摘要Background Pelvic fractures are uncommon in elderly patients and so are infrequently addressed in the literature.The purpose of this study was to investigate the management and outcome of pelvic fractures in elderly patients.Methods We retrospectively reviewed the records of pelvic fractures in elderly patients (age ≥55 years) who were treated in our department from September 1997 to May 2010.Results A total of 40 elderly patients with pelvic fractures were identified.Their mean age was 65.8 years (range 55-87 years).About 68％ (n=27) were men.The average Injury Severity Score (ISS) was 17.8 (range 6-45).Twelve (30％)patients required blood transfusion (mean 10 units) during the first 24 hours.The fractures were most frequently due to falling from a standing position (48％).Almost half (48％) were grade I breaks.Associated injuries were present in 70％(n=28) of patients,and 65％ (n=26) had medical co-morbidities.Altogether,29 patients (73％) underwent non-surgical management of their pelvic fracture.The average hospital stay was 25 days.There were five in-hospital deaths and one death 10 months after discharge.High ISSs (＞25) were associated with increased in-hospital mortality (P=0.018).At the final assessment (mean follow-up 15 months),52％ of the surviving patients had experienced decreased self-sufficiency.Conclusions Pelvic fractures in elderly patients result in high morbidity and mortality rates.A high ISS (＞25) can be used to identify a patient at high risk.We recommend aggressive resuscitation and intensive care for that patient.For patients with an unstable pelvic or displaced acetabular fracture (≥2 mm) who can endure surgery,open reduction and internal fixation can provide adequate fixation for early weight-bearing and restoration of the bone stock.
