Periacetabular osteotomy reduces the dynamic instability of dysplastic hips.
We compared the dynamic instability of 25 dysplastic hips in 25 patients using triaxial accelerometry before and one year after periacetabular osteotomy. We also evaluated the hips clinically using the Harris hip score and assessed acetabular orientation by radiography before surgery and after one year. The mean overall magnitude of acceleration was significantly reduced from 2.30 m/s(2) (sd 0....
متن کاملEvaluation of Bernese periacetabular osteotomy: prospective studies examining projected load-bearing area, bone density, cartilage thickness and migration.
The typical dysplastic hip joint is characterised by maldirection of the acetabulum and femoral neck, insufficient coverage of the femoral head focally and globally and erosions of the limbus acetabuli (1). An unknown number of persons with hip dysplasia will suffer from pain in hip or groin, decreased hip function and development of osteoarthritis at a young age. The Bernese periacetabular ost...
متن کاملComparison of periacetabular osteotomy and total hip replacement in the same patient: a two- to ten-year follow-up study.
We evaluated 31 patients with bilateral dysplastic hips who had undergone periacetabular osteotomy for early (Tönnis grade 0 or 1) or moderate (Tönnis grade 2) osteoarthritis in one hip and total hip replacement for advanced (Tönnis grade 3) osteoarthritis in the other. At a mean follow-up of 5.5 years (2 to 9) after periacetabular osteotomy and 6.7 years (3 to 10) after total hip replacement, ...
متن کاملPeriacetabular osteotomy: preoperative radiographic predictors of outcome.
Periacetabular osteotomy is an extremely effective treatment for the spherical dysplastic hip without significant secondary osteoarthrosis. Yet, the reliability of the procedure in patients with some degree of secondary osteoarthritis, asphericity, or associated deformities remains undefined. The purpose of the current study was to analyze a group of patients treated by periacetabular osteotomy...
متن کاملThe Bernese periacetabular osteotomy: clinical, radiographic and mechanical 7-15-year follow-up of 26 hips.
BACKGROUND The Bernese periacetabular osteotomy is used in dysplastic hips to increase the load-bearing area of the hip and to prevent osteoarthritis. The aim of our work was to determine the contact hip stress before and after the osteotomy and to compare the relief of stress with the long-term radiographic and clinical outcome. PATIENTS AND METHODS We followed 26 dysplastic hips (26 patient...
