closed

hip/pelvic girdle movement is necessary for ____ ___ movement

provides initiation of movement and stability/balnce

distal joint

what is the hip joint also called

acetabular femoral

hip joint is relatively stable due to

bony architecture

strong ligaments

large supportive muscles

what functions does the hip joint do

• enhanced substantially by its wide ROM

weight bearing

locomotion

hip joint is a ball and socket joint connected by

head of femur connecting with acetabulum of pelvic girdle

pelvic girdle is connected by

right and left pelvic bone joined together posteriorly by sacrum

what are the pelvic bones

ilium

ischium

pubis

what is the sacroiliac (SI) joint

• sacrum between the two pelvic bones and forms the SI joint

• strong ligaments unite these bones to form rigid, slightly movable joints

• synovial gliding or plane joint (limited motion)

• common site for low back injury

how is the female pelvis different

lighter, thinner

wider in area

wider, flatter sacrum

two pelvic bones join to form what

amphiarthrodial articulation

cuplike area of the pelvis composed of 3 pelvic bones

similar to glenoid fossa of shoulder

lined around most of its periphery with a labrum to enhance stability and provide some shock absorption

aids in buttress effect

approximately 70 % of the head of the femur articulates with this

acetabulum

attaches from deep in acetabulum to a depression in femoral head 

slightly limits adduction

ligaments of femur (round ligament or teres ligament)

what are the structural support for the coxofemoral (hip) joint

iliofemoral ligament

pubofemoral ligament

ischiofemoral legament

what does the neck of the femur do

holds the femur away from the pelvisw

what is the neck of the femur made of

formed by cancellous trabecular bone and reinforced with cortical bone

particularly on the inferior portion

measured in the frontal place and typically ranges from 90-135 degrees with 125 considered average

angle of inclination

angle of femur and pelvis articulation

coxa vara

angle of femur and pelvis articulation

coxa valga

the angle of femoral neck in the transverse plane is termed the

normally the femoral neck is rotated anteriorly 12-15 degrees with respect to the femur

the varus/valgus and the anteversion/retroversion position will also influence distal joints at the knee and the ankle

angle of anteversion

excessive anteversion

retroversion

what is the normal femoral neck anteversion

what is the increased femoral neck anteversion

what is the femoral neck retroversion

15 degree angle of FNA

45 degree angle of FNA

0 degree angle of FNA

right hip 

left hip

lumbar spine

movement in the coxofemoral joint

anterior movement of upper pelvis, iliac crest tilts forward in a sagittal plane, anterior tilt, downward rotation

anterior pelvic rotation

posterior movement of upper pelvis, iliac crest tilts backwards in a sagittal plane; posterior tilt; upward rotation

posterior pelvic rotation

in frontal place left pelvis moves inferiorly in relation to right pelvis; either left pelvis rotates downward or right pelvis rotates upward; left lateral tilt

left lateral pelvic rotation

in frontal plane right pelvis moves inferiorly in relation to left pelvis; either right pelvis rotates downward or left pelvis rotates upward; right lateral tilt

right lateral pelvic rotation

in horizontal/transverse plane pelvis rotates to body’s left; right iliac crest moves anteriorly in relation to left iliac crest, which moves posteriorly

counterclockwise

left transverse pelvic rotation

in horizontal plane pelvis rotates to body’s right, left iliac crest moves anteriorly in relation to right iliac crest, which moves posteriorly

clockwise

right transverse pelvic rotation
