Abstract |
Introduction |
Osteosynthesis of peritrochanteric fractures by intramedullary nail is associated with a 3 to 15% rate of complications requiring revision surgery. The objective of our study was to compare mortality and autonomy between patients who required revision surgery after osteosynthesis, and patients without revision surgery.
Hypotheses |
Patients who underwent revision surgery after osteosynthesis of a peritrochanteric fracture by intramedullary nail did not exhibit excess mortality or loss of autonomy compared to those who did not undergo revision surgery.
Methods |
Between January 2017 and October 2019, 312 consecutive patients were operated on for a peritrochanteric fracture by intramedullary nail. Among them, 23 patients (7.4%) required revision surgery (change, nail removal, total hip arthroplasty). Mortality at 90 days and at one year was evaluated and compared between the group of “revision” patients and “no revision” patients. The level of autonomy was assessed by the Parker and Palmer score, one year postoperatively and compared between the 2 groups.
Results |
The patients requiring revision surgery were younger: 73 years old vs. 86 years old (p<0.011). The overall mortality was 7.25% at 90 days after surgery and 15% at one year. Mortality was zero at 90 days, and at 1 year, postoperatively for patients requiring revision surgery. There was no significant difference for the mortality at 90 days (p=0.39) between the 2 groups, however at 1 year, it was significantly less for the revision patients (0% vs. 17%, p=0.032). There was no significant difference for the Parker score between the “revision” group; 5 (4–9) and the “no revision” group; 4 (3–7), at one year postoperatively (p=0.24).
Conclusion |
This study did not show any excess mortality, nor loss of autonomy at 1 year postoperatively, for patients who required osteosynthesis for a trochanteric fracture, and who presented with a complication requiring revision surgery.
Level of evidence |
III, comparative retrospective study.
