Flashcards in Hip, buttock and thigh Deck (81)
What happens to the lower limb during development?
It twists during develop and you get a permanent pronation at the mid-thigh level
What specific words are given to the flexion and extension of the foot?
Dorsiflexion (pointing toes up)
Plantarflexion (pointing toes down)
What are the three parts of the pelvis (hip bone)?
What marks the ends of the iliac crest?
ASIS and PSIS
What is the name given to the surface of the hipbone that articulates with the sacrum?
What lies in between the greater and lesser trochanters?
What short ridge is found just inferior to the lesser trochanter?
A longer ridge downwards along the shaft of the humerus and originates from the short ridge below the lesser trochanter. What is this long ridge called?
Which tubercle is found just superior to the medial epicondyle?
What is the anterior protrusion between the ilium and the pubis called?
What are the two notable parts of the ischium onto which ligaments attach?
Tuberosity and spine
Which pelvic bones make up the acetabulum?
All three of them (ilium, ischium and pubis)
What notches are present on the posterior aspect of the pelvis?
Greater sciatic notch and lesser sciatic notch
What is the angle of inclination?
The angle that the long axis of the shaft makes with the long axis of the head and neck
What determines the size of the angle between the long axis of the shaft and the vertical plane?
The width of the hips
What structures form the greater and lesser sciatic foramina?
What are the two fascia found in the thigh?
Superficial fascia – e.g. subcutaneous tissue
Deep fascia – fascia lata
What is the name given to the lateral thickened area of the fascia lata?
What are the four compartments of this region?
Anterior compartment of the thigh
Medial compartment of the thigh
Posterior compartment of the thigh
What movements are the muscles of the gluteal region responsible for?
Extension, abduction and external rotation of the femur
What are the gluteal muscles?
(tensor fasciae latae – this is neurologically a gluteal muscle (innervated by superior gluteal nerve) but functionally it is more of an anterior compartment muscle)
What are the short external rotators of the hip?
Gemelli (superior and inferior)
Describe the attachments of gluteus maximus.
Proximal – posterior part of the iliac crest and thick fascia of the sacrum and coccyx
Distal – gluteal tuberosity and ilio-tibial tract
What proportion of the gluteus maximum fibres attach to the gluteal tuberosity?
About 25% attach to the gluteal tuberosity and the rest are attached to the ilio-tibial tract
What does the ilio-tibial tract insert into?
Anterolateral tubercle of the tibia
NOTE: there is a lateral intermuscular septum that goes between the iliotibial tract and the posterior surface of the femur
Describe the attachments of gluteus medius.
Proximal – broad attachment to the external surface of the ilium (between the anterior and posterior gluteal lines)
Distal – greater trochanter
Describe the attachments of gluteus minimus.
Proximal – broad attachment to the external surface of the ilium (between the anterior and inferior gluteal lines)
Distal – just below the greater trochanter
What movement are gluteus medius and gluteus minimus responsible for?
What movement are the deep muscles of the gluteal region responsible for?
