Implant malposition is the primary surgical risk factor, Hamadouche said. Other surgical risk factors that he discussed included reduced offset, leg length discrepancy and using small-diameter femoral heads. These factors can all lead to impingement, which is a leading cause of hip dislocation following THA, he said.
