The Hip And Pelvis Flashcards
(142 cards)
What makes the hip strong?
-articulate surface congruency (congruent in all positions)
-strong ligaments around the joint
-strong muscles
What is the closed-pack position of the hip?
-maximum extension
-medial rotataion
-abduction
What is the open-packed position of the hip joint?
-slight flexion
-abduction
-lateral rotation
What are active ranges of movement?
The movement range of a joint undertaken by the person themselves
What are passive ranges of movement?
The same physiological movement as active but with no effort of the person (all done by a therapist)
What movements can occur from the hip joint?
Flexion/extension
Abduction/adduction
Medial rotation/lateral rotation
What is an accessory movement?
A movement that a person can’t perform actively, but which can be performed on that person by an external force
What accessory movements are available at the hip?
Longitudinal Caudad (pulling leg to tail)
Distraction (taking the head of the femur out of the acetabulum
Antero-posterior (gliding backwards)
Posters-anterior (gliding forwards)
What are the names of the muscles responsible for hip flexion?
Psoas Major
Sartorius
Illiacus
Pectineus
Rectus femoris
Gracillis
What are the names of the muscles responsible for hip extension?
Gluteus maximus
Adductor Magnas (ext part)
Biceps femoris
Semimembranosius
Semitendinosus
What are the names of the muscles responsible for hip abduction?
Gluteus Med and Min
Sartorius
TFL
Piriformis
What are the names of the muscles responsible for hip adduction?
Adductor longus
Adductor brevis
Adductor Magnus
Pectineus
Gracilis
What are the names of the muscles responsible for medial rotation?
Gluteus Med and Min
TFL
Adductor Magnus
What are the names of the muscles responsible for hip lateral rotation?
Gluteus Maximus
Piriformis
Obturator Int and ext
Gemellus Superior and Inferior
Quadratus Femoris
Sartorius
What two muscles make up Ilio-Psoas
Illiacus and Psoas-Major
What is special about Ilio-Psoas?
It is a conjoined muscle
Where is the origin of Iliacus?
Iliac fossa (not extending onto the iliac crest)
Where is the origin of Psoas-Major?
Transverse processes T12-L4
Where does Ilio-Psoas insert?
The lesser trochanter
What action does the Ilio-Psoas provide?
Hip flexion/ trunk flexion at hip
(Trunk flexion occurs when feet are in fixed position)
What is the innervation of a muscle?
The supply or distribution of nerve fibres to any part of the body
What is the innervation of Ilio-Psoas?
L2-L3
Where is the origin of the Pectineus?
Superior pubic rami
Where does the Pectineus insert?
Lesser trochanter to the proximal aspect of linea aspera
