Preoperative clinical, radiographic, and laboratory assessments are critical in determining the etiology of a painful hemiarthroplasty before conversion to a total hip arthroplasty.
Preoperative evaluation is critical to determine the etiology of failed hemiarthroplasty before converting to a total hip arthroplasty.
Thorough preoperative evaluation may optimize revision planning for failed hemiarthroplasty; leaves open need for prospective data to refine protocols.
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. Preoperative clinical, radiographic, and laboratory assessments are critical in determining the etiology of the painful hemiarthroplasty. The standard of care for surgical management of failed hemiarthroplasty is conversion to a total hip arthroplasty. However, establishing the etiology preoperatively is essential to planning before treating the failed hemiarthroplasty.

Sheth et al. (2018) conducted a review in Failed hemiarthroplasty. Conversion to total hip arthroplasty was evaluated. Preoperative clinical, radiographic, and laboratory assessments are critical in determining the etiology of a painful hemiarthroplasty before conversion to a total hip arthroplasty.
