[Durom™ hip resurfacing. Short- to midterm clinical and radiological outcome].
BACKGROUND
Modern hip resurfacing as an alternative for stemmed total hip replacement therapy is associated with a specific risk profile. The aim of this study was therefore to assess the short- to midterm clinical and radiological outcome after introduction of the Durom™ Hip Resurfacing prosthesis in a consecutive series.


METHODS
A total of 132 hips (119 patients, 34 female, mean age 48±8,3 years) were evaluated functionally (Harris Hip Score, UCLA and Tegner activity scores) and radiologically with a mean follow-up period of 29 (6-60) months. Furthermore, preoperative ASA- and Charnley-scores, perioperative parameters as well as complications were registered.


RESULTS
During the observation period the Harris Hip Score improved by a mean of 36.6 points to 92.5±11.6 points (p<0.01). ULCA and Tegner scores improved by a mean of 3.1 and 1.6 to 7.1 and 4.0 points, respectively. Three patients (2.3%) needed revision surgery due to periprosthetic fracture, prosthesis infection, and aseptic loosening of the femoral component. In four patients (3.1%) an initial migration of the acetabular component not requiring surgical revision was observed radiologically.


CONCLUSIONS
The Durom™ Hip Resurfacing prosthesis demonstrated a low revision rate and a good mid-term functional and radiological outcome. Due to acetabular cup migrations in a small number of patients we now use an implant with modified surface design.
