enhancement with a low intensity central necrosis. SIFs often arise insidiously, resulting from axial stresses transmitted from the spine to a sacral ala with deficient elastic resistance.
