Zusammenfassung
Studienziel: Mit der klinischen Studie sollen mittelfristige Ergebnisse des totalendoprothetischen Hüftgelenksersatzes mit dem modularen System ANCA-Fit® erfasst werden.
Methode: Eswurden 89 konsekutive Patienten nachuntersucht (51 weiblich/38 männlich). Rechte und linke Hüfte wurden in je 48 Fällen operiert, sieben Patienten wurden beidseits operiert; vier weitere Patienten konnten nicht nachuntersucht werden. Das Nachuntersuchungsintervall betrug durchschnittlich vier Jahre (3-6 J.). Das Durchschnittsalterzum OP-Zeitpunkt betrug 63 Jahre (30-84 J.).
Ergebnisse: Postoperativ erreichten die Patienten durchschnittlich einen Score nach Merle-d’Aubigné-Postel von 16 Punkten (9-18 P.). Der Harris-Hip-Score betrug im Schnitt 92 Punkte (58-100 P.). Bei dem radiologisch evaluierten Score nach Engh-Massin wurden im Schnitt 21 Punkte (12-25 P.) erreicht, der Ara-Femoral-Osseointegration-Score betrug durchschnittlich 3,8 Punkte (1-5 P.) und der Ara-Acetabular-Osseointegration-Score 5,98 Punkte (5-6 P.). Die Komplikationsrate betrug insgesamt 9,4%. Ein echtes Implantatversagen wurde mittelfristig bei 5,2% beobachtet.
Schlussfolgerung: Mit dem modularen Hüftendoprothesen-System ANCA-Fit lassen sich mittelfristig gute klinische Ergebnisse und eine sichere Osseointegration erreichen.
Summary
Aim: In a clinical trial intermediate term results after hipjoint alloarthroplasty with the modular system ANCA-Fit®. were explored.
Method: 89 consecutive patients (51 female/38 male) were examined after four years (3-6 y). Right and left hip joints were operated on in 48 cases each, seven patients hadan alloarthroplastyon both sides; anotherfour patients dropped out. The average age at thetime of operation was 63 years (30-84 y).
Results: Postoperatively the MDA-global assessment averaged 16 points/“good” (9-18 p), the HHS averaged 92 points/“good” (58-100 p). The radiological Engh-Massin global assessment reached 21 points/“ingrowth confirmed” 12-25 p), the ARA femoral global assessment 3.8 points/“good” (1-5 p) and the ARA acetabular global assessment 5.98 points/“excellent” (5-6 p). Complications occured overall in nine percent of our patients, in five percent they were caused bymechanical problems oftheendo- prosthesis.
Conclusion: With the modular system ANCA-Fit® for total hip replacement within intermediateterms good clinical results and confirmed osseointegration are found.
