ABSTRACT

The fibularis brevis tendon and plantar aponeurosis lateral band are important in the pathogenesis of proximal fifth metatarsal fractures. This study aimed to evaluate the insertion morphology of the fibularis brevis tendon and plantar aponeurosis lateral band on the fifth metatarsal base using Korean cadavers. As the research object, we used 96 feet 48 Korean cadavers (33 male, 15 female), with an average age at death of 78.7±12.4 years. Morphological classification of the fibularis brevis tendon insertion was performed using the method of Imre et al. For morphological measurement, the length of the area where the fibularis brevis tendon and plantar aponeurosis lateral band were inserted was measured. The insertion of the fibularis brevis tendon was classified into three types: type 1 with one tendon in 51 feet (53.1%), type 2 with two tendons in 39 feet (40.6%), and type 3 with three tendons in 6 feet (6.2%). The length at the point of insertion with the fibularis brevis tendon was 14±4.3 mm, and the length at the point of insertion with the plantar aponeurosis lateral band was 14.1± 4.6 mm. In conclusion, this study suggests that the morphological characteristics of the fibularis brevis tendon and plantar aponeurosis lateral band could provide basic anatomical data for a new classification of avulsion fractures.
