Fractures of the femoral neck are common and associated with increased need for institutional care and higher mortality. Optimizing the treatment of these fractures can reduce both human suffering and healthcare costs. The purpose of this study is to investigate the osteointegration of femoral neck fractures following surgical treatment. We examine this using a novel micro-motion analysis computed tomography (CTMA) technique. The study is divided into three parts: 1. In Part I, we validate the CTMA method for assessing the healing of femoral neck fractures using a phantom model. 2. Part II is a prospective study in which we monitor fracture healing with CTMA imaging and study the relationship between micro-motion at the fracture site, patient mobilization, and patient reported outcomes. 3. In Part III, we gather a larger, randomized blinded patient cohort and half of the patients receive romosozumab osteoporosis medication. We then evaluate medication's effect on fracture healing.
