Total hip replacement for the patient with a dysplastic hip
is difficult. Certain problems that are encountered during total
hip replacement are more pronounced when the hip is completely dislocated.
The classification that we find most practical is that of Hartofilakidis et
al.1. Type-1 hips are those with
dysplasia, in which the femoral head is still within the true acetabulum (Fig. 1Fig. 1). Type-2
hips are those with low dislocation, in which the femoral head is
in a false acetabulum, the inferior lip of which is in contact with
or overlaps the true acetabulum (Fig. 2Fig. 2). Type-3 hips are those with high
dislocation, in which the false acetabulum has no contact with the
true acetabulum (Fig. 3Fig. 3). This classification corresponds with
the Crowe classification2 as follows:
type-1 hips (dysplasia) correspond with Crowe type-I and II hips,
type-2 hips (low dislocation) correspond . . . [Full Text of this Article]
