Sitting or lying supine or lying prone
Ask the patient to roll up long pants and remove shoes and socks.
Lateral to the patient
Please sit. May I touch the side of your leg and foot? (or point to the area)

Guide the patient to sit. With the patient relaxed and with permission, place your fingers on the lateral distal leg and also on the lateral and plantar aspect of the proximal foot. Guide the patient to plantarflex the ankle and evert the foot.
The superior peroneal retinaculum is palpable as the thick fibrous structure that holds the peroneus longus and brevis muscles in place and that is stretched when the these muscles are contracting. It is palpable by using gentle pressure and moving the fingers proximally and distally on the lateral distal leg, superficial to the peroneus longus and brevis muscles.
The inferior peroneal retinaculum is palpable as the thick fibrous structure that also holds the peroneus longus and brevis muscles in place and that is stretched when these muscles are contracting. It is palpable by using gentle pressure and moving the fingers proximally and distally on the proximal aspect of the lateral plantar foot superficial to the peroneus longus and brevis tendons.
