Chapter 7 self test (Bontrager's) Pelvic Bones 1. Four Bones of the Pelvis: - Right hip - Left hip - Coccyx - Sacrum 2. Three Divisions of the Hip Bone: - Ilium - Ischium - Pubis 3. Innominate Bone: - Another name for one half of the pelvic girdle, also known as the hip bone or ossa coxae. 4. Largest Foramen in the Body: - Obturator foramen Bony Landmarks - Not a Palpable Bony Landmark: - Lesser Trochanter (palpable landmarks include Greater Trochanter and Ischial Tuberosity) Ischium Aspects 1. Two Aspects of the Ischium: - Body - Ramus Pelvic Divisions 1. Imaginary Plane Separating False from True Pelvis: - Pelvis brim 2. True Pelvis: - Lesser Pelvis - Cavity - Part that forms the actual birth canal - Part found below the pelvic brim 3. False Pelvis: - Greater Pelvis - Supports the lower abdominal organs - Formed primarily by the ala of the ilium Pelvic Angles and Characteristics 1. Male Pelvis Characteristics: - Pubic Angle: Acute angle, less than 90 degrees - Heart-Shaped Inlet: Oval shape - Pubic Arch: Acute (less than 90 degrees) - Iliac Wings: Less flared Femoral Anatomy - Fovea Capitus: Small depression near the center of the femoral head where a ligament is attached. Joint Positions - Most Posterior Structure: - Sacroiliac joints (compared to other structures like the union of the acetabulum and symphysis pubis). Imaging Techniques and Pathologies 1. Device for Axiolateral (Inferosuperior) Projection of the Hip: - Wedge compensating filter to equalize density (brightness) of the hip region. 2. Modality for Assessing Joint Stability in Infants: - Sonography 3. Pathological Conditions: - A geriatric patient with an extremely rotated lower limb may have a fractured proximal femur. - Ankylosing spondylitis could result in early fusion of the sacroiliac (SI) joints. - Metastatic carcinoma usually presents with numerous small lytic lesions. - Developmental Dysplasia of the Hip (DDH) indicates increased hip joint space and misalignment. - Pelvic ring fracture is indicated by bilateral radiolucent lines across bones and misalignment of SI joints. Early fusion of SI joints and "Bamboo spine" are clinical indications of what? ️Ankylosing spondylitis Epiphyses appear shorter and epiphyseal appearing wider are clinical indications of what? ️SCFE Hallmark sign of spurring and narrowing of joint space are clinical indications of? ️Osteoarthritis
