Anterior to the patient.
Please sit. May I touch the front of your leg and ankle? (or point to the area).

Guide the patient to sit. With the patient relaxed and with permission, place your fingers on the anterior distal leg and also on the proximal dorsal foot. Guide the patient to dorsiflex the ankle and while maintaining dorsiflexion, invert and evert the foot.
The superior extensor retinaculum is palpable as the thick fibrous structure that holds the dorsiflexor muscles in place and that is stretched when the dorsiflexor muscles are contracting. It is palpable by using gentle pressure and moving the fingers proximally and distally on the anterior distal leg.
The inferior extensor retinaculum is palpable as the thick fibrous structure that also holds the dorsiflexor muscles in place and that is stretched when the dorsiflexor muscles are contracting. It is palpable by using pressure and moving the fingers proximally and distally on the proximal aspect of the dorsal foot.
