Ultrasound-Assisted Sural Nerve Biopsy: Technical Note and Correlation of Ultrasound Imaging with Operative Findings

The novel technique of ultrasound-assisted sural nerve biopsy is presented. Conventional sural nerve biopsy uses surgical landmarks to identify the sural nerve. However, the sural nerve location can vary. With the guidance of high-resolution ultrasound, the problem of nerve location variation is overcome, the skin incision is smaller, and tissue manipulation is minimized. The correlation of ultrasound imaging with operative findings is also presented.
