Abstract
Background: Peroneal tendon injuries, particularly of the peroneus longus, contribute to lateral ankle pain and instability. However, limited literature addresses the anatomical influence of the cuboid tunnel and the os peroneum on such injuries. This study investigates histological changes in the peroneus longus tendon and their relationship to cuboid tunnel dimensions, os peroneum presence, and age.
Methods: This cross-sectional study examined 60 peroneus longus tendons from 30 cadavers (ages 15-71). Tendons were sectioned and histologically analyzed for cellularity and collagen composition. Cuboid tunnel dimensions were measured, and the presence of os peroneum, an accessory ossicle located within the peroneus longus tendon, was recorded. Statistical correlations were performed.
Results: Increased type III collagen and cellularity were significantly associated with advanced age, reduced tunnel width, and increased tunnel height (p < 0.05). No significant association was found with tunnel length or os peroneum presence.
Conclusions: Age, reduced cuboid tunnel width, and increased tunnel height are associated with peroneus longus tendon degeneration, with collagen type I replacement by type III, predisposing factors for tendinosis.
期刊介绍：
Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society.
The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
