Chronic distal biceps avulsion treated with suture button

Primary Repair of Chronic Distal Biceps Tendon Tears

BACKGROUND

This study reports the clinical results following primary repair of distal biceps tendon ruptures more 6 weeks after injury.

METHODS

A retrospective review of distal biceps tendon repairs performed by 8 different hand surgeons from January 1, 2015 to October 15, 2020 was performed. Patients with complete tears surgically treated ≥6 weeks after injury without tendon graft were included. Thirty patients qualified and underwent chart review for complication and range of motion (ROM) data. They were contacted for final patient-reported outcome measures (PROMs) using Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Patient Reported Elbow Evaluation (PREE) scores. Final PROMs were obtained from 21 patients with an average follow-up of 31.3 months (range: 4-71 months).

RESULTS

Average time from injury to repair was 71 days (range: 42-204). The average QuickDASH score was 6.6 (±6.2) and PREE score was 7.8 (±8.0). The amount of elbow flexion necessary to complete the repair was documented in 21 patients and averaged 64º (±10º). Postoperatively, patients achieved an average extension/flexion of 1º (±1º) to 138º (±2º) and pronation/supination of 76º (±4º) to 77º (±3º). Complications were reported in 14 patients (47%) and included 2 re-ruptures, 1 adhesive scar formation, 1 superficial infection, 1 intraoperative lateral antebrachial cutaneous nerve laceration, 12 neuropraxias, and 1 case of heterotopic ossification (HO).

CONCLUSIONS

Primary repair of chronic distal biceps tendon tears greater than 6 weeks from injury demonstrated excellent PROMs and elbow ROM. However, the complication rate may be higher than early repair.

Outcomes and Patient Satisfaction of Delayed Distal Biceps Repairs without Graft Augmentation: A Systematic Review

BACKGROUND

Distal biceps tendon tears are responsible for 3% to 10% of all biceps ruptures. Treated nonoperatively, these injuries result in poor endurance, loss of supination strength, and loss of flexion strength compared with those treated operatively with repair or reconstruction. When presenting in a chronic fashion, operative management can involve graft reconstruction or primary repair. When there is adequate tendon excursion and quality, primary repair is preferred. The purpose of this systematic review was to investigate the literature regarding outcomes of direct surgical repair of chronic distal biceps tendon ruptures.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to perform this systematic review and for the presentation of results. A search of the literature was performed on the electronic database Medline, Scopus, and the Cochrane Library. Included studies evaluated subjective and objective outcomes after delayed treatment (≥4 weeks postinjury) for chronic distal biceps tendon ruptures, without use of graft augmentation. Subjective and objective outcome metrics such as functional scores, range of motion, strength, pain level, and return to employment were collected.

RESULTS

Eight studies were reviewed. The studies included 124 patients with chronic distal biceps tendon tears, treated surgically after a mean delay to surgery of 121.8 days. Four studies included comparison of patients with acute and chronic tears, whereas the other 4 studies assessed chronic tears only. The findings of these 4 studies suggest that direct repair of chronic tears is correlated with a mildly higher rate of lateral antebrachial cutaneous nerve (LABCN) injury palsy (10/82 [12.1%] chronic vs. 3/38 [7.9%] acute, p = 0.753); however, this complication was overwhelmingly transient. There were only 3 reported reruptures (3.19%) across 5 studies reporting this complication. Overall, patients who had undergone direct repair of chronic distal biceps tears had good patient satisfaction, outcomes, and range of motion.

CONCLUSION

Direct repair of chronic distal biceps tendon tears without the use of graft reconstruction is associated with acceptable patient satisfaction, range of motion, and functional outcome scores, although transient LABCN palsy rates may be slightly higher. When sufficient residual tendon is present in the setting of chronic distal biceps rupture, direct repair is a viable treatment option. However, the existing literature regarding direct repair of chronic distal biceps repair is limited, and further prospective assessment directly comparing primary repair vs. reconstruction of chronic distal biceps ruptures is warranted.

Patient-Reported Outcome Measures of a Novel Cortical Button System for Distal Biceps Tendon Repair: A Retrospective Study

Background There are a number of different techniques available for the repair of distal biceps tendon ruptures. Recent evidence has revealed satisfactory clinical outcomes for suture button techniques. Aims The aim of this study was to determine if the ToggleLoc^TM soft tissue fixation device (Zimmer Biomet, Warsaw, Indiana) confers satisfactory clinical outcomes in the surgical management of distal biceps ruptures. Methods Twelve consecutive patients underwent distal biceps repair using the ToggleLoc^TM soft tissue fixation device over a two-year period. Patient-Reported Outcome Measures (PROMs) were collected by means of validated questionnaires on two occasions. Symptoms and function were quantified using the Disabilities of the Arm, Shoulder and Hand (DASH) score and the Oxford Elbow Score (OES). Patient-reported health scores were determined using the EQ-5D-3L (European Quality of Life 5 Dimensions 3 Level Version) questionnaire. Results The mean initial follow-up time was 10.4 months and the mean final follow-up time was 34.6 months. The mean DASH score at the initial follow-up was 5.9 (se = 3.6), compared to 2.9 (se = 1.0) at the final follow-up (p = 0.30). The mean OES at the initial follow-up was 91.5 (se = 4.1); and 91.5 (se = 5.2) at the final follow-up (p = 0.23). The mean EQ-5D-3L level sum score at the initial follow-up was 5.3 (se = 0.3); and 5.8 (se = 0.5) at the final follow-up (p = 0.34). Discussion The ToggleLoc^TM soft tissue fixation device confers satisfactory clinical outcomes, as determined by PROMS, in the surgical management of distal biceps ruptures.

All-suture anchors for distal biceps tendon repair: a preliminary outcome study

INTRODUCTION

The aim of this study was to retrospectively evaluate the clinical outcome of double intramedullary all-suture anchors' fixation for distal biceps tendon ruptures.

MATERIALS AND METHODS

A retrospective case series of patients who underwent primary distal biceps tendon repair with all-suture anchors was conducted. Functional outcome was assessed at a minimum follow-up of at 12 months based on the assessments of the Mayo Elbow Performance Score (MEPS), Andrews-Carson Score (ACS), Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH), and the Visual Analog Scale (VAS) for pain. Maximum isometric strength test for flexion and supination as well as postoperative range of motion (ROM) were determined for both arms.

RESULTS

23 patients treated with all-suture anchors were assessed at follow-up survey (mean age 56.5 ± 11.4 years, 96% male). The follow-up time was 20 months (range Q_0.25-Q_0.75, 15-23 months). The following outcome results were obtained: MEPS 100 (range Q_0.25-Q_0.75, 100-100); ACS 200 (range Q_0.25-Q_0.75, 195-200); QuickDASH 31 (range Q_0.25-Q_0.75, 30-31); VAS 0 (range Q_0.25-Q_0.75, 0-0). The mean strength compared to the uninjured side was 95.6% (range Q_0.25-Q_0.75, 80.9-104%) for flexion and 91.8 ± 11.6% for supination. There was no significant difference in ROM or strength compared to the uninjured side and no complications were observed in any patient.

CONCLUSION

Distal biceps tendon refixation using all-suture anchors provides good-to-excellent results in terms of patient-reported and functional outcome. This repair technique appears to be a viable surgical option, although further long-term results are needed.

Outcomes and complications after different surgical techniques for the treatment of chronic distal biceps tendon ruptures: a systematic review and quantitative synthesis

Hypothesis

The purpose of this study was to perform a systematic review of the available literature evaluating surgical outcomes after chronic distal biceps tendon rupture. Surgical techniques, including primary repair, autograft reconstruction, and allograft reconstruction, were compared, as well as subjective and objective clinical outcomes and complication rates.

Methods

A systematic literature search of Level I-IV studies reporting outcomes of surgically treated chronic distal biceps tendon ruptures were performed via PubMed, Cochrane Collaboration, Science Direct, and Google Scholar databases. Twenty-two papers were identified in the review, with 236 patients. A Modified Coleman Methodological Score (CMS) was determined for every article to assess study quality. Patient-reported outcomes, postoperative range of motion, flexion and supination strength, and postoperative complications were recorded. MAYO elbow scores (MEPS) were reported more consistently than the other outcome tools.

Results

No Level I or level II studies were identified in our search, and the heterogeneity of outcome measures precluded meta-analysis. Studies demonstrated mean MEPS scores ranging between 86 and 100, regardless of the surgical technique utilized. All studies reported a mean flexion-extension arc equal to or greater than 5-130°. The reported mean postoperative flexion strength was within 10% of the unaffected contralateral side. The most common complication for both direct repair and reconstruction groups was paresthesia of the lateral antebrachial cutaneous nerve [direct repair: 18-16.8%; reconstruction: 8-6.2% (allograft: 4-6%; autograft: 4-7%)]. Rerupture was uncommon and occurred in three patients who had undergone direct repair and in one patient after autograft reconstruction.

Conclusions

Surgical treatment of chronic distal biceps injuries yields favorable objective and subjective outcomes. Currently, available evidence suggests that direct repair, autograft reconstruction, or allograft reconstruction are all viable treatment options with similar outcomes.

Surgical Results of Chronic Distal Biceps Ruptures: A Systematic Review

Background:

Distal biceps tendon tears can cause weakness and fatigue with activities requiring elbow flexion and supination. Surgical management of chronic tears (>21 days) is not well described in the literature.

Purpose:

To determine the clinical outcomes of chronic distal biceps repairs and reconstructions.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

We performed a search of Medline (PubMed and Ovid), EMBASE, CINAHL physical therapy, Cochrane Database of Systematic Reviews and Central Register of Controlled Trials, and PubMed Central from inception until September 29, 2020, to identify articles on chronic distal biceps ruptures. The inclusion criteria were studies with at least 1 outcome measure and 10 patients with chronic distal biceps ruptures treated surgically. The quality of the included studies was assessed with the methodological index for nonrandomized studies (MINORS) score. Functional outcomes and complications were reviewed.

Results:

A total of 12 studies were included after systematic database screenings. The MINORS scores ranged from 5 to 19. There were a total of 1704 distal biceps ruptures, of which 1270 were acute and 434 were chronic. Average follow-up time was 12 months to 5.1 years. Single-incision (n = 3), 2-incision (n = 2), or both (n = 6) surgical techniques were used in these studies. Four studies described the use of autografts, and 4 articles used allografts in the chronic repair. Range of motion, function, and strength outcomes were similar when compared with the contralateral arm. Pain was reduced to minimal levels. Main postoperative complications were of paresthesia (specifically to the lateral antebrachial cutaneous nerve), which were temporary in 69.1% of cases.

Conclusion:

The results of this review indicate that surgical management of chronic distal biceps ruptures demonstrates improvement in outcomes including pain reduction and functional ability. Although there may be a slightly higher immediate complication rate, the functional outcomes remain comparable with those seen in the patient population with acute distal biceps.
