Introduction
Previous research suggested that patients have increased risk of infection with increased
time from presentation with a femoral neck fracture to treatment with a hip hemiarthroplasty
(HHA). The purpose of this study was to determine if rates of prosthetic joint infections within
3 months of surgery was affected by the time from patient presentation with a femoral neck
fracture to the time of treatment with HHA.
Materials and methods
Acute hip fractures treated with HHA between 2005 and 2017 at three centres in Norway
were enrolled in the study. Multi-trauma patients were excluded. Univariable analysis was
performed to determine any significant effect of pre-operative waiting time on infection rate.
Two pre-planned analyses dichotomizing pre-operative waiting time cut-offs were performed.
Results
There were 2300 patients with an average age of 82 (range, 48–100) years included of
which 3.4% experienced a prosthetic joint infection within 3 months. The primary analysis
found no significant difference in infection rate depending on time to surgery (OR = 1.06
(95% CI 0.94–1.20, p = 0.33)). The secondary analyses showed no significant differences in
infection rates when comparing pre-operative waiting time of <24 hours vs �24 hours (OR =
0.92 (95% CI 0.58–1.46, p = 0.73)) and <48 hours vs �48 hours (OR = 1.39 (95% CI 0.81–
2.38, p = 0.23)).
Conclusion
Based off of a large retrospective Norwegian database of hip fractures there did not appear
to be a significant difference in infection rate based on pre-operative wait time to surgery.
