ligament. Therefore, the purpose of this study was to determine the relationship between initial fibular displacement
and medial clear space widening on a gravity stress
radiograph.
Initial Fibular Displacement as a
Predictor of Medial Clear Space
Widening in Weber B Ankle Fractures
Methods: A retrospective review was conducted of all
patients with isolated Weber B ankle fractures with both initial injury radiographs and gravity stress view from August
1st, 2014 through April 1st, 2016. A total of 17 subjects were
identified, age 42.6±17 years, time to GSV 4.6±5 days. On
the mortise view of injury radiographs, medial clear space
(MCS), superior clear space (SCS), lateral fibular displacement (LFDP) and fibular shortening (FS) were measured,
and on the lateral view, anterior to posterior fibular gap (A to
P FG) was measured. The gravity stress view was used to
measure the medial clear space widening (MCS-W). All statistical analysis was performed using Stata (College Station,
TX). T-tests were used to calculate mean and standard deviation of each group, correlation and linear regression analyses
were run with each displacement variable relative to MCSW. ROC analysis was used to determine sensitivity and specificity of the displacement variables.

Introduction/Purpose: The diagnosis of medial ankle instability in Weber B ankle fractures remains controversial.
Manual stress radiographs are considered by many to be the
gold standard to assess deltoid ligament integrity (Tornetta
2000). Gravity stress examinations have been shown to be
equivalent (Gill 2007, Schock 2007), and also offer the
advantage of causing less patient discomfort (Schock 2007).
Significant fibular displacement likely serves as a surrogate
for the large amount of energy required to tear the deltoid

Results: Strong significant correlations with MCS-W were
found for LFDP (0.69, p=0.003), and A to P FG (0.72, p=0.001),
but not with FS (0.34,p=0.18). Linear regression analysis
