The Lateral Collateral Ligamentous complex (LCL) is an important
stabiliser of the elbow. It has a Y-shaped structure with three components. In
this study, we sought to describe the ultrasound aspect of the individual
components of this ligamentous complex and to evaluate the performance of
ultrasound in both cadavers and in normal subjects.
Ten cadaveric elbow specimens underwent high-frequency ultrasound. Two
specimens were sliced and two were dissected for anatomical correlation. Ten
elbows of normal subjects were also evaluated by ultrasound. The findings were
The three components of the LCL could be visualised in all specimens and
normal subjects with the exception of the proximal portion of one specimen. In
80% of the specimens and 100% of the healthy volunteers the proximal portion of
the LCL could be separated from the extensor tendons.
High-resolution ultrasound can assess all components of the LCL of
the elbow and can distinguish them from surrounding structures.
