Overview - upper and lower limb Flashcards
Femoral head fits into?
Acetabulum
Anatomical neck of the femur is?
Just inferior to the femoral head
Surgical neck of the femur is?
Region of the femoral neck that breaks the most
Relation of anatomical and surgical neck in the femur?
In the femur, these are the same
Muscles attach where on the femur?
Greater and lesser trochanter
Shenton’s line is?
Line from superior pubic rami to medial border of femoral neck
Change to Shenton’s line indicates?
Damage to the neck of the femur e.g. fracture
Three ligaments of the hip joint? Anterior or posterior?
Iliofemoral - anterior
Pubofemoral - anterior
Ischiofemoral - posterior
Strongest ligament of the hip joint?
Anterior iliofemoral ligament
Hip joint is stable or not very stable?
Very very stable
Appearance of the iliofemoral ligamnet?
Y-shaped ligament
Most common dislocation at the hip and why?
Posterior dislocation - the iliofemoral is strongest ligament and this is anterior
Change in shape of the ligaments to the hip joint upon movement of the leg is?
Relaxed when the hip is flexed
When leg moves backwards and extends, ligaments twist and turn
When is the femoral head inserted deeper into the acetabulum?
When the ligaments of the hip twist upon leg extension
Ligamentum teres is where?
Inside the acetabulum
Ligamentum teres function is?
Helps to strengthen the joining of the head of the femur into the acetabulum
What runs within the ligamentum teres?
Artery
Main blood supply to the hip joint is?
Circumflex arteries - medial and lateral
Circumflex arteries originate from?
Femoral artery
Artery to the head of the femur provides blood supply to the hip in whom?
Children
Artery to the head of the femur originates from?
Obturator artery
Necrosis of head of the femur can be caused by?
Fracture to the neck of the femur
When does the external iliac artery become the femoral artery?
When it passes under the inguinal ligament
What branch does the external iliac artery give off?
Inferior epigastric artery
