Pelvic girdle- ilium- pubis- ischiumC. Distal Bone Structure1. Femura. Longest and strongest bone in bodyb. Weak part: neckD. Body Landmarks1. Head femur2. Neck of femur3. Greater trochanter4. Lesser trochanter5. Linear aspera6. Adductor tubercle7. Gluteal tuberosity8. Medial and lateral condyles9. Lateral epicondyle10. Medial epicondyleE. Stability1. Bony architecturea. deep joint cavity and labrum2. Strong ligaments and joint capsule3. Large supportive musclesF. Support and Locomotion1. Functions in weight bearing and locomotiona. trunk is ~ 60% of body weight2. Ability to run, crossover cut, side-step cut, jump, etcG. Gait Changes with Age1. With age:a. decrease in hip flex/extb. decrease in stride lengthc. decrease in plantar flexion of ankled. decrease in elevation of forward limb2. Change in gait —> increased risk for falls —> hip fracturesH. Joint Structure1. Deep socket2. Acetabular labruma. increase stabilityI. Ligaments1. Strong ligament supporta. Iliofemoral- prevents hyperextemsionb. Pubofemoral- limits excessive extension and abductionc. Ischiofemoral- limits internal rotationd. Ligament of headJ. Hip Motions1. Flexion-extension2. Abduction-adduciton3. Internal-external rotation4.
