• OBJECTIVE
    • Periprosthetic femoral fractures (PFF) are a serious complication in patients who have undergone hip arthroplasty. Some authors consider revision arthroplasty as the gold standard in the surgical treatment of Vancouver type B2 and B3 PFF. Others, however, prefer treating PFF by open reduction and internal fixation (ORIF), without revising loose stems, especially in elderly patients. In the present retrospective study, we report mid/long-term results in a series of patients affected by B2 or B3 PFF surgically treated by ORIF, using a locking compression plate (LCP), thus avoiding the need of revision arthroplasty.
  • MATERIALS AND METHODS
    • We reviewed 28 patients affected by B2 or B3 PFF surgically treated between 2010 and 2017 by ORIF using a LCP, after an average follow-up of 5.5 years. The average age of the patients at diagnosis was 78 years; in 17 patients, the femoral stem was uncemented while in 11, cemented. The mean interval time between hip arthroplasty and PFF was 6.7 years. Clinical results were assessed using Harris Hip Score (HHS), while radiographic results according to Beals and Tower criteria.
  • RESULTS
    • At follow-up, HHS ranged from 72 to 96 points; 8 patients had an excellent result, 12 got a good result and 8 a fair result. According to Beals and Tower criteria, all the radiographic results were excellent (9 patients) or good (19 patients). The majority of our patients returned to their previous ambulatory levels.
  • CONCLUSIONS
    • According to our results, in elderly patients affected by Vancouver type B2 or B3 PFF, surgical treatment by ORIF using a locking compression plate, without a stem revision, seems to be associated with satisfactory outcome.
