Joint-specific prevalence of osteoarthritis of the hand. (1/30)

PURPOSE: To quantify the prevalence of radiographic hand osteoarthritis (OA) among a group of community-dwelling individuals. Joint-specific prevalence rates/100 of radiographic OA of the hand were quantified and reported by age, gender, and dominant hand. METHODS: Data from a community-based, longitudinal study designed to follow the natural history of OA were used. Participants were ambulatory men and women, ages 40 years and older, with and without radiographic hand OA (N = 3327). Bilateral hand OA was examined at three joints: second distal interphalangeal joints (DIP), third proximal interphalangeal joints (PIP), and first carpometacarpal joint of the thumb (CMC). The ordinal scale of Kellgren and Lawrence (0-4) was used to determine OA status (grades 2+). RESULTS: Radiographic hand OA status was determined for all persons in the study group comprised of 2302 women (69%) and 1025 men (31%). The sample sizes for the age groups (years) were 532 (40-49), 905 (50-59), 998 (60-69), 749 (70-79), and 143 (80+). Overall, the DIP joint demonstrated the highest OA prevalence, while the PIP joint showed the lowest prevalence. Joint-specific hand OA prevalence rates for second DIP, third PIP, and first CMC were 35%, 18%, and 21%, respectively. Expectedly, hand OA prevalence for all joints increased with age. With exceptions, women demonstrated higher hand OA prevalence rates for the three sites examined. However, among men aged 40-49, the second DIP joint OA rate was higher (13%) compared with women (8%). Additionally, men in that age group demonstrated an elevated first CMC joint OA rate (9%) compared with women (5%). Gender-specific hand dominance analyses demonstrated that the majority of individuals with unilateral second DIP or third PIP OA presented in their dominant hand. However, among those with unilateral first CMC OA, both genders displayed a tendency to present in their nondominant hand. CONCLUSION: These findings suggest the need for further investigation of the role gender can play in the development of hand OA in populations under 60 years of age. Additional epidemiological studies addressing hand OA will serve to bridge the gap between the current levels of knowledge about the knee and the hand. The disease burden of hand OA affects a large percentage of the population. Research efforts that more exhaustively characterize the prevalence of hand OA may contribute toward interventions that, ultimately, impact a rapidly growing segment of our population.  (+info)

Validity of self-report measures of pain and disability for persons who have undergone arthroplasty for osteoarthritis of the carpometacarpal joint of the hand. (2/30)

OBJECTIVE: To establish the validity of three self-report scales used to measure function following arthroplasty for osteoarthritis (OA) of the carpometacarpal joint. METHOD: Persons with OA of the carpometacarpal joint (n=122) were assessed on one occasion 9-117 months following tendon interposition arthroplasty. They completed three self-report measures of hand/upper limb disability: the Australian/Canadian Osteoarthritis Hand Index (AUSCAN), the Patient-Rated Wrist Hand Evaluation (PRWHE), and the Disabilities of Arm, Shoulder and Hand (DASH). They also completed the Short Form 36 (SF-36) and performed tests of strength, range of motion (ROM), and dexterity. Factor analysis and correlations were used to determine the association among the scales and subscales considered to measure similar constructs (e.g., pain and physical disability). Correlations between the scales and measures of impairment were also conducted to examine construct validity of the disability measures. t-Tests evaluated the hypotheses that subjects with isolated hand OA would have lower scores than those with additional joint involvement. RESULTS: All three scales or their subscales loaded on one factor. Convergent validity of the disability measures was demonstrated by high correlations between similar subscales (r>0.75), and divergent validity by a lack of correlation between the measures and self-report hand appearance. As expected, correlations between disability and strength, dexterity, or a global measure of ROM were higher than with ROM of individual joints. The AUSCAN and the DASH were better able to discriminate those with localized hand OA from those with involvement of other joints. CONCLUSIONS: The AUSCAN, PRWHE, and DASH are valid assessments of pain and/or disability of hand OA, and provide information distinct from impairment measures.  (+info)

Do metabolic factors add to the effect of overweight on hand osteoarthritis? The Rotterdam Study. (3/30)

BACKGROUND: As hand joints are non-weight bearing, the association between overweight and hand osteoarthritis (HOA) is critical to understanding how overweight may associate with osteoarthritis (OA) apart from axial load. Overweight might be associated with the occurrence of OA through other metabolic factors. AIM: To evaluate the role of overweight in HOA, cross-sectional data of a population-based study were used (> or =55 years, n = 3585). The role of diabetes, hypertension and total cholesterol:high-density lipoprotein (HDL)-cholesterol ratio on HOA, and whether they play an intermediate role in the association of overweight/HOA was investigated. Furthermore, the prevalence of HOA in the concurrent presence of overweight and other metabolic factors was evaluated. RESULTS: Independently of other metabolic factors, overweight (body mass index (BMI) >27.4 kg/m(2)) showed a significant association with HOA (OR 1.4, 95% CI 1.2 to 1.7). The association between diabetes and HOA was only present in people aged 55-62 years (OR 1.9, 95% CI 1.0 to 3.8), but was absent in the total population or in other age groups. The association of hypertension with HOA was weak, and disappeared after adjustment for BMI. The total/HDL cholesterol ratio showed no significant association with HOA. The concurrent presence of overweight, diabetes and hypertension resulted in an even higher prevalence of HOA (OR 2.3, 95% CI 1.3 to 3.9) compared with subjects with none of these characteristics; this prevalence increased further in the younger age group (OR 3.2, 95% CI 1.1 to 8.8). CONCLUSION: No intermediate effect of metabolic factors on the association of overweight with HOA was found. An increase in the prevalence of HOA, however, seems to be present when overweight occurs together with hypertension and diabetes especially at a relatively young age.  (+info)

Work-related bilateral osteoarthritis of the first carpometacarpal joints. (4/30)

BACKGROUND: A 44-year-old industrial worker produced panels for folding doors for 9 years. During this period, he developed osteoarthritis (OA) of both first carpometacarpal joints. Surgery was performed without improvement. METHODS: Clinical examination, demonstration and recording of work conditions, with photos and videos. The literature concerning first carpometacarpal OA was reviewed using PubMed. RESULTS: The observation of work conditions demonstrated unusual forceful and repetitive ulnar flexion of both first fingers. No competing causes of OA could be identified. CONCLUSION: This patient had specific and intense work-related strain of both first carpometacarpal joints. A good temporal relation between work exposure and disease development was demonstrated and it appears likely that the OA was caused by work. However, there is very limited epidemiological evidence relating first carpometacarpal OA to work exposure.  (+info)

The carpometacarpal (CMC) joints are the articulations between the carpal bones of the wrist and the metacarpal bones of the hand. There are five CMC joints in total, with one located at the base of each finger and thumb. The CMC joint of the thumb, also known as the first CMC joint or trapeziometacarpal joint, is the most commonly affected by osteoarthritis. These joints play a crucial role in hand function and movement, allowing for various grips and grasping motions.

In medical terms, the thumb is referred to as "pollex" and it's the first digit of the hand, located laterally to the index finger. It's opposable, meaning it can move opposite to the other fingers, allowing for powerful gripping and precise manipulation. The thumb contains two phalanges bones - the distal and proximal - and is connected to the hand by the carpometacarpal joint, which provides a wide range of motion.

The trapezium bone is a carpal bone located in the wrist, more specifically in the proximal row of carpals. It is situated at the radial side (thumb side) of the wrist and articulates with the Scaphoid bone proximally, the First Metacarpal bone distally, and the Trapezoid and Capitate bones laterally. Its unique shape resembles that of a trapezoid, hence its name. The trapezium plays a crucial role in wrist movements, particularly in thumb abduction and opposition.

The metacarpus is the medical term for the part of the hand located between the carpus (wrist) and the digits (fingers). It consists of five bones, known as the metacarpal bones, which are numbered 1 to 5 from the thumb side to the little finger side. Each metacarpal bone has a base, a shaft, and a head. The bases of the metacarpal bones articulate with the carpal bones to form the wrist joint, while the heads of the metacarpal bones form the knuckles at the back of the hand.

The metacarpus plays an essential role in hand function as it provides stability and support for the movement of the fingers and thumb. Injuries or conditions affecting the metacarpus can significantly impact hand function, causing pain, stiffness, weakness, or deformity.

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.

The metacarpal bones are the long slender bones that make up the middle part of the hand, located between the carpals (wrist bones) and the phalanges (finger bones). There are five metacarpal bones in total, with one for each finger and thumb. Each bone has a base attached to the carpals, a shaft, and a head that connects to the phalanges. The metacarpal bones play a crucial role in hand function, providing stability and support during gripping and manipulation movements.

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.

Osteoarthritis (OA) is a type of joint disease that is characterized by the breakdown and eventual loss of cartilage - the tissue that cushions the ends of bones where they meet in the joints. This breakdown can cause the bones to rub against each other, causing pain, stiffness, and loss of mobility. OA can occur in any joint, but it most commonly affects the hands, knees, hips, and spine. It is often associated with aging and can be caused or worsened by obesity, injury, or overuse.

The medical definition of osteoarthritis is: "a degenerative, non-inflammatory joint disease characterized by the loss of articular cartilage, bone remodeling, and the formation of osteophytes (bone spurs). It is often associated with pain, stiffness, and decreased range of motion in the affected joint."

Carpal bones are the eight small bones that make up the wrist joint in humans and other primates. These bones are arranged in two rows, with four bones in each row. The proximal row includes the scaphoid, lunate, triquetral, and pisiform bones, while the distal row includes the trapezium, trapezoid, capitate, and hamate bones.

The carpal bones play an essential role in the function of the wrist joint by providing stability, support, and mobility. They allow for a wide range of movements, including flexion, extension, radial deviation, ulnar deviation, and circumduction. The complex structure of the carpal bones also helps to absorb shock and distribute forces evenly across the wrist during activities such as gripping or lifting objects.

Injuries to the carpal bones, such as fractures or dislocations, can be painful and may require medical treatment to ensure proper healing and prevent long-term complications. Additionally, degenerative conditions such as arthritis can affect the carpal bones, leading to pain, stiffness, and decreased mobility in the wrist joint.

The carpal joints are a group of articulations in the wrist region of the human body. They consist of eight bones, which are arranged in two rows. The proximal row includes the scaphoid, lunate, triquetral, and pisiform bones, while the distal row includes the trapezium, trapezoid, capitate, and hamate bones.

The carpal joints can be further divided into several smaller joints, including:
1. The midcarpal joint: This joint is located between the proximal and distal rows of carpal bones and allows for flexion, extension, and circumduction movements of the wrist.
2. The radiocarpal joint: This joint is located between the distal end of the radius bone and the scaphoid and lunate bones in the proximal row. It allows for flexion, extension, radial deviation, and ulnar deviation movements of the wrist.
3. The intercarpal joints: These are the joints located between the individual carpal bones within each row. They allow for small gliding movements between the bones.

The carpal joints are surrounded by a fibrous capsule, ligaments, and muscles that provide stability and support to the wrist. The smooth articular cartilage covering the surfaces of the bones allows for smooth movement and reduces friction during articulation.

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.

A dislocation is a condition in which a bone slips out of its normal position in a joint. This can happen as a result of trauma or injury, such as a fall or direct blow to the body. Dislocations can cause pain, swelling, and limited mobility in the affected area. In some cases, a dislocation may also damage surrounding tissues, such as ligaments, tendons, and nerves.

Dislocations are typically treated by reducing the dislocation, which means putting the bone back into its normal position. This is usually done with the help of medication to relieve pain and relaxation techniques to help the person stay still during the reduction. In some cases, surgery may be necessary to repair damaged tissues or if the dislocation cannot be reduced through other methods. After the dislocation has been reduced, the joint may be immobilized with a splint or sling to allow it to heal properly.

It is important to seek medical attention promptly if you suspect that you have a dislocation. If left untreated, a dislocation can lead to further complications, such as joint instability and chronic pain.

Articular ligaments, also known as fibrous ligaments, are bands of dense, fibrous connective tissue that connect and stabilize bones to each other at joints. They help to limit the range of motion of a joint and provide support, preventing excessive movement that could cause injury. Articular ligaments are composed mainly of collagen fibers arranged in a parallel pattern, making them strong and flexible. They have limited blood supply and few nerve endings, which makes them less prone to injury but also slower to heal if damaged. Examples of articular ligaments include the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) in the knee joint, and the medial collateral ligament (MCL) and lateral collateral ligament (LCL) in the elbow joint.

A joint is the location at which two or more bones make contact. They are constructed to allow movement and provide support and stability to the body during motion. Joints can be classified in several ways, including structure, function, and the type of tissue that forms them. The three main types of joints based on structure are fibrous (or fixed), cartilaginous, and synovial (or diarthrosis). Fibrous joints do not have a cavity and have limited movement, while cartilaginous joints allow for some movement and are connected by cartilage. Synovial joints, the most common and most movable type, have a space between the articular surfaces containing synovial fluid, which reduces friction and wear. Examples of synovial joints include hinge, pivot, ball-and-socket, saddle, and condyloid joints.

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).

A hand joint, also known as an articulation, is the location at which two or more bones connect. Specifically, in the context of the hand, there are several types of joints:

1. **Metacarpophalangeal (MCP) Joints:** These are the joints located between the metacarpal bones of the hand and the proximal phalanges of the fingers. The MCP joints allow for flexion, extension, abduction, adduction, and circumduction movements.
2. **Proximal Interphalangeal (PIP) Joints:** These are the joints located between the proximal and middle phalanges of the fingers. The PIP joints allow for flexion, extension, and a limited amount of abduction and adduction movements.
3. **Distal Interphalangeal (DIP) Joints:** These are the joints located between the middle and distal phalanges of the fingers. The DIP joints mainly allow for flexion and extension movements.
4. **Carpometacarpal (CMC) Joints:** These are the joints located between the carpal bones of the wrist and the metacarpal bones of the hand. The CMC joints, particularly the first CMC joint at the base of the thumb, allow for a wide range of movements, including flexion, extension, abduction, adduction, and opposition (the ability to touch the tip of the thumb to each of the other fingers).

These hand joints are supported by various structures such as ligaments, tendons, muscles, and cartilage, which provide stability, enable movement, and absorb shock during daily activities.

I'm happy to help, but I must clarify that "Posters as Topic" is not a medical term or concept. However, if you are referring to "poster" in the context of medical education and conferences, then a medical definition would be:

A 'medical poster' is a graphical presentation of research findings or clinical cases, displayed on a large board or panel, typically during medical conferences, meetings, or educational settings. These posters are designed to provide a concise overview of the study, including background information, methods, results, and conclusions. Medical posters serve as an opportunity for healthcare professionals, researchers, and students to share their work with others in the field, engage in discussions, and receive feedback.

Research personnel, in the context of medical and scientific research, refers to individuals who are involved in the design, conduct, or reporting of research studies. This can include, but is not limited to, principal investigators, co-investigators, research assistants, research coordinators, data managers, biostatisticians, and laboratory technicians. These individuals may have various levels of education, training, and expertise, and their roles and responsibilities will depend on the specific research study and their individual qualifications. It is important for research personnel to adhere to ethical guidelines and regulations in order to ensure the integrity and validity of research findings.

The term "Congresses as Topic" refers to large, formal meetings that are held to discuss and exchange information on a specific topic or field, usually academic or professional in nature. In the context of medical science, a congress is an event where healthcare professionals, researchers, and experts gather to present and discuss the latest research, developments, and innovations in their field. Medical congresses can cover a wide range of topics, including specific diseases, treatments, medical specialties, public health issues, or healthcare policies. These events often include keynote speeches, panel discussions, workshops, poster sessions, and networking opportunities for attendees. Examples of well-known medical congresses are the annual meetings of the American Medical Association, the American Heart Association, and the European Society of Cardiology.

I believe you may have made a typo in your question. The term you're asking about should be "mentor" instead of "mentors." A mentor is not a medical term per se, but I can certainly provide a general definition.

A mentor is a experienced and trusted advisor or guide who provides support, shares knowledge, and helps in the personal and professional development of an individual, often in a specific field or industry. In a medical context, a mentor could be a senior physician or researcher who guides and supports a medical student, resident, or fellow in their learning and career progression.

Medical societies are professional organizations composed of physicians, surgeons, and other healthcare professionals who share a common purpose of promoting medical research, education, and patient care. These societies can focus on specific medical specialties, such as the American Society of Clinical Oncology (ASCO) for cancer specialists or the American College of Surgeons (ACS) for surgeons. They may also address broader issues related to healthcare policy, advocacy, and ethics. Medical societies often provide resources for continuing medical education, publish scientific journals, establish clinical practice guidelines, and offer networking opportunities for members.

Scientific societies are organizations that bring together professionals and researchers in a specific scientific field to promote the advancement of knowledge, research, and application of that science. These societies often engage in activities such as publishing scientific journals, organizing conferences and meetings, providing continuing education and professional development opportunities, and advocating for science policy and funding. Membership may be open to anyone with an interest in the field, or it may be restricted to individuals who meet certain qualifications, such as holding a degree in the relevant scientific discipline. Examples of scientific societies include the American Medical Association (AMA), the American Chemical Society (ACS), and the Royal Society of London.

"Poster" is not a term that has a specific medical definition. It is commonly used in the context of medicine and healthcare to refer to promotional or educational materials displayed on posters, such as those showcased at medical conferences to present research findings. These posters typically include a title, authors, methods, results, and conclusions of a study. However, "poster" does not have a technical or clinical meaning in the field of medicine.
