What is gait?
A persons manner of walking

Describe the gait cycle?
What is a major complication of CP?
Major complication of CP is hip displacement and maybe dislocation:
- Risk proportional to GMFCS category

Club foot

Describe the normal curvature of the spine?
Spine normal curvature in sagittal plane:

- Lumbar lordosis
- Sacral kyphosis
What is scoliosis?
Scoliosis = any deviation in coronal plain
When does scoliosis have clinical significance?
Scoliosis = any deviation in coronal plain
Clinical significance is deviation >10o
What are the 2 kinds of scoliosis?
-
Non-structural
- Due to extrinsic cause such as leg length discrepancy or hip problem
- Resolves when causal factor is addressed
-
Structural
- Abnormal rotation of vertebrae and is an intrinsic spinal problem
- Can progress
- Risk of progression is proportional to curve magnitude (Cobb angle) and age at presentation
- 3 major classes
- Congenital (abnormalities of formation vertebrae)
- Idiopathic
- Classified by age of presentation
- Infantile <3 years
- Juvenile 3-10 years
- Adolescent >10 years
- Classified by age of presentation
- Neuromuscular
- Others include post-traumatic, degenerative, infection etc
