Rupture of the distal tendon of the biceps brachii. A biomechanical study.

The Biceps Crease Interval for Diagnosing Complete Distal Biceps Tendon Ruptures

“…At the time of subsequent surgical repair, this was observed to be attributable to an intact lacertus fibrosus. Other authors also have noted an intact lacertus fibrosus can limit proximal retraction of the distal biceps tendon [11,14]. Although the patient in our case had delayed presentation to our clinic (greater than 60 days postinjury) and a false-negative BCI test, there was no appreciable, detrimental clinical impact on the prognosis of his repair.…”

“…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].…”

The Biotenodesis Screw and Endobutton Technique for Repair for Acute Distal Biceps Tendon Rupture

“…Concerns over neurological complications, encouraged Boyd and Anderson to develop a 2-incision technique designed to minimize anterior exposure [15]: However, this technique introduced the potential complications of heterotopic ossification (HO) and proximal radio-ulnar synostosis [16]. The Mayo Group modified this approach by splitting the supinator and avoiding subperiosteal dissection and this led to a decrease in the rate of these specific complications [16]. Single incision techniques became more popular with the introduction of suture anchors, due to the ease of insertion and the belief that one incision caused less morbidity.…”

Chronic Distal Biceps Repair With an Achilles Allograft

“…This sudden overpowering force results in an acute avulsion of the distal tendon stump from the bicipital tuberosity. 2,3 Most often, distal bicep ruptures occur in the dominant arm (86%) of males between the ages of 30 and 50 years 4 with a history of tobacco use as a significant risk factor. 1,5 Despite its low annual incidence, distal biceps ruptures can lead to significant patient morbidity.…”
