Repair of distal biceps tendon acute ruptures with two suture anchors and anterior mini-open single incision technique: clinical follow-up and isokinetic evaluation

Return to Sport After Distal Biceps Tendon Repair: A Systematic Review

BACKGROUND

Ruptures of the distal biceps tendon (DBT) can affect the range of motion and strength of the elbow, raising concerns for patients seeking to restore normal function and engage in their regular activities, particularly returning to previous levels of sport participation.

PURPOSE

To characterize and assess the rate and timing of return to sport (RTS) after DBT repair.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

PubMed, Embase, and Google Scholar (pages 1-20) were searched from database inception to December 6, 2023 for clinical studies reporting RTS outcomes after DBT repair. The extracted data consisted of patient characteristics; information on the incision approach, fixation method, and rehabilitation protocol; and outcome data including RTS rates, patient-reported outcome measure scores, and complications.

RESULTS

A total of 42 studies, including 1093 patients (1100 elbows), met the inclusion criteria. The mean age of patients was 44.9 years, and 99.2% of patients were male. The mean follow-up time was 31.5 months. Ruptures were acute in 87.6% of cases, the dominant arm was injured in 64.9%, and the cause of the injury was sport related in 43.5%. The overall RTS rate was 91.5%, with 85.2% of patients returning to preinjury levels or higher, at a mean time of 6.3 months. Patients had excellent functional outcomes, irrespective of the incision approach or fixation method, although trends associated with a higher RTS rate were observed with bone tunnel fixation, ≤2 weeks of postoperative immobilization, early initiation of active range of motion postoperatively, and initiation of strengthening at ≤10 weeks. Single-incision repair had higher rates of nerve-related complications and reruptures compared with double-incision repair, and cortical button fixation had a higher rate of nerve-related complications among the fixation methods.

CONCLUSION

There was a high rate of RTS after DBT repair at 6 months postoperatively. A positive trend for RTS was observed with respect to rehabilitation protocols favoring earlier active mobility.

Operative Versus Nonoperative Management for Distal Biceps Brachii Tendon Lesions: A Systematic Review and Meta-analysis

BACKGROUND

Both nonoperative and operative treatments have been proposed to manage distal biceps brachii tendon avulsions. However, the advantages and disadvantages of these approaches have not been properly quantified.

PURPOSE

To summarize the current literature on both nonoperative and operative approaches for distal biceps brachii tendon ruptures and to quantify results and limitations. The advantages and disadvantages of the different surgical strategies were investigated as well.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

A systematic literature search was performed in March 2020 using PubMed Central, Web of Science, Cochrane Library, MEDLINE, Iscrctn.com, clinicaltrials.gov, greylit.org, opengrey.eu, and Scopus literature databases. All human studies evaluating the clinical outcome of nonoperative treatment as well as different surgical techniques were included. The influence of the treatment approach was assessed in terms of the Disabilities of the Arm, Shoulder and Hand (DASH) score and the Mayo Elbow Performance Index; extension, flexion, supination, and pronation range of motion (ROM); and flexion and supination strength ratio between the injured and uninjured arms. Risk of bias and quality of evidence were assessed using the Cochrane guidelines.

RESULTS

Of 1275 studies, 53 studies (N = 1380 patients) matched the inclusion criteria. The results of the meta-analysis comparing operative versus nonoperative approaches for distal biceps tendon avulsion showed significant differences in favor of surgery in terms of DASH score (P = .02), Mayo Elbow Performance Index (P < .001), flexion strength (94.7% vs 83.0%, respectively; P < .001), and supination strength (89.2% vs 62.6%, respectively; P < .001). The surgical approach presented 10% heterotopic ossifications, 10% transient sensory nerve injuries, 1.6% transient motor nerve injuries, and a 0.1% rate of persistent motorial disorders. Comparison of the different surgical techniques showed similar results for the fixation methods, whereas the single-incision technique led to a better pronation ROM versus the double-incision approach (81.5° vs 76.1°, respectively; P = .01).

CONCLUSION

The results of this 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. The single-incision surgical approach demonstrated a slightly better pronation ROM compared with the double-incision approach, whereas all fixation methods led to similar outcomes.

Return to work following a distal biceps repair: a systematic review of the literature

BACKGROUND

Among an active aging population, distal biceps tendon ruptures are becoming increasingly common. Typically, they are the result of an acute heavy eccentric load being placed on an already contracted muscle, and surgery is the gold standard treatment for optimal clinical and functional outcomes. Although improved strength has been shown after operative repair, there is little evidence available regarding a timeframe for return to work-related activity. The purpose of this study was to conduct a systematic review of the literature to provide guidance for return to work after a distal biceps repair.

METHODS

The authors searched online databases (EMBASE, MEDLINE) from inception until October 11, 2018, for literature pertaining to functional outcomes after distal biceps repair. Study inclusion and exclusion criteria were established a priori and applied in duplicate independently by 2 reviewers.

RESULTS

Of the 480 initial studies, 40 papers satisfied full text inclusion criteria (19 case control studies, 12 retrospective reviews, 9 prospective reviews). A total of 1270 patients with 1280 distal bicep ruptures were included in the study. The mean age of patients was 45.38 years, and 97% (n = 1067) of reported patients were male. The mean follow-up time was 30 months (range, 6-84 months). After distal biceps repair, 1128 (89%) of patients were able to fully return to work without any modification of duties. Time to return to work was reported in 17 of the included studies with a mean of 14.37 ± 0.52 weeks.

DISCUSSION

The average time to return to work after distal biceps repair in the literature was just beyond 14 weeks. Patients and employers may be given a range between 3 and 4 months, with variation dependent on job demands. Further studies are needed to establish whether the surgical approach or repair technique has any impact on time to return to work.

Intramedullary Cortical Button Repair for Distal Biceps Tendon Rupture: A Single-Center Experience

PURPOSE

The aim of this retrospective study was to evaluate the clinical outcome and complication rate of intramedullary cortical button repair for distal biceps tendon rupture (partial and complete tears).

METHODS

Between 2010 and 2014, a total of 28 patients with an acute distal biceps tendon rupture underwent intramedullary cortical button repair. Twenty-four patients (mean age, 49 years) with a mean follow-up of 28 months were included in the study. Twenty patients were examined clinically and by maximum isometric strength testing in flexion (at 90°) and supination of both arms. Twenty-four patients completed functional scores including the Mayo Elbow Performance Score (MEPS), the Andrews-Carson-Score (ACS) and the shortened Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire. Furthermore, follow-up radiographs of 24 patients were analyzed.

RESULTS

Compared with the contralateral elbow, the active range of motion (ROM) was the same. The mean strength for flexion was 100.8% ± 14% and for supination 93.1% ± 22% compared with the uninjured side. The mean MEPS for all patients was 95.6 ± 8.2, the mean ACS 194.2 ± 9.4 and the QuickDASH 3.8 ± 7.6. Heterotopic ossification (HO) was seen on radiographs in 46% of patients, but was symptomatic in only 1 patient. One patient suffered a tendon rerupture, and 1 asymptomatic button migration was seen in the follow-up.

CONCLUSIONS

Intramedullary cortical button repair provides good results with respect to strength, ROM, and functional outcomes. Because the posterior cortex is not violated, the risk of iatrogenic posterior interosseous nerve injury is minimized. However, the patient should be warned of a high prevalence of postoperative HO.

A Single-Incision Technique for Distal Biceps Repair Using a Flexible Reamer

Distal biceps tendon ruptures are rare injuries that usually occur in middle-aged men. Most of these injuries are repaired acutely to restore preinjury function and strength. There is concern regarding the higher prevalence of certain complications with the double-incision technique. As such, the single-incision technique has also been studied to determine if it may produce superior safety and efficacy. In addition, the point of fixation may be created with either a rigid or a flexible reamer. The authors describe a technique that uses a single-incision cortical fixation achieved with a flexible reamer. [Orthopedics. 2017; 40(4):e744-e748.].

Single Incision Distal Biceps Repair With Hemi-Krackow Suture Technique: Surgical Technique and Early Outcomes

BACKGROUND

Many surgical methods exist for distal biceps repair. We present the technique and early outcomes of a series of distal biceps repairs completed with a novel suturing technique utilizing a hemi-Krackow locking stitch at the tendon-bone interface.

METHODS

A retrospective review was performed of patients who underwent primary distal biceps repair using a single anterior incision with 2 suture anchors utilizing a hemi-Krackow stitch. With both anchors, a locking stitch along the tendon edge was complimented by the other strand passing through the central aspect of the distal tendon and advanced to pull the tendon edge down to the bone with appropriate tension. Patients with revision surgery and the use of allograft were excluded. Clinical outcomes included elbow range of motion and grip strength. All patients completed a Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire and reported satisfaction level, pain level, and any postoperative complications.

RESULTS

Fourteen patients with an average age of 51.3 years (range, 27.8-66.4 years) were included in the study. The dominant arm was injured in 9 cases. At an average of 16.4 months' follow-up (range, 6.8-34.3 months), all patients had elbow range of motion of 0° to >130°, and grip strength was 101.5% of the uninjured arm (range, 70.6%-121.4%). The Average QuickDASH score was 6.5 (range, 0-36.5).

CONCLUSION

Single incision biceps repair with suture anchor fixation using our hemi-Krackow stitch provided a strong repair allowing easy tensioning of the biceps tendon to bone and showed satisfactory functional outcomes at early follow-up. No patients required revision surgery, and there was only 1 case of transient nerve complaints.

Refixation techniques and approaches for distal biceps tendon ruptures: a systematic review of clinical studies

BACKGROUND

Surgical fixation is the preferred method of treatment for the ruptured distal biceps tendon in active patients. To date, no fixation technique has been proven superior in a clinical setting. The purpose of the study was to systematically review the available literature on approach and fixation methods for distal biceps tendon repair in a clinical setting and to determine the optimal fixation methods of the distal biceps tendon on the radial tuberosity. Our hypothesis was that the outcomes would not be significantly different among the various fixation techniques and approaches.

METHODS

A systematic review of the available literature on anatomic reconstruction methods for distal biceps tendon ruptures was performed. The outcome measures evaluated were postoperative range of motion, elbow flexion and supination strength, and complication rates and types.

RESULTS

Forty articles were included, representing 1074 patients divided into 4 fixation groups: suture anchors, bone tunnels, interference screws, and cortical buttons. There was no significant difference in range of motion and strength between the different approaches and fixation techniques. Complications were significantly less common after the double-incision approach with bone tunnel fixation (P < .0005).

CONCLUSIONS

There were significantly fewer complications after the double-incision approach with bone tunnel fixation. The double-incision approach had significantly fewer complications than the single-incision anterior approach, and the bone tunnel fixation had significantly fewer complications than the other 3 fixation techniques. However, as the double-incision approach was used with bone tunnel fixation in 84% of cases, there was a strong interrelationship between these variables.

Annular ligament reconstruction by suture anchor for treatment of radial head dislocation in children

BACKGROUND

We investigated the efficacy of annular ligament reconstruction by suture anchor in the treatment of radial head dislocation (RHD) in children.

METHOD

A total of 20 RHD children nderwent annular ligament reconstruction surgery using suture anchor. Preoperative and postoperative elbow functions were evaluated according to Broberg and Morrey 100-point scale. Recovery of radial nerve function was assessed using the Chinese Medical Association of Hand Surgery Branch of Upper Limb Functional Assessment Standard. All statistical analyses were performed using SPSS version 17.0 software.

RESULTS

All 20 RHD children who underwent the procedure were followed up for a median duration of 24 months. At the last follow-up, the average Broberg-Morrey score was 94.3, with 12 children (60.0%) showing excellent outcomes (score range, 95 to 100), 7 children (35.0%) showing good outcomes (score range, 80 to 94), 1 child (5.0%) displayed a fair outcome (score range, 60 to 79), and 0 (0%) poor outcome. A significant difference in the excellent-good rate was observed when the elbow function before surgery was compared to after surgery (χ(2)  = 5.559, P = 0.018). The radial nerve function of the 13 RHD children with radial nerve injury also recovered to normal. Among these 13 RHD children, nine exhibited excellent outcomes, 3 showed good outcomes, 1 displayed a fair outcome, and no patient showed a poor outcome. A significant difference in the excellent-good rate of radial nerve function was also observed when before surgery was compared to after surgery in these RHD children (χ(2)  = 4.887, P = 0.027).

CONCLUSION

Our results strongly indicated that suture anchor is highly effective for reconstruction of the annular ligament and to promote full functional recovery in RHD children, demonstrating that the procedure is an excellent treatment choice in RHD children.
