Vascular anatomy relevant to distal biceps tendon repair

Cadaveric study of anterior and posterior elbow endoscopy portals for endoscopic distal biceps repair: comparative anatomy-at-risk

“…Px proximal, Ds distal, RN radial nerve placement of the endoscope sheath over a Wissenger rod. We evaluated an outside-in technique for portal 5 placement, and found that the superficial radial nerve and posterior interosseous nerve are not at risk of injury while creating this portal (12). However, this portal traverses the interosseous membrane, and we did not evaluate the possibility of injury to the interosseous membrane or its adjacent vessels.…”

“…Endoscopic procedures around the distal biceps tendon necessitate endoscopic exploration of the cubital fossa and upper forearm, and may be potentially dangerous due to presence of several vital neurovascular structures in this region. In addition, the anatomical positions of neurovascular structures, and their relations to musculotendinous structures in the cubital fossa, are variable, and these structures are therefore susceptible to damage during portal placement [9,10,12].…”

Ultrasonography of Complications in Surgical Repair of the Distal Biceps Brachii Tendon

“…14,16 Vascularization of the DBBT usually depends on the brachial artery proximally and the recurrent radial artery, which crosses the tendon and usually runs superficial to it, distally. 17 In addition, a hypovascular zone with an average size of 2 cm was observed by Seiler et al 18 between the distal myotendinous junction and the distal end of the DBBT, and it could explain the higher prevalence of ruptures at this location. 3 The DBBT's preinsertional location is between the proximal ulna and the radial tuberosity.…”

“…The lacertus fibrosus is a fibrous expansion that originates from the radial side of the myotendinous junction of the long head, overlies and stabilizes the short head, and blends with the antebrachial fascia at the level of the flexor muscles of the forearm (Figures and ) . Vascularization of the DBBT usually depends on the brachial artery proximally and the recurrent radial artery, which crosses the tendon and usually runs superficial to it, distally . In addition, a hypovascular zone with an average size of 2 cm was observed by Seiler et al between the distal myotendinous junction and the distal end of the DBBT, and it could explain the higher prevalence of ruptures at this location .…”

High Bifurcation of the Brachial Artery: An Embryological Overview

“…On the other hand, this abnormal course makes arterial grafting and cardiac catheterization easier [22]. The abnormal arterial pattern of the upper arm, such as HBBA, might also complicate surgical procedures such as distal biceps tendon repair [23].…”
