The aim of this study was to assess the accuracy
of placement of pelvic binders and to determine whether circumferential
compression at the level of the greater trochanters is the best
method of reducing a symphyseal diastasis. Patients were identified by a retrospective review of all pelvic
radiographs performed at a military hospital over a period of 30
months. We analysed any pelvic radiograph on which the buckle of
the pelvic binder was clearly visible. The patients were divided
into groups according to the position of the buckle in relation
to the greater trochanters: high, trochanteric or low. Reduction
of the symphyseal diastasis was measured in a subgroup of patients
with an open-book fracture, which consisted of an injury to the
symphysis and disruption of the posterior pelvic arch (AO/OTA 61-B/C). We identified 172 radiographs with a visible pelvic binder. Five
cases were excluded due to inadequate radiographs. In 83 (50%) the
binder was positioned at the level of the greater trochanters. A
high position was the most common site of inaccurate placement,
occurring in 65 (39%). Seventeen patients were identified as a subgroup
to assess the effect of the position of the binder on reduction
of the diastasis. The mean gap was 2.8 times greater (mean difference
22 mm) in the high group compared with the trochanteric group (p
<
0.01). Application of a pelvic binder above the level of the greater
trochanters is common and is an inadequate method of reducing pelvic
fractures and is likely to delay cardiovascular recovery in these
seriously injured patients.
