Tibial Nerve
How many layers of the foot
4 Muscular Arches
Where do vessels and nerves travel in the foot
Between 1st and 2nd layer ie relatively superficial
Weber C injury
Fracture above the syndesmosis, meaning syndesomis effected = serious as this is a key ligament in stabilising the tib and fib
Lis Franc Injury associated with
Falling
Lis Franc Injury Complication
Fracture / dislocation fo 2nd Tarsometatarsal
Why is Lis Franc Injury serious
Dorsalis Pedis passes right near the 2nd Tarsometatarsal = can be involved
