Insertional anatomy and clinical relevance of the distal biceps tendon

Abstract

This study confirmed that bifurcated distal biceps tendon insertion is not a rare anatomical variation, showed by recent investigations, and found that the short head of the distal biceps tendon was inserted more anteriorly than the long head on the radial tuberosity. These findings may allow functional independence and isolated rupture of each portion. It can make correct diagnosis possible and allow for a more anatomical orientation of the tendon during surgical repair.

Bicipital tuberosity bone characteristics in surgical reattachment of the distal biceps: anatomical and radiological study

“…Several authors have described the extreme variability of the shape of the bicipital tendon in its insertion into the radial tuberosity [1,2,6,8,10,11]. We believe this is a crucial aspect because it makes it impossible to reproduce it.…”

Chronic Partial Rupture of Distal Biceps Tendon in an Adolescent―A Case Report

“…The deep tendinous fibers of both heads form the main tendon of distal biceps, which enters the lateral aspect of the cubital fossa to attach at the radial tuberosity [7]. The two independent muscle bellies with a bifurcated distal biceps tendon probably allows functional independence and isolated rupture of each portion [15]. The biceps tendon is normally separated from the anterior portion of the radial tuberosity by a bursa [12].…”

Upper Limb Ischaemia Secondary to a Bifurcated Distal Biceps Tendon: A Case Report

“…A bifurcated distal biceps tendon was first reported by Sassmannshausen et al 3 and has subsequently been noted in 48% of cadaveric specimens. 4 It does not, however, commonly present clinically and has never been reported to compress the brachial artery. While both popliteal arterial entrapment and thoracic outlet syndrome are well documented, forearm arterial entrapment remains rare.…”
