Summary

Reoperation for periprosthetic distal femur fractures occurred in 8.3% of patients to promote union, with higher BMI and more distal screws being risk factors. Deep surgical-site infection reoperation occurred in 4.8% of cases.

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Biomechanics

Background:

  • Periprosthetic distal femur fractures pose significant challenges for achieving union and avoiding infection.
  • Lateral distal femoral locking plates (LDFLPs) are commonly used for fixation, but reoperation rates require investigation.
  • Understanding risk factors for reoperation is crucial for improving patient outcomes.

Purpose of the Study:

  • To identify risk factors for reoperation to promote union in periprosthetic distal femur fractures treated with LDFLPs.
  • To identify risk factors for reoperation due to deep surgical-site infection (DSSI) in these fractures.
  • To evaluate the influence of patient demographics, injury characteristics, and fixation construct features on reoperation rates.

Main Methods:

  • Multicenter retrospective cohort study involving ten level-I trauma centers.
  • Inclusion of patients with OTA/AO 33A or 33C periprosthetic distal femur fractures treated exclusively with LDFLPs.
  • Exclusion of patients with pathologic fractures or insufficient follow-up; analysis focused on fixation constructs using only LDFLPs.

Main Results:

  • An 8.3% rate of unplanned reoperation to promote union was observed.
  • Predictive factors for reoperation to promote union included higher body mass index (BMI) and increased number of screws in the distal segment.
  • A decreased proportion of locking screws in the proximal segment was also a risk factor, while increased locking screws were protective.

Conclusions:

  • 8.3% of patients required reoperation to promote union after LDFLP fixation for periprosthetic distal femur fractures.
  • Higher BMI and more distal screws increased the risk of reoperation for union, whereas proximal locking screws were protective.
  • A 4.8% reoperation rate for DSSI was noted, with no statistically significant predictive factors identified in this cohort.
