Incidence and causes of tenosynovitis of the wrist extensors in long distance paddle canoeists. (1/136)
OBJECTIVES: To investigate the incidence and causes of acute tenosynovitis of the forearm of long distance canoeists. METHOD: A systematic sample of canoeists competing in four canoe marathons were interviewed. The interview included questions about the presence and severity of pain in the forearm and average training distances. Features of the paddles and canoes were determined. RESULTS: An average of 23% of the competitors in each race developed this condition. The incidence was significantly higher in the dominant than the nondominant hand but was unrelated to the type of canoe and the angle of the paddle blades. Canoeists who covered more than 100 km a week for eight weeks preceding the race had a significantly lower incidence of tenosynovitis than those who trained less. Environmental conditions during racing, including fast flowing water, high winds, and choppy waters, and the paddling techniques, especially hyperextension of the wrist during the pushing phase of the stroke, were both related to the incidence of tenosynovitis. CONCLUSION: Tenosynovitis is a common injury in long distance canoeists. The study suggests that development of tenosynovitis is not related to the equipment used, but is probably caused by difficult paddling conditions, in particular uneven surface conditions, which may cause an altered paddling style. However, a number of factors can affect canoeing style. Level of fitness and the ability to balance even a less stable canoe, thereby maintaining optimum paddling style without repeated eccentric loading of the forearm tendons to limit hyperextension of the wrist, would seem to be important. (+info)Remitting seronegative symmetrical synovitis with pitting oedema (RS3PE) syndrome: a prospective follow up and magnetic resonance imaging study. (2/136)
OBJECTIVE: To determine the clinical characteristics of patients with "pure" remitting seronegative symmetrical synovitis with pitting oedema (RS3PE) syndrome, and to investigate its relation with polymyalgia rheumatica (PMR). Magnetic resonance imaging (MRI) was used to describe the anatomical structures affected by inflammation in pure RS3PE syndrome. METHODS: A prospective follow up study of 23 consecutive patients with pure RS3PE syndrome and 177 consecutive patients with PMR diagnosed over a five year period in two Italian secondary referral centres of rheumatology. Hands or feet MRI, or both, was performed at diagnosis in 7 of 23 patients. RESULTS: At inspection evidence of hand and/or foot tenosynovitis was present in all the 23 patients with pure RS3PE syndrome. Twenty one (12%) patients with PMR associated distal extremity swelling with pitting oedema. No significant differences in the sex, age at onset of disease, acute phase reactant values at diagnosis, frequency of peripheral synovitis and carpal tunnel syndrome and frequency of HLA-B7 antigen were present between patients with pure RS3PE and PMR. In both conditions no patient under 50 was observed, the disease frequency increased significantly with age and the highest frequency was present in the age group 70-79 years. Clinical symptoms for both conditions responded promptly to corticosteroids and no patient developed rheumatoid arthritis during the follow up. However, the patients with pure RS3PE syndrome were characterised by shorter duration of treatment, lower cumulative corticosteroid dose and lower frequency of systemic signs/symptoms and relapse/recurrence. Hands and feet MRI showed evidence of tenosynovitis in five patients and joint synovitis in three patients. CONCLUSION: The similarities of demographic, clinical, and MRI findings between RS3PE syndrome and PMR and the concurrence of the two syndromes suggest that these conditions may be part of the same disease and that the diagnostic labels of PMR and RS3PE syndrome may not indicate a real difference. The presence of distal oedema seems to indicate a better prognosis. (+info)Musculoskeletal manifestations in a population-based cohort of patients with giant cell arteritis. (3/136)
OBJECTIVE: To define musculoskeletal manifestations occurring in a population-based cohort of patients with giant cell (temporal) arteritis (GCA). METHODS: The records of 128 patients with GCA diagnosed over a 42-year-period (1950-1991) in Olmsted County, MN, were reviewed for the presence and type of musculoskeletal manifestations, their relationship to the onset and course of GCA, and their response to treatment. RESULTS: Fifty-three patients (41%) developed polymyalgia rheumatica: 23 before, 17 concurrently with, and 13 after the diagnosis of GCA. Thirty patients (23%) developed 1 or more peripheral musculoskeletal manifestations. These included peripheral synovitis in 23 patients (6 of whom fulfilled criteria for rheumatoid arthritis), distal extremity swelling with pitting edema in 13, distal swelling without pitting in 5, tenosynovitis in 6, and carpal tunnel syndrome in 2. Fifty-seven episodes of peripheral manifestations occurred in the 30 patients at different times during the course of GCA. In most, the onset of PMR and peripheral manifestations was within 2 years of the diagnosis of GCA. CONCLUSION: Musculoskeletal symptoms in GCA are common and varied. Most appear linked temporally to the underlying GCA, indicating that the nature of this illness and its clinical expression are broader than often considered. (+info)Comparison of sonography and magnetic resonance imaging for the diagnosis of partial tears of finger extensor tendons in rheumatoid arthritis. (4/136)
OBJECTIVE: Finger extensor tenosynovitis in rheumatoid arthritis (RA) may lead to partial and eventually to complete tendon tears. The aim of this study was to investigate the diagnostic value of sonography (SG) and/or magnetic resonance imaging (MRI) to visualize partial tendon tears. METHODS: Twenty-one RA patients with finger extensor tenosynovitis for more than 12 months underwent SG, MRI and surgical inspection, the latter being the gold standard. RESULTS: For partial tears, sensitivity and specificity were 0.27 and 0.83 for MRI, and 0.33 and 0.89 for SG, respectively. Positive and negative predictive values were 0.35 and 0.78 for MRI, and 0.50 and 0.80 for SG, respectively. Accuracy was 0.69 for MRI and 0.75 for SG. CONCLUSION: For visualization of partial finger extensor tendon tears in RA patients, SG performs slightly better than MRI, but both techniques are at present not sensitive enough to be used in daily practice. (+info)Mycobacterium terrae: case reports, literature review, and in vitro antibiotic susceptibility testing. (5/136)
Mycobacterium terrae infection can cause debilitating disease that is relatively resistant to antibiotic therapy. Two cases are presented, and data from an additional 52 reports from the literature are reviewed. Tenosynovitis of the upper extremity, often following trauma, was the most commonly reported presentation (59% of cases), with pulmonary disease occurring in an additional 26% of cases. Underlying medical problems were absent (44%) or not reported (28%) in 72% of the cases. One-half of the patients with upper extremity tenosynovitis were treated with local or systemic corticosteroids, before microbiological identification. Only one-half of the patients with tenosynovitis who were followed up for 6 months had clinical improvement or were cured. The other one-half of the patients required repeated debridement, tendon extirpation, or amputation. The best antimicrobial therapy for M. terrae infection is unknown but might include a macrolide antibiotic plus ethambutol and one other effective drug for at least 12 months after clinical response. Parenteral treatment with an aminoglycoside and surgery may be useful in selected cases. (+info)A retinacular sling for subluxing tendons of the first extensor compartment. A case report. (6/136)
Over-zealous release of the first dorsal compartment of the wrist for de Quervain's disease or other lesions such as ganglia, may result in volar subluxation of the tendons of abductor pollicis longus and extensor pollicis brevis. This is usually asymptomatic, but may occasionally become disabling. We describe an operation using part of the extensor retinaculum to stabilise such a subluxation. (+info)Magnetic resonance imaging, radiography, and scintigraphy of the finger joints: one year follow up of patients with early arthritis. The TIRA Group. (7/136)
OBJECTIVES: To evaluate synovial membrane hypertrophy, tenosynovitis, and erosion development of the 2nd to 5th metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints by magnetic resonance imaging in a group of patients with rheumatoid arthritis (RA) or suspected RA followed up for one year. Additionally, to compare the results with radiography, bone scintigraphy, and clinical findings. PATIENTS AND METHODS: Fifty five patients were examined at baseline, of whom 34 were followed up for one year. Twenty one patients already fulfilled the American College of Rheumatology (ACR) criteria for RA at baseline, five fulfilled the criteria only after one year's follow up, whereas eight maintained the original diagnosis of early unclassified polyarthritis. The following MRI variables were assessed at baseline and one year: synovial membrane hypertrophy score, number of erosions, and tenosynovitis score. RESULTS: MRI detected progression of erosions earlier and more often than did radiography of the same joints; at baseline the MRI to radiography ratio was 28:4. Erosions were exclusively found in patients with RA at baseline or fulfilling the ACR criteria at one year. At one year follow up, scores of MR synovial membrane hypertrophy, tenosynovitis, and scintigraphic tracer accumulation had not changed significantly from baseline; in contrast, swollen and tender joint counts had declined significantly (p<0.05). CONCLUSIONS: MRI detected more erosions than radiography. MR synovial membrane hypertrophy and scintigraphy scores did not parallel the changes seen over time in clinically assessed swollen and tender joint counts. Although joint disease activity may be assessed as quiescent by conventional clinical methods, a more detailed evaluation by MRI may show that a pathological condition is still present within the synovium. (+info)The outcome of treatment of trigger thumb in children. (8/136)
Our aim was to determine the outcome of the treatment of trigger thumb in children. There was a rate of spontaneous recovery of 49% in those children whose thumbs were observed before a final decision to operate was made. Spontaneous recovery occurred more commonly in children over 12 months old. All patients treated by operation had a satisfactory outcome with few complications. The overall rate of recurrence was 4.0% and it was more common in younger children. Our results suggest that a conservative approach to surgery for this condition could be adopted. (+info)Tenosynovitis is a medical condition characterized by inflammation of the lining (synovium) surrounding a tendon, which is a cord-like structure that attaches muscle to bone. This inflammation can cause pain, swelling, and difficulty moving the affected joint. Tenosynovitis often affects the hands, wrists, feet, and ankles, and it can result from various causes, including infection, injury, overuse, or autoimmune disorders like rheumatoid arthritis. Prompt diagnosis and treatment of tenosynovitis are essential to prevent complications such as tendon rupture or chronic pain.
De Quervain disease, also known as De Quervain tenosynovitis, is a medical condition that affects the tendons on the thumb side of the wrist. It is characterized by the inflammation and thickening of the sheath that surrounds these tendons, leading to pain and difficulty in moving the thumb and wrist.
The exact cause of De Quervain disease is not known, but it is often associated with repetitive hand or wrist movements, especially those that involve twisting or gripping. It can also occur after an injury to the wrist or thumb. The condition is more common in middle-aged women, and may be related to hormonal changes during pregnancy or menopause.
The symptoms of De Quervain disease include pain and tenderness on the thumb side of the wrist, which may worsen with movement or gripping activities. There may also be swelling and a creaking or crackling sensation when moving the thumb and wrist. Diagnosis is typically made based on the patient's symptoms and a physical examination, although imaging tests such as ultrasound or MRI may be used to confirm the diagnosis.
Treatment for De Quervain disease usually involves resting the affected area, avoiding activities that aggravate the symptoms, and using ice packs to reduce swelling. In some cases, immobilization with a splint or brace may be recommended to allow the tendons to heal. Anti-inflammatory medications or corticosteroid injections may also be used to reduce pain and inflammation. Surgery may be considered if other treatments are not effective.
The wrist joint, also known as the radiocarpal joint, is a condyloid joint that connects the distal end of the radius bone in the forearm to the proximal row of carpal bones in the hand (scaphoid, lunate, and triquetral bones). It allows for flexion, extension, radial deviation, and ulnar deviation movements of the hand. The wrist joint is surrounded by a capsule and reinforced by several ligaments that provide stability and strength to the joint.
Tendon entrapment is a medical condition that occurs when a tendon, a cord-like structure that attaches muscle to bone, becomes compressed or irritated as it passes through a narrow tunnel or canal in the body. This compression can cause pain, swelling, and difficulty moving the affected joint.
Tendon entrapment is often caused by repetitive motion or overuse, which can lead to inflammation and thickening of the tendon. In some cases, the tendon may become entrapped due to a structural abnormality, such as a bone spur or a ganglion cyst.
Common examples of tendon entrapment include:
* Carpal tunnel syndrome, which is caused by compression of the median nerve and flexor tendons in the wrist
* De Quervain's tenosynovitis, which affects the tendons on the thumb side of the wrist
* Tarsal tunnel syndrome, which involves compression of the posterior tibial nerve and tendon in the ankle
Treatment for tendon entrapment typically involves rest, immobilization, physical therapy, and anti-inflammatory medications. In severe cases, surgery may be necessary to release the entrapped tendon and relieve pressure.
A medical definition of the wrist is the complex joint that connects the forearm to the hand, composed of eight carpal bones arranged in two rows. The wrist allows for movement and flexibility in the hand, enabling us to perform various activities such as grasping, writing, and typing. It also provides stability and support for the hand during these movements. Additionally, numerous ligaments, tendons, and nerves pass through or near the wrist, making it susceptible to injuries and conditions like carpal tunnel syndrome.
A finger joint, also known as an articulation, is the point where two bones in a finger connect and allow for movement. The majority of finger joints are classified as hinge joints, permitting flexion and extension movements. These joints consist of several components:
1. Articular cartilage: Smooth tissue that covers the ends of the bones, enabling smooth movement and protecting the bones from friction.
2. Joint capsule: A fibrous sac enclosing the joint, providing stability and producing synovial fluid for lubrication.
3. Synovial membrane: Lines the inner surface of the joint capsule and produces synovial fluid to lubricate the joint.
4. Volar plate (palmar ligament): A strong band of tissue located on the palm side of the joint, preventing excessive extension and maintaining alignment.
5. Collateral ligaments: Two bands of tissue located on each side of the joint, providing lateral stability and limiting radial and ulnar deviation.
6. Flexor tendons: Tendons that attach to the bones on the palmar side of the finger joints, facilitating flexion movements.
7. Extensor tendons: Tendons that attach to the bones on the dorsal side of the finger joints, enabling extension movements.
Finger joints are essential for hand function and enable activities such as grasping, holding, writing, and manipulating objects.
Tennis Elbow, also known as Lateral Epicondylitis, is a common cause of pain on the outside (lateral) part of the elbow. It's an overuse injury that causes inflammation and microtears in the tendons that attach to the bony prominence (epicondyle) on the outer side of the elbow, specifically where the extensor carpi radialis brevis muscle tendon inserts. Despite its name, this condition is not limited to tennis players; it can occur in any activity that involves repetitive and forceful gripping or wrist extension, such as painting, plumbing, cooking, or using tools. Symptoms often include pain and tenderness on the outer elbow, weakened grip strength, and sometimes radiating pain down the forearm.
Osteoarticular tuberculosis is a form of extrapulmonary tuberculosis (TB) that involves the bones and joints. It is caused by the bacterium Mycobacterium tuberculosis. The infection can spread to the bones and joints through the bloodstream or from nearby infected organs, such as the lungs.
The most commonly affected sites are the spine (Pott's disease), hip, knee, wrist, and small bones of the hands and feet. Symptoms may include pain, swelling, stiffness, and decreased range of motion in the affected joint or bone. In some cases, the infection can lead to deformity, chronic disability, or even death if left untreated.
Diagnosis typically involves a combination of medical history, physical examination, imaging studies (such as X-rays, CT scans, or MRI), and laboratory tests (such as blood tests, sputum cultures, or biopsy). Treatment usually consists of a long course of antibiotics (usually for at least six months) to kill the bacteria. Surgery may also be necessary in some cases to remove infected tissue or stabilize damaged joints.
A tendon is the strong, flexible band of tissue that connects muscle to bone. It helps transfer the force produced by the muscle to allow various movements of our body parts. Tendons are made up of collagen fibers arranged in parallel bundles and have a poor blood supply, making them prone to injuries and slow to heal. Examples include the Achilles tendon, which connects the calf muscle to the heel bone, and the patellar tendon, which connects the kneecap to the shinbone.
"Mycobacterium marinum" is a slow-growing, gram-positive bacterium that belongs to the group of nontuberculous mycobacteria (NTM). It is commonly found in fresh and saltwater environments, including aquariums and swimming pools. This pathogen can cause skin infections, known as swimmer's granuloma or fish tank granuloma, in individuals who have exposure to contaminated water. The infection typically occurs through minor cuts or abrasions on the skin, leading to a localized, chronic, and slowly progressive lesion. In some cases, disseminated infection can occur in people with weakened immune systems.

Synovitis is a medical condition characterized by inflammation of the synovial membrane, which is the soft tissue that lines the inner surface of joint capsules and tendon sheaths. The synovial membrane produces synovial fluid, which lubricates the joint and allows for smooth movement.
Inflammation of the synovial membrane can cause it to thicken, redden, and become painful and swollen. This can lead to stiffness, limited mobility, and discomfort in the affected joint or tendon sheath. Synovitis may occur as a result of injury, overuse, infection, or autoimmune diseases such as rheumatoid arthritis.
If left untreated, synovitis can cause irreversible damage to the joint and surrounding tissues, including cartilage loss and bone erosion. Treatment typically involves a combination of medications, physical therapy, and lifestyle modifications to reduce inflammation and manage pain.
The metacarpophalangeal (MCP) joint is the joint that connects the bones of the hand (metacarpals) to the bones of the fingers and thumb (phalanges). It's also commonly referred to as the "knuckle" joint. The MCP joint allows for flexion, extension, abduction, and adduction movements of the fingers and thumb. It is a synovial joint, which means it contains a lubricating fluid called synovial fluid that helps reduce friction during movement.
Forearm injuries refer to damages or traumas that affect the anatomy and function of the forearm, which is the area between the elbow and wrist. This region consists of two long bones (the radius and ulna) and several muscles, tendons, ligaments, nerves, and blood vessels that enable movements such as flexion, extension, pronation, and supination of the hand and wrist.
Common forearm injuries include:
1. Fractures: Breaks in the radius or ulna bones can occur due to high-energy trauma, falls, or sports accidents. These fractures may be simple (stable) or compound (displaced), and might require immobilization, casting, or surgical intervention depending on their severity and location.
2. Sprains and Strains: Overstretching or tearing of the ligaments connecting the bones in the forearm or the muscles and tendons responsible for movement can lead to sprains and strains. These injuries often cause pain, swelling, bruising, and limited mobility.
3. Dislocations: In some cases, forceful trauma might result in the dislocation of the radioulnar joint, where the ends of the radius and ulna meet. This injury can be extremely painful and may necessitate immediate medical attention to realign the bones and stabilize the joint.
4. Tendonitis: Repetitive motions or overuse can cause inflammation and irritation of the tendons in the forearm, resulting in a condition known as tendonitis. This injury typically presents with localized pain, swelling, and stiffness that worsen with activity.
5. Nerve Injuries: Direct trauma, compression, or stretching can damage nerves in the forearm, leading to numbness, tingling, weakness, or paralysis in the hand and fingers. Common nerve injuries include radial nerve neuropathy and ulnar nerve entrapment.
6. Compartment Syndrome: Forearm compartment syndrome occurs when increased pressure within one of the forearm's fascial compartments restricts blood flow to the muscles, nerves, and tissues inside. This condition can result from trauma, bleeding, or swelling and requires immediate medical intervention to prevent permanent damage.
Accurate diagnosis and appropriate treatment are crucial for managing forearm injuries and ensuring optimal recovery. Patients should consult with a healthcare professional if they experience persistent pain, swelling, stiffness, weakness, or numbness in their forearms or hands.
I'm sorry for any confusion, but "Sports Equipment" is not a term that typically has a medical definition. It generally refers to the physical items or gear used in sports and athletic activities, such as balls, bats, helmets, protective pads, etc. If you're looking for a term related to sports that has a medical definition, I'd be happy to help with that!
Tendinopathy is a general term referring to the degeneration or dysrepair of a tendon, which can result in pain and impaired function. It was previously referred to as tendinitis or tendinosis, but tendinopathy is now preferred because it describes various pathological conditions within the tendon, rather than a specific diagnosis.
Tendinopathy often develops due to overuse, repetitive strain, or age-related wear and tear. The condition typically involves collagen breakdown in the tendon, along with an increase in disorganized tenocytes (tendon cells) and vascular changes. This process can lead to thickening of the tendon, loss of elasticity, and the formation of calcium deposits or nodules.
Commonly affected tendons include the Achilles tendon, patellar tendon, rotator cuff tendons in the shoulder, and the extensor carpi radialis brevis tendon in the elbow (also known as tennis elbow). Treatment for tendinopathy often includes rest, physical therapy, exercise, pain management, and occasionally, surgical intervention.
Nontuberculous Mycobacterium (NTM) infections refer to illnesses caused by a group of bacteria called mycobacteria that do not cause tuberculosis or leprosy. These bacteria are commonly found in the environment, such as in water, soil, and dust. They can be spread through inhalation, ingestion, or contact with contaminated materials.
NTM infections can affect various parts of the body, including the lungs, skin, and soft tissues. Lung infections are the most common form of NTM infection and often occur in people with underlying lung conditions such as chronic obstructive pulmonary disease (COPD) or bronchiectasis. Symptoms of NTM lung infection may include cough, fatigue, weight loss, fever, and night sweats.
Skin and soft tissue infections caused by NTM can occur through direct contact with contaminated water or soil, or through medical procedures such as contaminated injections or catheters. Symptoms of NTM skin and soft tissue infections may include redness, swelling, pain, and drainage.
Diagnosis of NTM infections typically involves a combination of clinical symptoms, imaging studies, and laboratory tests to identify the specific type of mycobacteria causing the infection. Treatment may involve multiple antibiotics for an extended period of time, depending on the severity and location of the infection.
In medical terms, a hand is the part of the human body that is attached to the forearm and consists of the carpus (wrist), metacarpus, and phalanges. It is made up of 27 bones, along with muscles, tendons, ligaments, and other soft tissues. The hand is a highly specialized organ that is capable of performing a wide range of complex movements and functions, including grasping, holding, manipulating objects, and communicating through gestures. It is also richly innervated with sensory receptors that provide information about touch, temperature, pain, and proprioception (the sense of the position and movement of body parts).
Trigger finger, also known as stenosing tenosynovitis, is a condition where one of the fingers or thumbs becomes stuck in a bent position and then straightens with a snap, much like pulling and releasing the trigger on a gun. The ring finger is most commonly affected, but it can occur in other fingers and thumbs as well.
In this disorder, the tendon sheath that surrounds the flexor tendons in the finger becomes inflamed and thickened, making it difficult for the tendon to glide smoothly through it. This results in the finger catching or locking in a bent position, which can be painful to straighten out.
The exact cause of trigger finger is not always known, but it is more common in women than men, and people with certain medical conditions such as diabetes and rheumatoid arthritis are at higher risk. Treatment options may include rest, splinting, medication, or surgery, depending on the severity of the condition.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Tendon injuries, also known as tendinopathies, refer to the damage or injury of tendons, which are strong bands of tissue that connect muscles to bones. Tendon injuries typically occur due to overuse or repetitive motion, causing micro-tears in the tendon fibers. The most common types of tendon injuries include tendinitis, which is inflammation of the tendon, and tendinosis, which is degeneration of the tendon's collagen.
Tendon injuries can cause pain, swelling, stiffness, and limited mobility in the affected area. The severity of the injury can vary from mild discomfort to severe pain that makes it difficult to move the affected joint. Treatment for tendon injuries may include rest, ice, compression, elevation (RICE) therapy, physical therapy, medication, or in some cases, surgery. Preventing tendon injuries involves warming up properly before exercise, using proper form and technique during physical activity, gradually increasing the intensity and duration of workouts, and taking regular breaks to rest and recover.
