Misdiagnosed avulsion fracture of the triceps tendon from the olecranon insertion: case report

[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 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.

A Narrative Review on Avulsion Fractures of the Upper and Lower Limbs

Avulsion fractures compromise function and movement at the affected joint. If left untreated, it can lead to deformity, nonunion, malunion, pain, and disability. The purpose of this review was to identify and describe the epidemiology and available treatment options for common avulsion fractures of the upper and lower extremities. Current evidence suggests that optimal treatment is dependent on the severity of the fracture. Conservative efforts generally include casting or splinting with a period of immobilization. Surgery is typically indicated for more severe cases or if nonoperative treatments fail; patient demographics or preferences and surgeon experience may also play a role in decision making. Some avulsion fractures can be surgically managed with any one of various techniques, each with their own pros and cons, and often there is no clear consensus on choosing one technique over another; however, there is some research suggesting that screw fixation, when possible, may offer the best stability and compression at the fracture site and earlier mobilization and return to function. Physicians should be mindful of the potential complications associated with each intervention.

A treatment algorithm for the management of distal triceps ruptures

Rupture of the distal triceps brachii muscle is a relatively rare, but potentially troublesome injury. Recent literature has increased awareness of the injury and highlighted the importance of accurate diagnosis and prompt appropriate treatment of these injuries. The history, physical examination findings, and imaging studies are key to determine complete versus partial rupture of the distal triceps. We propose a treatment algorithm based on the chronicity of the injury and associated tendon quality. Such a guide can help surgeons navigate the most appropriate treatment and be equipped with the surgical tools to provide the best surgical result.

Treatment of a Complex Distal Triceps Tendon Rupture With a New Technique: A Case Report

Introduction:

The distal triceps tendon rupture is an uncommon injury. The acute treatment is well-defined, but when a delayed diagnosis is made or when a tendon retraction is present the alternatives or reconstruction are limited and sometimes complex.

Case Presentation:

In this case, we report on a 28-year-old man who presented with a chronic disruption of the distal triceps tendon with a gap of approximately 15 cm. The patient was diagnosed in another center with an inveterate breakage of the distal triceps tendon and was initially treated with an Achilles allograft that was complicated by a wound infection and required more than ten surgeries. Nearly 22 months after the initial trauma, and 12 months after the first surgery, we performed a reconstruction with an Achilles tendon allograft using the new technique of distal attachment. At the 12-month follow-up the patient presented a joint balance from -5º to 110º and presented with no pain.

Conclusions:

The use of an Achilles tendon allograft provides excellent results in complex distal triceps tendon ruptures. We report the use of a new technique to anchor a distal Achilles allograft.

Diagnosis and treatment of triceps tendon injuries: a review of the literature

OBJECTIVE

To elucidate mechanism of injury, nonoperative protocols, surgical techniques, rehabilitation schedules, and return to sports guidelines for partial and complete triceps tendon injuries.

DATA SOURCES

The PubMed and OVID databases were searched in 2010 and peer-reviewed English language articles in 2011.

MAIN RESULTS

After a fall on an outstretched hand, direct trauma on the elbow, or lifting against resistance, patients often present with pain and weakness of extension. Examination may reveal a palpable tendon gap, and radiographs may reveal a Flake sign. Acute partial injuries have positive outcomes with immobilization in 30-degree flexion for 4 to 6 weeks. Primary repair for complete rupture can restore normal extensor function after 3 to 4 months. Reconstruction returns normal extensor function up to 4 years. Most authors support postoperative immobilization for 2 to 3 weeks at 30- to 40-degree flexion, flexion block bracing for an additional 3 weeks, and unrestricted activity at 6 months. Athletes may be able to return to sports after 4 to 5 weeks of recovery from a partial injury, but return may be delayed if operative tendon repair is performed.

CONCLUSIONS

Acute partial triceps tendon injuries may be managed conservatively at first and should be repaired primarily if this fails or if presentation is delayed. Reconstruction should first use the anconeus rotation technique. If the anconeus is devitalized, the Achilles tendon may be the allograft of choice.
