Growth and development of congenitally dislocated hips reduced in early infancy
S Weintroub, I Green, R Terdiman and SL Weissman
We determined the acetabular angles, center-edge angles, comprehensive
quotients, and Shenton's lines from sequential roentgenograms of
thirty-seven children with congenitally dislocated hips treated by closed
non-manipulative reduction in early infancy. The values were compared with
those obtained from roentgenograms of 164 normal children who ranged in age
from three months to five years and of forty-three adolescents and adults.
The hip recovering from congenital dislocation developed similarly to the
normal hip but differed in that it showed a greater rate of decrease of the
acetabular angle and an increase in the center-edge angle. Significant
development after the age of five years still was manifested in the reduced
hips.
