Calcifying tendinopathies of the rotator cuff that do not respond to conservative treatment may require arthroscopic removal. Intraoperative localization of calcifications can be difficult and is usually performed by bursal needle probing. We present a surgical technique combining arthroscopy and intraoperative ultrasonography based on the ultrasound-guided needle technique to precisely and rapidly locate even small calcium deposits.

Acetic acid has become more commonly used in orthopaedic surgery. The purposed roles include biofilm eradication and surgical debridement, postoperative scar reduction and managing soft tissue injuries. Current research is scarce and does not provide conclusive evidence behind acetic acid's efficacy in orthopaedic procedures such as biofilm eradication or acetic acid iontophoresis in soft tissue injuries.

The medial collateral ligament (MCL) of the knee is a commonly injured ligament structure. Calcification of the MCL is very infrequent, benign, related to metabolic disorders and is a consequence of the deposition of calcium hydroxyapatite in the periarticular region. The clinical, histological and radiological picture of calcific tendonitis is defined and the etiology is multifactorial. Read More

Migration of calcification within the bone leading to greater tuberosity osteolysis is a peculiar complication of the calcifying tendinitis of the rotator cuff. The case of a 38-year-old woman complaining of right shoulder pain, which had been going on for one year, is hereby described. The evolution of the infraspinatus tendon calcifying tendinitis leading to osteolysis of the greater tuberosity of the humerus is depicted by imaging and, particularly, by the MR and CT features changing over time.

The radiographic appearance of calcific tendinitis of the rotator cuff varies according to the stage of the disease. We compared currently used classification systems in a large group of observers to identify the most reliable classification system. Thirty-seven orthopaedic surgeons evaluated shoulder radiographs of 25 patients to classify the stage of the calcific tendinitis according to the classifications by (1) Gärtner and (2) Molé on a Web-based study platform.

Purpose: The aim of this study is to evaluate clinical outcome for arthroscopic removal of calcium deposit without acromioplasty and rotator cuff repair for patients with ultrasound-diagnosed arch-shaped calcifying tendinitis of the rotator cuff (type I), homogenic (x-ray) with chronic pain.

Methods: We retrospectively reviewed 50 patients with homogenous, arch-shaped calcifying tendinitis, suffering from chronic pain and who underwent arthroscopic treatment and 50 patients with the same type of tendinitis treated conservatively. All patients had calcium deposit located in supraspinatus tendon, pre-operatively and post-operatively evaluated by ultrasound. Read More

Extracorporeal shock wave therapy (ESWT) is a safe therapy and there are only a few side effects known (such as pain during ESWT and minor haematomata), but no severe complications are to be expected if it is performed as recommended.Contraindications are severe coagulopathy for high-energy ESWT, and ESWT with focus on the foetus or embryo and focus on severe infection.The effect mechanism of ESWT is still a component of diverse studies, but as far as we can summarize today, it is a similar process to a cascade triggered by mechano-transduction: mechanical energy causes changes in the cellular skeleton, which provokes a reaction of the cell core (for example release of mRNA) to influence diverse cell structures such as mitochondria, endoplasmic reticulum, intracellular vesicles, etc. Read More

Objective: The goal of this article is the radiological visualization of the often very difficult pathoanatomical changes associated with calcifying tendinitis, which in rare cases may erode and ultimately invade the bone.

Materials And Methods: We investigated the diagnostic reliability of radiographs, magnetic resonance imaging (MRI) and computed tomography (CT) in 11 patients with calcifying tendinitis. Eight lesions were located in the upper (4 supraspinatus tendon, 2 deltoideus tendon, 1 pectoralis tendon, 1 biceps tendon) and 3 in the lower extremity (2 gluteus tendon, 1 adductor magnus tendon).

Background: Rotator cuff calcific tendinopathy (RCCT) is frequently diagnosed in patients with shoulder pain, but there is no consensus on its treatment such as rest, nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, subacromial corticosteroid injection (SAI), extracorporeal shock wave therapy (ESWT), and ultrasound-guided percutaneous lavage (UGPL). The aim of the study was to compare the effectiveness of UGPL with other techniques in the treatment of RCCT.

Methods: Literature searches of PubMed, EMBASE, OVID, Cochrane Library, Web of Science, Chinese Biomedical Literature, Wanfang, Weipu Journal, and CNKI databases were performed up to August 2018. Read More

The term "idiopathic calcifying tenosynovitis" (ICT) refers to a clinically and radiologically defined syndrome of pain and tendinous calcifications, most often involving the shoulder joint. A distinctive subset of ICT cases, termed "tenosynovitis with psammomatous calcifications" (TPC), occurs in the distal extremities and shows characteristic morphology, in particular psammomatous calcifications. As only 14 cases have been reported to date, TPC remains poorly recognized by both pathologists and clinicians. Read More

Purpose: Magnetic resonance (MRI) is a valuable imaging method which can detect pre-operative rotator cuff tear characteristics accurately. However, tendon degeneration almost always necessitates a certain amount of debridement during arthroscopic repair, which alters tear size and shape. The aim of this study is to question the accuracy of the pre-operative tear size and classification in MRI and its relation to the tear size and type of the debrided tendon during arthroscopic repair.

Calcifying tendinitis of the shoulder is characterized with the formation of the calcium deposits in tendon, which mostly involves supraspinatus. The formation of the calcium deposits may be related to the excessive mechanical stimulation and non-tenocytes generation from tendon stem cell. The disease is usually associated with pain, especially when activating the shoulder. Read More

However, individuals with diabetes have a heightened risk of musculoskeletal problems, including tendon pathologies. Diabetes has a significant impact on the function of tendons due to the accumulation of advanced glycation end-products in the load-bearing collagen. Read More

Background: Inflammatory and calcifying diseases of the soft tissues are disorders having significant economical and social repercussions. They can be treated with drugs or physical therapy, and if these fail, surgery used to be the last existing therapeutic step. In recent years, a non-surgical alternative is being used to treat them, the application of extracorporeal shock waves. Read More

We aim to describe imaging-guided (ultrasound and CT) interventional techniques in the musculoskeletal system that can be performed by general radiologists, whether in hospitals, primary care clinics, private offices, or other settings. The first requirement for doing these procedures is adequate knowledge of the anatomy of the musculoskeletal system. The second requirement is to inform the patient thoroughly about the technique, the risks involved, and the alternatives available in order to obtain written informed consent. Read More

Calcifying tendinitis occurs most commonly in the rotator cuff tendons, particularly involving the supraspinatus tendon insertion, and is often asymptomatic. Cortical erosion secondary to calcifying tendinitis has been reported in multiple locations, including in the rotator cuff tendons. The authors report two cases of symptomatic calcifying tendinitis involving the infraspinatus tendon with cortical erosion with correlative radiographic, and MR findings. Read More
