Clinical Study On Bernese Periacetabular Osteotomy For The Treatment Of Adult Acetabular Dysplasia

Objective:To probe into the Bemese osteotomy for the treatment of congenital acetabular dysplasia.Methods:From April 1998 to December 2001,29 patients(30 hip)with acetabular dysplasia were operated upon with Bernese osteotomies.The ages of the patients ranged from 14 to 35 years.The mean D'Aubigne hip score was 13(6 ~ 15)pre-operatively.Average CE angle was -0.1(-5~20),Sharp angle was 50(42~ 60);ACM angle was 57.5 (52 ~65 ).Results:D'Aubigne hip score increased to 17(12.5-18) post-operatively.CE angle increased to 40(28~50);Sharp angle was improved to 36(25~38),and ACM angle was improved to 35 (23 ~45 ).The hip ROM decreased in all directions.The complications include:one case of deep vein thrombosis,2 incision liquefaction,2 lateral cutaneous nerve dysfunction,and excessive lateral displacement occurred in one case.Conclusion;The Bernese osteotomy has the advantages that are beyond compare with other osteotomies.So it is the best to choose Bernese osteotomy for the treatment of teenaged or adult acetabular dysplasia.
