Fractures: Bone Repair

3.7K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Summary

Distal femur replacement (DFR) for distal femur fractures (DFFs) showed a 5.8% infection rate and 16.6% reoperation rate. While 55% of patients regained baseline function, the one-year mortality was 27%.

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Biomaterials Science

Background:

  • Distal femur fractures (DFFs) are complex injuries, often requiring surgical intervention.
  • Distal femur replacement (DFR) is a treatment option for severe DFFs, particularly in elderly patients with poor bone quality.
  • Outcomes and complication rates of DFR for DFFs require further investigation.

Purpose of the Study:

  • To evaluate the outcomes of distal femur replacement (DFR) in patients with distal femur fractures (DFFs).
  • To estimate the incidence of periprosthetic joint infection (PJI), reoperation, mortality, and functional recovery after DFR for DFFs.
  • To compare outcomes between native and periprosthetic DFFs treated with DFR.

Main Methods:

  • Retrospective cohort study including 173 adult patients from 12 US academic trauma centers (2010-2022).
  • Patients underwent DFR for native or periprosthetic DFFs (OTA/AO 33A1.1 - 33C3.3).
  • Primary outcome was PJI; secondary outcomes included reoperation, one-year mortality, and function, analyzed using Kaplan-Meier curves and Fisher's exact testing.

Main Results:

  • The overall PJI rate was 5.8% (95% C.I., 3.1-10.5%), with 2.3% for native DFF and 6.9% for periprosthetic DFF.
  • The reoperation rate was 16.6% (95% C.I., 11.7-23.0%), and one-year mortality was 27% (95% C.I., 20-35%).
  • Fifty-five percent of patients returned to their baseline function (95% C.I., 46.9-62.1%).

Conclusions:

  • DFR for native and periprosthetic DFF is associated with a 5.8% PJI rate, 16.6% reoperation rate, and 27.0% one-year mortality.
  • DFR can be a viable option for complex DFFs, but patient counseling regarding significant risks is crucial.
  • Functional recovery was observed in 55% of patients, highlighting the need for careful patient selection and management.
