An enthesopathy refers to a disorder involving the attachment of a tendon or ligament to a bone. [1] This site of attachment is known as the enthesis (pl. entheses). If the condition is known to be inflammatory, it can more precisely be called an enthesitis.

Enthesopathy of the pelvis likely due to ankylosing spondylitis

Enthesopathy can occur at the shoulder, elbow, wrist, carpus, hip, knee, ankle, tarsus, or heel bone, among other regions. Enthesopathies may take the form of spondyloarthropathies (joint diseases of the spine) such as ankylosing spondylitis, or psoriatic arthritis, plantar fasciitis, and Achilles tendinitis. Further examples include:[ citation needed ]

Causes

Generalized involvement of the entheses with calcification of tendon and ligament insertions and of joint capsules has been found for example in people with X-linked hypophosphatemic rickets. [2]

Diagnosis

Mainly by clinical examination and provocative tests by counteracting the muscle action.[ citation needed ]

Treatment

The natural history of the two most common enthesopathies (plantar fasciitis and lateral epicondylitis-both mislabeled as inflammatory) is resolution over a period of about one year without treatment.

There are no known disease-modifying treatments for these enthesopathies. In other words, there is no experimental evidence that any treatment can alter the pathophysiology (mucoid degeneration) or the duration of symptoms. There is no evidence that activity modification alters the natural history of the disease.

To date, all treatments are palliative. The evidence suggests that most treatments have non-specific effects (e.g. placebo effect, regression to the mean, self-limiting course of symptoms).

Injection of corticosteroid, platelet-rich plasma, stem cells, and extracorporeal shockwave therapy are examples of treatments that are not supported by experimental evidence and remain open to debate.

Palliative treatments consist of stretching, analgesics, and padding (e.g. cushioned foot wear for plantar fasciitis), splints (e.g. tennis elbow strap), and other treatments. The concept that a calcified attachment can be removed surgically is highly debatable as these calcifications are a regular part of an enthesopathy. [3]

Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. The pain is typically worse with movement. It most commonly occurs around the shoulder, elbow, wrist, hip, knee, or ankle.

<span class="mw-page-title-main">Shoulder problem</span> Medical condition

Shoulder problems including pain, are one of the more common reasons for physician visits for musculoskeletal symptoms. The shoulder is the most movable joint in the body. However, it is an unstable joint because of the range of motion allowed. This instability increases the likelihood of joint injury, often leading to a degenerative process in which tissues break down and no longer function well.

<span class="mw-page-title-main">Achilles tendon</span> Tendon at the back of the lower leg

The Achilles tendon or heel cord, also known as the calcaneal tendon, is a tendon at the back of the lower leg, and is the thickest in the human body. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone. These muscles, acting via the tendon, cause plantar flexion of the foot at the ankle joint, and flexion at the knee.

<span class="mw-page-title-main">Bursitis</span> Inflammation of the bursae (sacs of synovial fluid in joints)

Bursitis is the inflammation of one or more bursae of synovial fluid in the body. They are lined with a synovial membrane that secretes a lubricating synovial fluid. There are more than 150 bursae in the human body. The bursae rest at the points where internal functionaries, such as muscles and tendons, slide across bone. Healthy bursae create a smooth, almost frictionless functional gliding surface making normal movement painless. When bursitis occurs, however, movement relying on the inflamed bursa becomes difficult and painful. Moreover, movement of tendons and muscles over the inflamed bursa aggravates its inflammation, perpetuating the problem. Muscle can also be stiffened.

<span class="mw-page-title-main">Plantar fascia</span> Aponeurosis of the sole of the foot

The plantar fascia or plantar aponeurosis is the thick connective tissue aponeurosis which supports the arch on the bottom of the foot. Recent studies suggest that the plantar fascia is actually an aponeurosis rather than true fascia. It runs from the tuberosity of the calcaneus forward to the heads of the metatarsal bones.

<span class="mw-page-title-main">Plantar fasciitis</span> Connective tissue disorder of the heel

Plantar fasciitis or plantar heel pain is a disorder of the plantar fascia, which is the connective tissue that supports the arch of the foot. It results in pain in the heel and bottom of the foot that is usually most severe with the first steps of the day or following a period of rest. Pain is also frequently brought on by bending the foot and toes up towards the shin. The pain typically comes on gradually, and it affects both feet in about one-third of cases.

<span class="mw-page-title-main">Diseases of the foot</span> Medical conditions affecting the human foot

Diseases of the foot generally are not limited, that is they are related to or manifest elsewhere in the body. However, the foot is often the first place some of these diseases or a sign or symptom of others appear. This is because of the foot's distance from the central circulation, the heart and its constant exposure to pressures from the ground and the weight of the body.

<span class="mw-page-title-main">Tennis elbow</span> Condition in which the outer part of the elbow becomes sore and tender

Tennis elbow, also known as lateral epicondylitis or enthesopathy of the extensor carpi radialis origin, is an enthesopathy of the origin of the extensor carpi radialis brevis on the lateral epicondyle. The outer part of the elbow becomes painful and tender. The pain may also extend into the back of the forearm. Onset of symptoms is generally gradual, although they can seem sudden and be misinterpreted as an injury. Golfer's elbow is a similar condition that affects the inside of the elbow.

A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function.

Adhesive capsulitis (AC), also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple directions. The shoulder itself, however, does not generally hurt significantly when touched. Muscle loss around the shoulder may also occur. Onset is gradual over weeks to months. Complications can include fracture of the humerus or biceps tendon rupture.

Nintendo thumb, also known as gamer's thumb and similar names, is a form of repetitive strain injury (RSI) caused by excessive playing of video games with the traditional Nintendo controller. This injury mainly occurs due to repeated thumb movements while playing video games. The symptoms can include blistering, paraesthesia, as well as swelling of the thumbs, though any finger can be affected. This can lead to stress on tendons, nerves, and ligaments in the hands, and further onto lateral epicondylitis, tendinitis, bursitis, and carpal tunnel syndrome. Similar injuries can occur with other gaming systems, such as PlayStation thumb from playing Sony PlayStation. The general recommendation for the treatment is to rest and stop the repetitive motion of the affected finger. In more severe and painful cases, using NSAIDs is also recommended.

<span class="mw-page-title-main">Calcific tendinitis</span> Disorder characterized by calcium deposits in a tendon

Calcific tendinitis is a common condition where deposits of calcium phosphate form in a tendon, sometimes causing pain at the affected site. Deposits can occur in several places in the body, but are by far most common in the rotator cuff of the shoulder. Around 80% of those with deposits experience symptoms, typically chronic pain during certain shoulder movements, or sharp acute pain that worsens at night. Calcific tendinitis is typically diagnosed by physical exam and X-ray imaging. The disease often resolves completely on its own, but is typically treated with non-steroidal anti-inflammatory drugs to relieve pain, rest and physical therapy to promote healing, and in some cases various procedures to breakdown and/or remove the calcium deposits.

<span class="mw-page-title-main">Calcific bursitis</span> Medical condition

Calcific bursitis refers to calcium deposits within the bursae. This most occurs in the shoulder area. The most common bursa for calcific bursitis to occur is the subacromial bursa. A bursa is a small, fluid-filled sac that reduces friction, and facilitates movements between its adjacent tissues. Inflammation of the bursae is called bursitis.
