- Superior extensor retinaculum (partially removed)
- Peroneus tertius muscle
- Extensor digitorum longus muscle (tendons exposed deep to retinaculum)
- Peroneus tertius muscle (tendon of insertion exposed deep to retinaculum)
- Tibialis anterior muscle (tendon covered by retinaculum)
- Inferior extensor retinaculum (divided and reflected)
- Tendinous sheath (opened above level of upper pointer)
- Extensor hallucis brevis muscle
- Fascia of dorsalis pedis
- Lesser saphenous vein
- Superior peroneal retinaculum
- Anterior lateral malleolar artery
- Dorsal lateral cutaneous nerve
