Three-dimensional measurement of proximal radioulnar space during active forearm pronation

Distal biceps tendon ruptures have been reported to be associated with narrowing of the proximal radioulnar space. There have been no studies that three-dimensionally measured the distance between the bicipital tuberosity and the proximal ulna during active motion. The purpose of this study was to three-dimensionally measure the proximal radioulnar space during active forearm pronation in healthy subjects. Five healthy volunteers (10 forearms) were recruited for this study. They consisted of all males with a mean age of 37 years (range, 34–46 years). Lateral fluoroscopy of forearm rotation from maximum supination to maximum pronation was recorded for both forearms. Three-dimensional forearm kinematics were determined using model-image registration techniques with fluoroscopic images and CT-derived bone models, and the closest distance between the bicipital tuberosity and the proximal ulna was computed at each 30° increment of radial axial rotation relative to the distal humerus. The distance between the bicipital tuberosity and the proximal ulna decreased with pronation, reaching a minimum value at 90° of radial rotation (average 4.6 ± 1.3 mm), then increased with further rotation to maximum pronation (P = 0.004). The clearance between the proximal radioulnar space and the distal biceps tendon is very small (<1mm). Hypertrophy of the bicipital tuberosity or tendon can induce impingement and lead to tendon rupture.

Surgical outcomes and complications following distal biceps tendon reconstruction: a systematic review and meta-analysis.

BackgroundPrimary repair of chronic distal biceps tendon ruptures may not be possible because of tendon retraction, and there remains no clear consensus on the type of reconstruction technique used. The purpose of this study was to report the clinical outcomes and complication rates following reconstruction of chronic distal biceps tendon ruptures.MethodsA systematic review was performed following PRISMA guidelines. The following databases were searched: Embase, MEDLINE, and Cochrane Central Register of Controlled Trials. The primary outcomes of interest included range of motion, strength, and functional outcome scores. Secondary outcomes included complication, reoperation, and revision rates. Outcomes and complication rates of each graft type and fixation technique were aggregated and compared with nonparametric Wilcoxon signed rank and rank sum tests. Spearman rank coefficients were calculated for time from injury to surgery on all outcomes.ResultsThere were no significant differences found between the graft type or fixation technique for postoperative range of motion, strength, and patient-reported outcomes. Postoperative complications were substantially higher in the autograft group (34%) as compared to the allograft group (14%). The fixation technique used also demonstrated a significantly increased complication rate in the weave group compared with the onlay group (34% and 9%, respectively).ConclusionOur results do not reveal any statistically significant differences between groups in the primary outcomes. However, substantially higher complication rates were observed in the autograft and weave cohorts; more than half of the complications related to the use of autograft were associated with donor site morbidity. No specific graft type was identified as superior, although this may be due to the small patient numbers included within this study.

Distal Biceps Tendon Rupture Surgery: Changing Incidence in Finnish and Swedish Men Between 1997 and 2016

Distal biceps tendon rupture is a relatively rare injury usually occurring with excess external extension force applied to a flexed elbow. The aim of this study was to examine the incidence of distal biceps tendon rupture surgery in the Finnish and Swedish adult population between the years 1997 and 2016. A secondary aim was to investigate the distal biceps rupture incidence in the Swedish population in 2001 to2016. We assessed the number and rate of distal biceps tendon rupture surgery using the Finnish and Swedish Hospital Discharge Register as databases. The study included the entire Finnish and Swedish adult population aged 18 years and older between January 1, 1997 and of December 31,2016. During the study period, 2,029 patients had a distal biceps tendon rupture in Finland, and the corresponding figure was 2,000 in Sweden. The rate of distal biceps tendon rupture surgery increased steeply, but equally, in both countries, in Finnish men from 1.3 per 100,000 person-years in 1997 to 9.6 in 2016, and in Swedish men from 0.2 in 1997 to 5.6 in 2016. The incidence of distal biceps tendon rupture in Sweden increased in men from 1.6 to 10.0 per 100,000 person-years from 2001 to2016. There was a 7-fold and a 28-fold increase in the incidence of distal biceps tendon rupture surgery in Finnish and Swedish men during 1997 to 2016. The incidence of distal biceps tendon rupture rose 6-fold in Swedish men in 2001 to2016. Prognostic IV.

Mini-Open Distal Biceps Tendon Repair Using All-Suture Anchors

Distal biceps tendon ruptures are uncommon injuries that can cause impairment in range of motion and function. While distal bicep tendon repair to the radial tuberosity has been demonstrated to restore function and strength, there is a lack of consensus on the optimal technique. The purpose of this Technical Note and video is to provide our preferred method of repair using an open, onlay-tissue fixation with all-suture anchors (FiberTak; Arthrex) and anatomic positioning of the biceps tendon on the radial tuberosity.

Diagnosis of Traumatic Biceps Brachii Tendon Injuries

The biceps muscle located between the shoulder and ulnar articulations is attached to the bone structures with a tendon, so in case of traumatic impact, the damage may be both in the proximal and distal parts. Most tendon ruptures occur in the proximal biceps, less often distally, in the area of radial tuberosity. The anamnesis and examination data play an important role in the diagnosis of ruptures. But the instrumental diagnostics is used for complete verification of the diagnosis and exclusion of complications or other diseases. The most reliable and comprehensive information is provided by the method of magnetic resonance imaging (MRI). The article presents analysis of MRI results in a patient with a complete distal biceps tendon rupture with the tendon pulled upward and the muscle retracted. The MRI study could make a correct clear diagnosis, which allowed the patient to immediately contact a specialized professional and to receive qualified assistance in time. Thus, it is shown that high-field MRI makes it possible to solve the problems of identifying the pathological processes and determining their severity with high accuracy.

Acute distal biceps tendon ruptures: anatomy, pathology and management - state of the art

All patients with acute complete distal biceps tendon ruptures who are not low demand or medically unfit to proceed with surgery are offered operative repair. This restores arm shape, supination strength and function, and decreases their cramping symptoms. Surgical repair technique varies significantly depending on location and training centre. Nuances in technique and appropriate implant selection need to be noted in order to achieve a strong repair allowing early active range of motion. Intimate knowledge of distal biceps tendon anatomy is key to avoid complications associated with the different approaches. The cumulative body of evidence on complications, coupled with knowledge of the different biomechanical construct strengths of the alternative methods of fixation, points to the use of the cortical button technique without the addition of an interference screw. Subtle variations in drill hole positioning on the bicipital tuberosity secures either an anatomic or non-anatomic repair. Anatomic repair results in greater supination peak torque and fatigue strength, and in greater flexion fatigue strength. It is advisable to perform an anatomic repair in elite athletes or those patients who significantly rely on supination strength and endurance for their livelihood. A universal postoperative protocol is suggested for all repairs.

Distal Biceps Tendon Repair Using a Modified Double-Incision Technique: Patient-Reported Outcomes With 10-Year Follow-up.

Background:In the setting of complete distal biceps tendon rupture, surgical repair has become the standard of care to restore optimal elbow function, but the optimal approach and method of tendon fixation are still subjects of debate and have remained controversial for more than half a century.Purpose:To evaluate patient-reported long-term outcomes after distal biceps tendon repair using a modified double-incision technique.Study Design:Case series; Level of evidence, 4.Methods:We reviewed primary distal biceps tendon repairs after isolated tendon rupture using the modified muscle-splitting double-incision approach and transosseous suture fixation technique described by Morrey et al (1985), which had been performed at our level 1 trauma center between January 2000 and December 2013. Outcome measures included the subjective elbow value (SEV), the Oxford Elbow Score (OES) with its 3 domains (function, pain, and social-psychological), a self-performed hook test, and the 3-level version of the EuroQoL 5-dimensional instrument (EQ-5D-3L) as a measure of health status. Levels of overall satisfaction were determined by asking whether the patient would consent to the operation again. In addition, patients were asked to report any complications.Results:A total of 30 patients met the inclusion criteria, and 25 patients were available for the survey. Mean age at the time of rupture was 47 years. All patients were male. Mean follow-up was 120 months (range, 57-207 months). The follow-up rate was 83.34%. The following outcome results were obtained: SEV, 88.16% ± 25.18%; OES, 43.80 ± 10.56 out of 48 points; OES Pain, 92.50% ± 23.03%; OES Function, 92.25% ± 22.19%; OES Social-Psychological, 89% ± 23.68%; EQ-5D-3L, 0.93 ± 0.21. All patients described a negative hook test. Patient-reported complications included painless limitation in forearm rotation in 8% of patients (n = 2); reduced flexion and forearm rotation strength with and without pain in 8% (n = 2) and 4% (n = 1), respectively; synostosis after 1 year requiring revision surgery in 4% (n = 1); and transient wrist drop in 4% (n = 1). The overall complication rate was 28% (7/25), and 96% (n = 24) would consent to the operation again.Conclusion:Despite the cited approach-related morbidity, we report an excellent patient-reported long-term outcome for the double-incision distal biceps repair technique.

Return to play and performance after surgical repair of distal biceps tendon ruptures in National Football League athletes

The purpose of this study was to determine whether surgical repair of distal biceps tendon ruptures in professional football players would lead to a decrease in postinjury performance when compared to preinjury performance and control-matched peers. We also sought to define return to sport, postinjury career length, and games played per season in National Football League players following surgical repair of distal biceps tendon ruptures. Data for National Football League players who underwent surgical repair of distal biceps tendon ruptures during a 20-year time period were collected. A total of 25 cases in 22 players were included in the analysis. Matched controls based on player position, age, experience, and performance statistics were identified. Performance scores for cases and controls were calculated using a standardized scoring system specific to player position. Of the 25 cases, 21 (84%) were able to return to sport in the National Football League. The overall 1-year survival rate of return to play in players undergoing surgical repair of distal biceps tendon ruptures was 76% and overall 2-year survival was 56%. Players who underwent surgical repair of distal biceps tendon ruptures had significantly shorter postinjury career lengths and played fewer games per season postinjury than matched controls. There was no significant difference by position in postinjury performance scores when compared to matched controls. National Football League players undergoing surgical repair of distal biceps tendon ruptures have a high rate of return to sport, though many retire within the next few seasons following surgery. Players who do return to competition can be expected to perform at a level comparable to their peers.

Partial rupture of the distal biceps brachii tendon: a magnetic resonance imaging analysis

This study is the largest cohort of partial distal biceps brachii tendon ruptures in the literature that was analyzed according to rupture morphology of the long and short tendon heads. Patients with partial distal biceps tendon ruptures were identified using an institutional enterprise data warehouse query at a single institution. A retrospective chart review was performed to record patient demographics, past medical history, and injury mechanism for each patient. Each patient's magnetic resonance images were reviewed to determine injury patterns, specifically the extent of long head (LH) and short head (SH) tendon involvement, and associated injuries. Rupture morphologies were correlated with mechanism of injury, diabetes status, and smoking history. Seventy-seven patients were included in the study. The average age was 52 years (±11.9, range: 23-90 years); 67% were male, with an average body mass index of 28.3 (±4.3). A smoking history was reported in 31.2% of patients and 5.2% were diabetic. The partial ruptures were caused by a traumatic mechanism in 57.1% of cases, 23.4% were atraumatic, and 19.5% had an unknown mechanism. The most common injury morphology was a partial LH rupture with an intact SH tendon (33.8%). Isolated complete ruptures of the LH represented the least common injury morphology. Injury morphology was significantly related to mechanism (P < .01). Traumatic ruptures had a higher percentage of SH involvement compared with the atraumatic group (77.3% vs. 37.7%, respectively). In contrast, atraumatic ruptures involved the LH tendon in 89% of cases, with only 37.7% of cases involving the SH tendon. Patients with a history of smoking were more likely to have an atraumatic mechanism (P = .01). A history of diabetes was unrelated to mechanism (P = .20). Partial ruptures of the distal biceps brachii tendon represent a spectrum of patterns with varying involvement of the LH and SH tendons. Injury morphology was significantly related to mechanism (P < .01). LH tendon involvement was seen in 88.9% of atraumatic cases, whereas SH tendon involvement was seen in 77.3% of traumatic cases. A more comprehensive understanding of partial rupture patterns is critical to further understand the risk factors that may preclude to worse clinical outcomes, and aid in deciding which patients would benefit from operative vs. nonoperative management.

Chronic distal biceps avulsion treated with suture button

Distal biceps tendon avulsions account for 3%-10% of all biceps ruptures. Treated nonoperatively, these injuries lead to a loss of endurance, supination strength, and flexion strength compared with operative repair or reconstruction. Operative management of chronic injury has classically been with graft tissue to augment the contracted muscle. We present our results for chronic distal biceps avulsions secured with suture button through a single transverse incision in high flexion without the need for allograft augmentation. This was a retrospective review of 20 patients with 21 injuries who underwent primary surgical repair of chronic distal biceps tendon avulsions at an average of 10 weeks (range 4-42 weeks). All patients were treated with a single transverse incision with a suture button armed with nonabsorbable no. 2 core sutures. Postoperatively patients were found to have 50°-90° flexion contracture. All patients were placed in a simple sling postoperatively with gentle extension to gravity as tolerated immediately and no formal physical therapy. Patients were surveyed regarding pre- and postoperative American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, visual analog scale (VAS) score, Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), and overall satisfaction. Range of motion (ROM), flexion, and supination strength compared to the contralateral uninjured extremity were evaluated at final follow-up. Mean clinical follow-up was 26 months. All patients regained full ROM and 5/5 flexion and supination strength at final follow-up. MEPSs were 100 for all responding patients compared with an average 47.5 preoperatively (P < .0001). The mean postoperative ASES score was 97.2 compared with 41.9 preoperatively (P < .0001). Mean OESs pre- and postoperatively were 24.2 and 48, respectively (P < .0001). The mean VAS score was 4.4 preoperatively and was reported as 0 by all patients at final follow-up (P < .0001). Two patients had transient sensory radial nerve neuropathy, and 1 patient has persistent palsy. No synostoses occurred. Four patients reported supination fatigue postoperatively compared with the uninjured extremity. Given these results, we feel that chronic distal biceps tendon ruptures can be repaired successfully with a single incision using suture button technique without the use of a graft. Though the flexion contracture is significant postoperatively, all patients regained full ROM and had excellent postoperative functional outcome scores.

A new intramedullary fixation method for distal biceps tendon ruptures: a biomechanical study

Various techniques have been described for distal biceps tendon reinsertion. Although high success rates have been reported, all current techniques have specific shortcomings, with complications such as heterotopic ossification, nerve damage, and gap formation. The purpose of the present study was to biomechanically evaluate a new intramedullary fixation device that might reduce the risk of posterior interosseous nerve lesions. We therefore compared the fixation strength of this new intramedullary button with an extramedullary placed classic extracortical button. A standard bicortical button was compared to the new intramedullary fixation device using fresh-frozen cadaveric specimens. The fixation strengths were tested both cyclically and statically. Load to failure and method of failure were also recorded. There were no failures during the cyclic load testing. The mean tendon-bone displacement was 0.87 ± 0.13 mm for the bicortical group and 0.83 ± 0.13 mm for the new button. During static loading, the mean load to failure for the bicortical group was 296 ± 97 N, whereas the new button group showed a higher mean load to failure of 356 ± 37 N. Breakout through the anterior cortex was recorded in 2 of 6 bicortically placed buttons and 1 of 6 in the new device. The new intramedullary fixation device yields comparable loads to failure compared with currently used techniques in a biomechanical setup. These findings together with the theoretical advantages suggest that this technique may be a valuable solution for the repair of distal biceps tendon rupture.

No functional differences in anatomic reconstruction with one vs. two suture anchors after non-simultaneous bilateral distal biceps brachii tendon rupture: a case report and review of the literature

BackgroundSurgical reattachment of the tendon is still the gold standard for ruptures of the distal biceps brachii tendon. Several fixation techniques have been described in the literature, with suture anchors being one of the most common fixation techniques. Currently, there is no data available on how many anchors are required for a safe and stable refixation. In this case report clinical data of a patient with non-simultaneous bilateral distal biceps tendon ruptures treated with a different number of suture anchors for each side (one vs. two) are demonstrated.Case presentationA 47-year-old factory worker suffered a rupture of the distal biceps tendon on both arms following two different occasions. The left side was fixed using a single suture anchor, while refixation on the right side was performed with two anchors.The patient was prospectively followed for one year. Functional outcome was assessed using the Andrews Carson Score (ACS), the Oxford Elbow Score (OES), and the Disabilities of Arm, Shoulder and Hand (DASH) Score after six, twelve, 24 and 48 weeks. Furthermore, an isokinetic strength measurement for flexion strength was performed after 24 and 48 weeks.After 48 weeks the patient presented with excellent functional outcome scores and no follow-up complications. During the follow-up period, no differences in the functional scores nor in the isokinetic flexion strength measurement could be detected. Furthermore, no radiological complications (like heterotopic ossifications) could be detected in the postoperative radiographs after one year.ConclusionsAnatomic reattachment of the distal biceps tendon is a successful operative treatment option for distal biceps tendon ruptures. Suture anchor fixation remains one of the most common techniques, as it allows fast surgery and provides good results with respect to range of motion (ROM) and functional scoring according to the current literature. However, the number of anchors required for a stable fixation remains unclear. As indicated by our presented case, we hypothesize, that there are no significant differences between a one-point or a two-point fixation. In the presented case report, no intraindividual differences between the usage of one versus two suture anchors were evident in the short-term follow-up.

Distal Biceps Tendon Repair Using a Double Tension Slide Technique

Distal biceps tendon ruptures are thought to be secondary to an acute forceful eccentric load on a degenerative tendon. Nonoperative treatment following rupture leads to significantly decreased forearm supination and elbow flexion strength. There are several techniques described in the literature for repair. This article describes, with video illustration, distal biceps tendon repair using a double tension slide technique with 2 No. 2 high-tension nonabsorbable composite sutures.

Primary repair of severely retracted nonchronic distal biceps tendon rupture using 2-incision anterior-approach repair

BackgroundPrimary repair of a severely retracted distal biceps tendon can pose a technical challenge. We sought to describe the method and clinical outcomes of a surgical technique used as an adjunct to the conventional anterior single-incision repair for severely retracted biceps tendons. This technique involves a second anterior incision proximally to retrieve a severely retracted tendon followed by passing the tendon through a soft-tissue tunnel.MethodsWe identified 30 consecutive patients who had undergone a primary distal biceps tendon repair by an anterior-approach cortical-button technique. A phone survey was conducted for patient-reported outcomes. Patients returned for bilateral forearm supination strength testing in 2 positions (45º of pronation and 45º of supination). Outcomes were compared between patients who required a second incision and high elbow flexion (>60º) because of severe tendon retraction and those who did not require such interventions.ResultsNo significant differences in elbow range of motion, supination strength, or patient-reported outcomes were found between the 2 groups of patients (P > .05). Regarding supination strength, the operated side was significantly weaker than the uninjured side in both pronated and supinated positions (P < .05). Both the operated and uninjured sides showed significantly higher torque in a pronated position than in a supinated position (P < .05).ConclusionsSeverely retracted distal biceps tendons can be successfully repaired using a second incision and high elbow flexion without negative effects on the outcomes. Supination strength was decreased following an anterior-approach cortical-button technique, but patient-reported outcomes were not affected negatively.

Pressure Distribution to the Distal Biceps Tendon at the Radial Tuberosity: A Biomechanical Study

Mechanical impingement at the narrow radioulnar space of the tuberosity is believed to be an etiological factor in the injury of the distal biceps tendon. The aim of the study was to compare the pressure distribution at the proximal radioulnar space between 2 fixation techniques and the intact state. Six right arms and 6 left arms from 5 female and 6 male frozen specimens were used for this study. A pressure transducer was introduced at the height of the radial tuberosity with the intact distal biceps tendon and after 2 fixation methods: the suture-anchor and the cortical button technique. The force (N), maximum pressure (kPa) applied to the radial tuberosity, and the contact area (mm2) of the radial tuberosity with the ulna were measured and differences from the intact tendon were detected from 60° supination to 60° pronation in 15° increments with the elbow in full extension and in 45° and 90° flexion of the elbow. With the distal biceps tendon intact, the pressures during pronation were similar regardless of extension and flexion and were the highest at 60° pronation with 90° elbow flexion (23.3 ± 53.5 kPa). After repair of the tendon, the mean peak pressure, contact area, and total force showed an increase regardless of the fixation technique. Highest peak pressures were found using the cortical button technique at 45° flexion of the elbow and 60° pronation. These differences were significantly different from the intact tendon. The contact area was significantly larger in full extension and 15°, 30°, and 60° pronation using the cortical button technique. Pressures on the distal biceps tendon at the radial tuberosity increase during pronation, especially after repair of the tendon. Mechanical impingement could play a role in both the etiology of primary distal biceps tendon ruptures and the complications occurring after fixation of the tendon using certain techniques.

Distal biceps tendon rupture: diagnostic strength of ultrasonography and magnetic resonance

Objectivethe main purpose of this study is to determine the agreement between two radiological tests, ultrasonography and magnetic resonance, in the diagnosis of distal brachial biceps tendon injury. Material and methodA retrospective study was made of patients over 3 years who underwent distal brachial biceps tendon reattachment open surgery, and whose preoperative diagnosis was complemented either by ultrasonography, by magnetic resonance or both. The agreement was calculated by Cohen’s kappa coefficient (k). Resultsinformation of 79 patients was analyzed. The concordance was excellent between resonance and surgical findings (k=.950), and a good Cohen´s kappa coefficient was also achieved between both ultrasonography and surgery (k=.706) and between information of sonography and magnetic resonance (k=0.667). ConclusionsResonance and ultrasonography could be considered reliable diagnostic tests to determine the acute rupture of the distal brachial biceps tendon in patients with consistent aetiology and physical examination.

P712 When Popeye had shortness of breath

Abstract A 61-year-old man presented to our clinic with progressive shortness-of-breath in the last 3 months. He had a history of hospitalization and endotracheal intubation due to acute pulmonary edema and type – I respiratory failure a week ago and discharged after diagnostic coronary angiography which demonstrating normal coronary arteries. Physical examination revealed bunching of the left biceps when he flexed his left arm which is consistent with rupture of distal biceps tendon (Panel A, Popeye Sign). A 12-lead electrocardiography (ECG) showed low QRS voltage in the limb leads and ST segment depression and asymmetrical T wave inversion in the anterolateral leads (Panel B). Transthoracic echocardiography (TTE) showed concentric left ventricular hypertrophy with left ventricular ejection fraction of 60% (Panel C). Pulsed wave-Doppler obtained from the mitral valve demonstrated restrictive filling pattern with high early diastolic velocity (E-wave) and low late diastolic filling (A-wave) peaks with E/A ratio &amp;gt; 2.0 and reduced lateral mitral annular diastolic velocities with E/e’ ratio &amp;gt; 15 which are compatible with impaired left ventricular diastolic function with elevated left ventricular filling pressures (Panel D-E). Biceps tendon rupture, low QRS voltage and left ventricular hypertrophy with restrictive filling pattern were considered suggestive of cardiac amyloidosis and patient was referred to hematology clinic for diagnostic work-up. Protein electrophoresis demonstrated monoclonal gammopathy in the serum and immunoelectrophoresis showed free lambda light chains. The patient diagnosed as AL amyloidosis with cardiac and musculoskeletal involvement. Biceps tendon rupture is a rare finding of amyloidosis due to musculoskeletal involvement. In the setting of acute pulmonary edema and/or heart failure with preserved ejection fraction with massive left ventricular hypertrophy, restrictive filling pattern, low QRS voltage and spontaneous tendon rupture should raise clinical suspicion of amyloidosis with cardiac and musculoskeletal involvement. Abstract P712 Figure.

Reinsertion of distal biceps ruptures with a single anterior approach: analysis of 14 cases using tension-slide technique and interference screw.

Background:Several techniques of surgical repair of biceps tendon ruptures are described in literature. Cortical button repair have shown minimal loss of elbow flexion, supination and strength. In this retrospective study we report the outcomes in terms of elbow function and complications of tension-slide technique and interference screw.Matherials and methods:14 patients with complete distal biceps tendon rupture were included in the retrospective study and treated with the same tension-slide technique (BicepsButton® - Arthrex, Inc, Naples, Florida) evaluating the clinical and functional outcomes and the complication rate with a follow-up average of 18 months.Results:The flexion recovered compare to the healthy contralateral was 96% (min 115° - max 135°; average 128°), the extension was 97% (min: -2° - max 15°; average 4°), the supination was 90% (min 20° - max 90°; average 75°), the pronation was 95% (min 15° - max 90°; average 76°). The mean Disabilities of Arm, Shoulder and Hand (DASH) score was 8.1 ± 10.5 and Mayo Elbow Performance Score overall (MEPS) score was 97.6 ± 8.2. Two patients had LABCN paresthesia, one case, treated 2 months after injury, had posterior interosseus nerve palsy. One patient had heterotopic ossification at the radiological examination without consequences for the clinical performances. No case of non-traumatic tendon re-rupture and no case of ROM deficiency > 20%. In all case the cortical button remains well positioned and no case of osteolysis were reported.Conclusions:Distal biceps tendon repair with BicepsButton® system seems to be a safe, relyable and reproducible technique providing excellent clinical, functional and radiological outcomes. Comparing with other techniques the BicepsButton® system has the advantages of the single approach procedures, the reduction of surgical time and risk of heterotopic ossifications.
