Prevention study for Periacetabular Tumor
Official title A Randomized Controlled Study Evaluating Modified Cup Anteversion Placement in Prevention of Postoperative Dislocation in Patients Undergoing Acetabular Tumor Resection and Reconstruction
ClinicalTrials.gov ID: NCT05593146
What this study is testing
- What it's testing
- The purpose of this clinical study is to investigate whether patients who receive modified anteversion angle (( α-15°)±10°) of the acetabular cup have a lower risk of dislocation within one year after surgery, compared to patients who receive conventional anteversion angle ( α±10°) of the acetabular cup. The hypothesis is that patients with placement of the modified (( α-15°)±10°) anteversion angle of the acetabular component will have decreased risk of dislocation 1 year after surgery compared to patients with conventional anteversion angle ( α±10°) placement.
