Abstract

Background Hip fractures occur frequently in the elderly population over the age of 60 years following low-energy domestic falls. The postoperative mortality after hip fracture surgery depends on numerous factors like comorbidities, pre-fall ambulatory status, nutritional status, cognition, and overall physical health. In this context, the physiological age and reserve play a vital role in mortality after hip fracture surgeries. This physiological reserve is measured in terms of "frailty." There are many frailty indices that assess the physiological reserves of an elderly patient. The modified frailty index (MFI) is one of the validated indexes predicting postoperative complications and mortality. So we concluded there is a need to assess the patients with MFI preoperatively, based on which mortality and postoperative complications could be predicted in our patients.

MATERIALS AND METHODS We included 100 patients aged more than 60 years with intertrochanteric and neck of the femur fractures, who were managed surgically. We followed the patients for one year and observed the immediate and late complications and mortality at the end of one year. To reduce bias, patients with pathological fractures, revision surgeries, contralateral fractures, high-energy trauma, younger than 60 years of age, and previous proximal femur fracture surgery on the side of injury were excluded from the study.

RESULTS The primary objective was to study the correlation between the MFI with one-year mortality. We observe that the MFI score had a significant effect on mortality at one year (p-value = 0.0316). With a unit increase in the MFI score, the odds of death increase by a factor of 1.52.

CONCLUSION There is a strong correlation between MFI with one-year mortality and postoperative complications after hip fracture surgeries in the elderly. This MFI can be used as a preoperative predictive model to predict the mortality and postoperative complications after hip fractures in the elderly. It will also help patients and their caretakers in decision-making and elucidating surgery choices.
