Achilles Tendon or Sural Nerve?

In this video, Michael discusses three recent cases: two involving complications of post-operative Achilles tendon repair causing sural nerve entrapment neuropathy; and one patient previously treated for Achilles tendinopathy, which under more thorough investigation had inflammation of the sural nerve contributing to Achilles tendon pain.

The sural nerve provides sensory innervation to the Achilles tendon, posterior and inferior lateral calcaneus, and lateral aspect of the foot. Pain, therefore, in any of these areas, can be an indication of inflammation or irritation of the sural nerve or the proximal contributions to it.
