Cobb angle
The standard radiographic measurement used to quantify the degree of spinal curvature in scoliosis patients.
MCAD
A group of skeletal dysplasias characterized by metaphyseal abnormalities with normal epiphyses and spine.
metaphyseal corner fracture
A specific fracture pattern in infants highly suggestive of non-accidental trauma.

physeal arrest
Premature cessation of growth at the growth plate, often resulting from trauma or infection.
physeal bar
