The authors are grateful to a reader who highlighted a typo in the article. Instead of ‘…peroneal neuropathy can be differentiated from L5 radiculopathy by preserved strength of ankle inversion and of hip adduction’ this section should read: ‘…peroneal neuropathy can be differentiated from L5 radiculopathy by preserved strength of ankle inversion and of hip abduction.’

One study exploring the value of hip abductor strength in differentiating the localisation of foot drop, found that abductor weakness was present in 86% of patients with lumbar radiculopathy but only 4% of those with peroneal neuropathy.1

The authors would like to highlight that hip adduction is supplied by the obturator nerve (L2-4) and thus spared in both peroneal neuropathy and L5 radiculopathy.
