What is AIIS of hip?
What is AIIS of hip?
The anterior inferior iliac spine (AIIS) apophysis is a bony prominence, from which the direct head of the rectus femoris and the ilio-capsularis muscles originate and is situated superior and antero-medial to the most lateral point on the acetabular rim.
What is Subspine decompression hip?
Subspine decompression is the treatment he uses to restore the range of motion of the hip, while decreasing inflammation and hip pain. Subspine decompression is done arthroscopically, using a small camera (called an arthroscope) and specialized instruments, used to operate within the hip joint.
What is AIIS?
The anterior inferior iliac spine (AIIS) is bony prominence on the anterior border of the ilium forming the superior border of the acetabulum. Attachments include the Iliacus, origin of straight head of the rectus femoris, and also the proximal ileofemoral ligament (Y-ligament or ligament of Bigelow).
What is AIIS decompression?
Low AIIS decompression is a safe, effective, and reproducible procedure for addressing subspinal impingement. Creating a flat anterior acetabular surface between the most anteroinferior prominent point of the AIIS and the acetabular rim allows flexion and internal rotation of the hip joint without impingement.
What connects to AIIS?
Below the notch of insertion of sartorius on anterior border of the ala of ilium, is the anterior inferior iliac spine, which ends in the upper lip of the acetabulum; it gives attachment to the straight tendon of the Rectus femoris and to the iliofemoral ligament of the hip-joint.
What is a Subspine impingement?
Subspine impingement (SSI) is an extra-articular impingement condition that can contribute to hip pain without or in conjunction with femoroacetabular impingement (FAI). It results from abnormal contact between the anterior inferior iliac spine (AIIS) and proximal femur (1).
Which muscles attach to AIIS?
The Anterior Inferior Iliac Spine (AIIS) is a piece of bone just above the hip joint, which is the attachment of part of the rectus femoris muscle, one of the quadriceps muscles of the front of the thigh.
How do you palpate the AIIS?
For AIIS, palpate just below and medial to the ASIS. This is the attachment site for the rectus femoris, and again, tenderness here may suggest tendonitis or avulsion. From there move onto the greater trochanter.
Can hip impingement heal without surgery?
Non-surgical treatment should always be considered first when treating impingement. This condition can often be resolved with rest, modifying activity behaviour to adapt to change in hip structure, physical therapy input and/or appropriate painkillers.
