title: Hip abductor defect repair by means of a vastus lateralis muscle shift.
abstract: Scarring or detachment of the hip abductors, particularly of the gluteus medius, from their insertion may lead to severe abductor weakness, recurrent dislocations, pain, and diminished quality of life. We performed a retrospective study to evaluate whether vastus lateralis shift is associated with satisfactory results and low rate of complications. Eleven adults underwent vastus lateralis shift to bridge a well-documented abductor muscles' insertion defect. Preoperative and postoperative hip functions were assessed applying the Merle d'Aubigne score, British Medical Council scale, and Visual Analog Scale. Significant postoperative improvement was noted in mean Merle d'Aubigne score, gluteus medius muscle force, and quality of life. Vastus lateralis shift represents a viable treatment option for hip abductor deficiency, significantly improving abductor strength and overall quality of life.
