Femur and Pelvic Girdle pathologies

Question 1

The first effect demonstrated is fusion of the sacroiliac joints. The disease causes extensive calcification of the anterior longitudinal ligament of the spinal column. It is progressive, working up the vertebral column.

Answer 1

Ankylosing spondylitis

Question 2

Radiographic characteristic known as “bamboo spine”

Answer 2

Ankylosing spondylitis

Question 3

Fx. occurs in adolescent athletes who experience sudden, forceful, or unbalanced contraction of the tendinous and muscular attachments such as might occur while running hurdles. The force of the tendons and muscles sliding over the tuberosities, ASIS, anterior inferior iliac spine (AIIS), superior corner of the symphysis pubis and iliac crest

Answer 3

Avulsion fx. of the pelvis

Question 4

A malignant tumor of the cartilage, it usually occurs in the pelvis and long bones of men over the age of 45.

Answer 4

Chondrosarcoma

Question 5

Hip dislocations are caused by conditions present at birth and may require frequent hip radiographs

Answer 5

Developmental dysplasia of the hip (DDH)

Question 6

What is an older term for DDH?

Answer 6

CDH (congenital dislocation of the hip)

Question 7

Disease that is the most common type of aseptic or ischemic necrosis. Lesions typically involve only one hip. The disease occurs predominantly in 5-10 year old boys and a limp is usually the first clinical sign.

Answer 7

Legg-calve-perthes disease

Question 8

Radiographs demonstrate a flattened femoral head that later can appear fragmented

Answer 8

Legg-Calve-Perthes disease

Question 9

Malignancy spreads to the bone via the circulatory system or the lymphatic system or by direct invasion. Metastatic tumors of the bone are much more common than primary malignancies. Bones that contain red bone marrow are the more common metastatic sites)

Answer 9

Metastatic carcinoma

Question 10

Degeneration of joint cartilage and adjacent bone causing pain and stiffness. Most common type of arthritis and is considered part of the normal aging process.

Answer 10

Osteoarthritis

Question 11

Osteoarthritis is also called

Answer 11

degenerative joint disease

Question 12

severe blow or trauma to one side of the pelvis may result in a fracture site away from the site of primary trauma

Answer 12

Pelvic ring fx.

Question 13

Both osteoporosis and avascular necrosis frequently lead to weakening or collapse of weight-bearing joints such as the hip joint; fx. occur with only minimal trauma

Answer 13

Proximal femur (hip) fx.’s

Question 14

This condition usually occurs in 10-16 year olds during rapid growth when even minor trauma can precipitate its development. The epiphysis appears shorter and the epiphyseal plate wider with smaller margins

Answer 14

Slipped capital femoral epiphysis
