Endoprosthetic Replacement for Pathological Fractures of the Hip: A 35-year Update

April 13, 2026 updated by: Memorial Sloan Kettering Cancer Center
This study will be based on a retrospective review of patients who received endoprosthetic reconstruction for pathologic fracture of the proximal femur. The objectives would be two-fold: (1) to compare rates ofambulation, pain, and survival to the historic cohort and (2) to identify predictors of ambulation in the current population.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Participants who received endoprosthetic reconstruction
Participants have received endoprosthetic reconstruction for pathologic fracture of the proximal femur.
Other: Data Collection and Analysis
Patient data will be analyzed to ensure that all data fields are available and that suitable sample size is available to answer the research objectives. The rate of ambulation at discharge, ambulation at 3 month follow up (if available), time to death, and pain score between the historic cohort with a current cohort of patients will be compared.
