Question Mechanism of pain in Homans sign

Hi

I know Homans sign for checking DVT is looked down upon these days, since it's risky and has been superseded by better testing modalities. However, I am interested in knowing what exactly is the mechanism responsible for causing pain when the knee of a patient is flexed and the foot is flexed dorsally (the procedure for eliciting Homans sign).

Thank you.

The mechanism thought to be at work in Homans’ sign is that of flexion of the knee with concomitant forced dorsiflexion of the ankle exerting traction on the posterior tibial vein, causing pain
