Total hip replacement with an uncemented Wagner cone stem for patients with congenital hip dysplasia.

Abstract

PURPOSE:

The purpose of this study was to review retrospectively the cases operated upon in our department in recent years with a Wagner stem and a small socket in cases of Crowe I or II dysplastic hips.

METHODS:

We conducted a retrospective clinical radiological review of 30 hips diagnosed with hip dysplasia Crowe I or II treated in our centre between 2002 and 2008. All of them were treated with a Wagner cone stem and a small Trilogy acetabulum (Zimmer ®).

RESULTS:

There were 15 men and 11 women with 13 left and 17 right femurs. Mean follow-up was 43.44 months (range 14-87). Eight patients were Crowe I type and 22 were Crowe II type. Merlé d'Aubigne score pre-operatively was 12.23 and at the last follow-up was 15.54. Mean leg length inequality was 1.79 and after surgery it was 0.69 cm. Complications included three infection and three dislocations (two of them in the same patient).

CONCLUSIONS:

The use of a Wagner stem is a good option to correct the different deformities in the proximal femur in these cases. A small socket allows a correct relocation of the acetabulum in a dysplastic socket with good bone coverage.
