BIOM20002 Lecture Notes - Lecture 27: Popliteal Fossa, Tarsal Tunnel, Anatomical Terms Of Motion
Document Summary
Iv disc prolapse at l5/s1, irritation s1 nerve root. This leg raise stretches nerve which will exacerbate pain. Note effects: pain, paraesthesia, motor dysfunction, atrophy, loss of reflexes. Sciatic nerve runs down leg and branches to innervate each compartment of leg. Posteriorly it is the tibial nerve supplies all posterior compartment leg muscles. Plantar flexors etc arises at the back of knee (popliteal fossa) enters tarsal tunnel and divides into plantar nerves. Clinical significance - compression of : ti(cid:271)ial (cid:374). i(cid:374) tarsal tu(cid:374)(cid:374)el (cid:894)(cid:858)tarsal tu(cid:374)(cid:374)el sy(cid:374)dro(cid:373)e(cid:859)(cid:895) pla(cid:374)tar (cid:374)(cid:859)s (cid:271)elo(cid:449) (cid:373)edial ar(cid:272)h (cid:894)(cid:858)jogger(cid:859)s foot(cid:859)(cid:895). Comes down and passes around the head of fibula. Branches to superficial fibular nerve - lateral compartment deep fibular nerve - anterior compartment. Clinical significance - compression of: common peroneal n. at lateral knee (cid:858)foot drop(cid:859). e. g. if a plaster is placed on leg too tight, can get palsy due to compression of the peroneal nerve.
