anterior tibial artery
what is relationship of sustentaculum tali to medial tendons
TP- Dorsal and superficial FDL- Immediately superficial FHL- plantar to ST in a bony groove of calcaneus
Tibial nerve is inbetween which tendons supramalleolar
FDL and FHL
Origin of common plantar digital nerves
medial and lateral plantar branch of tibial nerve
What is the significance of some fluid within the sheath of the TP tendon beyond the medial mallelus
usually normal
at navicular no fluid
TP fluid at the navicular
should not be present since tendon sheath is absent
