The Hip Joint Flashcards
What Bones are Hip Joint made up from?
Pelvic acetabelum and head of Femur
What is the Classification of the hip joint?
Synovial, Ball and socket joint.
How is the Hip joint secure?
Many Ligaments; intracapsular (ligemtnous fossa)
extra capsular (iliofemoral, pubofemoral, ischialfemoral)
acteablum labrum (added depth to socket)
surrounding muscles.
Also where the ligaments are weakest there is greater support from the medial rotators.
What is the function of the Hip Joint?
Weightbearing (largest WB joint in body) and connection from lower limb to pelvic girdle.
Name the ligaments in the HIP
Intra- Ligament of the head of the femur
extracaspular- Iliofemoral, Ischialfemoral, Pubofemoral
What is the nerve supply of the Hip?
Sciatic (post), femoral (ant) and obturator nerves
What are the Hip Flexors?
Psoas Major, Rectus Femoris, illiacus, Sartorious.
I-O Psoas Major?
Origin: Trans Process of L1-5 and Vertebral body of T12-L5
Insertion: Lesser Trochanter
Nerve Supply: L1-L3
I-O Illiacus

What are the Lateral Rotators of the Hip?
Lateral Rotator Group includes 6 muscles (Pirifomis, obturator internus and externus, Gemallis inferior and superior and Quad Femoris. All of these muscles originate around the Pelvis and insert into the greater trochanter.
What are the internal rotators of the Hip?
Glute Med and Min, TFL, Adductor brevis and longus support with Superior Portion of adductor Magnus.
