Evaluation and Management of Failed Hemiarthroplasty.

Hemiarthroplasty is a common procedure for treatment of displaced femoral neck fractures in low-demand patients. As hip fracture incidence continues to increase, the need for revision hemiarthroplasty is also expected to increase. Multiple etiologies can result in a failed hemiarthroplasty, including persistent pain, infection, instability, leg-length discrepancy, and trauma.
