Sonography of Cubital Bursitis

Clinical efficacy of ultrasound-guided injection in the treatment of olecranon subcutaneous bursitis

BACKGROUND

Recent studies have shown that ultrasound-guided injection of glucocorticoids is superior to blind puncture methods.

OBJECTIVE

To evaluate clinical efficacy of ultrasound-guided drug injection in the treatment of olecranon subcutaneous bursitis.

METHODS

From June 2016 to September 2018, 45 patients diagnosed with obvious synovial effusion and treated with ultrasound-guided injection therapy for olecranon bursitis were included in this study. Under the guidance of ultrasound, the synovial effusion aspiration was performed and 2 ml of the compound betamethasone mixture was injected into the bursae and dressed under pressure. Ultrasound examination was performed 2 weeks after operation and the secondary fluid aspiration and drug injection treatment were performed. The depth of synovial effusion, the thickness of synovial hyperplasia and the blood flow signal were measured 4 weeks after operation to evaluate the therapeutic effect.

RESULTS

After first treatment, the recurrence rate of the olecranon mass were 40%. After secondary treatment, recurrence of olecranon mass occurred in 6 of the 45 patients with a recurrence rate of 13.3%. After 4 weeks of follow-up, the depth of olecranon synovial effusion, the average thickness of synovial hyperplasia and the blood flow signal decreased significantly after treatment (P < 0.05).

CONCLUSIONS

Ultrasound-guided drug injection is safe and effective in treating olecranon subcutaneous bursitis. Although the recurrence rate is high after the first treatment, the second treatment is simple and can reduce the recurrence rate. The patients have a high acceptance rate, which is worthy of clinical promotion.

Imaging bicipitoradial bursitis: a pictorial essay

Although bicipitoradial bursitis is not commonly seen, when it does occur, it can frequently lead to diagnostic difficulty, mimicking either a soft-tissue tumor or infection. Lack of awareness of this uncommon entity can lead to unnecessary anxiety or tissue biopsy. This pictorial essay discusses the normal anatomy of the bicipitoradial bursa and the spectrum of imaging findings of bicipital bursitis.

Ultrasound evaluation of bursae: anatomy and pathological appearances

A bursa is an extra-articular sac that may communicate with a joint and functions to decrease friction between tendons and either bone or skin. Bursae can be classified as native and non-native (adventitious) bursae. The native bursae are lined with a synovial membrane and occur at predictable anatomical sites; knowledge of these normal structures can help distinguish them from other pathological entities. An adventitious bursa can form at sites of friction rather than at predictable anatomical sites, but otherwise have imaging features similar to native bursae. Bursal distention can occur from many pathological processes, most commonly resulting from chronic overuse injury. When imaging bursal pathological conditions, there is often an overlap of imaging findings, regardless of the cause. In general, ultrasound of a distended bursa reveals a fluid collection with either simple anechoic or more complex hypoechoic fluid. Bursal distention is characteristically unilocular and compressible, unlike other structures such as ganglion cysts, which are usually multilocular and non-compressible. This article reviews the anatomical locations of common bursae and shows pathological examples using ultrasound. Knowledge of typical locations and imaging appearances of bursae can aid in narrowing the differential diagnosis and guiding further management and treatment decisions.

Endoscopic Resection of the Bicipitoradial Bursa

The bicipitoradial bursa lies at the insertion of the biceps tendon on the radial tuberosity. It is an unusual site for chronic bursitis. It can be treated conservatively with aspiration and steroid injection. Surgical excision of the bursa is indicated in case of infection cause, failed conservative treatment with recurrence of the enlarged bursa and pain after aspiration, the presence of nerve compression with neurological impairment, mechanical limitation to flexion and extension of the elbow or biceps tendon degeneration, and/or functional impairment. Open resection through the anterior approach requires extensive dissection to expose the radial tuberosity and the radial neck, which increases the risk of neurovascular injury. Endoscopic resection is possible through distal biceps tendoscopy and endoscopy around the radial neck. It is technically demanding and should be reserved to the experienced elbow arthroscopist.

Antecubital Fossa Solitary Osteochondroma with Associated Bicipitoradial Bursitis

Antecubital fossa lesions are uncommon conditions that present to the orthopaedic clinic. Furthermore, the radius bone is an uncommonly reported location for an osteochondroma, especially when presenting with a concurrent reactive bicipitoradial bursitis. Osteochondromas are a type of developmental lesion rather than a true neoplasm. They constitute up to 15% of all bone tumours and up to 50% of benign bone tumours. They may occur as solitary or multiple lesions. Multiple lesions are usually associated with a syndrome known as hereditary multiple exostoses (HME). Malignant transformation is known to occur but is rare. Bicipitoradial bursitis is a condition which can occur as primary or secondary (reactive) pathology. In our case, the radius bone osteochondroma caused reactive bicipitoradial bursitis. The differential diagnosis of such antecubital fossa masses is vast but may be narrowed down through a targeted history, stepwise radiological investigations, and histological confirmation. Our aim is to ensure that orthopaedic clinicians keep a wide differential in mind when dealing with antecubital fossa mass lesions.

Image-guided elbow interventions: a literature review of interventional treatment options

Over the years, a wide range of image-guided interventional therapies have been used in treating different elbow pathologies, many of which are predominantly based on anecdotal and low-level study findings. This article critically assesses the existing literature and discusses the efficacy of the most commonly utilized interventional procedures for elbow pathology.

Sonographically guided distal biceps tendon injections: techniques and validation

OBJECTIVES

The primary purpose of this investigation was to describe and validate sonographically guided techniques for distal biceps peritendinous/intratendinous injections using a cadaveric model.

METHODS

A single experienced operator completed 18 sonographically guided distal biceps peritendinous injections and 15 sonographically guided distal biceps intratendinous injections in 18 unembalmed cadaveric elbow specimens (11 male and 7 female; age, 53-100 years; body mass index, 19.4-42.2 kg/m(2)). Four different peritendinous approaches were used to inject 3 mL of diluted yellow latex: (1) anterior/superficial, (2) posterior/superficial, (3) posterior/deep/short-axis (to the distal biceps tendon), and (4) posterior/deep/long-axis (to the distal biceps tendon). Three different intratendinous approaches were used to inject 1 mL of diluted blue latex: (1) anterior, (2) anterior/pronator window, and (3) posterior. The feasibility of all 7 injections was assessed by the operator in all specimens, and execution difficulty was recorded after each injection. Specimens were subsequently dissected to assess injectate placement.

RESULTS

All 18 peritendinous distal biceps tendon injections accurately placed latex around the tendon without injecting into the tendon proper. All posterior/superficial peritendinous injections delivered injectate to the ulnar side of the tendon. All posterior/deep peritendinous injections delivered injectate to the radial side of the tendon, with the long-axis approach being technically easier than the short-axis approach. Anterior/superficial peritendinous injections delivered injectate predominantly to the anterior side of the tendon and resulted in 1 brachial artery injury. All but 1 of 15 distal biceps intratendinous injections (93%) accurately placed injectate into the tendon proper, with 1 of 5 anterior injections delivering injectate primarily deep to the paratenon. The posterior intratendinous approach was technically the easiest. No intratendinous injection resulted in neurovascular injury.

CONCLUSIONS

Sonographically guided distal biceps peritendinous/intratendinous injections are feasible and therefore may play a role in the management of patients presenting with distal biceps tendinopathy/bursopathy.

Preoperative diagnosis of bicipitoradial bursitis: a case report

Inflammation of the bicipitoradial bursa is a rare condition and only few reports can be found in literature. Several causes for a cubital bursitis have been suggested in the past. The need to include a malignant lesion in the differential diagnosis has only been mentioned in one of these reports. May main objective in reporting this case is to make this pathological entity better known.

Bicipitoradial Bursitis: A Review of Clinical Presentation and Treatment

The bicipitoradial bursa lies at the insertion of the biceps tendon on the radial tuberosity. It is an unusual site for chronic bursitis and most often results from repetitive mechanical trauma or overuse. Other causes include tuberculosis, immunological complications of rheumatological disease and synovial chondromatosis. Accurate diagnosis requires imaging studies and sometimes histological study. It can be treated conservatively with aspiration and steroid injection. Surgical excision of the bursa is indicated in the case of infection cause, failed conservative treatment with recurrence of the enlarged bursa and pain after aspiration, presence of nerve compression with neurological impairment, mechanical limitation to flexion, and extension of the elbow or biceps tendon degeneration and/or functional impairment.

Value of ultrasound before joint aspiration

OBJECTIVE

The purpose of this article is to illustrate and discuss the value of ultra-sound screening before joint aspiration.

CONCLUSION

Before joint aspiration, ultrasound assessment of the overlying and surrounding soft tissues requires little time and is relatively inexpensive. Bursal fluid collections, soft-tissue abscesses, and other fluid collections that would be undetected with fluoroscopy or blind aspiration can thus be identified. Ultrasound screening before joint aspiration can aid diagnosis and decrease the risk of iatrogenic complications.

Sonography of the bicipitoradial bursa: A short pictorial essay

Serous bursae consist of a synovial membrane enveloping a film of liquid. They are located at interfaces between moving structures where friction must be reduced. The bicipitoradial bursa lies between the distal tendon of the biceps brachii, which it surrounds, and the radial tuberosity. It is a relatively large bursa, with dimensions ranging from 2.4 to 3.9 cm. It sometimes presents septation. It does not communicate with the joint cavity, but it may communicate with the interosseous bursa of the elbow. Regardless of its cause, bicipitoradial bursitis presents as a mass in the cubital fossa and/or with neurological symptoms (sensorial and/or motorial) caused by compression of the radial nerve. On ultrasonography, the inflamed bursa is visualized as an anechoic formation surrounding the distal biceps tendon. In addition to its role in diagnosing the bursitis, sonography can provide information about radial nerve injury (in the presence of macroscopic damage), and it can also be used for guidance during intrabursal injections.

[Ultrasound guided interventional radiology]

Ultrasound is a valuable imaging technique for musculoskeletal pathology. It is increasingly used for image-guided procedures such as aspiration of superficial or deep collections, injection of drugs, or biopsies. Ultrasound guidance is an interesting alternative to procedures performed either blindly or under fluoroscopic or CT guidance. Advantages of US-guided procedures include the absence of ionizing radiation, real-time monitoring during needle placement, decreased risk of injury to neighboring structures (namely vessels and nerves), real time confirmation of procedure success (injection, drainage, biopsy). Minor inconveniences relate to the proper conditions for performance of ultrasound. Complications are rare and can be avoided by using proper sterile technique and evaluate for potential contra-indications to the procedure. As with any other image guided procedure, informed consent is required.

[Interventional sonography]

Diagnostic and therapeutic interventional procedures are rapidly expanding and, when guided by imaging, are more efficient then when performed with a blinded technique. Compared to fluoroscopy and CT, ultrasound does not utilize ionizing radiation. It can facilitate needle placement for arthrography, tenography or bursography or it can guide a variety of procedures such as aspiration, arthrocentesis, local steroid injections and needling of tendon calcifications. Technological improvements have increased the precision of ultrasound guidance and have contributed to reduce the risk of complication. Real time scanning allows simultaneous visualization of the target and of needle progression and has diminished the rate of complications, that are infrequent if the operator uses a strict sterile technique and respects the contraindications.
