Ventral trochlear prominence
Updates to Article Attributes
Ventral trochlear prominence describes and measures the bony surplus in the anterior femoral surface at the most superior or proximal aspect of trochlea.
Usage
Ventral trochlear prominence is used for the assessment of trochlear dysplasia, a risk factor for patellofemoral instability 1-4 in in sagittal magnetic resonance images. It can be seen as an analogue to Henri Dejour’s trochlear bump 1-3.
A review about the quality assessment of measurements for trochlear dysplasia identified the ventral trochlear prominanceprominence as one of the more useful measurements 4.
Measurement
The distance between an extension line of the anterior, supratrochlear femoral cortical surface and the most anterior cartilaginous surface of the trochlear groove is measured. The measurement is conducted on a sagittal plane through the trochlear groove 1.
Interpretation
A cut-off value of ≥ 8mm indicates trochlear dysplasia, with a reported sensitivity and specificityofspecificity of 75% and 83% respectively 1.
History and etymology
Ventral trochlear prominence as an assessment tool for trochlear dysplasia in MRI was introduced by CW.Pfirrmnann 1 as an analogue of Henri Dejours trochlear bump 2.
