Research proposal abstract
In total hip arthroplasty (THA), optimal component placement of the acetabular and femoral component as well as correct sizing are thought to decrease wear, optimize function and enhance implant-survival. In addition, the presence of limb length differences of large offset changes may negatively influence patient satisfaction. However, achieving appropriate limb length and offset in THA can be challenging. According to some studies, intraoperative fluoroscopy during THA would enhance acetabular component positioning or limb-length disparity compared to no fluoroscopy in patients operated via direct anterior approach in supine position. Factual information of quality of care, trends over time and possible differences in patient population and subsequent outcome between intra-operative fluoroscopy (IOF) and conventional surgery is lacking.
In this study we aim to determine:
(1) the frequency of intra-operative fluoroscopy usage in primary THA in the Netherlands; we will describe the trend over time and the distribution of surgical approaches among THA patients operated with IOF.
(2) The risk of revision after primary THA after IOF compared to conventional (non-IOF) using data from the Dutch Arthroplasty Register (LROI).
(3) The differences in reasons for revision for patients operated with and without IOF.
