Distal triceps injuries (including snapping triceps): A systematic review of the literature

Rehabilitation following distal triceps repair: A scoping review

BACKGROUND

Distal triceps ruptures are relatively rare injuries where surgical repair is recommended for return to function and sport. There are various fixation techniques and different therapy protocols described in the literature.

PURPOSE

To scope and critically evaluate current knowledge of post-operative protocols and complications following repair and extrapolate tendon healing principles to clinical practice.

STUDY DESIGN

Scoping review.

METHODS

The Joanna Briggs Institute framework for Scoping Reviews was followed, and specific inclusion/exclusion criteria were applied to identify high-quality, relevant evidence. Studies were included if they met the following criteria: written in English, focused on adults over 17 years of age with complete distal triceps tendon ruptures, and published as peer-reviewed articles, conference abstracts, university dissertations, or theses. Additionally, the studies had to use at least one validated outcome measure. Electronic and manual searches were completed of published and gray literature. Quantitative sources were included for complete triceps ruptures that measured outcomes using at least one validated outcome measure. Qualitative sources that were published within 10 years from a reputable journal were included for qualitative synthesis.

RESULTS

Eighteen quantitative articles consisting of case series and systematic reviews, and 16 expert opinion and narrative reviews met the inclusion criteria. There was no standardized postoperative protocol with differences found in timing for ranging, strengthening, and return to function. The most reported complications were tendon rerupture, infection, pain, and ulnar nerve neuropathy.

CONCLUSIONS

What is known about triceps tendon repairs comes from low level evidence. Randomized controlled trials are required to evaluate the effect of surgical constructs and therapy on function. The protocols identified in this scoping review typically progressed through several stages, starting with complete immobilization and moving on to ranging, strengthening, and finally returning to sport and functional activities. Therapists can apply general tendon healing principles when rehabilitating these patients and should be aware of modifiers to healing timeframes when making decisions on strengthening and resuming activities that require high function.

Distal Triceps Tendon Ruptures: A Case Series Highlighting Diagnostic Challenges, Surgical Management, and Functional Outcomes

Triceps tendon ruptures are uncommon but significant injuries, often presenting diagnostic challenges due to nonspecific clinical features. Delayed or missed diagnoses can result in prolonged functional impairment. We present a retrospective case series of five patients who sustained distal triceps tendon ruptures through various mechanisms, including direct trauma and heavy lifting. Clinical presentations ranged from elbow swelling and pain to palpable tendon gaps, with radiographic "flake signs" consistently observed. Ultrasonography effectively identified tendon ruptures and retraction in four cases, reinforcing its diagnostic value. All patients underwent surgical repair using suture anchor techniques, achieving satisfactory outcomes. This case series emphasises the importance of early recognition, timely imaging, and prompt surgical intervention in managing distal triceps tendon ruptures to optimise patient recovery.

Failed ulnar nerve surgery due to persistent unrecognized snapping triceps from cubitus varus due to a distal humeral malunion in an adult: illustrative case

BACKGROUND

Snapping triceps is a dynamic condition in which a portion of the medial head of the triceps dislocates over the medial epicondyle during flexion or extension. Pushed by the triceps, the ulnar nerve typically also dislocates over the medial epicondyle, causing neuropathy. Posttraumatic cubitus varus deformities resulting from pediatric supracondylar fractures have been associated with snapping triceps. This is the first case of snapping triceps associated with cubitus varus due to distal humeral malunion, which occurred in an adult.

OBSERVATIONS

A 23-year-old man sustained a left distal humeral fracture from arm wrestling, which was treated nonoperatively, healing in a varus malunion. Within several months, he developed ulnar neuropathy and snapping at the medial elbow, which was diagnosed as a dislocating ulnar nerve and was treated with ulnar nerve transposition. He presented 8 years later with continued ulnar neuritis symptoms and snapping and was found to have snapping medial triceps. He chose nonoperative treatment.

LESSONS

Snapping triceps, presenting as snapping at the elbow with ulnar nerve symptoms, can be incorrectly diagnosed as isolated ulnar nerve dislocation. Unrecognized snapping triceps leads to persistent symptoms after ulnar nerve transposition. The patient in this case demonstrated that an altered triceps line of pull can cause snapping triceps regardless of how the cubitus varus originated. https://thejns.org/doi/10.3171/CASE24596.

Avulsion fracture of olecranon treated with McLaughlin-cerclage using an artificial ligament: a case report

A 65-year-old woman presented with right elbow pain after a fall. Imaging showed an avulsion fracture of the olecranon. The patient subsequently underwent surgery using the suture bridge technique with anchors. However, loosening was observed intraoperatively. Therefore, a McLaughlin cerclage with an artificial ligament was added, resulting in a rigid fixation. Bone union was achieved at 4 months postoperatively. At 18 months postoperatively, no limitation was observed in the range of motion of the elbow joint; the disabilities of the arm, shoulder and hand score was 0. McLaughlin cerclage with an artificial ligament provided additional fixation, demonstrating greater strength compared with suture anchors and minimizing the risk of cut-through in the osteoporotic bone. This approach offers a promising alternative for such cases by combining firm fixation with a reduced risk of complications, particularly in older patients with osteoporosis.

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.

Possible Points of Ulnar Nerve Entrapment in the Arm and Forearm: An Ultrasound, Anatomical, and Histological Study

Background: Ulnar nerve entrapment is one of the most common entrapment neuropathies, usually occurring in the cubital tunnel of the elbow and in Guyon’s canal of the wrist. However, it can also occur at other anatomical locations. Purpose: Our aim was to review other possible locations of ulnar nerve entrapment in an ultrasound and anatomical study. Material and Methods: Eleven upper limbs from eight adult corpses were ultrasonographically examined and subsequently dissected in a dissection laboratory. Four specific anatomical points were analysed, and any anatomical variations were documented. Moreover, six samples of the nerve were taken for histological analysis. Results: Distinct anatomical relationships were observed during ultrasound and dissection between the ulnar nerve and the medial intermuscular septum, the triceps aponeurosis, Osborne’s fascia at the elbow, the arcuate ligament of Osborne and the intermuscular aponeurosis between the flexor carpi ulnaris and the flexor digitorum superficialis muscles. A statistical study showed that these locations are potential areas for ulnar nerve compression. In addition, a fourth head of the triceps brachii muscle was found in some specimens. Conclusion: Results demonstrate that ultrasound is a good tool to investigate ulnar nerve entrapment neuropathy and to identify other anatomical points where the nerve can remain compressed.

Ultrasound in the Differential Diagnosis of Medial Epicondylalgia and Medial Elbow Pain-Imaging Findings and Narrative Literature Review

Medial epicondylalgia (ME), commonly known as “the golfer’s elbow”, typically develops in individuals who perform repetitive forearm movements and weight-bearing activities. It accounts for up to 20% of all epicondylitis cases and is most prevalent in particular sports and occupations. Though the diagnosis can be made based on sole clinical examination, additional imaging might be essential for confirmation of medial epicondylitis and excluding other pathologies of the medial epicondyle region. US imaging, with a sensitivity and specificity of 95% and 92%, respectively, remains a practical and accessible alternative to MRI. However, its diagnostic efficacy highly depends on the operator’s experience and requires proper technique. This article describes the ultrasound examination and technique for adequate visualization of elbow joint structures. It also discusses the differential diagnosis of other common and less-known pathologies of the medial compartment of the elbow, including snapping triceps, medial collateral ligament injury, and cubital tunnel neuropathy.

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.

[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.

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.

Clinical Outcomes of Low-Cost, Anchorless Repair of the Triceps Tendon Using a Proximal Knot Technique

Purpose

To use validated outcome measures to evaluate the clinical results of surgical repair of distal triceps tendon ruptures using transosseous tunnels and high-strength sutures with proximally based knots.

Methods

A consecutive series of traumatic distal triceps tendon ruptures at a single institution was studied. All cases were surgically repaired by 1 surgeon using high-strength suture with a bone tunnel-based repair technique. Repair knots were oriented proximally instead of in the traditional distal position. All patients were evaluated at long-term follow-up with a physical examination performed by the orthopaedic surgeon and the following validated outcome measures: Disabilities of the Arm, Shoulder and Hand score; Mayo Elbow Performance Score; and visual analog scale score.

Results

Seven male patients with a mean age of 38 years (range, 19-50 years) and mean follow-up period of 4.1 ± 1.2 years underwent distal triceps tendon repair with bone tunnels and high-strength sutures with proximally positioned knots. Of the repairs, 4 involved the dominant arm. At final follow-up, the mean Disabilities of the Arm, Shoulder and Hand score was 1.3 ± 3.1; the mean Mayo Elbow Performance Score was 99.3 ± 1.9; and the mean visual analog scale score was 0. One additional patient who declined participation in the study had wound dehiscence and infection with an associated partial rerupture.

Conclusions

This case series of triceps tendon repairs using transosseous tunnels and proximally based knots showed favorable postoperative elbow function based on validated outcome measures.

Level of Evidence

Level IV, therapeutic case series.

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.

Is there something new regarding triceps brachii muscle insertion?

PURPOSE

Previous studies have questioned whether the triceps brachii muscle tendon (TBMT) has a double or single insertion on the ulna. Aiming to provide an answer, we describe the anatomy of the TBMT and review a magnetic resonance imaging (MRI) series of the elbow.

METHODS

Forty-one elbows were dissected to assess the details of the triceps brachii insertion. Elbow plastination slices were analyzed to determine whether there was a space on the TBMT. Magnetic resonance imaging from the records of the authors were also obtained to demonstrate the appearance of the pre-tricipital space on MRI.

RESULTS

A virtual space on the medial aspect near the TBTM insertion site in the olecranon was consistently found on anatomic dissections. It was a distal pre-tricipital space. Magnetic resonance imaging demonstrated the appearance of the pre-tricipital space on MRI, and its extension was measured longitudinally either in elbow flexion or extension. There was no statistically significant difference between the measurements of this space in the right and left elbows or between flexion and extension (p > 0.05). The coefficient of variation was <10% for all measurements.

CONCLUSION

Knowledge of this structure may be essential to avoid incorrect diagnosis and unnecessary therapeutic interventions.

Redirection Using Double Pulley Technique for Snapping Triceps Tendon: A Case Report and Technique Note

Background

Snapping triceps tendon is an increasingly recognized clinical entity, which is associated with a variety of pathologic factors. The causative factors include inherited structural or developmental variations, post‐traumatic malalignment, and other reasons. The main complaint of patients with snapping lateral triceps are the snapping sensation, mild muscle weakness of elbow extension, with or without tenderness in distal triceps tendon. Many treatment options have been reported previously, including tendon resection and redirection.

Case presentation

We present the case of a 19‐year‐old boy with post‐traumatic distal lateral head of triceps tendon dislocation who complained of extension weakness and snapping sensation in his left elbow. Then, we used two‐strand‐overhand locking (TSOL) knot combined with double pulley technique to redirect the snapping triceps tendon.

Conclusion

The patient recovered well after the operation without complaining of discomfort. This fixing and redirection tendon technique, described previously for repairing rotator cuff tears, may be applied in a similar fashion for the snapping triceps tendon with promising clinical results.

Traumatic medial luxation of the triceps brachii tendon with medial subluxation of the elbow joint in a dog

OBJECTIVE

To describe the surgical reduction of luxation of the triceps brachii tendon in a dog.

ANIMAL

One 2.5-year-old 2.58 kg castrated male toy poodle.

STUDY DESIGN

Clinical case report.

METHODS

The dog displayed intermittent, non-weight bearing lameness of the right forelimb for approximately 18 months before presenting at the veterinary medical center. Medial subluxation of the right elbow joint was detected by palpation. The Campbell test was consistent with an increased range of motion during supination. At ultrasonographic examination, medial luxation of the triceps brachii tendon was noted, whereas collateral ligaments appeared normal. No skeletal deformities were found on radiographs of the right forelimb. The luxation of the triceps brachii tendon was surgically corrected with antirotational suture, a stopper pin, medial retinaculum release, and imbrication of the lateral retinaculum.

RESULTS

The right triceps brachii tendon and elbow joint were successfully reduced. Gait returned to normal by 55 days postoperatively. No implant failure or recurrence were observed 3.5 years after surgery.

CONCLUSION

Surgical reduction of a luxation of the triceps brachii tendon in a dog resolved lameness and restored the range of motion of the affected elbow, leading to good long-term outcome.

Ultrasonography of the ulnar nerve in the elbow: video article

Disorders affecting the ulnar nerve in the elbow are common in clinical practice. The diagnosis is based on clinical evaluation and electrodiagnostic tests, but imaging examinations are frequently necessary, particularly for the identification of the structures associated with nerve compression. The purpose of this video article is to review the anatomy, the pathology, scanning techniques, and sonographic appearance of the ulnar nerve in the elbow.

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.
