Hip Anatomy Flashcards
(18 cards)
What is the main hip joint
Acatabulofemoral Joint
What are the main movements involved in the hip joint
Flexion, extension, abduction, adduction, medial/lateral rotation
Name the principle bones in hip joint
Illium, ischium, pubis, femur (head, neck and greater/lesser trochanters)
Name the capsular ligaments in the hip
Illiofemorral, pubofemoral and ischiofemoral
Name the intra-capsular ligaments in the hip
Transverse acetabular and ligamentum teres
What muscles are there in the hip muscles
Gluteal, hip flexors ITB, piriformis, adductors, quadratus femoris, obturator internus and externus and hamstrings
What are the functions of the gluteal muscles
Important for extension, abduction and stabillity
What are the functions of the hip flexors
Flexion and stabilise the hip joint
Flexion of hip: maximum degree and limited by
90-115 degrees and limited by hamstrings and trunk
Extension of hip: maximum degree and limited by
15-30 degrees and limited by iliofemoral and pubofemoral ligaments
Abduction of hip: maximum degree and limited by
50-60 degrees and limited by pubofemoral ligament and greater trochanter
Adduction of hip: maximum degree and limited by
15-45 degree (hip flexed) and other limb
Medial rotation of hip: maximum degree and limited by
30-45 degrees and ichiofemoral ligaments
Lateral rotation of the hip: maximum degree and limited by
45-60 degrees and pubofemoral ligaments
What is the function of the Q-angle
Represents the relationship and alignment between the pelvis, leg and foot. Abnormal q angle can promote injuries
Where does the hip’s blood supply come from
Femoral head by the lateral and medial circumflex arteries. Disruption can lead to avascular necrosis
Discuss the sciatic nerve
L4-S3. 10% of population sciatic nerve runs through the pirformis rather than under
What type of cartilage is in the acetabulum
Hyaline cartilage
