Formations behind the lateral ankle

Lateral ankle

Boundary laterally	superior and inferior retinaculum of the fibular muscles
Bordered dorsally	tuber calcanei
Bordered ventrally	malleolus lateralis
Contents	v. saphena parva, n. suralis, tendons of m. fibularis longus et brevis
aid	SAPASUFI

The space behind the lateral ankle is bounded by the retinaculum musculorum fibularium superius et inferius (laterally), malleolus lateralis (ventrally) and tuber calcanei (dorsally). The saphena parva vein and suralis nerve pass superficially through both retinacula, and the fibularis longus et brevis tendon in the common tendon sheath runs deep below the retinacula.

For easy memorization, the mnemonic tool SAPASUFI is used – vena SA phena PA rva, nervus SU ralis and tendons musculus FI bularis longus et brevis.
