Minimal-invasive periazetabuläre Osteotomie zur Therapie der Hüftdysplasie des Erwachsenen

OBJECTIVE: Performance of a periacetabular osteotomy (PAO) using a minimally invasive approach for three-dimensional correction of the acetabular position. INDICATIONS: Symptomatic developmental dysplasia of the hip in adolescents and adults. CONTRAINDICATIONS: Advanced osteoarthritis of the hip, incongruence of the hip joint surfaces. SURGICAL TECHNIQUE: A periacetabular osteotomy is performed via a minimally invasive approach. RESULTS: In total, 39 patients were followed up for 3.5 (3–4.5) years. The lateral center-edge angle of Wiberg increased significantly from 16.1° (7–24°) to 30.5° (25–37°) (p < 0.0001), the acetabular index changed from 13.2° (2–25.3°) to 2.8° (−3–13°; p < 0.0001). Mean duration of surgery was 88 (57–142) minutes. No major complications occurred.
