Abstract

Background: Bleeding
from proximal screw drill-site in femoral neck fractures may have the ability
to predict the occurance of avascular necrosis of femoural head. In this study
the relationship of bleeding from proximal screw drill-site during internal
fixation of femoral neck fractures with rate of avascular necrosis was studied. Methods:
This study is a cross-sectional study that was carried out on 19 to 60 year
patients with femoral neck fracture that referred to health care centers in
Rasht, Iran during the year 2008. The age, sex, type of fracture based on
Garden Category were recorded. Then, presence or absence of bleeding from the
proximal screw holes within the first 5 minutes was recorded. Results: In
this study, 40 patients were enrolled with mean age of 39.78±14.4. Twenty two
patients (55%) had bleeding from the proximal end of the screw, and 18 (45%)
did not have any bleeding. Bleeding from proximal screw hole in patients
without avascular necrosis was seen in 11 cases (61.1%). This difference was
statistically significant (p < /i>=.005). Conclusions: Presence of bleeding from proximal screw
hole in femoral neck fracture reduces odds of AVN in femoral head fracture and
can help deciding between internal fixation or arthroplasty for treatment of
such a fracture.
