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.
ABSTRACT
A hypertrophied peroneal tubercle can present as a bony prominence at the lateral aspect of the foot and a peroneal tenosynovitis or tear. We report a case of a 52-year-old man complaining of lateral foot tingling pain and numbness. The sural nerve entrapment and peroneus longus tenosynovitis by hypertrophied peroneal tubercle were confirmed. Good results were obtained after excision of the hypertrophied peroneal tubercle and sural nerve release.

An enlarged peroneal tubercle causes lateral ankle and foot pain, and which is a cause for stenosing peroneal tenosynovitis. In this report, we present a case of stenosing tenosynovitis of the peroneus longus tendon associated with hypertrophy of the peroneal tubercle without involvement of the peroneus brevis tendon. Surgical excision of the enlarged peroneal tubercle along with exploration of the peroneal tendons was successful.
