Expert centre of total hip arthroplasty

Our Expert Centre of total hip arthroplasty (Radboud Expertcentrum voor Heupprothesiologie) uses the results of its own research to further develop its surgical techniques. Already in the 1970’s, the development of the impaction bone grafting technique began. Throughout the years, this technique has been further improved. The impaction bone grafting technique has always been used in combination with a cemented cup and stem. In order to evaluate the effect of our treatment, we have always performed extensive clinical follow-up studies to investigate the durability of our technique for specific cohorts of patients. An example of such a cohort are our patients younger than 50 years of age at time of surgery. From 1988 onwards, all patients are included in a database and a radiographic and clinical follow-up of these patients with help of Patient Related Outcome Measurements are performed. On a regular basis, our results are published in international journals and presented at many international conferences.

Revision surgery

In the long run, many patients who have received a total hip arthroplasty (THA) at a younger age, will inevitably face a revision THA due to their long life expectancy. Revision THA’s are always performed in combination with impaction bone grafting. In case of extensive bone defects, we also use impaction bone grafting often combined with a wire mesh to reconstruct the acetabular side. This specific cohort of revision THA patients are closely followed by our department. The outcome of these revision surgeries is important since it determines the possibility of future re-revisions in these difficult THA patients.

Developments

For the development of the impaction bone grafting technique and the improvement of the cementing technique we work in close cooperation with the Orthopedic Research Lab (ORL).
