CONGENITAL FIBROSIS OF THE VASTUS INTERMEDIUS MUSCLE

Abstract

1. The cases of six Chinese children affected by so-called congenital fibrosis of the vastus intermedius muscle are described. The reasons for the choice of name are discussed. 2. Reasons for early operation are put forward: in young children simple division of the tendon of the vastus intermedius is adequate. 3. With increasing age severe changes in all the joint tissues occur, notably in the articular cartilage of the patella. These changes are likely to vitiate the result after operation. 4. The importance of getting as much flexion as possible in children of Asiatic race is stressed.
