“…Delimar et al [22] developed a new reconstruction method using a pedicle iliac graft after verifying that the deep circumflex artery was long enough to transfer this graft without resorting to micro-vascular anastomosis. Rozkydal et al [23] reported 43 cases of dysplastic hips treated with a CLS Expansion shell and a structural femoral head autograft. These options may be of interest when there is deficient acetabular bone stock in order to place the socket in its anatomical centre of hip rotation.…”

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.

“…21 In some studies it had been assumed that Crowe types I and II correspond to Hartofilakidis type I, Crowe type III to Hartofilakidis type II and Crowe type IV to Hartofilakidis type III. 22,23 This assumption is not always valid because the anatomy of the acetabulum is variable and the amount of migration is not a definite criterion by which to judge the type of dysplasia.…”

Our study evaluated the reliability of the Crowe and Hartofilakidis classification systems for developmental dysplasia of the hip in adults. The anteroposterior radiographs of the pelvis of 145 patients with 209 osteoarthritic hips were examined twice by three experienced hip surgeons from three European countries and the abnormal hips were rated using both classifications. The inter- and intra-observer agreement was calculated. Interobserver reliability was evaluated using weighted and unweighted kappa coefficients and for the Crowe classification, among the three pairs there was a minimum kappa coefficient with linear weighting of 0.90 for observers A and C and a maximum kappa coefficient of 0.92 for observers B and C. For the Hartofilakidis classification, the minimum kappa value was 0.85 for observers A and B, and the maximum value was 0.93 for observers B and C. With regard to intra-observer reliability, the kappa coefficients with linear weighting between the two evaluations of the same observer ranged between 0.86 and 0.95 for the Crowe classification and between 0.80 and 0.93 for the Hartofilakidis classification. The reliability of both systems was substantial to almost perfect both for serial measurements by individual readers and between different readers, although the information offered was dissimilar.

“…In two previous reports, the 10-year survival of acetabular components other than the CLS expansion cup used in metal-on-metal bearings ranged from 94 to 96% with revision for any reason and 95 to 99% with revision for aseptic loosening as the end point [26,27]. The 10-year survival of the CLS expansion cup disregarding the bearing couple with revision for any reason ranged from 92.7 to 100% in three different studies [34][35][36]. This raises the question whether the CLS expansion cup performs inferiorly in Metasul-based metal-on-metal THR.…”
