Outcomes of total hip arthroplasty, as a salvage procedure, following failed internal fixation of intracapsular fractures of the femoral neck: a systematic review and meta-analysis.

AIMS: The optimal management of intracapsular fractures of the femoral neck in independently mobile patients remains open to debate. Successful fixation obviates the limitations of arthroplasty for this group of patients. However, with fixation failure rates as high as 30%, the outcome of revision surgery to salvage total hip arthroplasty (THA) must be considered. We carried out a systematic review to compare the outcomes of salvage THA and primary THA for intracapsular fractures of the femoral neck. PATIENTS AND METHODS: We performed a Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) compliant systematic review, using the PubMed, EMBASE and Cochrane libraries databases. A meta-analysis was performed where possible, and a narrative synthesis when a meta-analysis was not possible. RESULTS: Our analyses revealed a significantly increased risk of complications including deep infection, early dislocation and peri-prosthetic fracture with salvage THA when compared with primary THA for an intracapsular fracture of the femoral neck (overall risk ratio of 3.15). Functional outcomes assessment using EuroQoL (EQ)-5D were not significantly different (p = 0.3). CONCLUSION: Salvage THA carries a significantly higher risk of complications than primary THA for intracapsular fractured neck of femur. Current literature is still lacking well designed studies to provide a full answer to the question. TAKE HOME MESSAGE: Salvage THA is associated with more complications than primary THA for intracapsular neck of femur fractures

Peddinghaus Beam Elevator

Presentation location: Reed Hall of Science Room 330 The focus of this project will be designing an elevator system that can lift & lower structural steel shapes as appropriate between different passline levels. The device will have to integrate with Peddinghaus transfers, and would ideally integrate with a Peddinghaus conveyor line. The device would lift the piece of steel off of a conveyor/transfer, lift it to the appropriate height, and set it down on the machine with the higher passline. The device will require two movements – up/down movement, and onto/off the second transfer/conveyor system. The team will deliver a detailed design for a beam elevator system, with FEA results for any critical lifting components, as well as a scaled proof of concept prototype that provides sufficient detail to prove the functionality of the desig
