The Pelvic Girdle and Hip Joint
The hip joints functions are?
Weight bearing Locomotion (enhanced by wide ROM)
Bony architecture of hip joint
acetabulum forms relatively deep socket for femoral head (compare to glenohumeral joint)
Hip joint muscles medial
adductor brevis, adductor longus, adductor magnus, gracilis
Hip Joint is what kind of joint?
ball and socket
Hip joint muscles posterior
biceps femoris ,semitendinosus, semimembranosus, gluteus maximus,
stability of hip joint. relativity of stable joint
bony architecture ligamentous support muscular support
The hip joint is fairly stable due to?
bony architecture large ligaments large supportive muscles
Bones of the hip join anterior femur
femoral head acetabulum greater trochanter femoral neck lesser trochanter femur
Hip joint muscles lateral
gluteus medius, gluteus minimus, tensor fasciae latae
What does the hip joint articulate with ?
head of the femur articulates with the acetabulum of the pelvic girdle
Hip joint muscles anterior
iliacus , psoas, rectus femoris, sartorius, pectineus
Ligamentous support if hip joint, 3 main ligaments
iliofemoral ligament Pubofemoral ligament ischiofemoral ligament
22 main muscles that cross the hip joint
increases joint stability
Pelvic Bone
made up of: illum ischium pubis
bones of the hip joint articulate between?
pelvic bone and femur
ischiofemoral ligament
posterior prevent excessive internal rotation
Posterior Pelvic Joint
sacroillac articulates with the 2 pelvic bones
Anterior Pelvic Joint
symphysis pubis
Acetabular femoral joint
Head of femur sits in acetabulum enarthrodial joint (freely moveable) Multiaxial
Symphysis Pubis is what type of joint?
amphiarthroidal joint (little movement)
pubofemoral ligament
anteriomedially, inferiorly prevents exc
iliofemoral ligament
anterior prevents hyperextension
compared to males ,females pelvic girdles tend to be:
lighter thinner wider flares out laterally at front wider sacrum broader pelvic cavity
Pelvic Girdle
right and left pelvic bone joined together by the sacrum
