Conditions
Brief summary
MRI computer navigation aims to improve the acetabular cup placement of the prosthesis in the pelvis. This will influence the risk of complications and survivorship of the implant. Current free hand technique leads to an excessive high percentage of position outside the standardised safe zone. The study is to investigate the position of prosthesis of acetabular cup with the MRI based navigation.
Interventions
Navigation of hip joint replacement based on MRI preop findings. Follow up results with CT scan
A standard MRI scan of the hip was used preoperatively to investigate the patient's hip anatomy in order to design the navigation tool specific to each patient. This takes approximately 30 minutes over one day. One scan is required before the operation for each patient.
A CT scan of the pelvis is obtained post-operatively to assess the position of the acetabular component and this is to be compared be

A CT scan of the pelvis is obtained post-operatively to assess the position of the acetabular component and this is to be compared between the MRI navigation group and the standard free hand group. This takes approximately 30 minutes over one day. One scan is required for each patient.
