Raad et al reported the Pathologic Fracture Mortality Index to evaluate a patient undergoing surgery for a pathologic fracture. The authors are from the Johns Hopkins University.
Patient selection: pathologic fracture, undergoing surgery
Outcome: 30-day mortality
Parameters:
(1) preopreative anemia
(2) serum alkaline phosphatase in IU/L
(3) preopreativeserum albumin in g/dL
(4) pulmonary disease
(5) weight loss over the past 6 months
(6) functional status for activities of daily living
(7) white blood cell count per microliter
