Hip Joint Flashcards
What type of joint is the coxofemoral joint?
Diarthrodial
what is the coxofemoral joint composed of? (2)
-Acetabulum
- Femoral head.
What can the acetabulum be divided into? (2)
Lunate surface
Acetabular fossa.
Where does the ligament of the head of the femur originate?
Fossa
Normal femoral head/neck are:
A) Inclined by what angle to the femoral long anxis?
B) Anteverted by what angle?
A) 130-145
B) 12-40
Define anteverted.
Inclined forwards
Are gluteal muscles primary or secondary stabilizers of the hip joint?
2ry
Are adductor muscles primary or secondary stabilizers of the hip joint?
2ry
Are abductor muscles primary or secondary stabilizers of the hip joint?
2ry
Is the ligament of the head of the femur primary or secondary stabilizers of the hip joint?
1ry
Is the joint capsule a primary or secondary stabilizers of the hip joint?
1ry
Is the acetabular labrum a primary or secondary stabilizers of the hip joint?
2ry
Where does the blood supply to the femoral head come from? (2)
Intraosseous supply from the metaphysis
Epiphyseal system
What does the femoral head blood supply cross from the metaphysis?
Physeal scar
The blood supply to the femoral head and neck comes from the intraosseous supply from the metaphysis, which crosses the physeal scar into the femoral head in what age animals?
Mature animals
The epiphyseal system which enters the femoral head through the joint capsule via?
Cranial and caudal circumflex femoral arteries.
When retracting the biceps femoris - what lies underneath which needs extra care?
Sciatic nerve
On the craniodorsal approach to the hip:
A triangle can be identified bounded by what:
A) Dorsally (2)
B) Laterally
C) Medially
A) Middle and deep gluteal muscles
B) Vastrus lateralis muscle
C) Rectus fem
What is the normal range of inclination of the femoral neck of the dog?
135 – 145 degrees
craniodorsal approach to the hip:
Where is the skin incision
A skin incision is centred on the greater trochanter extending distally to one third of the length of the femur. Proximally the incision curves slightly cranially and extends approximately halfway between the greater trochanter and the dorsal midline.
craniodorsal approach to the hip:
The superficial leaf of the fascia lata is incised where?
Along the cranial border of the biceps femoris muscle.
craniodorsal approach to the hip:
The biceps femoris muscle is retracted A) and the deep leaf of the fascia lata is incised to free the insertion of the B)
A) caudally
B) the tensor fasciae latae muscle
craniodorsal approach to the hip:
The incision continues proximally through the intermuscular septum between the ? border of the superficial gluteal muscle and the tensor fasciae latae muscle.
cranial
craniodorsal approach to the hip:
What are retracted cranially (2) and the biceps caudally. Blunt dissection and separation along the neck of the femur allows visualization of a triangle bounded
Fasia lata
And attach tensor fasciae latae
