Resumen
Distal biceps tendon (DBT) insertion on the el-bow bicipital tuberosity is usually bifurcated into distinct long and short head components, and oc-casionally the tendon may insert as a single unit. A previously undescribed trifurcate insertion of the DBT was observed during anatomical dissections; this new anatomical finding involved 3 distinct divi-sions of the distal biceps: (1) a distal short head insertion, (2) a proximal long head insertion, and (3) an extra / accessory head that bifurcated from the long head and inserted with an anterior and radial footprint. Recognition of this variant is nec-essary, as DBT insertional trifurcation may alter radiological interpretation of imaging scans and may obscure endoscopic visualization of the inser-tional area during diagnostic endoscopy.
