The myotendinous junction (MTJ) is the weakest element in the muscle-tendon unit of the heel, and thus the most susceptible to injuries. The scarcity of adequate treatments means that tendinitis is a major concern to athletes and other groups who depend on their physical fitness, although green tea and glycine have both been shown to have beneficial effects on the inflammation. The present study investigated the remodeling effects of green tea and glycine in the MTJ of rats with tendinitis. For this, male Wistar rats were divided into five groups: animals without tendinitis and animals with tendinitis; animals with tendinitis supplied with green tea; animals with tendinitis supplied with a glycine diet; animals with tendinitis supplied with a green tea and glycine diet...

A 73-year-old woman presented with a 12-month history of a tender first dorsal extensor compartment of her right wrist along with swelling which extended proximally. Caring for her grandchildren exacerbated her pain, and rest relieved it. Over a 2-month period, two injections and splint immobilization failed to provide pain relief and swelling reduction. An ultrasound showed anomalous muscles within the first dorsal extensor compartment. Surgical release of the first compartment showed the abductor pollicis longus and extensor pollicis brevis tendons flanked by muscles within an inflamed sheath...

CONTEXT: In active individuals with femoroacetabular impingement (FAI), the resultant reduction in functional range of motion leads to high impaction loads at terminal ranges. These increased forces result in compensatory effects on bony and soft tissue structures within the hip joint and hemipelvis. An algorithm is useful in evaluating athletes with pre-arthritic, mechanical hip pain and associated compensatory disorders. EVIDENCE ACQUISITION: A literature search was performed by a review of PubMed articles published from 1976 to 2013...

Musculoskeletal ultrasound (US) is an excellent tool to diagnose muscle, tendon and ligament injuries, cystic structures and peripheral nerve compression, as well as soft tissue masses, without the risk of ionizing radiation. Musculoskeletal US is now routinely used by a growing number of rheumatology and sports medicine centres throughout UK. In standard clinical practice, US has an extremely useful application in differentiating fluid from soft tissue and identifying the severity of joint inflammation. The work described in this article was carried out to assess patients' feedback regarding the use of US guidance for intra-articular injections and/or the removal of fluid from their inflamed knee joints in a nurse-led clinic...

BACKGROUND: Multiple authors have debated the contribution of intertubercular groove morphology to biceps tendon pathology. It has been proposed that the shallow groove, combined with the supertubercular ridge of Meyer, predisposes patients to bicipital disease. In this study we hypothesized that there would be a correlation between bicipital groove morphology and the intraoperative finding of biceps pathology. METHODS: Seventy-five consecutive patients (average age of 63) undergoing arthroscopic rotator cuff repair surgery had their biceps tendons and intertubercular groove morphologies prospectively evaluated on closed MRI T1 axial cut images...

Impingement of the iliopsoas muscle after total hip arthroplasty is a potential cause of postoperative groin pain. In addition, hematoma within the iliopsoas sheath has been documented as a cause of groin pain in patients on long-term anticoagulation. We present the case of a patient on long-term anticoagulation presenting after total hip arthroplasty with recurrent, symptomatic iliopsoas sheath hematomas. We believe this was due to iliopsoas impingement caused by a malpositioned acetabular component. His pain was relieved after revision of the acetabular component and debridement of the inflamed psoas tendon...

Rotator cuff injuries in sports are usually a result of microtrauma from repetitive movements. Classic, or primary, impingement results directly from overhead motions, and secondary impingement is related to underlying shoulder instability. A variety of physical maneuvers are used to assess pain, muscle weakness, and shoulder stability. The workup also includes plain x-rays, supplemented by other imaging tests if a cuff tear is suspected. Nonoperative treatment, which may include steroid injections, is often effective for an inflamed rotator cuff tendon...

Iliotibial band (ITB) syndrome is regarded as an overuse injury, common in runners and cyclists. It is believed to be associated with excessive friction between the tract and the lateral femoral epicondyle-friction which 'inflames' the tract or a bursa. This article highlights evidence which challenges these views. Basic anatomical principles of the ITB have been overlooked: (a) it is not a discrete structure, but a thickened part of the fascia lata which envelops the thigh, (b) it is connected to the linea aspera by an intermuscular septum and to the supracondylar region of the femur (including the epicondyle) by coarse, fibrous bands (which are not pathological adhesions) that are clearly visible by dissection or MRI and (c) a bursa is rarely present-but may be mistaken for the lateral recess of the knee...

Magnetic resonance (MR) images of the right tarsal joint of 22 normal male Han:Wistar rats were acquired using a 4.7 T magnet. An intermediate-high signal area associated with the tendon of the flexor hallus longus muscle was noticed in three rats on T2-weighted images. These areas appeared as an intermediate-high signal on lightly T2-weighted images, but appeared as an iso-signal to muscle structure on proton density weighted images. Histology preparations showed that such areas were caused by a sizable fluid collection within the synovial sheath of the tendon of the flexor hallus longus muscle, with all other joint structures appearing normal...

Lower extremity soft tissue injuries and overuse conditions are frequently encountered among athletes. Muscles are frequently strained or contused, arteries and nerves can become entrapped, and tendons and bursae can become inflamed. Familiarity with the anatomy of the involved area is essential for making the correct diagnosis. The majority of these conditions can be accurately diagnosed based on a thorough history and physical examination alone, without the need for expensive imaging or invasive tests. Most of these conditions can be successfully managed conservatively, avoiding surgical intervention...

Different connective tissue cells secrete different types of tenascins. These glycoproteins contribute to extracellular matrix (ECM) structure and influence the physiology of the cells in contact with the tenascin containing environment. Tenascin-C expression is regulated by mechanical stress. It shows highest expression in connective tissue surrounding tumors, in wounds and in inflamed tissues where it may regulate cell morphology, growth, and migration by activating diverse intracellular signalling pathways...

PURPOSE: This study examines data from pharmaceutical, physical, and visual tests that support the possible diagnosis of presumed extraocular myositis and tendonitis (PEM-T). METHOD: The presence of ocular pain derived from inflamed extraocular musculature and tendons in 60 subjects with PEM-T was detected by palpating their globes near the eye muscle insertions. The pain sensations were subjectively rated and recorded. Because the sensation of pain elicited by such palpation was most-often unilateral, the study compares the affected sidewith pain to the side tha exhibited vision disturbance during the Turville Infinity Binocular Balance (TIB) test...

OBJECTIVE: Rheumatoid arthritis (RA) is an autoimmune disorder of unknown etiology characterized by symmetric, erosive synovitis and sometimes multisystem involvement. It affects 1% of the adult population and exhibits a chronic fluctuating course which may result in progressive joint destruction, deformity, disability and premature death. We review the literature data relative to the peculiar pathologic features of the disease shown by diagnostic imaging techniques. METHODS: All our patients were classified according to the diagnostic criteria of the American Rheumatism Association (1987)...

The appearance of gouty tophus in magnetic resonance imaging (MRI) is characteristic. On T1- and T2-weighted SE images, the signal intensity of tophaceous lesions is similar to that of muscles. According to the histology, T2-weighted SE images demonstrate extremely hyperintense signals, which reflect the high protein content in the amorphous center of the tophus. The microscopic urate crystals deposited there have no MRI signal and are of no further diagnostic impact. Vascularized granulation tissue surrounding the tophus center enhance after intervenous application of contrast agents (Gadolinium)...

Four groups of mdx mice (deflazacort, high dose of 1.5 mg/kg and low dose of 0.75 mg/kg; prednisone, 1.0 mg/kg; and a placebo) were examined in a double-blind protocol. The experiments tested the hypothesis that infrared spectroscopy can distinguish among gastrocnemius muscle tissues derived from dystrophic animals (n = 22) from different treatment groups and from control muscle tissue (n = 23). Results showed that muscle, inflamed muscle, and tendon can be distinguished on the basis of their infrared absorption patterns...

The medial intraarticular dislocation of the biceps tendon of the shoulder is a rare pathologic condition and its diagnosis before surgery is very important to properly repair the tears of rotator cuff tendons, the rotator cuff being nearly always involved. We report our experience in 8 patients (1.8%) with biceps tendon dislocation observed in a series of 432 patients submitted to MR studies to address several diagnostic issues. The MR patterns of biceps tendon dislocation and the related physiopathologic mechanisms are discussed...

Iliopsoas tendinitis is a common injury in sport. Despite of this there are only a few articles in the literature that deal with these injuries. The changes in the inflamed tendons and muscles have been difficult to determine objectively. The modernization of ultrasound devices has improved the methods of examination and made it possible to diagnose objective changes in the tendons and muscles. Recommendations for the treatment of acute and chronic iliopsoas tendinitis are given.

A 36-year-old female was admitted to hospital for debridement of chronically inflamed tendon sheaths and adjacent tissues near the left ankle. Despite antibiotic therapy and initial surgical interventions, the inflammation had progressed slowly over 16 months. Histopathological examination of excised tissues in September 1973 revealed a chronic granulomatous inflammation of tendon sheaths and muscle. Many branched hyphal segments, intercalary swollen cells, and a few conidia-like bodies were seen in sections, and also in KOH- and PAS-stained slides prepared from homogenized tissues...

Semimembranosus tenosynovitis is a common knee problem in the over-50 age-group, occurring mainly in women. It affects the reflected portion of the tendon of the semimembranosus muscle as well as the bursa below it. The tendon becomes inflamed as a result of friction at the entrance to the bony canal (semimembranosus groove), especially if osteophytes are present on the edges of the groove. Conservative treatment includes anti-inflammatory drugs, ultrasound, and friction massage. If necessary, nonresponders may be given local injection of 40-80 mg methylprednisolone acetate with 1% Xylocaine...
