Biomechanical evaluation of hip joint after Salter innominate osteotomy: a long-term follow-up study

Popis výsledku v původním jazyce

The biomechanical state of the hip after a Salter innominate osteotomy was investigated by using the radiographic data of 38 operated and 21 contralateral nonoperated hips from our archives. The centre-edge angle of Wiberg was determined from the radiographs taken shortly after the operation. From the radiographs of the latest follow-up (7-13 years after the operation), we also determined the peak value of contact hip joint stress normalized by the body weight, and the functional angle of the weight-bearing area. A mathematical model was used. We show that the geometrical parameters aside from the centre-edge angle may considerably influence the contact hip stress distribution. We also show that the functional angle of the weight-bearing area is a morerelevant parameter than the normalized peak stress if the exact magnification of the images is not known and if there is considerable variation of the image size within the sample.
