Abstract (sommario):

Background Rotator cuff tears are common and not well-understood shoulder problems. Structural and mechanical inhomogeneity of the supraspinatus tendon complicates accurate prediction of risk of tear propagation and may affect appropriate clinical treatment. Hypothesis We propose that interactions between the supraspinatus and infraspinatus tendons are critical to load bearing at the glenohumeral joint and warrant investigation. Study Design Controlled laboratory study. Methods Principal strains in the infraspinatus tendon of cadaveric human shoulders were evaluated with increasing anterior fu

Abstract (sommario):

Introduction Shear wave elastography ultrasound is a relatively new technique that evaluates the tissue elasticity by applying an acoustic radiation force impulse. It is undetermined how reliable this modality is in assessing rotator cuff tendons. The aim of this study, therefore, was to evaluate the reliability of shear wave elastography ultrasound to assess the stiffness of normal and tendinopathic supraspinatus tendons. Methods An inter- and intra-rater reliability trial was carried out using shear wave elastography to assess the supraspinatus tendon at its distal insertion, by measuring sh

Abstract (sommario):

Supraspinatus calcifying tendinosis is an uncommon finding in dogs. Although its radiographic appearance has been described previously, radiographs alone do not provide detailed information about the tendon parenchyma. Tendon ultrasonography has been widely applied for the diagnosis of human tendinosis, but it remains underused in dogs. This article reviews the ultrasonographic technique and variable appearance of canine supraspinatus calcifying tendinosis observed in 33 tendons. The ultrasonographic findings are described. The most common ultrasonographic finding was a hyperechoic area accomp

Summary. Bone density is an important factor that affects the strength of the suture of the tendons of the rotator cuff. The higher the bone density is, the greater is the strength of fixation of the supraspinatus tendon to the bone, since the anchor is more securely fixed in the bone. Objective: to determine the bone mineral density of the proximal humeral epiphysis in patients with partial tear of the supraspinatus tendon. Materials and Methods. An X-ray examination of 48 shoulder joints (24 with partial tear of the supraspinatus tendon and 24 intact contralateral) was performed

A methodology was developed for determining the compressive properties of the supraspinatus tendon, based on finite element principles. Simplified three-dimensional models were created based on anatomical thickness measurements of unloaded supraspinatus tendons over 15 points. The tendon material was characterized as a composite structure of longitudinally arranged collagen fibers within an extrafibrillar matrix. The matrix was formulated as a hyperelastic material described by the Ogden form of the strain energy potential. The hyperelastic material parameters were parametrically manipulated u

Abstract (sommario):

Chapter 37 discusses calcific hydroxyapatite deposition disease (HADD). Hydroxyapatite (HA) crystal deposition disease is a systemic disease of unknown etiology that is caused by periarticular and/or intraarticular deposition of HA crystals. The shoulder is the most commonly involved joint with calcification in the supraspinatus tendon, but not all patients with HADD are symptomatic. Radiography is the main diagnostic tool for HADD, which may show calcifications of varying size and shape in the periarticular tendons, bursae, and joint capsule with joint destruction. Ultrasound can be useful in evaluation and image-guided treatment of calcific tendinitis.

Abstract (sommario):

Non-invasive diagnostic imaging methods for diagnosis of pathological conditions is increasingly gaining popularity resulting from speedy and effective recovery during follow up in several clinical trials. The accuracy of the diagnosis depends on the experience and knowledge of physicians conducting the trial. In such scenario, the need for quantitative measures for details such as shape and size of tissue can assist physicians for better intuitive understanding of tissue and its pathologies. Computer aided diagnosis (CAD) tool incorporating methods for segmentation, texture analysis and area computation can increase the accuracy of diagnosis by providing quantitative analysis of the image. This chapter briefly describes issues and challenges for building the CAD tool followed by brief description about the methods involved. The methods are validation are also discussed briefly. To summarize the work, brief discussion about a new software or CAD tool for diagnosis of pathologies supraspinatus tendon with the help of ultrasound images is provided. The new software has an intuitive user interface which is easy, quick and suitable for medical work.

Abstract (sommario):

Tendon injuries and chronic pain, known as tendinopathy, are extremely common in supraspinatus and Achilles tendons. Despite their prevalence, the pathogenesis of these conditions is poorly understood. One of most common cited factors for injuries to the rotator cuff tendons is “impingement”, namely, mechanical compression of the supraspinatus tendon by the overlying coracoacromial arch [1]. To date, few studies have investigated the molecular processes underlying this condition.

Abstract (sommario):

Rotator cuff tendon tears are common conditions which can lead to significant pain and dysfunction. Tears may progress over time from isolated supraspinatus tears to complete ruptures of both the supraspinatus and infraspinatus tendons, disrupting the anterior-posterior force balance provided by the subscapularis anteriorly and infraspinatus posteriorly (commonly referred to as a “force couple”) [1]. This disruption may lead to increased joint instability and result in altered glenohumeral translations which may cause damage to joint structures, such as articular cartilage and adjacent (intact

Abstract (sommario):

High localized stresses can develop at the interface between dissimilar materials; their attachment is therefore a major engineering challenge. During the development of the tendon-to-bone attachment (the “enthesis”), tendon transitions into fibrocartilage and then into mineralized fibrocartilage as it inserts into bone [1,2]. While natural development leads to a strong and tough enthesis, surgical reattachment and healing of tendon to bone often fails [3]. Thus, a better understanding of the developmental cues necessary for enthesis formation may help to navigate future repair and tissue engi

Tendon tissue is composed of collagen fibers in a hydrated proteoglycan matrix. Although many tendons have fibers that are highly aligned (e.g. flexor tendon), the supraspinatus tendon (SST) of the shoulder has significant distribution of fiber alignment [1]. The alignment and distribution of the fibers likely contributes to the nonlinear and anisotropic mechanical behavior, however this has not been demonstrated. Understanding the role of fiber structure on tendon mechanical behavior, that is, characterizing the structure-function relationships, is critical to evaluate the function of injured

Abstract (sommario):

Rotator cuff tendon tears are common conditions which can alter shoulder joint function and over time, cause secondary damage to the surrounding tissues, including the cartilage and other remaining tendons. Glenohumeral joint stability is dependent on a dynamic balance between rotator cuff forces, in particular the subscapularis anteriorly and the infraspinatus posteriorly. An intact rotator cuff stabilizes the joint, allowing for concentric rotation of the humeral head on the glenoid. However, a massive rotator cuff tear involving the supraspinatus and infraspinatus may disrupt the normal bal
