| During the last decades a considerable part (30-65%) of so called idiopathic, primary cases of hip osteoarthritis have been imputed to the presence of non-diagnosed congenital hip disorders, especially hip dysplasia. Hip dysplasia is a congenital disorder, which is mostly seen in girls. |
 |
|
| The disorder results in great nuisances in form of pain and reduced walking distance and osteoarthritis in the hip at a very young age. Until a few years ago, the treatment of osteoarthritis as a result of hip dysplasia was limited to alloplastic treatment. This is not a satisfactory treatment of these young patients who will probably need to have their hip alloplastic revised once or twice in their life. |

|
| If the osteoarthritis is at an early stage it is possible to offer the patients joint preservation surgery (Ganz periacetabular osteotomy), where a chisel is used to disengage the cup which is rotated and fixed with two screws. This improves the mechanical conditions in the joint and normalizes the power and weight transmissions through the joint. |
 |
|
| The Ganz osteotomy can prevent or postpone the development of osteoarthritis in the dysplastic hip and alloplastic treatment can be avoided. The treatment is offered with good results at Aarhus University Hospital and we continuously evaluate the results and do research on how the results can be improved. |
