The enthesis is the point at which the connective tissue structures, such as a joint capsule, fascia, ligament, tendon, or muscle attach to the bone the term enthesopathy typically refers to a degenerated enthesis though when some doctors uses this term, they typically mean enthesitis (inflammation of the enthesis). The enthesis organ of the adult achilles tendon the enthesis itself is characterised by an enthesis fibrocartilage (ef) which is most prominent in the superior part of the attachment. In addition to being clinically recognised at the achilles enthesis and patellar tendon insertions, this pattern of disease is well recognised at the plantar fascia, the elbow epicondyles, other insertions about the knees, spinous processes of the vertebrae and at other sites, including the iliac crest. The attachment of the achilles tendon is part of an ‘enthesis organ’ that reduces stress concentration at the hard–soft tissue interface the organ also includes opposing sesamoid and periosteal fibrocartilages, a bursa and kager's fat pad. This refers to the role of the enthesis as the site of attachment of bones with tendons or ligaments relatedly, in muscle terminology , the insertion is the site of attachment at the end with predominant movement or action (opposite of the origin).
Enthesis insertion of a tendon or ligament into periosteum and underlying bone enthesis 1 the use of artificial material in the repair of a defect or deformity of . Iv improving tendon-to-bone healing through regenerative medicine strategies (funded by nih r01/r56 ar057836) 41-51 healing of tendon to bone does not reproduce the structural or compositional features of the healthy enthesis 42,44,52 (figure 5). Furthermore, in certain tendon is uniform over the entire enthesis, or that powerful pennate muscles, there may be many different parts of the enthesis bear the strain at small intramuscular tendons that attach it to the different positions of the joint bone, rather than a single discrete tendon. Tendon attaches to bone across a functionally graded interface, the enthesis a gradient of mineral content is believed to play an important role for dissipation of stress concentrations at .
Tendon is a highly organized connective tissue, capable of resisting high tensile strength while transmitting forces from muscle to bone the region where a tendon, ligament or joint capsule attaches to bone is the enthesis. Enthesis (plural: entheses) typically refers to the connective tissue where tendons, ligaments, or joint capsules attach to bonetwo types of entheses exist: fibrous entheses and fibrocartilaginous entheses. The enthesis progressively changes from tendon, to fibrocartilage, to calcified fibrocartilage, and finally bone however, these four zones are not recreated following surgical repair but rather the tendon is joined to the bone through alternating layers of fibrovascular scar tissue ( 18 , 41 , 49 , 78 ). The achilles tendon is the large cord-like structure at the back of the heel it connects the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneum) it . The enthesis is defined as the site of attachment of a tendon, ligament, joint capsule, or fascia to bone there are two major types: fibrous and fibrocartilaginous .
An enthesis is a piece of connective tissue that connects bone to ligament or tendon inflammation of the entheses is called enthesitis an abnormality of the entheses is called enthesopathy. The enthesis (plural entheses) is the connective tissue between tendon or ligament and bone  there are two types of entheses: fibrous entheses and fibrocartilaginous entheses . The insertion of the tendon into bone – the enthesis – is also a common site of pain —ligaments: ligaments attach one bone to another and thereby provide structural integrity to the skeleton injury to ligaments usually results from excessive force being applied.
Enthesitis achilles tendon achilles tendonitis (also known as achilles tendinopathy or achilles tenosynovitis) is the achilles tendon, normally caused by excessive . Objective to assess the accuracy and utility of magnetic resonance (mr) imaging in the detection and grading of pectoralis major muscle and tendon tears design and patients a retrospective review was carried out of 10 patients referred for mr imaging for suspected pectoralis muscle injury and . An enthesis is a point of attachment or insertion point of a sinew (tendon or ligament) to the bone this image shows the foot and the achilles enthesis or tendon insertion point in cartoon form. The enthesis in psoriatic arthritis d mcgonagle 1,2, the enthesis organ be-tween the tendon and the calcaneal bone, which is the avascu-lar region of maximal.
An enthesis is the insertion of a tendon, ligament, capsule, or fascia into bone3 these insertions are classified as either lagenous tendon or ligament fibers . The optimal time to start training may be longer than 96 hours after an acute patellar tendon enthesis injury for the best overall healing of the tendon enthesis 4 . Entheses: tendon and ligament attachment sites m benjamin1, healthy enthesis) it presents a physical barrier separating tendon/ligament ﬁbroblasts were .
Understanding tendon enthesis tissue engineering in order to aid in the advancement of treatments for reducing recovery time and increasing healing following tendon enthesis injury. The enthesis is the point where a tendon or ligament attaches to a bone it is differentiated from the tendon, ligament or bone by the mineralization of the collagen fibers that fuse with the bone itself. Multiscale structures of the tendon-to-bone enthesis at the macroscale (left), the tendon attaches to the bone with a splayed geometry leading to a large insertion area. Enthesitis is irritability of soft tissues (muscles, tendons or ligaments) where it enter into the bones it is caused by joint disease and is the main sign of spondyloarthritis.
The integration of tendon into bone occurs at a specialized interface known as the enthesis the fibrous tendon to bone enthesis is established through a structurally continuous gradient from uncalcified tendon to calcified bone the enthesis exhibits gradients in tissue organization classified into . Enthesitis enthesitis refers to inflammation of entheses, the site where ligaments or tendons insert into the bones common locations for enthesitis include the bottoms of the feet, the achilles' tendons, and the places where ligaments attach to the ribs, spine, and pelvis.
