This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview

• Surgical treatment of chronic distal biceps injuries yields favorable objective and subjective outcomes [1].
• The short-term clinical influence of biceps complications on shoulder outcome is very limited [2].
• The overall frequency of reported complications is higher for single-incision distal biceps repair than for double-incision repair [3].
• Surgical repair of distal biceps tendon ruptures has an overall low rate of serious complications regardless of approach or technique [4].
• Bioabsorbable interference screw fixation of distal biceps ruptures through a single anterior incision is a safe and successful technique for the management of distal biceps tendon ruptures [7].
• Complication rates after distal biceps repair are low [8].
• Patients undergoing distal biceps reconstruction with graft augmentation can expect low complications and good functional results [10].
• Direct repair in the acute setting is preferred over reconstruction with graft augmentation [10].
• Distal biceps repair is associated with a 7.5% major complication rate [12].
• Distal biceps repair is associated with a 4.5% reoperation rate [12].

Anatomy & Pathophysiology

• Thorough knowledge of distal biceps insertional and footprint anatomy is essential for understanding the biomechanics of rupture and reconstruction, and for avoiding nerve injuries [32].
• Distal biceps MRI signal changes consistent with tendinopathy are common in asymptomatic elbows, reducing the probability that symptoms correlate with imaging pathology [29].
• Nonoperative management does not restore function to the elbow in cases of chronic biceps tendon rupture [24].
• Nonoperative treatment of distal biceps rupture may lead to permanent loss of arm function [50].
• Surgical repair of the distal biceps insertion reliably regains both supination and flexion strength in appropriate patients [44].
• Distal biceps repair or reconstruction can restore near-normal flexion and supination strength [42].
• Surgical repair restores supination strength, although outcomes vary [43].
• Operative treatment results in superior elbow and forearm strength and endurance, as well as superior DASH and MEPS scores, compared to nonoperative management [41].
• For patients with higher-demand occupations, surgical repair results in a greater likelihood of rating elbow function as much better compared to nonoperative management [26].
• Most methods of fixation provide adequate strength to allow early active range of motion, with complications being similar between groups using modern surgical techniques [47].
• There is no significant difference in range of motion and strength between different approaches and fixation techniques for distal biceps tendon ruptures [48].
• Fixation constructs using an extramedullary cortical button with or without an interference screw, or two intramedullary cortical buttons, demonstrate biomechanical properties comparable to or superior to the native tendon [45].

Classification

• Partial distal biceps tendon tears encompass a spectrum of disease with variable presentation and morphology [6].
• Isolated short head ruptures are a rare and distinct form of distal biceps tear that present with consistent clinical findings that can aid in diagnosis [11].
• The surgical repair of distal biceps tendon ruptures has an overall low rate of serious complications, regardless of approach or technique [13].
• The evidence-based diagnostic algorithm using the combination of the Flexion Initiation Test (FIT) and hook test demonstrates high accuracy for the diagnosis of both complete and high-grade partial distal biceps tendon tears [16].
• The modified two-incision approach is the current gold standard for distal biceps tendon repairs, though anterior approaches are also effective with similar rerupture rates [20].
• The incidence of women sustaining a distal biceps tendon tear is 3.2%, with partial tears being statistically more common than complete ruptures [22].
• Anterior single incision techniques were used in the majority of cases in a large cohort study of distal biceps tendon repairs, with varying fixation methods [38].

Clinical Presentation

• Chronic distal biceps injuries present with a spectrum of disease where surgical treatment yields favorable objective and subjective outcomes [1].
• Biceps-related complications after tenotomy associated with arthroscopic rotator cuff repair have very limited short-term clinical influence on shoulder outcome [2].
• Isolated distal biceps femoris injuries occurred primarily via noncontact mechanisms [18].
• The prevalence of distal biceps tendon signal changes on MRI in asymptomatic patients is very low [23].

Investigations

• Distal biceps MRI signal changes consistent with tendinopathy are common even in asymptomatic elbows, which reduces the probability that symptoms correlate with pathology on imaging [29].

Treatment

• Surgical management of chronic distal biceps ruptures demonstrates improvement in outcomes including pain reduction and functional ability [9].
• Bioabsorbable interference screw fixation of distal biceps ruptures through a single anterior incision is a safe and successful technique [7].
• The early complication rate following partial distal biceps tendon repair was 20.5% [19].
• Distal biceps repair is associated with a 7.5% major complication rate and 4.5% reoperation rate [12].
• Surgical management of distal biceps tears was a predictor of improved patient-reported outcomes only for patients with complete tears [17].
• The results of the meta-analysis showed the superiority of surgical management over the nonoperative approach for distal biceps tendon detachment, with superior flexion and supination strength and better patient-reported outcomes [34].
• For patients with higher-demand occupations, surgical repair resulted in a greater likelihood of rating elbow function as much better compared to nonoperative management [26].
• Workers' compensation patients who underwent distal biceps tendon repair took longer to return to work and had worse DASH scores than non-workers' compensation patients [40].
• Nonoperative management does not restore function to the elbow [24].

Complications

• Patients should be counseled that 1 in 5 patients will have a minor complication and 1 in 20 patients will have a major complication after surgery on the distal biceps tendon [21].
• Complication rates after distal biceps tendon repair performed by newly trained surgeons were similar to those previously reported in large cohort studies, with nerve injury as the most common complication [25].
• This is the largest analysis of complications after distal biceps repair, indicating a major complication rate of 4.6% [31].

Recovery

• Direct repair in the acute setting is preferred, but patients undergoing distal biceps reconstruction with graft augmentation can expect low complications and good functional results [10].
• The modified two-incision approach is the current gold standard, though anterior approaches are also effective with similar rerupture rates [20].
• One in five patients will have a minor complication and one in twenty patients will have a major complication after surgery on the distal biceps tendon [21].
• Even in the setting of a distal biceps reconstruction with graft augmentation, patients can expect a similar result to primary repair [27].
• The average time to return to work after distal biceps repair in the literature was just beyond 14 weeks [46].
• Timing significantly impacts surgical technique selection in distal biceps ruptures, with direct repair favored for acute injuries and high flexion angle repair or allograft reconstruction for chronic cases [51].
