Incidence of periprosthetic fractures after hip hemiarthroplasty: Are uncemented prostheses unsafe?

摘要: Abstract Displaced intracapsular fractures of the neck femur are routinely treated in elderly with either cemented or uncemented hemiarthroplasty. Recent evidence suggests a superior outcome use cement, but prostheses still employed for those multiple co-morbidities particular frailty. In Scotland, Scottish Intercollegiate Guidelines Network (SIGN) recommendations used to identify which patients should receive prosthesis. These simply based upon presence cardiorespiratory disease, particularly frail patient. Between January 2007 and June 2010, total 1397 neck-of-femur presented our unit. Retrospective analysis was performed attention given rate postoperative periprosthetic fracture. As many as 546 were hemiarthroplasty, 183 Exeter Trauma Stem (ETS) 363 an Austin-Moore prosthesis (AMP). At time retrospective analysis, we found that 15 (4%) went on sustain There no group ( p =0.004). Data by case-note review sustaining fracture then performed. Seven (50%) suffered from confusion secondary dementia, six (43%) had history significant cardiac disease (recent myocardial infarction (MI) failure) two (14%) known renal impairment. The mean after hemiarthroplasty 2 years. majority (80%) required further surgery. Revision surgery these associated overall complication 42% (mainly deep infection haemorrhage requiring transfusion). Two could be conservatively. It is concluded that, conjunction treating senior anaesthetist, implants considered all patients, especially who deemed co-morbidities. A 14% at years represents potentially unacceptable risk such population. particular, feel AMP not displaced fractures.
