Classification of peroneal muscle trochlear and its correlation with calcaneus / 解剖学报

ABSTRACT

Objective To measure and classify the trochlear size of fibular muscle, and to analyze its correlation with calcaneus. Methods In 824 calcaneal specimens, the length, width and height of the peroneal muscle trochlear were measured and classified according to the four types of flat, convex, concave and tunnel. Results The prevalence of the peroneal tubercle was 62. 5%. The average length, width, and height of the tubercle were ( 11.5±3.32) (2.56-23.14) mm, (6.27±2.20) (1.34-14.99)mm, and (2.69±1.30) (0.41-8.18)mm respectively. The four types of peroneal tubercle were classified as flat in 191 (37.09%), prominent in 189 (36.7%), concave in 131 (25.44%), and tunnel in 4 (0.77%). Conclusion This data may help understand pathology of peroneus tendon and its relationship with peroneal tubercle, and it may help make standard to define the abnormal peroneal tubercle.
