Hip Joint

Hip joint (femur and acetabulum of pelvis)


Hip joint and pelvic girdle work together much like
shoulder joint and girdle


Relatively stable due to:
 Bony architecture
 Strong ligaments
 Large supportive muscles
Pelvis moves in response to trunk and/or thigh movement
Other bones to consider


Tibia
Fibula
Patella
Pelvic Girdle


Pelvic girdle  Pelvic bones, sacrum, coccyx
Pelvic bones:



Sacrum:


Each pelvic bone is made up of three fused bones  ilium,
ischium, & pubis
Right & left pelvic bone joined together posteriorly by sacrum
Extends from spinal column with 5 fused vertebrae
Coccyx:

Extends posteriorly from sacrum with 3 fused vertebrae
