Biceps brachii tendon ruptures: a review of diagnosis and treatment of proximal and distal biceps tendon ruptures

Open Subpectoral Tenodesis for Isolated Traumatic Long Head of Biceps Tendon Rupture Provides Excellent Functional Outcomes in Active Male Patients

Background: For many years the long head of biceps tendon (LHBT) rupture has been described and is commonly identified by weakness, cramping, and the so-called "Popeye" sign. Traditionally, this was treated non-operatively, likely reflecting patient factors and the technical difficulty in reattaching a degenerative and shortened tendon. In contrast, traumatic distal biceps rupture is now commonly repaired despite historically being managed non-operatively. The advent of a convenient and reproducible surgical technique led to an increase in the rate of fixation, thereby improving the cramping and weakness associated with non-operative treatment. Given recent surgical advances within this field, many techniques are now present for LHBT pathology. We describe results from a cohort of patients suffering traumatic LHBT rupture who sought a surgical solution to improve their symptoms.

Methods: Over four years, 18 male patients underwent surgical intervention for isolated traumatic LHBT rupture. The technique used involved an open subpectoral tenodesis with fixation of the LHBT into the bicipital groove. Postoperative immobilization using a sling was recommended for six weeks prior to a progressive rehabilitation program. Patients were assessed with pre- and postoperative visual analog scores (VAS) for pain and American Shoulder and Elbow Society (ASES) scores.

Results: The mean patient age at the time of surgery was 49 years (range: 26-65 years). The mean time to surgery was nine weeks (range: 2-24 weeks). All patients showed an improvement following surgery with a mean pre-op ASES score of 33 (range: 10-60) compared to a post-op score of 92.6 (range: 85-100). All patients were able to return to work and sport, with all but one returning to the same functional demand level of work. The mean pre-op pain VAS was 6.3 (out of 10) compared to 0.2 post-op. All patients had a requirement for analgesia pre-operatively and none had postoperatively. No surgical complications were observed. No correlation was observed between the time to surgery and the outcome.

Discussion: LHBT rupture is often treated non-operatively as few studies within the literature describe the surgical technique and outcomes from surgical intervention. When treated non-operatively, patients complain of pain, cramping, and cosmetic deformity known as the "Popeye" sign. Following a traumatic rupture of the LHBT, we have demonstrated excellent outcomes using a standard approach and common fixation technique that has the potential to improve the functional outcome for symptomatic patients.

Conclusion: Open subpectoral biceps tenodesis is associated with excellent outcomes in symptomatic patients following isolated LHBT rupture.

Clinical Evaluation of the Reconstruction of the Biceps Brachii using Triceps Graft

Objective  Clinical and functional evaluation of the surgical treatment for chronic injury of the distal biceps brachii applying a surgical technique with grafting of the distal triceps brachii tendon. Methods  A study based on a review of the medical records and clinical evaluation of the patients submitted to surgical treatment for chronic injury to the distal insertion of the biceps brachii between February 2015 and February 2017. In a 12-month-minimum postoperative follow-up, 7 patients were evaluated regarding the range of motion of the operated and non-operated elbows, flexion, upper-limb extension and supination with a digital dynamometer, the hook test, the satisfaction index, and the Disabilities of the Arm, Shoulder and Hand (DASH) and Mayo Elbow Performance Score (MEPS) intruments. Results  During the postoperative functional evaluation, no patient reported dissatisfaction with the esthetic outcome of the incisions, and all of them were satisfied/very satisfied with the range of motion and strength of the operated limb. No neurovascular complications, surgical site infection or tendon rupture were observed. On the MEPS and DASH scales, all patients scored 100 and 0 respectively. The mean flexion was of 133.5° on the operated side, versus 139.2° on the non-operated side. The mean extension was of 5° on the operated side versus 0° on the non-operated side. The supination was of 86.5° versus 90°, and the pronation, 80° versus 80°, when comparing the operated and non-operated sides respectively. The mean flexion, extension and supination corresponded respectively to 92.5%, 96.4% and 86.8% of those of the non-operated limb. Conclusion  Recosntruction of the distal biceps brachii with triceps grafting seems to be an effective and safe option for the treatment of chronic distal biceps injuries.

All-suture anchor and unicortical button show comparable biomechanical properties for onlay subpectoral biceps tenodesis

Hypothesis

The purpose of this study was to biomechanically evaluate onlay subpectoral long head of the biceps (LHB) tenodesis with all-suture anchors and unicortical buttons in cadaveric specimens.

Methods

After evaluation of bone mineral density, 18 fresh-frozen, unpaired human cadaveric shoulders were randomly assigned to 2 groups: One group received an onlay subpectoral LHB tenodesis with 1 all-suture anchor, whereas the other group received a tenodesis with 1 unicortical button. The specimens were mounted in a servo-hydraulic material testing system. Tendons were initially loaded from 5 N to 100 N for 5000 cycles at 1 Hz. Displacement of the repair constructs was observed with optical tracking. After cyclic loading, each specimen was loaded to failure at a rate of 1 mm/s.

Results

The mean displacement after cyclic loading was 6.77 ± 3.15 mm in the all-suture anchor group and 8.41 ± 3.17 mm in the unicortical button group (P = not significant). The mean load to failure was 278.05 ± 38.77 N for all-suture anchor repairs and 291.36 ± 49.69 N for unicortical button repairs (P = not significant). The most common mode of failure in both groups was LHB tendon tearing. There were no significant differences between the 2 groups regarding specimen age (58.33 ± 4.37 years vs. 58.78 ± 5.33 years) and bone mineral density (0.50 ± 0.17 g/cm² vs. 0.44 ± 0.19 g/cm²).

Conclusion

All-suture anchors and unicortical buttons are biomechanically equivalent in displacement and load-to-failure testing for LHB tenodesis. All-suture anchors can be considered a validated alternative for onlay subpectoral LHB tenodesis.

Rupture of the long head of the biceps brachii tendon near the musculotendinous junction in a young patient: A case report

We report an unusual case of the long head of the biceps brachii tendon rupture near the musculotendinous junction in a young patient. The injury occurred in a young athlete during sports competition. The clinical presentation, surgical treatment, and technique with tenodesis using a unicortical button of the ruptured tendon were presented. The post-surgical recovery was uneventful, and the patient returned to sports in 6 mo. The treatment approach and surgical technique of the long head of biceps brachii rupture was reviewed and discussed. In conclusion, surgical treatment of the long head of the biceps brachii tendon rupture with unicortical button tenodesis resulted in a favorable outcome in a young athlete.

Reconstruction of the distal biceps tendon using semitendinosus grafting: Description of the technique

Distal ruptures of the biceps are rare when compared to proximal ruptures, with a different epidemiology and mechanism of trauma. There is no exact pathophysiology, though the hypovascular distal insertion and the mechanical impact during movement should be considered important factors. The surgical treatment of chronic cases presents worse prognosis due to muscle shortening with tendon retraction, making anatomical repair of the injury difficult, requiring the use of grafts for its reconstruction. This is a prospective study involving four patients with chronic distal biceps injury. The tendons were reconstructed with an autologous graft from the semitendinosus tendon from the ipsilateral knee and secured to the radial tuberositywith the help of two anchors. The surgical technique proved to be a simple and viable procedure for the reconstruction of chronic ruptures of the distal biceps.

Single-Incision Anatomic Repair Technique for Distal Biceps Tendon Rupture Using Tunneling Device

Distal biceps tendon ruptures are uncommon and generally occur in men aged 30 to 50 years in their dominant arm as a result of a strong eccentric load. Numerous surgical exposures and methods of fixation exist for repair of a ruptured distal biceps tendon. The goal of surgical management is to restore the anatomic footprint of the biceps tendon on the radial tuberosity to maximize flexion strength, supination strength, and muscle endurance. When compared with 2-incision repair techniques, single-incision repairs historically may not have restored the anatomic footprint of the distal biceps. Single-incision repair with the ArthroTunneler is a safe and effective technique that provides the anatomic restoration of a 2-incision approach with the decreased complication profile of a single-incision approach and does not require suture anchors, buttons, screws, or other implants.

Direct repair of chronic distal biceps tendon tears

OBJECTIVE

To present the results from direct tendon repair using EndoButton and interference screws in patients with lesions of the distal biceps that had evolved over a period of more than 28 days.

METHODS

Between January 2012 and November 2013, eleven patients (all male) with a torn distal biceps and a time interval between injury and surgery of more than 28 days were evaluated. The patients' mean age was 46 years and the most common mechanism of injury was eccentric loading with the elbow flexed and supinated.

RESULTS

A subjective analysis on pain and function was conducted using a visual analog scale of pain (VAS) and the Mayo Elbow Performance Score (MEPS), before and after surgery. The VAS showed a decrease of 5 points to 0.8 points on average. The MEPS improved from 69.3 points before the operation to 97.5 points afterwards. The mean flexion was 133.1° on the operated side, versus 134.3°. The mean extension was -2.5° and 0° (operated side versus non-operated). Supination was 88.2° versus 89.5° and pronation was 82.5° versus 84.1°, comparing the operated side versus the non-operated side. Flexion and supination strengths were evaluated with the aid of a dynamometer, and the mean flexion and supination strengths were found to be respectively 78.57% and 89.65% of the strength of the non-operated limb.

CONCLUSION

Use of the technique of direct tendon repair using EndoButton and interference screws was shown to be a safe and effective alternative for repairing chronic lesions of the distal biceps.

Rupture of the Long Head of the Biceps Tendon in a Pediatric Athlete: A Case Report

CASE

We report a case of an adolescent athlete who sustained an isolated rupture of the long head of the biceps tendon and was subsequently treated with subpectoral biceps tenodesis.

CONCLUSION

Provided that there is no damage to the rotator cuff, an open biceps tenodesis may be performed in this young patient population with good short-term outcomes and return to full activity.

Repair of distal biceps brachii tendon assessed with 3-T magnetic resonance imaging and correlation with functional outcome

OBJECTIVE

Objectives were to study the MRI appearance of the repaired distal biceps tendon (DBT), anatomically reinserted, and to search for a correlation between tendon measurements and functional results.

MATERIALS AND METHODS

Twenty-five patients (mean age, 49 ± 4.9 years old) who benefited from 3-T MRI follow-up of the elbow after surgical reinsertion of the DBT were retrospectively included and compared to a control group (n = 25; mean age, 48 ± 10 years old). MRI was performed during the month of clinical follow-up and on average 22 months after surgery. Delayed complications (secondary avulsion, new rupture), intratendinous osteoma, tendinous signal on T1-weighted (T1w) and fat-suppressed proton density-weighted (FS-PDw) images as well as DBT measurements were recorded. The maximum isometric elbow flexion strength (MEFS) and range of motion of the elbow were assessed.

RESULTS

Repaired DBT demonstrated a heterogeneous but normally fibrillar structure. Its low T1w signal was less pronounced than that of normal tendons, and the FS-PDW image signal was similar to that of T1w images. MRI detected seven osteomas (Se = 53 % vs. plain radiography), one textiloma and one secondary avulsion. Repaired DBT measurements were significantly correlated with MEFS (dominant arm R2: 0.38; nondominant arm R2: 0.54); this correlation involved the insertion surface (Δ = -75.7 mm(2), p = 0.046), transverse diameter (Δ = -2.6 mm, p = 0.018), anteroposterior diameter at the level of the radial head (Δ = -3.9 mm, p = 0.001) and DBT cross-sectional area (Δ = -50.2 mm(2), p = 0.003).

CONCLUSION

The quality of functional outcome after anatomical elbow rehabilitation of DBT correlates with the extent of tendinous hypertrophy during the healing process.

Closed proximal muscle rupture of the biceps brachii in wakeboarders

Closed proximal muscle rupture of the biceps brachii is a rare injury. In this report, two cases of closed proximal muscle rupture of the biceps brachii after wakeboard traumas are described. Both patients presented with a swollen arm, weakness during flexion, and a mass in the affected forearm. Magnetic resonance imaging showed displacement of the biceps brachii into the forearm. The rupture was successfully treated with muscle removal in one case and muscle repair in the other. In patients with a wakeboard trauma and similar presentations, closed proximal muscle rupture of the biceps brachii should be suspected.
