Common peroneal neuropathy — where the injury involves the common peroneal nerve itself, rather than a more distal branch — presents with a distinct clinical pattern that shapes both the bracing strategy and the surgical pathway when conservative management is insufficient.

Clinical Scenario

With a lesion at the common peroneal nerve level, the foot tends toward plantarflexion and inversion. This pattern demands a more solid, less flexible ankle-foot orthosis (AFO) than is needed for isolated deep peroneal neuropathy — a distinction that directly influences which management steps apply.

Treatment Approach (Partial Overview)

When bracing proves insufficient, the protocol involves a surgical tendon transfer procedure aimed at restoring active dorsiflexion. The complete regimen — including the specific procedure, any required bony stabilisation, and the appropriate timing — is detailed in the full structured protocol.

If the lesion is at the level of the common peroneal nerve, the foot may tend toward plantarflexion and inversion.

Patients with common peroneal neuropathy require a more solid, less flexible AFO than those with only deep peroneal neuropathy.

If bracing is not effective, the tibialis posterior tendon can be transferred to the dorsum of the foot to restore active dorsiflexion.

This is often performed in conjunction with fusion of the subtalar joint and after one year post-injury.
