2ObjectivesExplain the importance of the hip and pelvis as a support structure for the human body.Describe the skeletal structure of the hip and pelvis.List the primary muscles of the hip and pelvis.Describe common injuries associated with the hip and pelvis.
3Hip Anatomy Ball and socket joint Head of femur fits into the acetabulumStrongest joint in the bodySupported by muscles, ligaments, and tendons
4PelvisFunction of pelvis is to transmit weight from axial skeleton to legsAttachment for many muscles of the legHouses digest and urinary tractsHouses reproductive systemsImportant differences between males and females
5Pelvis Ilium: broad, flared bone of the upper and lateral pelvis Iliac Crest: upper ridge of iliumSacrum: part of the vertebral column between lumbar vertebrae and coccyx; composed of five fused vertebraeIschium: bears body weight when sittingObturator foramina: openings for blood vessels and nervesPubis: front of pelvis below the bladderCoccyx: 3-5 verebrae, tailbone
7Males vs Females Male Female narrower, heart-shaped pelvic inlet narrower sciatic notchnarrower angle where the two pubic bones meet in frontFemaleopen, circular pelvic inletbroader sciatic notchwider angle where the two pubic bones meet in frontmore outwardly flared hip bonesMale on the left. Female on the right.Women’s are less dense and smaller, shorter, and wider.
10Hip Flexor StretchWith the leg to be stretched behind the other leg and rotated slightly outward, shift weight to the other leg. Posture is erect with hips thrust forward.Kneel on a towel, then thrust forward with the hips, maintaining an erect posture.
11Quad StretchIn standing or sitting position, grab ankle and bring leg into knee flexion. Keep torso and hip erect.
12Hamstring Stretch Seated hamstring stretch Seated hamstring stretch with other leg danglingStanding hamstring stretchStanding hamstring stretch on bar
13Hamstring StretchSupine hamstring stretch: grasp behind knee and bring knee to chest, slowly straighten out leg, point toes toward you
14Adductor StretchingIn a seated position, pull the heels in as far as possible, then lean forward and push down on knees
15Piriformis StretchIn supine position, place heel of leg to be stretched on other knee. Bring knee to chest. Push knee of stretched leg away for a better stretch.
