“…Unlike other tendon ruptures, which can occur intrasubstance or at the musculotendinous junction, a complete distal biceps tendon rupture almost always occurs at the tendon's insertion to the radial tuberosity. The functional superiority of anatomic surgical repair for this injury is now well established and has gained acceptance as the preferred treatment option for restoring strength in supination and flexion [2,5,12,13,14,16]. If surgical treatment of a complete distal biceps tendon rupture is delayed, a combination of muscle retraction, adhesion formation, distal tendon shortening, and degeneration can make anatomic reinsertion of the original tendon difficult [14,16,22].…”
