Rare Case Of Traction Sural Neuropathy Due To Acute Achilles Tendon Rupture, Heather Lystad, Kenneth Vitale Nov 2023

Rare Case Of Traction Sural Neuropathy Due To Acute Achilles Tendon Rupture, Heather Lystad, Kenneth Vitale

International Journal of Exercise Science: Conference Proceedings

Sural nerve injury (SNI) is a reported complication of acute Achilles tendon rupture (ATR), primarily iatrogenic in operatively managed cases. The sural nerve typically runs along the lateral border of the Achilles tendon. Its branches provide sensory information from the lateral foot and ankle. Given its proximity to the Achilles tendon, sural nerve-related complications in operatively managed cases are a known adverse outcome. However, the incidence of SNI in conservatively managed cases is thought to be much less common. Most patients recover to normal sensation by one year of injury to the sural nerve. CASE DESCRIPTION: A previously healthy 30 …
