Tenderness3
Body temperature was checked at 37.5°C. Examination of the left knee confirmed tenderness and erythema associated with a joint effusion. (biomedcentral.com)
Affected joints show inflammation with swelling, tenderness, warmth, and decreased range of motion (ROM). (medscape.com)
Other features may include: Swelling, bruising, or tenderness over the joint. (ribinjuryclinic.com)
Other unusual often described as atypical conditions affecting the SC joint include Sterno- costoclavicular hyperostosis (SCCH) a chronic inflammatory disorder which presents with erythema, swelling, and pain of the sternoclavicular joint. (ribinjuryclinic.com)

Weakness2
Stiffness refers to difficulty in moving a joint, but to patients, stiffness also may mean weakness, fatigue, or fixed limitation of motion. (msdmanuals.com)
It may begin with systemic features (eg, fever, malaise, arthralgias, and weakness) before the appearance of overt joint inflammation and swelling. (medscape.com)
Occur2
A compensatory and reducible hyperextension may occur at the MCP joint. (medscape.com)

Any movement of the humerus at the shoulder joint will almost always involve the glenohumeral joint but also the SC and AC joints. (openorthopaedicsjournal.com)
With the muscles covering these three bones the shoulder joint is stabilised and allows the shoulder girdle to move the arm in multiple directions. (ribinjuryclinic.com)
Deformity3
The severity of RA may fluctuate over time, but chronic RA most commonly results in the progressive development of various degrees of joint destruction, deformity, and a significant decline in functional status. (medscape.com)
This deformity occurs as a result of synovitis stretching or rupturing the PIP joint through the central extensor tendon, with concomitant volar displacement of the lateral bands. (medscape.com)
This deformity may be initiated either (a) by disruption of the extensor tendon at the DIP joint, with secondary shortening of the central extensor tendon and hyperextension of the PIP joint, or (b) by volar herniation of the PIP joint capsule due to weakening from chronic synovitis, with subsequent tightening of the lateral bands and central extensor tendon. (medscape.com)
and the scapula and underlying ribs - Scapulothoracic joint are important areas that can cause pain, swelling and dysfunction (problems with movement) that may present with a chest wall problem. (ribinjuryclinic.com)
Arthritis9
Some musculoskeletal disorders affect primarily the joints, causing arthritis. (msdmanuals.com)
Pain in Multiple Joints Joints may simply be painful (arthralgia) or also inflamed (arthritis). (msdmanuals.com)
Despite advances in antimicrobial and surgical therapy, septic arthritis remains a rheumatologic emergency that can lead to rapid joint destruction and irreversible loss of function. (biomedcentral.com)
Treatment for septic arthritis was undertaken, and arthroscopic lavage of the joint performed. (biomedcentral.com)
With non-traumatic problems as in inflammatory conditions, such as rheumatoid arthritis, pain be felt in other joints and is more chronic. (ribinjuryclinic.com)
Non-traumatic inflammatory conditions of the SC joint, include forms of arthritis such as osteoarthritis , a type of degenerative arthritis that tends to get worse with age. (ribinjuryclinic.com)
Other types of inflammatory arthritis such as rheumatoid arthritis , typically affecting a younger population can cause pain and swelling of the SC joint. (ribinjuryclinic.com)
Chest MRI of a rare cause of a SC joint pain and swelling associated with a form of inflammatory or rheumatic arthritis, tophaceous gout (blue arrow). (ribinjuryclinic.com)
Symptoms1
The clinician should focus on systemic and extra-articular symptoms as well as joint symptoms. (msdmanuals.com)
Inflammation2
Joint inflammation is usually accompanied by warmth, swelling (due to intra-articular fluid, or effusion), and uncommonly. (msdmanuals.com)
Most patients with RA have muscle atrophy from disuse, which is often secondary to joint inflammation. (medscape.com)
Chronic1
Osteoarthritis (OA) Osteoarthritis is a chronic arthropathy characterized by disruption and potential loss of joint cartilage along with other joint changes, including bone hypertrophy (osteophyte formation). (msdmanuals.com)
Tendons1
Hyperextension of the DIP joint occurs as the tendons shorten with time. (medscape.com)
Infection1
With a joint infection, there may be redness over the joint and you may have fever, chills, or night sweats. (ribinjuryclinic.com)
Clavicle1
The bony anatomy of the shoulder girdle consists of the scapula, clavicle and humerus, which articulates at the shoulder as theglenohumeral and acromioclavicular (AC) joints (Table 1 ). (openorthopaedicsjournal.com)
Destruction1
Joint and tendon destruction may lead to deformities such as ulnar deviation, boutonniere and swan-neck deformities , hammer toes , and, occasionally, joint ankylosis. (medscape.com)
It is the only joint that links the bones of the shoulder (and arm) to the axial skeleton (chest and spine bones). (ribinjuryclinic.com)
Pain4
11 Pain with cross-arm adduction can indicate acromioclavicular pathology. (aafp.org)
The clinician must determine whether pain is worse when first moving a joint or after prolonged use and whether it is present upon waking or develops during the day. (msdmanuals.com)
Joint pain can be referred from extra-articular structures or from other joints. (msdmanuals.com)
The most common symptom of an SC joint problem is pain. (ribinjuryclinic.com)
Muscles1
The rotator cuff provides the main stabilising structure for the glenohumeral joint and is made up of supraspinatus, infraspinatus, subscapularis and teres minor muscles. (openorthopaedicsjournal.com)
Small1
In general, the small joints of the hands and feet are affected in a relatively symmetric distribution. (medscape.com)
Common2
In adults, Staphylococcus aureus is the most common microorganism isolated from native joints. (biomedcentral.com)
Anterior SC joint dislocation is more common and is typically associated with a lump over SC joint. (ribinjuryclinic.com)
Musculoskeletal1
Some musculoskeletal disorders affect primarily the joints, causing arthritis. (msdmanuals.com)
Secondary1
This deformity may be initiated either (a) by disruption of the extensor tendon at the DIP joint, with secondary shortening of the central extensor tendon and hyperextension of the PIP joint, or (b) by volar herniation of the PIP joint capsule due to weakening from chronic synovitis, with subsequent tightening of the lateral bands and central extensor tendon. (medscape.com)
Disruption1
Osteoarthritis (OA) Osteoarthritis is a chronic arthropathy characterized by disruption and potential loss of joint cartilage along with other joint changes, including bone hypertrophy (osteophyte formation). (msdmanuals.com)
Include1
In prosthetic joints they also include lower-grade pathogens from skin. (enetmd.com)
Weakness1
Stiffness refers to difficulty in moving a joint, but to patients, stiffness also may mean weakness, fatigue, or fixed limitation of motion. (msdmanuals.com)
Clinical1
Urgent consultation with an orthopaedic surgeon is recommended: arthroscopic washout is usually recommended, although some cases can be managed by joint aspiration once or twice daily until clinical response is evident. (enetmd.com)
Diagnosis1
Many patients make a complete recovery, but joint damage is highly likely when the diagnosis is made late. (enetmd.com)
Determine2
The clinician must determine whether pain is worse when first moving a joint or after prolonged use and whether it is present upon waking or develops during the day. (msdmanuals.com)
Fluid is taken from the joint and is analysed to determine the presence of infection (see aspiration), and pus may be drained to help relieve pain. (enetmd.com)
