The Hip - Intro, Arthrolgy And Muscles Flashcards
What does the hip need to do?
=) mobility
⇒ strength
⇒ support and stability
What structure is the hip
① A ball and socket joint, multiaxial movement, deep socket and labrum
2 angle of neck leverage, easier to shift weight from one leg to the other.
Hip movement - what planes and movement occur where?
① in the Sagittal plane / flexion and extension occurs.
② in the frontal plane, addiction and abduction occurs
3 in the transverse plane, external and internal rotation occurs.
What makes up the pelvic girdle
① the ilium
② the pubis
③ ischium
What is the lunate surface
Part of the acetabulum covered with particular cartilage
What does the synovial membrane do?
The synovial membrane secretes synovial fluid into the joint, it is important for lubrication and nutrition
What does the labrum do?
The labrum increases stability between ball and socket, holds the femur in more steady to the joint.
What are the ligaments in the hip?
① pubofemoral ligament, goes from pubis to the femur
② illiofemoral ligament, goes from ilium to femur, larger ligament
③ ischiofemoral ligament, goes from ischium to femur, support underneath.
④ inguinal ligament, important land mark for nerves and arteries pass a Cross the hip, runs between the ASIS down to the pubic tubule.
What is the iliopectineal bursa fuel the trochanterie bursa
The iliopectineal bursa is a small fluid sacks that reduce friction where you have soft tissue, muscles, tendons.
The trochanteric bursa protects tendons in glutes.
What compartments are flexors, extensors, abductors, adductors, in?
Anterior compartment = flexors
Posterior compartment = extensors
Medial compartment = adductors
Lateral compartment = abductors
What are the 5 hip flexor muscles?
2 penguins 🐧 R in space🪐
① iliacus muscle
② Psoas major
③ pectineus muscle
④ Rectus Femoris muscle
⑤ sarturius muscle
Igloo Penguins
2 Penguins R in space
Iliacus muscle
Origin = iliac crest
Insertion = lesser trochanter
Intervention = femoral nerve
Psoas major
Origin = vertical bodies t12 - L5
Insertion = lesser trochanter
Pectineus muscle
Origin = pubic ramous
Insertion = pactinear line of the femur
Innervention = femoral nerve
Rectus femoris muscle
Origin = ASIS
Insertion = tibial tuberosity
Intervention = femoral nerve
