Pediatric Musculoskeletal Quiz Part II

Question 1: A supracondylar fracture of the humerus is likely if there is ...
Anterior displacement of the distal fragment such that the anterior humeral line does not bisect the middle third of the capitellum.
 Posterior displacement of the distal fragment such that the anterior humeral line does not bisect the middle third of the capitellum.
Question 2: Each of the following is true of Developmental Dysplasia of the Hip (DDH) except ...

Early diagnosis of DDH is important because chronic dislocation of the femoral head can lead to growth deformity of the acetabular fossa.
 DDH is more prevalent in males than females.
 Clinical findings of DDH may include positive "clicks" with dislocation (Barlow maneuver) and relocation (Ortolani maneuver) of the hip.
 DDH more commonly involves the left hip.

Question 3: Early radiographic findings in Legg-Calve-Perthes disease include a bone scan which reveals increased activity in the femoral epiphysis.
True
 False
Question 4: Imaging findings seen in Clubfoot (or Talipes Equinovarus) include all of the following except ...
Decreased talocalcaneal angle.
 Medial displacement of the first metatarsal relative to the long axis of the talus.
 Equinus heel (fixed plantar flexion of the heel).
 Hindfoot valgus.
Talonavicular subluxation.

Question 5: Patients with Ollier disease have a higher rate of transformation to chondrosarcoma than do patients with Maffucci syndrome.
True
 False
Question 6: Osteomyelitis in the pediatric population most often ...
Shows a focal area of increased uptake in all three phases of a bone scan.
Involves the flat bones as opposed to the long bones.
 Can be detected on plain films within 2-3 days of the onset of symptoms.
 Found in children between the ages of 6 and 10.
Question 7: Classic radiographic findings in Langerhans Cell Histiocytosis include all of the following except ...
Geographic Skull.
 Floating Teeth.
Vertebra Plana.
Paddle-shaped ribs.

Question 8: Radiographic findings in Achondroplasia include each of the following except ...
A pelvis with tall, flared iliac wings and increased acetabular angles.
Shortened spinal pedicles distally with a decreased interpedicular distance.
 Rhizomelic limb shortening.
 Craniofacial disproportion with large calvarium, diminuitive skull base, small foramen magnum and small jugular foramina.
Question 9: The sclerotic metaphyseal bands (seen in cases of high lead exposure) are best shown in areas of rapid growth including the knees and wrists.
True
False
Question 10: Hemophilic Arthropathy can be distinguished from Juvenile Rheumatoid Arthritis by the presence of epiphyseal overgrowth and widening of the intracondylar notch in the knee.
True
 False
