Ultrasound measurements of the normal peroneal tubercle: validation of the normal anatomical measurements and evaluation of the intra- and interobserver reliability.

Purpose: The aim of this study was to investigate if ultrasound could be a reliable and accurate tool to measure the size of the peroneal tubercle.
Material and Methods: This study measured the width, length, and height of the peroneal tubercle in 100 asymptomatic patients, comparing the measurements to prior radiographs of the foot (if available) and previously reported anatomical data. This study also assessed the intra- and interrater reliability of ultrasound as a measurement tool.
Results: Our findings show that ultrasound measurements of the peroneal tubercle were consistent with values reported in the literature and prior radiographs concerning width. Both intra- and inter-observer measurements were reliable.
Conclusions: This study highlights the potential of ultrasound imaging as a promising tool to measure the peroneal tubercle, and it could contribute to a better understanding of peroneal tendon disorders.
Competing Interests: The authors report no conflicts of interest.
