Session 7 - Pelvic Girdle Flashcards
What does the pelvic girdle consist of?
The two hip bones and the sacrum
What are the three main functions of the pelvic girdle?
to transfer forces from the axial skeleton to the lower limb provide attachment for muscles protect the pelvic area
Where do the hip bones articular with each other anteriorly and posteriorly?
Hip bones articulate with each other anteriorly at the pubic symphysis Articulate with the sacrum posteriorly
What is the hip bone formed from?
The fusion of three bones - The illium - The ischium - The Pubis
Up to the age of 18,how are the hip bones connected?
Triradiate cartilage in the acetabulum
What is the acetabulum?
A concave surface formed from the joining of the ilium, the ischium and pubis. Articulates with the pubis.
What is A?
A is the Ilium
What is B?
The acetabulum
What is C?
The ischium
What is D?
The pubis
What is A?
Illiac crest
What is the use of the iliac crest?
Many of the muscles and fascia of the abdomen attach here
What is B?
The illiac fossa
What is J?
The Gluteal surface of the illium, to which the gluteal muscles attach
What is the ischium composed of?
The body and the ramus (another name for a division)
What is O and what does it form part of?
The body of the ischium, forms part of acetabulum
What is N?
The ischial ramus
What is E?
The ischial tuberosity
What is the pubis composed of?
A body and two rami (divisions)
What is F?
The pubic symphysis, point of articulation of the two pubi
What is L?
Body of the pubis
What are K and M?
K - the superior ramus of pubis M - the inferior ramus of the pubis
What are I and G?
I - the superior ramus of the pubis G - the inferior ramus of pubis
What is H?
Body of ischium
What forms the “ring” of the pelvic girdle?
The pubic ami, the acetabulum, the ischium, the illium and the sacrum.
What does the ring formation of the pelvic girdle mean?
Fractures occur together - very difficult to break one side without breaking or dislocation the othe
What is the most common way to break pelvis??
Direct trauma, or by falls of feat - force is transmitted to pelvis from lower limb
Where do fractures occur in the pelvis?
Weaker points, such as the superior and inferior pubic rami, the acetabulum of in the region of the sacroiliac joint
What is a common complication of pelvic fractures?
Soft tissue injury - bladder and urethra are relatively close and can be damaged
What is the sacroilliac joint?
This
