Morphometric profile of distal biceps tendon: A cadaveric approach

Research output: Contribution to journalArticlepeer-review


Background. The biceps muscle has proximal tendons that attach the muscle to the shoulder and one distal tendon that attaches at the elbow, called the distal biceps tendon. Normal morphometric measurements of the distal biceps tendon serve as an import-ant landmark in restoring its biomechanical characteristics and anthropometric evaluation during surgical tendon repairs. Hence the objective of this study was to provide a detailed morphometric profile of the distal biceps tendon. Methods. A total of 50 dissected adult limbs were studied. Out of the 50 limbs, 25 belonged to the right side while 25 were of the left side. The insertion pattern of the distal tendon was dissected and recorded. Total length, post aponeurotic length, the proximal, and distal thickness of the tendon was measured. Results were tabulated and correlated using SPSS. Results. The mean length of the tendon was 8 cm. The proximal thickness varied from 2 to 4 cm, distal thickness from 1 to 3 cm. Tendon length and thickness showed no statistically significant differences between the right and left sides. However, significant correlation (p < 0.001) was observed between length and thickness, proximal and distal thickness of the tendon. Conclusions. The variation in length, width of distal biceps footprints and radial tuber-osities may be significant in the anatomical restoration of the distal biceps tendon. This morphometric study of distal biceps tendon would be beneficial to sports medicine physicians for diagnosis and treatment of biceps tendon tear and tendinopathy.
