- Clubfoot aka?
- Anatomic changes 3
- Treatment? 2
- Talipes equinovarus
- Talus plantar flexed

Developmental Dysplasia of the Hip (DDH)
- What is the injury?
- Caused by? 2
- Wide range of presentations? 4
- Loss of normal femoral head-acetabular relationship/stability
- Caused by physiological and mechanical factors
- Ligamentous laxity, hormonal and familial factors
- Breech position and congenital deformities - Wide range of presentations:
- Hip that is reduced but is unstable and can be dislocated
- Dislocation that can be reduced
- Fixed dislocation that cannot be reduced
- Bony deformities that require surgery
What are the tests for congenital hip dysplasia?
2
What if you have the lack of full abduction?
- Barlow test
Hip reduced but can be dislocated - Ortolani test
Hip is dislocated but can be reduced
Lack of full abduction – hip is out and can’t be reduced
TREATMENT of DDH
- If hip can be reduced?
- If hip will not stay in?
- When should we confirm with ultrasound? 2
- IF it still wont stay in what do we need to do?
- If hip can be reduced, harness or pillow first 6 months of age
- reduce under anesthesia, hold with spica cast
- Confirm reduction with ultrasound after 3 weeks
- Femoral head not visible on x-ray for 4 – 6 months
- Still won’t stay in, will need surgery
- Femoral and/or acetabular osteotomy
If femoral head can be held in normal relationship with socket

- CORRECT RESULTING DEFORMITY? 1
- Relative rest
- Braces, crutches
- Traction
- Adductor muscle release
- Femoral and/or acetabular osteotomy

- Definition: Lateral curvature of the spine >10˚ by Cobb method
- Types:
- Idiopathic
- Congenital
- Secondary
- Neuromuscular
Idiopathic Scoliosis
forms? 3
80-90% of this is found in what age group?
- Lumbar
- Thoracic
- Thoracolumbar
Adolescent (10 years- end of growth) 80-90%
- Definition of Adolescent Idiopathic Scoliosis?
- Typically what part of the spine?
Most common type
- Lateral curvature of spine with rotation in child >11 yrs. with no obvious cause
- Typically right thoracic curve
Adolescent Idiopathic Scoliosis
screening and investigations
When do you become concerned with scoliosis?
- Adam’s forward bend test
- Radiographic examination
- MRI
25 degrees
Adolescent Idiopathic Scoliosis screening and investigations 1. Adam’s forward bend test- what does it look like? 2. Radiographic examination- what kind? 3. MRI - Useful for what? 3
- Diving position
- AP & lat full length
of spine while standing - Useful if
-neurological deficits,
-neck stiffness or
-headache
- What is kyphosis?
- Usually seen in what gender?
- How does it correct?
- What is Scheuermann’s disease?
- PP?
- Usually seen in who?
- How is it corrected?
- Increased thoracic curvature in the saggital plane -Postural
- Usually seen in girls
- Gentler, more pliable curve
- Corrects with time/bracing
- Osteochondrosis of the spine
- Ring apophyses do not develop normally, resulting in wedged vertebra
- Usually seen in boys
- Sharper, more rigid curve
- May need surgical correction
Gower’s Sign: indicates what?
weakness of the proximal muscles, namely those of the lower limbs. The sign describes a patient that has to use their hands and arms to “walk” up their own body from a squatting position due to lack of hip and thigh muscle strength.
Muscular Dystrophy
Diagnosis? 2
Treatment? 3
- Diagnosis:
- Biopsy
- Electromyography (EMG) - Treatment:
- PT/OT
- Bracing
- Surgery (Scoliosis)
Normal Musculoskeletal Variants
5
- Metatarsus Adductus
- Axial Rotation
- Idiopathic Toe Walking
- Pes Cavus (Flat Foot)
- Angular Variations
- Genu Varus (Bow Legged)
- Genu Valgus (Knock-knees)
Most common congenital
foot deformity
Metatarsus Adductus
1. Metatarsus Adductus is what? 2. More common in what gender? 3. Right or left? 4. Most likely cause? 5. treatment?
- Excessive amount of adduction of the metatarsals relative to the long axis of the foot
- Female>Male
- Left>Right
- Most likely cause: intrauterine restriction
- 85-90% resolve spontaneously by 1 yr. old
Metatarsus Adductus
management
