Detaljeret beskrivelse
Background: The Acetabular Cup Orientation Guide(ACOG) System from MATERIALISE NV was developed and is intended to be used as a surgical instrument to assist in the positioning of acetabular cup components intra-operatively using anatomical landmarks of the pelvis that are clearly identifiable on preoperative computed tomography (CT) imaging scans.
Use of ACOG is a relative new technique. ACOG, based on CT imaging data, fit directly into the patient's anatomy and enable primary total hip replacement . Data showing extra benefit of this technique compared to conventional THR technique are not widely available.
Aim: To determine the safety of this new surgical technique compared to conventional THR.
Methods: 30 participants will be randomized to 2 groups. One group will be operated for a THR with the conventional technique and the other group will be operated for a THR with the assistance of the ACOG System. CT imaging will be taken pre and post operatively to measure cup orientation.
