Oct 30, 2023 · The sacroiliac joint is a synovial-type articulation between the auricular surfaces of the sacrum and ilium. Even though it is classified as a synovial plane joint, the auricular surfaces of the sacroiliac joint show marked irregularities in forms of depressions and elevations.

The sacroiliac joint (SIJ) is a synovial joint between ilium and the sacrum. It has little movement and its main function is to transfer weight between the axial and lower appendicular skeletons.

The distinctive bone structure and complex movement (s) of the sacroiliac joint are held together and powered by an extensive network of ligaments. The muscles surrounding the sacroiliac joint do not specifically move the joint, but the health of these muscles can influence the stability and motion of the joint.

Apr 8, 2023 · The sacroiliac joint is an articulation between the ilium of the pelvis and the sacrum of the vertebral column. It is a strong, weight-bearing joint, which acts to transfer forces from the lower limb to the vertebral column.

This article focuses on the (functional) anatomy and biomechanics of the pelvic girdle and specifically the sacroiliac joints (SIJs). The SIJs are essential for effective load transfer between the spine and legs.

Mar 9, 2025 · The sacroiliac (SI) joint joins the sacrum at the base of the spine to the pelvic ilium by the sacroiliac (SI) joint. It plays a crucial role in transferring weight and force between the upper body and the lower limbs while providing stability and shock absorption. SI joint dysfunction can cause lower back, buttock, or leg pain, which frequently simulates other …

Aug 8, 2023 · The sacroiliac (SI) joint articulates surfaces of the sacrum and the ilium and functions as the transition between the spine and the pelvis. The main roles of the SI joint are to provide stability and offset the load of the trunk to the lower limbs.

The sacroiliac joints (SIJs), the largest axial joints in the body, sit in between the sacrum and pelvic bones on either side. They connect the spine to the pelvis and thus facilitate load transfer from the lumbar spine to the lower extremities.

The sacroiliac joint is an amphiarthrodial joint, formed between the auricular surfaces of the sacrum and the ilium. The articular surface of each bone is covered with a thin plate of cartilage, thicker on the sacrum than on the ilium.

Aug 17, 2023 · Accessory sacroiliac joints are a common finding, present on ~15% (range 13-17.5%) of CT studies, and may be unilateral or bilateral. They are an articulation between the medial aspect of the posterior superior iliac spine and the …
