GENERAL HIP ANATOMY Rated 5 stars

Document Content and Description Below

General Hip Anatomy  Joint consists of articulation between the head of the femur and the acetabulum  Acetabulum o formed from three bones  ilium  ischium  pubis  Ball-and-soc... ket type of joint which can move in all planes o Flexion/Extension o Abduction/Adduction o Medial/lateral rotation (internal/external)  High level of stability created by: o bony architecture o acetabular labrum and hip capsule which deepen the socket  Labrum is a soft cartilage that surround the acetabulum. It protects the joint surface and deepens the joint to provide more stability o Musculature and ligaments  High level of similarity to shoulder joint o Ball and socket joint o Can move in all planes o Hip joint is significantly more stable than the shoulder joint due to deeper socket and supporting ligaments, and musculature https://www.britannica.com/science/hip This study source was downloaded by 100000827141222 from CourseHero.com on 09-09-2021 19:02:13 GMT -05:00 https://www.coursehero.com/file/54061336/Anterior-Hip-Anatomy-FINAL-1docx/ This study resource was shared via CourseHero.com Hip Ligaments  Ligamentum teres o Intracapsular ligament that surrounds the foveal artery  Iliofemoral ligament o Strongest of the ligaments o Prevents hyperextension of the hip o Y shape in appearance and originates at the anterior inferior iliac spine and inserts at intertrochanter line of the femur  Pubofemoral ligament o Triangular in shape between superior pubic rami and intertrochanter line of the femur o Prevents excessive abduction and extension  Ischiofemoral ligament o Between ischium and the greater trochanter of the femur o Prevents hyperextension and holds the femoral head in the acetabulum Nerve Involvement  The muscles of the hip and pelvic girdle are innervated from the lumbar and sacral plexus which is known collectively as the lumbar sacral plexus. The anterior divisions of nerves include: o Obturator nerve o Femoral nerve o Tibial nerve (a division of the sciatic nerve that runs more anteriorly than posteriorly).
