32
Q

What is a fracture of the posterior arch in the lower lumbar spine due to overuse (stress, fatigue)?

A

Spondylolysis

33
Q

What is a defect/fx in the posterior arch with anterior displacement of the vertebral body?

A

1st born
Breech birth (legs first)
Female gender
Family hx

35
Q

Besides a positive Barlow and Ortolani, what are some findings on PE that might indicate DDH?

A
  • Galeazzi test or Allis sign: It is performed by flexing an infant’s knees when they are lying down so that the feet touch the surface and the ankles touch the buttocks. If the knees are not level then the test is positive
  • inguinal folds extending beyond the anal aperture
36
Q

What are the age ranges for US vs X-ray for peds with DDH?

A

<4-6wks US

|&raquo_space;4-6wks X-ray

37
Q

DDH tx for peds pt 0-6months? 6-12 months?

A
  • Pavlik Harness for 0-6 months

- Closed reduction w/ hip spica cast for 3-4 months

38
Q

What are 4 complications of DDH if undiagnosed?

A

Avascular necrosis
Deformed femoral head
Leg length discrepancy
Early onset arthritis

Osgood Schlatter’s dz

49
Q

How do you treat the bony growth on the anterior tuberosity of the tibia seen in Osgood-Schlatter’s dz?

A

Resolves when growth plates close at 14-16 yoa
RICE
Nsaids
PT

50
Q

Your adolescent patient presents with heel pain right where the achilles inserts into the calcaneus. The pain is relieved with RICE and nsaids. What do you suspect for a dx?

A

Sever’s Apophysitis

51
Q

Your adolescent (>10yoa) patient presents with knee pain. You dx it as Osgood-Schlatter’s dz. What other dz accompany’s Osgood-Schlatter’s that also affects the knee?

A

OCD (osteochondrosis dessicans): ostenecrosis of subchondral bone

52
Q

Your pediatric patient, who plays baseball, presents with elbow pain at the medial epicondyle apophysis. What is at the top of your ddx?

A

Little Leaguer’s elbow akak “lateral epicondylitis”

53
Q

Besides inflammation at the medial epicondyle apophysis, what fractures might you see in a peds pt with lateral epicondylitis?

A

Avulsion fx of lateral epicondyle

Lateral compression of radial head and capitellum

54
Q

Your peds pt presents with her mother who says she was swinging her daughter by her arms when her daughter started crying. After stopping the slinging motion, the daughter holds her arm against her body in pain. You suspect nursemaid’s elbow where the radial head slips under the annular ligament in a subluxation. How do you treat this pt?

A

Lots of morphine (jk)

Place thumb of one of your hands on the radial head that is subluxed. With your other hand, extend the arm in a supination movement, then flex the arm. You should feel the radial head slip back into place with your thumb as you provide pressure. Place the arm across the child’s chest and place in sling.
