Background / introduction
The peri-acetabular osteotomy (PAO) is indicated for symptomatic patients with mild to severe developmental dysplasis of the hip with joint conguity and absence of hip osteoarthritis or only mild degenerative changes of the hip jointy. The surgical procedure is a so-called re-directional acetabular osteotomy. The goal of this treatment is reduction of symptoms in the short term and reduction in occurence of or a delay in onset of secondary hip osteoarthritis. A total hip arthroplasty as subsequent treamtent can be indicated at a older age, thereby leading to a improved survival of the prosthesis.
It is an demanding surgical procedure for the patient with a 6-9 months rehabilitation, and the surgical procedure itself has a long learning curve for its complexity. In the Netherlands, the vast majority of this procedure is performed in the Wilhelmina Hospital Assen with around 1000 surgical procedures in 10 years in the Wilhelmina Ziekenhuis Assen with a 25 years history.
Research question / problem definition
Aim of this study is to collect the basic characteristics of the surgically treated patients in our population for a time period of 5 years. With these characteristics patient categories can be defined and results can be further analysed.
Workplan
A retrospective database study in which all relevant characteristics will be centrally collected including radiologic findings pre- and postoperative, including the most recent follow-up or endpoint as in total hip arthroplasty.
