The supramaximal stimulation was done at ankle, above, and below the fibular neck
The case of a 64-year-old male with a 2-day history of foot drop and tenderness in the region of the left fibular neck is presented.
Magnetic resonance imaging (MRI) revealed the presence of a fluid-filled mass, likely presenting a ganglion cyst, around the fibular neck, which compressed the common peroneal nerve (Fig.
It was compressing the peroneal nerve at the level of the fibular neck (Fig.
However, positive Tinel's sign and tenderness around the fibular neck can be keys to differentiate the root pathologies.
It arises at the level of the fibular neck and courses down the lateral compartment of the leg providing sensation to the dorsum of the foot and the toes.
Deep peroneal nerve: The deep peroneal nerve is a branch of the common peroneal nerve and, like the superficial branch, it emerges at the level of the fibular neck.
According to Preston and Shapiro (3) the common pattern is demyelination in the entrapment neuropathies, such as CTS radial neuropathy at the spiral groove, and peroneal neuropathy at the fibular neck
, but it is not seen in the non-localizing ulnar neuropathy.
The CPN continues to proceed laterally, where it passes behind the fibular neck.
In our series of patients with CPN injury at the fibular neck, Case 1 (a neurapraxic lesion) achieved full recovery of nerve function.
There is often marked tenderness at the fibular neck as well.
The accident resulted in severe bilateral below-knee degloving injuries with fractures of the ankle and the fibular neck
