The matching rate effects blood loss in PFNA II treating femoral intertrochanteric fracture
Renjie Xu
Suzhou Municipal Hospital, China
Objective:
The objective of this study is to investigate the effect
of the ratios of marrow cavity diameter and intramedullary nail
diameter fromdifferent layers on hidden blood loss, overt blood
loss and total blood loss in the perioperative period during using
PFNA II for femoral intertrochanteric fracture.
Methods:
We retrospectively studied 70 patients treated in
our hospital from January 2015 to November 2016. Their age,
gender, height, fracture type, preoperative and postoperative
HTC, and overt blood loss during operation were analyzed. Total
blood loss and hidden blood loss were calculated using CROSS
equation. According to post-operative X-ray results, the ratios
of marrow cavity diameter and intramedullary nail diameter
from different layers, start of funnel, end of funnel and femoral
isthmus, were measured, the mean of the ratio from frontal
and lateral X-ray were designated as R. We classified the data
into a high matching group (R is less than the median) and a
low matching group (R is greater than or equal to the median)
within each layer, and compared total blood loss, hidden blood
loss and overt blood loss between the two groups. Hidden
blood loss, as dependent variable, and age, fracture type and R,
as independent variables were analyzed by usingmultiple linear
regression.
Results:
The hidden blood loss and total blood loss in the high
matching group were significantly less than that in the low
matching group on three layers (P<0.05), however, there was
no significant difference of overt blood loss. Only R values from
start of funnel and end of funnel were correlated to hidden
blood loss (P<0.05).
Conclusion:
The higher matching rate of PFNA II at the funnel is
the less hidden blood loss and total blood loss will be.
