Results of primary repair of distal triceps tendon ruptures in a general population: a multicentre study

Augmentation of triceps tendon repair with a bio-inductive collagen scaffold

Two active, adult male patients, one with prior triceps rupture and direct repair, presented with traumatic rupture of the distal triceps tendon. MRI confirmed not only complete rupture with retraction in both, but also signal changes within the tendon, raising concern for healing potential and re-rupture. Surgical repair was performed using heavy, non-absorbable suture and suture anchors in the standard fashion, followed by augmentation with a bovine, bio-inductive collagen scaffold in order to increase tendon thickness and aid with healing capability. This technique is well described for rotator cuff repair augmentation but is a novel technique to the literature in the setting of triceps tendons repair. Both patients returned to full, preinjury activity without complication with sustained results at 3 and 3.5 years postoperatively.

The Elbow's Achilles Heel: A Systematic Review and Meta-Analysis of Triceps Tendon Rupture and Repair Techniques

Triceps tendon avulsion is a rare but debilitating condition and the least frequent of all tendon injuries, but it is receiving increasing attention in the literature. The most common mechanism of injury is resisted extension, which is typically seen in a fall onto an extended hand. Such injuries are easily overlooked and should be considered a differential diagnosis in all patients who describe pain and swelling at the posterior aspect of the elbow following a traumatic event. Non-operative management is the general principle for partial rupture as opposed to a variety of surgical treatments for a complete avulsion. The goal of this meta-analysis is to analyse the current literature on triceps avulsion and provide a detailed overview of the occurrence, diagnosis, treatment options and outcomes, comparison of various repair techniques, and consequences of this injury.

[Surgical treatment of distal triceps tendon ruptures]

OBJECTIVE

Restoration of the anatomy and the original length of the muscle-tendon unit in triceps tendon ruptures.

INDICATIONS

Acute and chronic triceps tendon ruptures with persisting symptoms and significant strength deficits.

CONTRAINDICATIONS

Infections and tumors in the surgical area.

SURGICAL TECHNIQUE

Prone position. Skin incision over the distal triceps in a lateral direction around the olecranon. Mobilization of the tendon and débridement of the olecranon. Drilling of 2 × 2.9 mm suture anchor holes medial and lateral into the footprint of the olecranon. In addition, drilling through the olecranon 12 mm distal to the tip of the olecranon and transosseous introduction of 4 sutures. Then the suture anchors (all-suture or titanium anchors) are inserted into the drill holes. Refix the deep and superficial tendons with the anchor threads. Refix the upper tendon portions with the transosseous sutures. In the case of chronic lesions, a graft interposition is necessary.

POSTOPERATIVE MANAGEMENT

Dorsal 10 ° splint, then change to an orthosis fixed in 20 ° extension and passive mobility 0-30 ° flexion for 6 weeks. From the 7th week onwards, load-free, physiotherapeutically controlled increasing mobilization. Starting weight-loading from the 13th week on. Full load after 6 months.

RESULTS

In all, 34 male strength athletes with acute triceps tendon rupture underwent surgery using the hybrid technique described and were prospectively recorded. The MEPS‑G score averaged 94.7 points, there were no permanent limitations in mobility, and the postoperative strength ability averaged 94% of the original strength performance ability. The return to sport achieved 100%. The complication rate was 20.6%. Reconstruction of the distal triceps tendon using hybrid technology leads to very good functional results. Half of all patients complained of symptoms even before the rupture, which suggests previous damage to the distal triceps tendon caused by degeneration.

Complications after traumatic distal triceps tears: an analysis of 107 cases

Background

The major complication and reoperation rates after distal triceps repair are poorly defined. The purpose of this large retrospective cohort study of distal triceps repairs performed by multiple surgeons within a large orthopedic group was to more clearly define the rates and risk factors of clinically impactful major complications and reoperations.

Methods

All distal triceps tendon repairs for traumatic injuries performed from January 2006 to April 2017 with a minimum 2-month follow-up were identified using the Current Procedural Terminology code 24342. A total of 107 patients were included in this study. The primary outcome measure was total major complication rate. Reoperations, minor complications, and risk factors were also tracked.

Results

Repairs were performed via bone tunnels (63.5%), suture anchors (13%), or a combination of the two (17.8%). A 14% complication rate and 13.1% reoperation rate were observed. Indication for reoperation included 9 reruptures, 3 infections, and 2 others. The time between injury and surgery was not found to be a risk factor for tendon rerupture. Smoking status, gender, utilization of a splint or controlled motion brace, and time to first active mobilization were not shown to influence rates or rerupture.

Conclusion

Distal triceps repair for traumatic injuries is associated with 14% complication and 13.1% reoperation rates. Patient, rehabilitation, and surgeon-specific factors did not influence the complication rate.

Surgical repair of distal triceps rupture: a systematic review of outcomes and complications

Background

Triceps tendon injury is rare and accounts for only 2% of all tendinous injuries. It typically occurs after trauma or physical strain with eccentric loading. Treatment involves surgical repair, commonly with either transosseous bone tunnels or suture anchors. Nonsurgical management is typically reserved for low-demand or high-risk patients, as this is associated with deficits in strength and functional disability. Despite several recent high-quality observational studies that have added to our understanding of outcomes after surgical repair, we are not aware of a systematic review that includes literature published after 2015. In addition, prior reviews did not compare outcomes between different surgical repair methods, particularly transosseous bone tunnel and suture anchor techniques.

Methods

This systematic review examines published literature between January 1970 and May 2021 in PubMed, Scopus, and Cochrane databases to further examine reported functional outcomes and compare those outcomes between the two surgical repair methods.

Results

Our literature search yielded 309 results, of which only 16 met inclusion criteria. At the latest follow-up, the mean Disabilities of Arm, Shoulder, and Hand score was 4, the mean Quick Disabilities of Arm, Shoulder, and Hand score was 8, the mean Mayo Elbow Performance Score was 92, the mean American Shoulder and Elbow Surgeons-Elbow score was 99, the mean modified American Shoulder and Elbow Surgeons score was 94, the mean Oxford Elbow Score was 43, and the mean isokinetic muscle strength testing was 87%. A very high percentage (95%) of patients reported being satisfied with the repair. Preinjury levels of function were achieved in 92% of patients, and 100% regained at least a score of 4 of 5 for gross muscle strength. Complications occurred in 15% of cases, of which retears accounted for 5%. Subanalysis of cases with reported repair types revealed a significantly higher overall complication rate with transosseous repairs than with suture anchor repairs (18% vs. 8%, P = .008) as well as a higher retear rate in the transosseous repair group (7% vs. 2%, P = .03).

Conclusion

Patient-reported outcome measures were favorable for both suture anchor and transosseous tunnel repair methods. Suture anchor repair showed significantly better results with regard to isokinetic strength testing, complication rates, and retear rates. Further study is needed to establish superiority of either technique and cost-efficacy. In light of the evidence supporting greater biomechanical strength and lower clinical rates of failure, surgeons may consider use of a suture anchor technique for repair of distal triceps ruptures.

Distal Triceps Tendon Tears: Magnetic Resonance Imaging Patterns Using a Systematic Classification

OBJECTIVE

This study aimed to evaluate distal triceps tendon tear patterns using a systematic classification based on the tendon's layered structure.

METHODS

We retrospectively identified Magnetic resonance imaging (MRI) examinations with triceps tendon tears that underwent reconstructive surgery. Magnetic resonance images were reviewed independently by 2 musculoskeletal radiologists to determine tendon layer involvement and ancillary findings, including tear size, involvement of triceps lateral expansion, and presence of olecranon bursal fluid. Surgical reports were scrutinized for level of anatomic detail and correlation with imaging findings.

RESULTS

We identified 69 triceps tendon tears in 68 subjects (61 men, 7 women; mean age, 45 ± 12 years) who underwent surgical reconstruction. On MRI, the superficial layer was always involved with either a partial or full-thickness tear. The most common tear pattern was a combination of superficial layer full-thickness tear with deep layer partial tear (25 of 69 [36%]). Mean tear length was 24 ± 12 mm. We found no cases of isolated deep layer tears. Involvement of triceps lateral expansion and presence of bursal fluid correlated positively with tear severity of superficial and deep layers (P < 0.001). Detailed surgical correlation was limited, with only 9 of 69 (13%) of surgical reports containing information specifically addressing individual tendon layers.

CONCLUSIONS

Triceps tendon tears show tear patterns following its layered structure and can be assessed by MRI. Radiologists and surgeons are encouraged to describe tear patterns considering both superficial and deep tendon layers.

The surgical management of distal triceps tendon ruptures: a systematic review

BACKGROUND

Distal triceps tendon ruptures (DTTRs) are highly uncommon injuries and can be treated with surgical repair. The purpose of this review was to compare the outcomes and complications of various surgical techniques used for primary repair of DTTRs.

METHODS

The electronic databases MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and PubMed were searched from data inception to October 15, 2020. The Methodological Index for Non-randomized Studies tool was used to assess study quality. Data are presented descriptively.

RESULTS

A total of 19 studies were identified, comprising 560 patients (565 triceps tendons), of whom 78.6% were male patients. The mean age was 46.1 ± 8.4 years, and the mean follow-up period was 31.8 ± 21.0 months. The overall complication rate across all DTTR repair procedures was 14.9%. The distribution of complications for each technique was 29.2% for the direct repair technique, 15.2% for the transosseous technique (transosseous suture), and 7.7% for the suture anchor technique. Common complications include ulnar neuropathies, infections, and pain. The overall rerupture rate for transosseous suture, suture anchor, and direct repair was 4.3% (n = 12), 2.1% (n = 3), and 0% (n = 0), respectively. Patients undergoing DTTR repair experience significant improvements postoperatively regarding pain, strength, and range of motion.

CONCLUSIONS

Patients undergoing DTTR experience improvements in postoperative outcomes; however, there is a moderate reported risk of rerupture or complication. Owing to the heterogeneity in rupture patterns, surgical procedures, and outcome measures, it is difficult to ascertain the superiority of one surgical technique over another. Future studies should use large prospective cohorts and long-term follow-up to determine more accurate complication rates and outcome scores.

[Lesions of the triceps tendon : Diagnostics, management, treatment]

The triceps brachii muscle is the main extender of the elbow joint. Triceps tendon rupture or tearing presents a rare injury pattern in general. Distal tendon ruptures occur most commonly in the area of the insertion of the olecranon. Fractures of the radial head are reported as the most common concomitant injury. In many cases, pre-existing degenerative damage predisposes for tendon injury. These include local steroid injections, anabolic steroid abuse, renal insufficiency requiring dialysis, hyperparathyroidism, lupus erythematosus and Marfan's syndrome. However, the most frequent trauma mechanism is a direct fall onto the extended forearm or a blow to the elbow. Beside clinical examination and sonography, magnetic resonance imaging is the diagnostic gold standard. The treatment of triceps tendon injuries includes conservative as well as operative approaches, whereby the indications for surgical treatment must be generously considered depending on the patient's age, functional demands of the patient, involvement of the dominant extremity as well as on the extent of the tendon rupture.

Triceps Rupture and Repair in a Healthy, Young Woman following Rock Climbing

Triceps tendon rupture in females is rare. In this case report, we present a young adult female patient with a distal triceps tendon rupture from bouldering treated with open surgical repair technique using a modified bone tunnel and suture anchor fixation technique. The diagnosis and technique for repair and postoperative rehabilitation are described. A review of the current literature of biomechanical and clinical outcomes of various repair techniques is also presented.

A clinicoradiological classification and a treatment algorithm for traumatic triceps tendon avulsion in adults

PURPOSE

Triceps tendon avulsion (TTA) is an uncommon injury, and there are no classifications or treatment guidelines available. This study aims to describe a clinicoradiological classification and treatment algorithm for traumatic TTA in adults. The functional outcome of surgical repair has been evaluated too.

METHODS

A retrospective analysis of adult patients with traumatic TTA treated in our institution between January 2012 and December 2017 was done. We only included complete TTA injuries. Children below 15 years, with open injuries, associated fractures, or partial TTA were excluded. The data were obtained from hospital records. The intraoperative findings were correlated with the clinicoradiological presentation for classifying TTA. The functional outcome was analyzed using the Mayo Elbow Performance index and Hospital for Special Surgery elbow score. ANOVA test was used to assess the statistical significance.

RESULTS

There were 15 patients included, 11 males and 4 females. The mean age was (31.5 ± 9.15) years, and the mean follow-up was (22.4 ± 8.4) months. Fall on outstretched hand was the mode of injury. In 6 patients, diagnosis was missed on the initial visit. TTA were classified as Type I: palpable soft-tissue defect without bony mass; Type II: palpable soft-tissue defect with a wafer-thin/comminuted bony fragment on X-ray; Type III: palpable soft-tissue defect with a bony mass and a large bony fragment on X-ray without extension to the articular surface; and Type IV: an olecranon fracture with less than 25% of the articular surface. An algorithm for treatment was recommended, i.e. transosseous suture repair/suture anchor for Type I, transosseous suture repair for Type II, and tension band wiring or steel wire sutures for Types III and IV. All the patients achieved good to excellent outcome: the mean Mayo Elbow Performance index was 100 and Hospital for Special Surgery score was 98.26 ± 2.60 on final follow-up.

CONCLUSION

Our clinicoradiological classification and treatment algorithm for TTAs is simple. Surgical treatment results in excellent functions of the elbow. Since it is a single-center study involving a very small number of cases, a multicenter study with a larger number of patients is required for external validation of our classification and treatment recommendations.

A unique case of bilateral triceps avulsion fracture in a patient with pseudohypoparathyroidism

Triceps tendon ruptures and avulsions are rare injuries and are often associated with systemic diseases. This paper illustrates the unique case of a 20-year-old female patient with pseudohypoparathyroidism, who sustained bilateral triceps avulsion fractures after a fall. She underwent suture anchor fixation, augmented with tension band suture as double row repair with excellent post-operative results. We describe the pathophysiology of this injury and the unique method of fixation, which can be an alternative effective method to repair these injuries.

Differences in Rupture Patterns and Associated Lesions Related to Traumatic Distal Triceps Tendon Rupture Between Outstretched Hand and Direct Injuries

BACKGROUND

Traumatic distal triceps tendon rupture results in substantial disability in the absence of an appropriate diagnosis and treatment. To the best of our knowledge, differences in the degree of injury according to the injury mechanisms and associated lesions are not well known.

QUESTIONS/PURPOSES

In this study, we asked: (1) What differences are seen in triceps tear patterns between indirect injuries (fall on an outstretched hand) and direct injuries? (2) What are the associated elbow and soft tissue injuries seen in indirect and direct triceps ruptures?

METHODS

Between 2006 and 2017, one center treated 73 elbows of 72 patients for distal triceps tendon rupture. Of those, 70% (51 of 73 elbows) was excluded from this study; 8% (6 of 73) were related to systemic diseases, 59% (43 of 73) sustained open injuries, and 3% (2 of 73) were related to local steroid injections. We retrospectively collected data on traumatic distal triceps tendon rupture in 30% (22 of 73) of elbows at a single trauma center during a 10-year period. A fall on an outstretched hand was the cause of injury in 15 patients and direct blow by object or contusion were the cause in seven. MRI and surgery were performed in all patients. Traumatic distal triceps tendon rupture was classified by the Giannicola method, which is classified according to the depth and degree of the lesion based on MRI and surgical findings. Associated fractures and bone contusions on MRI were characterized. Ligament injuries on MRI was divided into partial and complete rupture. Agreement between the MRI and intraoperative findings for the presence of a traumatic distal triceps tendon rupture was perfect, and the Giannicola classification of traumatic distal triceps tendon rupture was good (kappa = 0.713).

RESULTS

In the indirect injury group (fall on an outstretched hand), 15 of 15 patients had injuries that involved only the tendinous portion of the distal triceps, but these injuries were not full-thickness tears, whereas in the direct injury group, three of seven patients had a full-thickness rupture (odds ratio [OR] 1.75 [95% CI 0.92 to 3.32]; p = 0.02). The direct injury group had no associated ligamentous injuries while 14 of 15 patients with indirect injuries had ligamentous injuries (OR 0.13 [95% CI 0.02 to 0.78]; p < 0.001; associated injuries in the indirect group: anterior medial collateral ligament [14 of 15], posterior medial collateral ligament [7 of 15], and lateral collateral ligament complex [2 of 15]). Similarly, one of seven patients in the direct injury group had a bone injury (capitellar contusion), whereas 15 of 15 patients with indirect ruptures had associated fractures or bone contusions (OR 16.0 [95% CI 2.4 to 106.7]; p < 0.001).

CONCLUSION

A fall on an outstretched hand may result in an injury mostly to the lateral and long head of distal triceps tendon and an intact medial head tendon; however, direct injuries can involve full-thickness ruptures. Although a traumatic distal triceps tendon rupture occurs after a fall on an outstretched hand, radial neck, capitellar, and medial collateral ligament injury can occur because of valgus load and remnant extensor mechanisms. Based on our finding, the clinician encountering a distal triceps tendon rupture due to a fall on an outstretched hand should be aware of the possibility of remaining elbow extensor mechanism by intact medial head tendon portion, and associated injuries, which may induce latent complications.

Arthroscopic superior capsular reconstruction of the shoulder: a narrative review

Irreparable rotator cuff tears (IRCTs) in young and considerably active patients are difficult to treat because it is mostly associated with poor outcome which may lead to a painful and dysfunctional shoulder. Most of the IRCTs are encountered in massive size rotator cuff tears which associated with high failure rate following surgical repair. Thus, the IRCTs was considered challenging for its poor healing rate following repair which may induce the arthritic changes. Since the advent of arthroscopic superior capsular reconstruction (ASCR) of the shoulder in 2013, it has gained its popularity. The procedure has become the most popular option for joint-preserving shoulder surgery for patients with IRCTs. It works by providing a static restraint to the superior humeral head migration to optimize the rotator cuff force couples, hence improving joint kinematics. The acceptance of superior capsular reconstruction has made it rapidly evolving in terms of a wider variety of procedures and broader surgical indications. Despite the enthusiasm and widely acceptance towards the procedure, there are still many queries that exist regarding the best indications, surgical technique particularly graft of choice, the long-term outcome, and the complication and risk of the superior capsular reconstruction (SCR). This narrative review provide the current evidence of SCR in an attempt to provide a state-of-the-art knowledge.

Triceps Tendon Injuries

Triceps tendon injuries are an uncommon clinical entity poorly described in the literature. This review discusses the spectrum of pathology, effective diagnosis, nonsurgical treatment, surgical treatment, rehabilitation, and surgical complications of triceps tendon injuries. Management of triceps tendinopathies depends on the mechanism of injury and the patient's motor examination. Triceps tendinopathies and partial tendon tears with intact strength can be managed conservatively with rest, ice, immobilization, nonsteroidal anti-inflammatory drugs, and physical therapy. If conservative management fails for 6 months or there are strength deficits on examination, surgery should be considered. Based on the current evidence, there are no clear guidelines for "best" surgical approach. Although rare, the most significant surgical complication to be concerned about is rerupture. Rerupture rate is 4.62% among the articles we reviewed.

Triceps Tendon Ruptures: Risk Factors, Treatment, and Rehabilitation

Triceps tendon ruptures (TTRs) are rare and often occur as a result of falling on an outstretched hand, forceful eccentric contraction, direct trauma to the elbow, or lifting against resistance. TTRs are most commonly seen in middle-aged men, football players, and weightlifters. Radiography, ultrasonography, and magnetic resonance imaging may be utilized for diagnosis and to guide treatment. Acute partial TTRs may have good outcomes with nonoperative management. Surgery should be considered if nonoperative treatment is unsuccessful or if substantial musculotendinous retraction is present. Surgical repair is strongly recommended for complete TTRs.

Surgical Repair of Distal Triceps Tendon Injuries: Short-term to Midterm Clinical Outcomes and Risk Factors for Perioperative Complications

Background

Few large-scale series have described functional outcomes after distal triceps tendon repair. Predictors for operative success and a comparative analysis of surgical techniques are limited in the reported literature.

Purpose

To evaluate short-term to midterm functional outcomes after distal triceps tendon repair in a broad patient population and to comparatively evaluate patient-reported outcomes in patients with and without pre-existing olecranon enthesopathy while also assessing for modifiable risk factors associated with adverse patient outcomes and/or revision surgery.

Study Design

Case series; Level of evidence, 4.

Methods

This study was a retrospective analysis of 69 consecutive patients who underwent surgical repair of distal triceps tendon injuries at a single institution. Demographic information, time from injury to surgery, mechanism of injury, extent of the tear, pre-existing enthesopathy, perioperative complications, and validated patient-reported outcome scores were included in the analysis. Patients with a minimum of 1-year follow-up were included.

Results

The most common mechanisms of injury were direct elbow trauma (44.9%), extension/lifting exercises (20.3%), overuse (17.4%), and hyperflexion or hyperextension (17.4%). Eighteen patients were identified with pre-existing symptomatic enthesopathy, and 51 tears were caused by an acute injury. A total of 36 complete and 33 partial tendon tears were identified. Bone tunnels were most commonly used (n = 30; 43.5%), while direct sutures (n = 23; 33.3%) and suture anchors (n = 13; 18.8%) were also used. Perioperative complications occurred in 21.7% of patients, but no patients experienced a rerupture at the time of final follow-up. No statistically significant relationship was found between patient age (P = .750), degree of the tear (P = .613), or surgical technique employed (P = .608) and the presence of perioperative complications.

Conclusion

Despite the heightened risk of perioperative complications after primary repair of distal triceps tendon injuries, the current series found favorable functional outcomes and no cases of reruptures at short-term to midterm follow-up. Furthermore, age, surgical technique, extent of the tear, and mechanism of injury were not associated with adverse patient outcomes in this investigation. Pre-existing triceps enthesopathy was shown to be associated with increased complication rates.

Distal Triceps Rupture Repair: The Triceps Pulley-Pullover Technique

Distal triceps rupture is an uncommon but debilitating injury, and surgical fixation is almost invariably warranted. A number of techniques have been described in the literature in which combinations of transosseous tunnels and bone anchors have been used. We describe a modification to existing techniques-the triceps pulley-pullover technique with all-suture anchors. This technique minimizes bone loss, while maximizing the bone-tendon contact area and creating a double-row repair to optimize strength and healing.
