- Discussion:
- allows acces to ankle joint, talus, & other tarsal bones and joints;
- it does not allow access to the navicular and 2nd and 1st cuniforms;
- avoids all of the important vessels and nerves;
- dissection procedes between the
peroneus tertius (deep
peroneal nerve) and the
peroneus brevis (superficial peroneal nerve);
- Incision:
- begin the incision over anterolateral aspect of the leg, medial to fibula
and 5 cm proximal to the ankle joint;
- continue incision distally to cross over talus, calcaneocuboid joint;
- end incision at the base of 4th metatarsal;
- dissection usually divides anterolateral malleolar & lateral tarsal arteries;
- identify & protect intermediate dorsal cutaneous branch of the superficial
peroneal nerve;
- divide origin of
EDB and reflect it distally;
- retract the extensor tendons, the
dorsalis pedis artery, and the deep peroneal nerve
medially, and incise the capsule;
