Hip Joint Flashcards
The hip joint is what type of joint
Ball and Socket Synovial Joint
What is the acetabular Labrum?
Fibrocartilaginous Collar
Which part of acetabular cavity does acetabular labrum cover?
Lunate Surface
Depth of acetabulum is increased by
fibrocartilaginous acetabular labrum.
Name the 3 Ligaments of the Hip Joint
Iliofemoral, Ischiofemoral and Pubofemoral
The ileofemoral ligament prevents
Hyperextension of Hip
The pubofemoral ligament prevents
Hyper Abduction of Hip
The movements at the hip joint are
Flexion Extension Abduction Adduction Internal Rotation External Rotation Circumduction
Name the 3 Hip Flexors
Iliacus
Psoas Major
Pectineus
The iliacus and posts major arise from
Inner Pelvis and Posterior Abdo Wall
At what point are Iliacus and Psoas Major known as Iliopsoas Muscle
When they attach onto greater trochanter of femur
The Pectineus arises from
Pubis Bone passing distally to attach onto femur
The hip flexors (iliacus, poses major and pectineus) are supplied by
Branches from Lumbar Plexus
What are the 3 Hip Extensors
Gluteus Maximus
Hamstrings
Posterior Part Adductor Magnus
The Hamstrings are comprised of how many muscles
3
What is the main extensor of hip joint
Gluteus Maximus
The Hip flexors are supplied by branches from
Sacral Plexus L4-S3
The gluteus Maximus, Hamstrings and Posterior Adductor Magnus are supplied by
branches of sacral plexus L4-S3
The gluteus Maximus, Hamstrings and Posterior Adductor Magnus are supplied by
branches of sacral plexus L4-S3
Where are the Hip Adductors found
Medial Thigh
The adductor compartment of hip is supplied by
Obturator Nerve (aside from posterior adductor Magnus)
The obturator nerve exits the pelvis via
Obturator Canal
Name the 5 Hip Adductors
Adductor Longus Brevis and Magnus Pectineus Gracilis Obturator Externus
Name the Hip Abductors
Gluteus Medius and Minimus
Piriformis
Tensor Fascia Latae
Which muscles carry out Hip Abduction
Deep Gluteal Muscles via attachment to greater trochanter of femur
Name the Abductors of Hip Joint
Gluteus Medius and Minimus
Piriformis
Tensor Fascia Latae
which muscles are essential for normal walking gait
Abductors of Hip Joint
What happens every time you raise one leg off ground, the abductors of what side of pelvis contract to provide stability
Opposite side
The hip abductor compartment is supplied by branches of what plexus
Lumbosacral Plexus
Turning the inside of the foot to face forward requires
internal rotation of hip
Turning the inside of the foot to face backwards requires
External rotation of hip
Muscles involved in external rotation crosses the joint on
Posterior side
Muscles involved in external rotation crosses the joint on
Posterior side
Name the five muscles involved in external rotation
Piriformis Obturator Internus Obturator Externus Sup and Inf Gamelli Quadratus Femoris
Muscles involved in internal rotation cross joint on which side
Anterior Side
Which muscles are medial rotators of hip joint
Gluteus Medius
Gluteus Minimis
Tensor Fascia Lata
Which muscle forms the main bulk of anterior thigh region
Quadriceps
What are the four heads of quadriceps femoris
Rectus Femoris
Vastus Lateralis
Vastus Intermedius
Vastus Medialis
Which nerve innervates anterior thigh muscles
Femoral Nerve
