Modified minimally invasive direct anterior approach through a bikini incision for total hip arthroplasty: technique and results in young female patients

Direct anterior approach for THA has gained popularity over the last years. However, concerns have been raised regarding the cosmetic, related to the incision that does not respect the Langer’s skin tension line and may produce hypertrophic scars. The aim of this study was to analyze the preliminary results in 22 young female patients undergoing THA through a minimally invasive direct anterior approach using a modified oblique bikini incision. Clinical evaluations showed an improvement of WOMAC, UCLA and Harris Hip Score at 5-month follow-up. The technique ensured proper implant positioning and showed advantages in terms of complications, transfusion rates, hospital length of stay and functional recovery. From the aesthetic point of view, the expected cosmetic results were obtained. Minimally invasive direct anterior approach using a modified oblique bikini incision represent a viable option for THA, combining both the advantages of a minimal invasive procedure with a better aesthetic appearance.
