Long–term outcome after hip fractures treated with hip arthroplasty – from an orthopaedic and patient’s perspective

Projekt: Avhandling



Femoral neck fracture is one of the major types of hip fractures. Any kind of conventional hip arthroplasty is used as primary fracture treatment. Hemiarthroplasty (HA), in which only the femoral side of the joint is exchanged, is predominant. A large solid metal head (“unipolar head”) articulate directly with the native acetabulum, thus risking erosion of the cartilage. In order to reduce this risk, a “bipolar head” was developed in the 1970s. It consists of an inner and an outer articulation, in both of which motion can occur. There is only weak evidence that bipolar heads decreases the risk of erosion.However there are conflicting results, and clinical eqoipose exists whether a bipolar or unipolar should be used.Research will be conducted with close collaboration with Swedish arthroplasty register. Aims:To investigate longterm consecvenses of sustaining a femoral neck fracture treated with hemiarthroplasty. With the patient in focus.  Who survive long after their fracture. Is there anything we as surgeons can do to improve outcome when we choose the implant? With focus on patients treated with hemiarthroplasty. Any differences in reoperationrate and functional outcome depending on design of both the metallic head and stem?
