Total hip replacement is one of the most frequently performed orthopaedic interventions that can significantly improve the functional status and the quality of life of patients suffering from hip arthrosis. Recently patient satisfaction and patient-reported results of total hip arthroplasty are increasingly emphasised as important tools for the assessments of these interventions. For patients with arthrosis secondary to hip dysplasia, these evaluations can be more difficult, due to younger age and higher functional demands. In this study we compared the Visual Analogue Scale and the Harris Hip Score in order to determine the correlations between these instruments and analyse the possibility of replacing the Harris Score with the Visual Analogue Scale in evaluating the results of hip surgery in patients with dysplastic hips. Our study included 37 women and 4 men (53 hips), with a mean age of 50.96 years (35-58 years), followed for a mean of 4 years postoperatively. Both assessment instruments were used preoperatively and at the follow-up visits. We observed a positive correlation of the values of the Visual Analogue Scale and the Harris Hip Score both preoperatively and postoperatively, with correlation coefficients of +0.71(P <0.001) and +0.77 (P <0.001) respectively. Given these positive correlations, we assumed that the Visual Analogue Scale could replace the Harris Hip Score in the evaluation of patients after total hip replacement. Still it is recommended to combine the Visual Analogue Scale with objective measurements and radiological examination in order to identify significant postoperative changes.

From 1973 to 1991 in a review of S9O cases (1OO%) with
dislocation * of the hip observed, we found 39 breech
presentations at birth (13,5%); among these, IS (4%) cesarean
sections were performed.
Foetal US examination could be useful to study the
dysplastichip development. In fact, this examination has a good
specificity, since it visualizes the whole hip.
Our evaluation was based on more qualitative than
quantitative data, according to Graf's angles. In fact, it is
difficult to obtain a section plane according

) for adequate cement mantle has been allowed. In cases of dysplastichips, the cups have been positioned in the anatomical position of the acetabulum. The cavity in the superior lateral part of the false acetabulum, which should be reproduced intraoperatively, was estimated for bone graft or cement coverage. Templating the femoral component took place as the desired stem was selected from the implant library; modifying the size and position was done till the stem layout adequately fit the femoral canal. Then, different offsets (standard or high) have been compared to
