Damage to which nerve can lead to paresthesia when performing a tibial graft cortical window?

• A. Fibular nerve
• B. Sural nerve
• C. Gastroc nerve
• D. Medial plantar nerve

Answer: (B)

When performing a tibial graft cortical window, damage to the sural nerve can lead to paresthesia. The sural nerve is predominantly responsible for sensory innervation to the skin on the posterior aspect of the leg and the lateral aspect of the foot. During surgical procedures involving the tibia, especially when accessing the cortical bone, the position and manipulation of surrounding tissues can inadvertently place the sural nerve at risk. Paresthesia occurs as a result of irritation or damage to a sensory nerve, which can disrupt the normal transmission of nerve signals. In the case of the sural nerve, if it is injured or compressed during the surgical approach, patients may experience altered or diminished sensations in the areas it innervates, hence leading to paresthesia. Understanding the anatomical course and the sensory distribution of the sural nerve emphasizes the importance of careful dissection and manipulation during procedures involving the tibia. Recognizing this can assist surgeons in minimizing complications and providing better postoperative outcomes for patients.
