Q

What is a bowing fracture?

A

A fracture that occurs when the bone bends without a clear fracture line. It occurs in children due to pliability of pediatric bones.

Q

What causes a toddler’s fracture?

A

Ususally a result of a twist in the lower leg, often when running or falling. It could happen if the child’s leg is caught and they twist their leg to free it.

22
Q

What injury might happen if an adult pulls a falling child up by the hand?

A

Nursemaid’s elbow - radial head subluxation

23
Q

What is the mechanism of injury in nursemaid’s elbow?

A

The traction from pulling on the radius moves the radial head distally from the elbow joint, trapping the annular ligament between the radial head and the capitellum

24
Q

What is the clinical presentation of nursemaid’s elbow?

A

The child will not use the affected arm. The child will have no pain at rest, no tenderness to palpation. The arm will be at the child’s side pronated and partially flexed. Movement is painful.

25
Q

How do you treat nursemaid’s elbow?

A

Hyperpronation or supination flexion methods to pop the ligament back in place

26
Q

What is a slipped capital femoral epiphysis?

A

An injury that results from instability of the proximal femoral growth plate, resulting in slippage of the epiphysis relative to the femoral neck

27
Q

When does slipped capital femoral epiphysis normally occur?

A

In adolescents during periods of rapid growth (particularly in boys, obese patients, and patients with endocrine disorders)

28
Q

What is the clinical presentation of slipped capital femoral epiphysis?

A

Chronic knee, thigh, or groin pain with a limp. Hip is externally rotated with limited flexion and internal rotation on physical exam. X-ray shows widened growth plate with epiphyseal slippage.

29
Q

What is the treatment for slipped capital femoral epiphysis?

A

Pinning to prevent further slippage until the epiphysis closes

30
Q

A 3 y.o. girl has leg pain and a limp after falling and twisting her leg. Is she more likely to have a fracture or a sprain? Why?

A

A fracture - pediatric bones are more pliable and ligaments are relatively stronger than pediatric bone

she probably has a toddler’s fracture of her distal tibia

31
Q

What type of fracture is most likely to cause growth disturbance in a child?

A

A Salter-Harris type V injury (crushed growth plate) because it completely destroys the growth plate

32
Q

What are the differences in radiographic appearance of a bowing fracture compared with a greenstick fracture?

A

A bowing fracture is when the bone bends without a clear break in the cortex.

A greenstick fracture is an incomplete fracture.

The non-broken side of a greenstick fracture can look like a bowing fracture, but the other side will have a clear break on x-ray.

33
Q

What is the main difference in trends of pediatric and adult overuse injuries?

A

Adults tend to injure tendons/ligaments because they are weaker than adult bones. Kids tend to injury bones at the physis or apophysis because their bones are relatively weaker than their tendons/ligaments

34
Q

What is Sinding-Larsen-Johansson injury?

A

Inferior patella apophysitis caused by irritation of the accessory growth area (apophysis) of the inferior patella

35
Q

What is the treatment for Sinding-Larsen-Johannson apophysitis?

A

Treatment of symptoms, stretching, patellar strap around knee

36
Q

What age groups are most affected by Sinding-Larsen-Johansson?

A

11-12 year olds

37
Q

What is Osgood-Schlatter syndrome?

A

Inflammation of the patellar ligament at the tibial tuberosity, leads to a bump on the tibial tuberosity

38
Q

What condition is suggested by this x-ray?

A

Osgood-Schlatter Syndrome (inflammation of patellar ligament at tibial tuberosity)

39
Q

What is the epidemiology of Osgood-Schlatter?

A

Boys 12-15, girls 10-13

Often athletes, often bilateral

40
Q

What is the treatment for Osgood-Schlatter?

A

Activity modification, patellar strap, PT, consider immobilization

41
Q

What does this x-ray suggest?

A

Sever disease (calcaneal apophysitis)

42
Q

What age groups are most affected by Sever disease?

A

Children aged 8-11

43
Q

What is the clinical presentation of Sever disease?

A

Mild weakness with ankle dorsiflection, pain in the heel, tight calf muscles, presents like a childhood version of achilles tendinopathy (but not in the tendon, in the bone)

44
Q

What does this x-ray suggest?

A

Anterior superior iliac spine apophysis avulsion fracture

45
Q

What is the treatment for apophysis avulsion injuries?

A

Rest, physical therapy, return to sports after a few months

46
Q

What does this x-ray suggest?

A

Little league elbow - medial epicondyle apophysitis

47
Q

What is the typical clinical presentation of little league elbow?

A

A child who pitches for little league with medial elbow pain and swelling with an insidious onset

48
Q

What is the treatment for little league elbow?

A

Rest and PT

49
Q

What is little league shoulder?

A

Proximal humerus epiphysiolysis, often caused in catchers on little league teams. Leads to widening of physis in the shoulder (humerus)

50
Q

What does this x-ray suggest?

A

A buckle or torus fracture (subtle bumps along the junction of metaphysis and diaphysis in distal forearm)

51
Q

What does this x-ray suggest (on the radial side)?

A

Greenstick fracture - incomplete radial fracture

52
Q

What does this x-ray suggest?

A

Toddler’s fracture

53
Q

What does this x-ray suggest?

A

Slipped capital femoral epiphysis
