Superficial Poserior Compartment

Deep Posterior Compartment
- Anatomy:
- lateral compartment contains only 2 muscles,
peroneus brevis, &
longus,
which serve primarily as plantarflexors and evertors of foot;
- superficial
peroneal nerve runs in septum between peronei &
EDL;
- this nerve is rarely injured w/ closed frxs of fibular shaft, but is at risk with
frxs of fibular neck, traction injuries of lower extremity (because of its
relatively fixed position proximally at fibular neck), or frx at junction of
middle & distal thirds of the leg, where subQ superficial sensory branch
lies between
peroneus brevis and
extensor digitorum longus msucles;
- pin insertion for either skeletal traction or external fixation must avoid penetration or compression
of common
peroneal nerve proximally at the fibula;
- extra padding and avoidance of pressure indentations over proximal fibula will help prevent
the development of the peroneal palsy;
- compartment syndromes are much less common in lateral compartment than in the
anterior compartment;
Tendon injuries about the ankle resulting from skiing.
Operative anatomy of nerves encountered in the lateral approach to the distal part of the fibula.
