Hindfoot - lateral approach

* position - supine with sandbag under buttock

* incision
- curved, transverse incsion starting just distal to distal end of lat. malleolus
- continue distally over lat. side of hindfoot & over sinus tarsi
- curve med. to end over talocalcaneonavicular joint

* internervous plane - peroneus tertius (DPN) & peroneal tendons (SPN)

* dissection
- don’t mobilize skin flaps widely — at risk of necrosis
- incise deep fascia in line with skin
- avoid tendons of peroneus tertius & EDL
- retract PT & EDL med.
- detach fat that lies in sinus tarsi
- detach origin of EDB from calcaneus
- expose dorsal capsule of talocalcaneonavicular joint in distal end of wound
- expose dorsal capsule of calcaneocuboid joint lat.
- incise peroneal retinacula & reflect peroneal tendons ant.
- incise capsule of post. talocalcaneal joint
