What do parents often say when they present their child?
Clumsy and wear through shoes very fast.
55
What are the three causes of in-toeing?
Femoral neck anteversion Internal tibial torsion Metatarsus adduction
56
Femoral neck anterversion
Femoral neck is excessively anteverted (pointing forwards)
57
Common signs of femoral neck anteversion.
Lots of internal rotation and minimal external. | Sits in W position
58
What is treatment in femoral neck anteversion?
NO indication for surgery. | Simply reassure and chart progress.
59
In what demographic is internal tibial rotation common?
Toddlers 1-3 years | Usually self resolved by 6
60
Metatarsus adduction
Causes apparent in-toeing. Most are self resolving Serial casting is used in non resolving cases
61
Are flat feet part of normal variation?
Yes they usually have no underlying pathology and has no real functional issues.
62
What are they two types of flat feet?
Flexible and fixed
63
What is the cause of flexible flat feet?
Ligamentous laxity | Familial or idiopathic
64
How can you test for flexible flat feet?
Jack Test | When patient stands on tiptoes the medial arch develops
65
In adults what can cause flexible flat feet?
Tibialis posterior tendon dysfunction
66
What causes fixed flat feet?
Abnormal tarsal coalition of bones. | Cartilaginous joints between bones
67
How many adults have flat feet?
1 in 5
68
What is cavus feet?
A high arching foot with clawed toes
69
What is the worry with cavus feet?
Can indicate underlying neurological disorder
70
Culry toes
Idiopathic and generally asymptomatic curling of toes.
71
When is surgery indicated in curly toes?
Persistence in adolescents as most cases are self-resolving.
72
What is the surgery in curly toes?
Cut 1 of the two flexor tendons
73
What is the F:M proportion and which hip is more commonly affected in developmental dysplasia?
8:1 Left more than right 5 in 1000 babies
74
In which ethnic group us there a higher incidence?
Native american
75
In which ethnic group is there a reduced incidence?
African
76
Risk Factors for developmental dysplasia
``` Family History Breech presentation First born babies Down syndrome >4kg birth weight ```
77
Why are women more affected?
Women have receptors for relaxin even as neonate. In late stages of pregnancy the mother releases this to allow easier passage of baby out. However this loosened the tendons holding head of femur in place.
78
What is developmental dysplasia of the hip?
A very shallow acetabulum as a result of defective hip joint development. Sever cases a false acetabulum can occur proximal to original.
79
What can happen if developmental dysplasia is undetected?
Severe arthritis and gait/mobility is severely affected.
80
What gait is developed in late Developmental dysplasia?
Trendelburgs gait
81
What are clinical signs looked for in developmental dysplasia?
Asymmetry in leg length loss of knee height Crease asymmetry in nappy fold Less abduction
82
What are the two tests used for developmental dysplasia?
Barlows test- adduction with downwards pressure. Ortolani - Abduction with upwards lift - clunk sound
83
If barlows and Ortolani tests are positive what is the next step?
Ultrasound is used as doesn't scare the child and X ray will not be able to identify non ossified femoral head.
84
What is key to success in developmental dysplasia?
Early diagnosis
85
What is treatment for children under 18 months with unstable hips?
Pavlik Harness - worn 23-24 hours a day for 12 weeks
86
What is the success rate of a pavlik harness?
85-95%
87
What is treatment for children with persistently dislocating hips over 18 months?
Open surgery reduction
88
Why is a bilateral developmental dysplasia worse?
Cant compare hips so many of clinical signs look symmetrical so 'normal'. So later stage detection = worse symptoms
89
In children over 18 moths what is modality of choice for looking at the hip?
X-ray as the femoral head has ossified
90
Transient synovitis of the hip
Self limiting inflammation of hip
91
What is the history linked to transient synovitis?
An upper respiratory viral infection prior to presentation
92
Signs of transient synovitis
Hip lies flexed and externally rotated Pain at end range of movement Systemically well
93
What is used to diagnose transient synovitis?
Ultrasound and aspiration of the joint
94
In diagnosing transient synovitis what more serious conditions need to be disproved?
Septic or juvenile rheumatoid arthritis, aswell as Perthes disease.
95
What is Perthes disease?
Idiopathic avascular necrosis of the femoral head.
96
Who is Perthes disease more common in?
5x more men | 4-9 year olds
97
What is the progression of Perthes disease?
Transient loss of blood supply. Femoral head begins to undergo necrosis. Femoral head can collapse or fracture. Subsequent remodelling results un early arthritis.
98
Clinical signs of Perthes disease
Pain and limp and loss of internal flexion. | Late presentations will show gluteal wasting and +ve trendellenburgs test.
99
Perthes treatmnet
No treatment, simply observation using X-ray and avoidance of physical activity. Severe arthritis as a result may require hip replacement.
100
SUFE
Slipped Upper Femoral Epiphysis
101
Who does SUFE usually affect?
Overweight pre-pubertal post growth-spurt boys aged 8-10 | Girls less commen
102
What is SUFE?
The physis is unable to support the weight and the femoral epiphysis slips as a result.
103
How does SUFE present?
Groin hip or knee pain, present with antalgic gait. Loss of internal rotation. Affected limb may be shorter and lie externally rotated.
104
What X-ray orientation gives the best view?
Laterally is most likely to show degrees of slip. | LOOK FOR MELTED ICE CREAM ON A CONE!!
105
Treatment for SUFE
Urgent surgery Severe acute can undergo gentle manipulation but total hip replacement may be required. Pinning the femoral head is used if a blood supply has been preserved.
