Q

1 - Describe the radiographic findings?

2 - Give 3 different differentials.

3 - Choose one and outline your reasoning behind your diagnosis and radiographic findings.

A

1 -

Osteopaenia (widespread) enlargement of bones and epiphysis regions.

Eggshell thin cortices

Reactive sclerosis

Increased soft tissue density

Pseudocysts

Erosive changes - anteroinferior and posterosuperior calcaneus = interruption to cortices

2 -

Charcots joint

JRA

Osteogenesis imperfecta

Haemophilia

3 -

Juvenile RA - Causes enlargement of the epiphyseal regions. Also results in osteopaenia due to disuse or medications. Cortical thinning

Haemophilia - Juxtaarticular osteopaenia, haemarthrosis could cause the osteopaenia, joint disorganisation, cortical thinning, osteophytes.

20
Q
  1. What is the diagnosis
  2. What is the arrow pointing at?
  3. What is the common age bracket for this patients condition?
  4. Any other radiographic findings?
A
  1. Perthes or Dwarfism
  2. Sagging rope sign - intertrochanteric line
  3. 3-12
  4. Buttressing of femoral head, mushroom cap deformity, coxa magna, coxa vara
21
Q
  1. What is this congenital malformation called?
  2. Is it clinically significant?
    3.
A
  1. Pectus carinatum
  2. Yes, the restriction of the ribs could alter lung capacity - low tidal volume predisposes to pneumonia

  2. What is the condition?
A
  1. Flattened pelvis (champagne glass pelvis), mushroom cap femoral head, coxa magna, enlargement of lesser trochanter, diverticuli
  2. Dwarfism

Levator scapulae

Latissimus dorsi

Trapezius

Deltoid

Pec minor

24
Q

This is the L4/5 disc space

  1. Which nerve root is displaced?
  2. What reflexes would be affected
  3. What muscles are affected by this nerve root?
  4. What is A, B, C and D
A
  1. L5
  2. Achilles
    • gluteus maximus muscle mainly S1.
    • gluteus medius muscle.
    • gluteus minimus muscle.
    • tensor fasciae latae.
    • tibialis anterior.
    • tibialis posterior.
    • extensor digitorum brevis.
    • extensor hallucis longus.
  3. A = left L4 nerve root, B = right common iliac artery, C = Colon, D = facet
25
Q
  1. What is the arrow pointing at?
  2. Is this clinically significant?
  3. Provide 1 other radiographic finding?
  4. What is the type of study?
A
