Austin­ Moore­ hemiprosthesis­ for­ intracapsular ­hip ­fracture: analysis ­of ­mortality, ­infection ­and­ dislocation ­in ­91 ­patients.

Abstract

Abstract Background: Hip fractures are common in elderly people. Hemiarthroplasty is an accepted treatment for intracapsular fractures of the hip in elderly patients with low functional demands. The objective of this study is to show the 30-day and 1-year mortality rates and associated complications in patients with bad performance status. Methods:­ Between 2003 and 2010, 1,134 patients with intracapsular fractures of the hip were treated. One hundred and one patients (9%) were treated with Austin Moore hemiprosthesis and 91 of them were included in this series. All were toddlers in their homes and they had multiple comorbidities. Kaplan-Meier estimator was used to evaluate survival. Mortality was then related to sex, age, infection and dislocation using a Cox proportional hazards regression model. Results:­ Seventy patients were women (77%) and the mean age of the series was 85 years. The 30-day and 1-year mortality rates were 7% and 36%, respectively. Ten patients (11%) had an episode of prosthetic dislocation and 13 (14.3%) had an infectious complication. Infection/mortality and male/mortality associations were statistically significant (p = 0.009 and p = 0.013). Patients who suffered an infection had a higher rate of dislocation (p = 0.00001). Conclusion: Hemiarthroplasty with Austin Moore prosthesis is a good option for patients with displaced intracapsular hip fractures, low activity demand and multiple comorbidities, since it is a quick procedure that eliminates pain, allowing early mobility.
