INTRODUCTION
Prosthetic joint infection is a devastating complication of arthroplasty, ranging from recurrent surgical procedure to mortality.
The rate of prosthetic joint infection is estimated to be 0.5-2 % and the rate is expected to increase with the rise in number of joint replacements.(3)
Displaced neck of femur fracture occurs more in elderly people, women are two times affected more than men.
Elderly people are associated with comorbidities, this increases their risk to acquire prosthetic joint infection.
Diagnosis of PJI require combination of clinical findings and multiple laboratory test.
Our quest was to identify any relative bacteria contamination in acute fracture neck of femur hematoma and it is implications in PJI.

AIM OF THE WORK
The aim of the study was to evaluate if hematoma contamination in acute fracture neck of femur, in the elderly is related with early post-operative joint infection.



PATIENTS AND METHODS
The study was conducted on 40 patients with neck of femur fracture undergoing hip arthroplasty at EL Hadra University Hospital.
Hematoma samples were cultured using conventional cultures and BACT/ALERT.
