Q

What are the symptoms of osteogenesis imperfecta?

A

Fractures can occur with minimal force – this varies from child to child.

Bones may have an altered shape, for example, they may be shortened or bowed.

The whites of the eyes may appear more blue or grey than normal.

Joints can be hypermobile or very flexible

Some degree of joint or bone pain may be present

Problems with formation of teeth (dentinogenesis, or DI)

Children with OI may tire easier than other children

Hearing problems are known to affect people with OI usually after puberty.

Children with OI tend to be shorter than other children.

Q

What is rickets?

A

Rickets is a preventable bone disease that causes weak, soft bones.

If a child has softer bones, the bones can bend and become an abnormal shape.

Rickets only occurs in growing bones,

29
Q

What is the cause of Perthes’ disease?

A

Part or all of the femoral head (top of the thigh bone: the ball part of the ball-and-socket hip joint) loses its blood supply and may become misshapen.

This may lead to arthritis of the hip in later years

30
Q

What are the symptoms of Perthes’ disease?

A

Pain in the groin, the thigh or the knee - particularly after physical activity

Limp

Restricted range of movement (stiffness) of the hip joint

These symptoms may persist on and off for many months

The disease itself lasts for a few years

31
Q

How do you diagnose Perthes’ disease?

A

Physical examination tests
Limits the ability to move the leg away from the body (abduction), and twist the leg toward the inside of the body (internal rotation)

X-rays
X-rays will show the condition of the bone in the femoral head and help your doctor determine the stage of the disease

32
Q

What is the treatment for Perthes’ disease?

A

To keep the femoral head within the acetabulum
Cast, braces

If less than 6 years
Observation

Older
Surgical management with moderate results

Operate on severe deformities

33
Q

What is Kohlers disease?

A

Kohler disease is a condition that affects a bone at the arch of the foot called the tarsal navicular bone

34
Q

What are the symptoms of Kohlers disease?

A

Swelling of the foot

Redness of the affected area

Tenderness, particularly along the length of the arch

Limp or abnormal gait (style of walking)

35
Q

What is the cause of Kohlers disease?

A

The exact underlying cause of Kohler disease is unknown.

Excessive strain on tarsal navicular bone and its associated blood vessels before the bone is completely ossified (hardened)

36
Q

How is Kohlers disease diagnosed?

A

Clinical history and examination

X-ray

37
Q

What is the treatment for Kohlers disease?

A

Resolves itself over time

Plaster cast or support

38
Q

What is discoid meniscus?

A

Healthy menisci are shaped like crescent moons (in fact, “meniscus” comes from the Greek word for crescent).

A discoid meniscus is thicker than normal, and often oval or disc-shaped. It is more prone to injury than a normally shaped meniscus.

39
Q

What is the cause of discoid meniscus?

A

The cause of discoid meniscus is not known. It is a congenital (present at birth) defect.

40
Q

What are the symptoms of a discoid meniscus?

A
  1. Pain
  2. Stiffness or swelling
  3. Catching, popping, locking of the knee
  4. Feeling that the knee is “giving way”
  5. Inability to fully extend (straighten) the knee
41
Q

What are the types of discoid meniscus?

A

Incomplete
The meniscus is slightly thicker and wider than normal

Complete
The meniscus completely covers the tibia.

Hypermobile Wrisberg
This occurs when the ligaments that attach the meniscus to the femur and tibia are absent

42
Q

How do you diagnose discoid meniscus?

A

Medical history and examination

X-ray
May appear widened

MRI
Abnormal shape

43
Q

What is the treatment for discoid meniscus?

A
  1. Knee arthroscopy
  2. Saucerization
44
Q

What is slipped captial femoral epiphysis?

A

Slipped capital femoral epiphysis (SCFE) is a hip condition that occurs in teens and pre-teens who are still growing.

For reasons that are not well understood, the ball at the head of the femur (thighbone) slips off the neck of the bone in a backwards direction.

45
Q

What age is most common for slipped capital femoral epiphesis?

A

10-15 years

46
Q

What are the different types of slipped capital femoral epiphysis?

A

Stable SCFE
In stable SCFE, the patient is able to walk or bear weight on the affected hip, either with or without crutches. Most cases of SCFE are stable slips.

Unstable SCFE
This is a more severe slip. The patient cannot walk or bear weight, even with crutches. Unstable SCFE requires urgent treatment. Complications associated with SCFE are much more common in patients with unstable slips.

47
Q

What are the symptoms of slipped captial femoral epiphysis?

A
  1. Intermittent pain in the groin, hip, knee and/or thigh for several weeks or months
  2. This pain usually worsens with activity
  3. The patient may walk or run with a limp after a period of activity
  4. Loss of internal rotation of the leg in flexion
48
Q

How do you diagnose slipped captial femoral epiphysis?

A
  1. Pain with extremes of motion
  2. Limited range of motion in the hip–especially limited internal rotation
  3. Involuntary muscle guarding and muscle spasms
  4. X-ray - BOTH HIPS
    • Head of the thighbone appears to be slipping off the neck of the bone
49
Q

What is the treatment for slipped capital femoral epiphysis?

A
  1. Internal fixation: typically a single cannulated screw placed in the center of the epiphysis
50
Q

What is Osgood-Schlatter Disease?

A

Osgood-Schlatter disease (OSD) is swelling and irritation of the growth plate at the top of the shinbone

51
Q

What is the cause of Osgood-Shlatter disease?

A
  1. The apophysis is the portion of the epiphysis which is attached to a tendon and subjected to tensile forces.
  2. In the knee, this is the tibial tuberosity where the patella tendon inserts
52
Q

What are the symptoms of Osgood-Schlatters?

A
  1. Knee pain and tenderness at the tibial tubercle
  2. Swelling at the tibial tubercle
  3. Tight muscles in the front or back of the thigh
53
Q

How is Osgood-Schlatters disease diagnosed?

A
  1. Clinical examination
  2. X-rays helpful
54
Q

What is the treatment for Osgood-Schlatters?

A
  1. NSAIDS
  2. Stretching
  3. Ice
55
Q

What is developmental dysplasia of the hip?

A

Developmental dysplasia of the hip (DDH) is a condition where the “ball and socket” joint of the hip does not properly form in babies and young children.

56
Q

What are the risk factors for developmental dysplasia of the hip?

A
  1. Female sex: 6 times greater risk
  2. Breech presentation
  3. Positive family history
  4. Firstborn children
  5. Oligohydramnios
  6. Birth weight > 5 kg
  7. Congenital calcaneovalgus foot deformity
57
Q

What is the cause of developmental dysplaisa of the hip?

A

In DDH, the socket of the hip is too shallow and the femoral head is not held tightly in place, so the hip joint is loose. In severe cases, the femur can come out of the socket (dislocate).

58
Q

What are the symptoms of developmental dysplasia of the hip?

A
  1. Developing a limp
  2. Hip pain – especially during the teenage years
  3. Painful and stiff joints (osteoarthritis)
59
Q

How is developmental dysplasia of the hip diagnosed?

A

Barlow and ortolani
Test within 72 hours

Ultrasound

More than 4.5 years
X-ray

60
Q

What is the management for developmental dysplasia of the hip?

A
  1. Most unstable hips will spontaneously stabilise by 3-6 weeks of age
  2. Pavlik harness (dynamic flexion-abduction orthosis) in children younger than 4-5 months
  3. Older children may require surgery
61
Q

What further screening is there for DDH after birth?

A

All breech babies at or after 36 weeks gestation require USS for DDH screening at 6 weeks regardless of mode of delivery

62
Q

What is Juvenule idiopathic arthritis?

A

Juvenile idiopathic arthritis, formerly known as juvenile rheumatoid arthritis, is the most common type of arthritis in children under the age of 16.

Q

What is oligoarticular (or pauciarticular) juvenile idiopathic arthritis (JIA)?

A

Is the most common presentation of JIA and is defined as affecting up to four joints

Family history for autoimmune disease (systemic lupus erythematosus in this case) is a risk factor for JIA.

64
Q

What is the cause of juvenile idiopathic arthritis?

A

Juvenile idiopathic arthritis occurs when the body’s immune system attacks its own cells and tissues.

It’s not known why this happens, but both heredity and environment seem to play a role
