Ultrasound diagnosis of triceps tendon rupture. A report of 2 cases

Case report: Nonsimultaneous bilateral triceps tendon rupture and surgical repair in a healthy dog

A 7-year-old female spayed Australian shepherd dog was presented for an acute onset of inability to stand. On physical examination, the dog was unable to support weight on the thoracic limbs. On neurological examination, the thoracic limbs had absent hopping and paw placement and reduced withdrawal reflexes bilaterally. The remainder of the neurological examination was normal. The anatomic lesion localized to the C6-T2 spinal nerve roots, spinal nerves, or the named nerves of the thoracic limb, bilaterally. A lesion affecting the ventral gray column of the C6 through T2 spinal cord segments was considered less likely. In an effort to exclude an orthopedic disorder from consideration, radiographs of the shoulders, elbows, and manus were normal. Magnetic resonance imaging of the cervical and cranial thoracic vertebral column was normal. Analysis of synovial fluid from the carpi, elbows, and shoulders were normal. Ultrasonography of the triceps muscle and tendon of insertion revealed bilateral, acute-subacute tears of the tendon at insertion of the triceps muscles, bilaterally. Magnetic resonance imaging of both elbows revealed complete avulsion of the triceps tendons bilaterally. Surgical repair of both tendons was performed using the Arthrex FiberLoop system combined with autologous conditioned plasma soaked in a collagen sponge. Postoperatively, external coaptation was provided using Spica splints for 6 weeks followed by the use of soft padded orthotic braces for an additional 6 weeks. Concurrently, a front support wheelchair was used for 10 weeks postoperative. By 10 weeks postoperative, the dog was able to ambulate without support. To the authors' knowledge, this is the first report of bilateral triceps tendon avulsion in a dog. Tendon avulsion occurred without a known history of trauma or predisposing metabolic abnormalities. Magnetic resonance imaging provided excellent anatomical detail that aided in surgical repair.

Bone suture anchor repair and functional outcome of a triceps tendon rupture, a rare clinical entity

Triceps tendon rupture is rare and easily missed on presentation. A 58-year-old man was seen in our accident and emergency department with an inability to extend his right elbow against gravity after he fell. Ultrasound and MRI confirmed the suspected diagnosis of a traumatic triceps tendon rupture and excluded additional injuries. Surgical repair was carried out by a bone anchor suture reinsertion of the tendon to the olecranon. After 2 weeks of cast immobilisation, an early active range of motion (ROM) rehabilitation schedule was followed, resulting in excellent elbow function at 12 weeks postoperatively.In conclusion, it is important to suspect this rare injury and use additional studies to confirm the diagnosis of triceps tendon rupture. Also, good clinical outcome with regards to function can be achieved using bone anchor suture repair and an early active ROM rehabilitation schedule.

Ultrasonographic Technique, Appearance, and Diagnostic Accuracy for Common Elbow Sports Injuries

Ultrasonography is a valuable diagnostic imaging tool because of its availability, tolerability, low cost, and utility in real-time dynamic evaluation. Its use in diagnosing elbow injuries has expanded recently and continues to do so. In particular, stress ultrasonography represents a unique imaging technique that directly visualizes the ulnar collateral ligament (UCL) and allows the assessment of ligament laxity, offering an advantage over magnetic resonance imaging and magnetic resonance arthrography in this patient population. Furthermore, ultrasonography has shown particular usefulness in instances where invasive techniques might be less desirable. This is particularly important in athletes since more invasive procedures potentially result in lost time from their sport. Ultrasonography is an important imaging tool that complements a thorough history and physical examination in the evaluation of elbow injuries in athletes. The use of ultrasonography in orthopaedic sports medicine has been investigated previously; however, to our knowledge, there has been no comprehensive review regarding the utility of ultrasonography for common elbow injuries in athletes. The current study provides a comprehensive, detailed review of the utility and indications for the use of ultrasonography for common elbow injuries in athletes.

Distal Triceps Tendon Injuries

Distal triceps ruptures are uncommon, usually caused by a fall on an outstretched hand or a direct blow. Factors linked to injury include eccentric loading of a contracting triceps, anabolic steroid use, weightlifting, and traumatic laceration. Risk factors include local steroid injection, hyperparathyroidism, and olecranon bursitis. Initial diagnosis can be complicated by pain and swelling, and a palpable defect is not always present. Plain radiographs can be helpful. MRI confirms the diagnosis and directs treatment. Incomplete tears can be treated nonsurgically; complete tears are best managed surgically. Good to excellent restoration of function has been shown with surgical repair.

Distal insertional anatomy of the triceps brachii muscle: MRI assessment in cadaveric specimens employing histologic correlation and Play-doh® models of the anatomic findings

OBJECTIVES

Assess the insertional anatomy of the distal aspect of the triceps brachii muscle using magnetic resonance imaging (MRI) in cadavers with histologic correlation and Play-doh^® models of the anatomic findings.

MATERIALS

Elbows were obtained from twelve cadaveric arm specimens by transverse sectioning through the proximal portion of the humerus and the midportion of the radius and ulna. MRI was performed in all elbows. Two of the elbow specimens were then dissected while ten were studied histologically. Subsequently, Play-doh^® models of the anatomic findings of the distal attachment sites of the triceps brachii muscle were prepared.

RESULTS

MRI showed a dual partitioned appearance of the distal attachment sites into the olecranon in all specimens. In the deeper tissue planes, the medial head muscle insertion was clearly identified while superficially, the terminal portion of the long and lateral heads appeared as a conjoined tendon. Histologic analysis, however, showed continuous tissue rather than separate structures attaching to the olecranon.

CONCLUSION

Although MRI appeared to reveal separate and distinct attachments of the triceps brachii muscle into the olecranon, histologic analysis delineated complex but continuous tissue related to the attachments of the three heads of this muscle. The Play-doh^® models were helpful for the comprehension of this complex anatomy and might serve as a valuable educational tool when applied to the analysis of other musculoskeletal regions.

Operative Management of Acute Triceps Tendon Ruptures: Review of 184 Cases

BACKGROUND

Distal triceps tendon ruptures are rare. The authors present a series of 184 surgically treated, acute, traumatic triceps tendon avulsions and compare the complications between those treated with anchors (A) versus transosseous (TO) suture repair.

HYPOTHESIS

No difference exists in the retear rate between TO and A repairs. Study Designed: Cohort study; Level of evidence, 3.

METHODS

All patients who underwent an open primary repair of a traumatic triceps tendon avulsion within 90 days of injury, between 2007 and 2015, were retrospectively reviewed. Surgeries were performed within a multisurgeon (75 surgeons), multicenter (14 centers), community-based integrated health care system. Patient demographic information, type of repair, complications, and time from surgery to release from medical care were recorded.

RESULTS

184 triceps tears in 181 patients met the inclusion criteria. The mean age was 49 years (range, 15-83 years). There were 169 males. The most common mechanisms of injury were fall (56.5%) and weight lifting (19%). Mean time from injury to surgery was 19 days (range, 1-90 days); in 74.5% of cases, surgery was performed in 3 weeks or less. There were 105 TO and 73 A repairs. No significant difference was found between the two groups in the mean age ( P = .18), sex ( P = .51), completeness of tears ( P = .74), tourniquet time ( P = .455), and prevalence of smokers ( P = .64). Significant differences were noted between TO and A repairs in terms of reruptures (6.7% vs 0%, respectively; P = .0244), overall reoperation rate (9.5% vs 1.4%; P = .026), and release from medical care (4.3 vs 3.4 months; P = .0014), but no difference was seen in infection rate (3.8% vs 0%; P = .092). No difference was noted in release from medical care in patients who underwent surgery 3 weeks or less after injury compared with those undergoing surgery more than 3 weeks after injury (3.90 vs 4.09 months, respectively; P = .911).

CONCLUSION

Primary repair of triceps ruptures with TO fixation has a significantly higher rerupture rate, higher reoperation rate, and longer release from medical care than does repair with A fixation. Implementation of suture anchors in triceps repairs offers a lower complication rate and earlier release from medical care.

Biceps and Triceps Ruptures in Athletes

Although rare, biceps and triceps tendon ruptures constitute significant injuries that can lead to profound disability if left untreated, especially in the athletic population. Biceps rupture is more common than triceps rupture, with both resulting from a forceful eccentric load. Surgical repair is the treatment method of choice for tendinous ruptures in athletes. Nonoperative management is rarely indicated in this population and is typically reserved for individuals with partial ruptures that quickly regain strength and function. Surgical anatomy, evaluation, diagnosis, and surgical management of these injuries are covered in this article.

Osteochondroma of the Rib: a rare radiological apeareance

Introduction:

Osteochondromas (exostosis) are the most common neoplasm of bone and arise from the metaphysis of bones. Tumors of the chest wall comprise approximately 2% of all tumors of the body and may be primary or metastatic, benign or malignant. Osteochondroma is a common bone tumor but a rare tumor in the rib. It is often asymptomatic and observed incidentally. The tumors typically begin to grow before puberty and continue until bone maturation is reached. Surgery is required in childhood if these lesions are painful or disfiguring, while those arising in adulthood should always be resected.

Case Report:

9 yr old boy presented to OPD with swelling over right chest. Radiograph showed bony outgrowth on the lateral aspect of the 6th rib. The patient was kept under closed observation and was treated conservatively. Three years follow-up didn’t show any increase in the size of the swelling and the patient did not have any complaints.

Conclusion:

Though various studies have shown that the surgical resection of osteochondroma is necessary to avoid further complications of Haemothorax, pneumothorax or intercostal neuralgia, we concluded that osteochondroma of the ribs can even be conserved if not associated with complications and patient does not need to undergo unnecessary surgery.

Chronic Tendonopathy as a Unique Cause of Non Traumatic Triceps Tendon Rupture in a (Risk Factors Free) Bodybuilder: A Case Report

Introduction:

Distal triceps tendon rupture is an uncommon lesion rarely due to a non-traumatic mechanism. In these cases, the majority of patients show predisposing factors for tendon degeneration: underlying medical co-morbidities, previous systemic and locally injected corticosteroids and systemic anabolic steroids. A clear evidence for an etiopathogeneticroleforchronictendonopathy in triceps tendon rupture is sti 11 lacking.

Case Report:

We report the case of a rare non-traumatic complete rupture of the triceps tendon, at the olecranon insertion, occurring in a healthy male middle-aged non-professional bodybuilder. He presented to our attention with a five days history of weakness, swelling and pain at the left elbow, started after a snapping sound during a single arm triceps extension exercise. He was a healthy sportsman, no smoker and no drinker. He had suffered, in the two months before, of mild bilateral exercise-related elbow discomfort, never limiting his sport and daily activities. The man was treated by an early surgical repair. Histological analysis was conducted on intraoperative samples. The treatment allowed complete remission and return to sport practice without functional deficit.

Conclusion:

An overload-related chronic tendonopathy was identified as the unique factor with causal role in the determinism of the above described lesion. This case highlights, for the first time in literature, that just a chronic tendonopathy, in absence of any other predisposing condition, can lead to a non-traumatic complete triceps tendon rupture.

Distal Triceps Tendon Injuries

Acute triceps ruptures are an uncommon entity, occurring mainly in athletes, weight lifters (especially those taking anabolic steroids), and following elbow trauma. Accurate diagnosis is made clinically, although MRI may aid in confirmation and surgical planning. Acute ruptures are classified on an anatomic basis based on tear location and the degree of tendon involvement. Most complete tears are treated surgically in medically fit patients. Partial-thickness tears are managed according to the tear severity, functional demands, and response to conservative treatment. We favor an anatomic footprint repair of the triceps to provide optimal tendon to bone healing and, ultimately, functional outcome.

Triceps tendon rupture: the knowledge acquired from the anatomy to the surgical repair

Triceps injuries are relatively uncommon in most traumatic events, and the distal triceps tendon ruptures are rare. Recently, the knowledge of this tendon lesion has increased, and it seems to be related to more precise diagnostic and clinical assessments. The most common mechanism of injury remains a forceful eccentric contraction of the muscle, while several other risk factors have been studied as chronic renal failure, endocrine disorders, metabolic bone diseases as well as steroid use. Olecranon bursitis and local corticosteroid injections may also play a role. The commonest site of rupture is at the tendon's insertion into the olecranon and rarely at the myotendinous junction or intramuscularly. The surgical intervention is recommended in acute complete ruptures, and non-operative treatment is reserved for patients with major comorbidities, as well as for partial ruptures with little functional disability and in low demanding patients. Various techniques and approaches as the direct repair to bone, the tendon augmentation, the anconeus rotation flap and the Achilles tendon allograft have been proposed for the management of these challenging injuries. The goal of surgical management should be an anatomical repair of the injured tendon by selection of a procedure with a low complication rate and one that allows early mobilization. This manuscript focuses the triceps tendon ruptures starting from the anatomy to the diagnosis and entity of the triceps tendon injuries, as well as the indications and guidelines for the management.

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.

Triceps tendon reconstruction using ipsilateral palmaris longus autograft in unrecognized chronic tears

Injury to the distal triceps tendon is uncommon and can be difficult to diagnose, especially when a partial rupture or tear occurs. In situations where an incomplete disruption to the musculotendinous unit occurs, a palpable defect or clear functional loss may not be present. Advanced imaging techniques, such as magnetic resonance imaging or ultrasound, can be used to confirm the diagnosis and define the extent of injury. The treatment of a complete rupture of the distal triceps tendon is repair or reconstruction, whereas the management of a patient with a partial triceps rupture is related to the pain, functional deficit, and expectations of the patient. This article presents 2 patients with chronic, near complete disruptions of the distal triceps tendon. In both patients, surgical reconstruction of the injured tendon was accomplished using ipsilateral palmaris longus autograft. This technique allows the treating surgeon to harvest the graft from the ipsilateral upper extremity. The palmaris autograft is then used to reconstruct the injured portion of the triceps tendon using a Pulvertaft weave technique through the intact triceps tendon and osseous tunnels within the proximal ulna. This technique allows for easy surgical setup and harvest of autograft tendon and provides a structurally sound technique for a tension-free reconstruction of the injured tendon. It also permits early postoperative elbow range of motion, with active elbow extension allowed at 6 weeks. The authors have used this technique successfully in the treatment of chronic partial tears of the distal triceps tendon.

Distal partial ruptures of triceps brachii tendon in an athlete

Distal brachii triceps tendon rupture is rare. Partial lesions are not so well defined. If functionally they are well tolerated in patients with low functional demand, management guideline is not so clear for sportsmen. To our best knowledge, there is no reported technique for the repair of partial forms. A 28-year-old patient was operated on for a partial triceps rupture. He underwent a transosseous olecranon suture of the tricipital tendon, with a side-to-side suture to the healthy residual tendon. The patient was assessed at 2 years follow-up with the DASH score. He had painless and mobile elbow with no effusion and returned to sport 4 months after his surgical repair. The extension strength was comparable to the healthy side (5/5). The DASH score was 1,7 for global score, and 6,3 for work and sport modules. Partial rupture of brachii triceps tendon is not well tolerated in high functional demand patients. We think that patients should be operated in these situations and may achieve excellent results. Postoperative management is crucial to achieve good results as well as in complete rupture.

Sonography of partial-thickness tears of the distal triceps brachii tendon

OBJECTIVES

The purpose of this study was to retrospectively characterize the sonographic appearance of partial-thickness distal triceps brachii tendon tears.

METHODS

After Institutional Review Board approval, sonographic records were searched for patients who had an unequivocal partial-thickness triceps tendon tear at surgery or magnetic resonance imaging. Sonograms were retrospectively characterized for tendon discontinuity of the superficial or deep layers, tendon retraction, osseous fracture fragments, and joint effusion. Imaging findings were then compared with clinical, imaging, and surgical results.

RESULTS

Five patients had a partial-thickness distal triceps brachii tendon tear at surgery (n = 4) or magnetic resonance imaging (n = 1). All cases only involved the superficial tendon layer (combined long and lateral heads) with retraction of a fractured olecranon enthesophyte fragment. The deep tendon layer (medial head) was intact in all cases with no joint effusion.

CONCLUSIONS

Partial-thickness distal triceps brachii tendon tears have a characteristic appearance with selective superficial tendon retraction and olecranon enthesophyte avulsion fracture.

Distal triceps rupture

Distal triceps rupture is an uncommon injury. It is most often associated with anabolic steroid use, weight lifting, and laceration. Other local and systemic risk factors include local steroid injection, olecranon bursitis, and hyperparathyroidism. Distal triceps rupture is usually caused by a fall on an outstretched hand or a direct blow. Eccentric loading of a contracting triceps has been implicated, particularly in professional athletes. Initial diagnosis may be difficult because a palpable defect is not always present. Pain and swelling may limit the ability to evaluate strength and elbow range of motion. Although plain radiographs are helpful in ruling out other elbow pathology, MRI is used to confirm the diagnosis, classify the injury, and guide management. Incomplete tears with active elbow extension against resistance are managed nonsurgically. Surgical repair is indicated in active persons with complete tears and for incomplete tears with concomitant loss of strength. Good to excellent results have been reported with surgical repair, and very good results have been achieved even for chronic tears.

The role of ultrasound in the evaluation of sports medicine injuries of the upper extremity

The two major imaging modalities used for assessment of soft tissue injuries are ultrasound and MRI. Although ultrasound of the extremities is used only to a limited extent in the United States, it is widely used in many other countries for evaluation of extremity injuries. This article first considers the advantages and disadvantages of MRI and ultrasound. Understanding these differences will help the reader understand the role of ultrasound as compared with MRI in evaluating upper extremity injuries. The uses of ultrasound for evaluating sports medicine injuries in specific regions of the upper extremity are then reviewed. Where the data are available, the reported accuracy of ultrasound is compared with MRI for each type of injury.

Ultrasound of the shoulder and elbow

Ultrasound examination of the shoulder and elbow requires careful technique, appreciation of normal anatomy, and appropriate high-end equipment. Ultrasound provides detailed diagnostic information. Its accuracy is comparable to that of MRI in the assessment of the rotator cuff. Ultrasound is cheaper than MRI and is preferred by patients.

Demonstration of the appearance of the paraspinal musculoligamentous structures of the cervical spine using ultrasound

The application of ultrasound in the imaging of the neck has primarily focussed on anterior structures (e.g., thyroid gland). Structures located on the posterior aspect of the neck have received little attention. This study illustrates the capability of modern ultrasound equipment in visualising the musculoligamentous structures of the neck, particularly the paraspinal musculature. Ten healthy adult volunteers (6 female; 4 male) underwent ultrasound examination of the cervical spine. A standardised technique for transducer placement was adopted and successive images of the neck of each subject were obtained. Spatial compound (extended field of view) images were obtained in subjects using one of two different ultrasound systems. Images of structures produced by ultrasound were compared to those achieved with magnetic resonance imaging in three subjects. Identification of key landmarks aided orientation and identification of structures. The internal architecture of the musculoligamentous structures of the cervical spine, especially the posterior neck muscles, was demonstrated well using ultrasound. Our study showed that modern ultrasound equipment is capable of producing clear images of the posterior cervical spine musculature and certain bony features.

Biceps tendon and triceps tendon injuries

Injuries to the biceps and triceps tendons about the elbow are relatively infrequent. Typically, they are traumatic events that occur as a result of a forceful eccentric contraction. Early recognition of these injuries and prompt intervention are the cornerstones to a successful outcome. Acute anatomic repair of complete injuries offers predictably good results. Conservative management, on the other hand, is typically reserved for partial injuries with little functional compromise, and for patients unfit for surgery. The challenges posed by chronic injuries can be addressed with a variety of surgical options. This article focuses on the timely identification and diagnosis of these injuries and specific indications and guidelines for their treatment.

Ultrasound of the elbow

The elbow is an important synovial hinge joint of the upper extremity. This joint represents a common site of musculoskeletal symptomatology, affecting all age groups. The advantages of ultrasound imaging of the elbow include easy availability, multiplanar capability and the ability to assess structures dynamically. Patient symptomatology and site of maximal tenderness can be directly correlated with imaging findings. Comparison is easily made with the contralateral side. Particular strengths include the ability to assess para-articular structures, such as regional tendons and ligaments, in addition to assessment of joint effusions, loose bodies and regional bursae. With operator experience and excellent technique, ultrasound is a valuable imaging tool for assessment of disorders of the elbow joint.

Surgical treatment of distal triceps ruptures

BACKGROUND

Distal triceps tendon ruptures occur rarely, and the diagnosis is often missed when the injury is acute. The literature provides little guidance regarding treatment or the outcome of treatment of these injuries. The goal of this report was to present our experience with the diagnosis, timing and technique of surgical treatment, and outcome of treatment of distal triceps tendon ruptures in twenty-two patients. None of the ruptures followed joint replacement.

METHODS

Twenty-three procedures were performed in twenty-two patients with an average age of forty-seven years. The average duration of follow-up was ninety-three months (range, seven to 264 months). Data were obtained by a retrospective review of records and radiographs before and after surgery. Also, thirteen patients returned for follow-up and were examined clinically. Six additional patients responded to a telephone questionnaire. One patient was lost to follow-up, and two had died. Formal biomechanical evaluation of isokinetic strength and isokinetic work was performed in eight patients, at an average of eighty-eight months after surgery. Isokinetic strength data were available from the charts of two additional patients.

RESULTS

Ten of the triceps tendon ruptures were initially misdiagnosed. At the time of diagnosis, triceps weakness with a decreased active range of motion was found in most patients, and a palpable defect in the tendon was noted after sixteen ruptures. Operative findings revealed a complete tendon rupture in eight cases and partial injuries in fifteen. Fourteen primary repairs and nine reconstructions of various types were performed. Three of the primary repairs were followed by rerupture. At the time of follow-up, the range of elbow motion averaged 10 degrees to 136 degrees. All but two elbows had a functional range of motion; however, the lack of a functional range in the two elbows was probably due to posttraumatic arthritis and not to the triceps tendon rupture. Triceps strength was noted to be 4/5 or 5/5 on manual testing in all examined subjects. Isokinetic testing of ten patients showed that peak strength was, on the average, 82% of that of the untreated extremity. Testing showed the average endurance of the involved extremity to be 99% of that of the uninvolved arm. The results after repair and reconstruction were comparable, but the patients' recovery was slower after reconstruction.

CONCLUSIONS

The diagnosis of distal triceps tendon rupture is often missed when the injury is acute because of swelling and pain. Primary repair of the ruptured tendon is always possible when it is performed within three weeks after the injury. When the diagnosis is in doubt immediately after an injury, the patient should be followed closely and should be reexamined after the swelling and pain have diminished so that treatment can be instituted before the end of this three-week period. Reconstruction of the tendon is a much more complex, challenging procedure, and the postoperative recovery is slower. Thus, we believe that early surgical repair, within three weeks after the injury, is the treatment of choice for distal triceps tendon ruptures. of evidence.

Imaging of the elbow in the overhead throwing athlete

Elbow injuries in athletes who perform overhead throwing motions often present diagnostic challenges because of the undue stresses and often chronic, repetitive patterns of injury. Accurate and efficient assessment of the injured elbow is essential to maximize functional recovery and expedite return to play. Radiographic evaluation should be tailored to the specific injury suspected and requires a thorough understanding of normal anatomic relationships as well as familiarity with common injuries affecting these athletes.

Traumatic avulsion of the triceps brachii

Traumatic avulsion of the triceps brachii tendon is a rare injury. Clinical diagnosis shows that elbow extension against gravity is not possible. Radiologically, the lateral elbow may show the presence of flecks of avulsed osseous material from the olecranon ("flake sign"), which is almost pathognomonic of this lesion. The authors of the present study present a case of avulsion fracture treated with the attachment of bone suture anchors.

Ultrasound of the elbow

This article describes the use of ultrasound (US) in the evaluation of the elbow. US is able to visualize several abnormalities affecting tendons, muscles, ligaments and bursae around the elbow joint as well as to delineate the nature of soft-tissue swelling, such as a space-occupying lesion or synovial enlargement. Occult fractures, osteophytes and intra-articular loose bodies can be depicted with this technique as well. At the cubital tunnel, US allows accurate imaging of the ulnar nerve and to document changes that occur in compressive syndromes. Over other imaging modalities, US offers several key advantages, including cost effectiveness, availability and ability to perform a dynamic examination of tendon movement and joint motion. With continued experience, it is likely that the use of US will increase further with regards to evaluation of soft-tissue abnormalities of the elbow.

Imaging of elbow disorders

Numerous modalities are available for imaging the elbow. Radiographs should be the first imaging procedure performed for evaluation of an elbow abnormality. The use of advanced imaging modalities such as MR imaging, CT, and sonography also is discussed in this article.

Biceps and triceps injuries of the elbow

In this article, the common biceps and triceps injuries about the elbow are reviewed. The relevant anatomy, presenting signs, symptoms, and treatment of these injuries are discussed.
