What is the most common avulsion fracture in the pelvic area?
The most commonly reported sites of avulsion fracture in the pelvis are the ASIS, AIIS and IT.
What is anterior superior iliac spine avulsion fracture?
DESCRIPTION. Avulsion fractures of the anterior superior iliac spine (ASIS) are separations of bone resulting from pulls of muscle–tendon units. These may occur in fully grown athletes, although in the pelvis, they tend to occur more commonly in skeletally immature (growing) athletes.
What attaches to the anterior inferior iliac spine?
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).
How long does it take for a pelvic avulsion fracture to heal?
How is a pelvic avulsion fracture treated? Pelvic avulsion fractures require a long period of rest and changes in activity in order to heal. Typically, these injuries will get better with four to six weeks of rest.
What happens if avulsion fracture doesn’t heal?
When a bone fracture is untreated, it can result in either a nonunion or a delayed union. In the former case, the bone doesn’t heal at all, which means that it will remain broken. As a result, swelling, tenderness, and pain will continue to worsen over time.
What is an avulsion in medical terms?
Avulsion: Tearing away. A nerve can be avulsed by an injury, as can part of a bone.
What is an avulsion fracture?
An avulsion fracture occurs when a small chunk of bone attached to a tendon or ligament gets pulled away from the main part of the bone. The hip, elbow and ankle are the most common locations for avulsion fractures in the young athlete.
What muscles attach Asis?
The anterior superior iliac spine refers to the anterior extremity of the iliac crest of the pelvis. This is a key surface landmark, and easily palpated. It provides attachment for the inguinal ligament, the sartorius muscle, and the tensor fasciae latae muscle.
What muscle attaches to the anterior superior iliac spine?
sartorius muscle
The anterior superior iliac spine (abbreviated: ASIS) is a bony projection of the iliac bone and an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis, which provides attachment for the inguinal ligament, and the sartorius muscle.
What is the function of the anterior superior iliac spine?
The anterior superior iliac spine (abbreviated: ASIS) is a bony projection of the iliac bone and an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis, which provides attachment for the inguinal ligament, and the sartorius muscle.
Which muscle attaches to the anterior inferior iliac spine?
Posteriorly is the posterior superior iliac spine and the posterior inferior iliac spine. The rectus femoris muscle of the quadriceps group of thigh muscles attaches to the anterior inferior iliac spine, as well as the iliofemoral ligament.
What is anterior inferior iliac spine?
[edit on Wikidata] The anterior inferior iliac spine (abbreviated: AIIS) is a bony eminence on the anterior border of the hip bone, or, more precisely, the wing of the ilium (i.e. the upper lateral parts of the pelvis).
