DISLOCATION OF THE HIP IN YOUNG RATS PRODUCED EXPERIMENTALLY BY PROLONGED EXTENSION

Abstract

1. Dislocation and subluxation of the hip has been produced in young rats by application of splints reaching from the hip to the foot, bringing the hip into extension.

2. Progressive acetabular dysplasia and anatomical abnormalities of the head and neck of the femur occurred.

3. Results of the experiments suggest that post-natal extension of the hip is of importance in the pathogenesis of congenital dislocation of the hip in man.
