The supination line is a fictive line along the foot and ankle, on
which over twenty fracture types and approximately ten different ligamentous
sprain-injuries have been identified. OBJECTIVE: The current study was conducted
to evaluate the incidence of different types of supination line injuries visible
at the initial radiographs at the Emergency Department and to determine the type
and percentage of misdiagnosed injuries. METHOD:
Retrospective study of
consecutive patients who visited the Emergency Department, between January 1 and
June 30, 2009, after sustaining an injury of the foot or ankle and had a
radiograph taken within 24h of the incident. RESULTS: In the 6-month study period
1284 patients were included. In these cases the trauma mechanism was a sprain in
780 patients (60.7%). Of these patients 310 suffered from a fracture (40%). There
were 36 (4.6%) false-positive cases and in 91 (11.7%) cases the initial diagnosis
was false-negative. The number with a missed fracture expressed as a percentage
of all patients with a fracture was 29.4% (91/310).
CONCLUSION: Detection of
injuries along the supination line remains difficult. This study might aid in
decreasing the number of misdiagnosed injuries, which is of value as these might
negatively affect outcome.
