Finger joint synovitis in rheumatoid arthritis: quantitative assessment by magnetic resonance imaging. (1/175)

OBJECTIVE: To assess quantitatively, by magnetic resonance imaging (MRI), the synovial membrane volume in second to fifth metacarpophalangeal (MCP) joints in patients with rheumatoid arthritis and healthy controls, and to compare the synovial membrane volumes with a more easily obtained semi-quantitative score for hypertrophic synovial membrane. PATIENTS AND METHODS: MCP joints of the dominant hand of 37 patients and five controls were examined clinically and by MRI. Laboratory assessments were performed. RESULTS: Median synovial membrane volumes were considerably larger in clinically active rheumatoid arthritis (RA) joints (e.g. 0.97 ml in the second MCP joint) than in clinically inactive joints (0.54 ml) and control joints (0.04 ml). Nevertheless, group distributions overlapped and marked volume differences were found within clinically uniform groups. The semi-quantitative score was highly correlated with the synovial volumes (Spearman rho = 0.79; P < 0.00001). Synovial membrane volumes were poorly related to the presence of rheumatoid factor and to laboratory markers of inflammation. CONCLUSION: These findings suggest that synovial membrane volumes, as determined by MRI, in finger joints are related to clinical signs of synovitis, but also that the volumes may vary more than what can be accounted for by the clinical appearances. A semi-quantitative score may be sufficient for more routine purposes.  (+info)

A preliminary study of ultrasound aspiration of bone erosion in early rheumatoid arthritis. (2/175)

OBJECTIVE: To develop a new technique to assess the primary lesion in early rheumatoid arthritis (RA). METHODS: Ten patients with early RA and radiographically or MRI confirmed erosions had a needle introduced into the base of the erosion under sonographic guidance. Material was then aspirated from this site. RESULTS: The procedure was well tolerated with no complications. Small samples of necrotic bone and tissue were obtained in five out of 10 cases. In one case, a distinctive population of pleomorphic CD34 + cells with characteristics of bone marrow progenitors was isolated. Tissue invading bone with a characteristic appearance of pannus was not seen. CONCLUSION: A new method of sampling the earliest lesion in RA is described. The findings raise questions about the nature of bone damage in early RA.  (+info)

Sensory processing in Parkinson's and Huntington's disease: investigations with 3D H(2)(15)O-PET. (3/175)

There is conjoining experimental and clinical evidence supporting a fundamental role of the basal ganglia as a sensory analyser engaged in central somatosensory control. This study was aimed at investigating the functional anatomy of sensory processing in two clinical conditions characterized by basal ganglia dysfunction, i.e. Parkinson's and Huntington's disease. Based on previously recorded data of somatosensory evoked potentials, we expected deficient sensory-evoked activation in cortical areas that receive modulatory somatosensory input via the basal ganglia. Eight Parkinson's disease patients, eight Huntington's disease patients and eight healthy controls underwent repetitive H(2)(15)O-PET activation scans during two experimental conditions in random order: (i) continuous unilateral high-frequency vibratory stimulation applied to the immobilized metacarpal joint of the index finger and (ii) rest (no vibratory stimulus). In the control cohort, the activation pattern was lateralized to the side opposite to stimulus presentation, including cortical [primary sensory cortex (S1); secondary sensory cortex (S2)] and subcortical (globus pallidus, ventrolateral thalamus) regional cerebral blood flow (rCBF) increases (P < 0.001). Between-group comparisons (P < 0.01) of vibration-induced rCBF changes between patients and controls revealed differences in central sensory processing: (i) in Parkinson's disease, decreased activation of contralateral sensorimotor (S1/M1) and lateral premotor cortex, contralateral S2, contralateral posterior cingulate, bilateral prefrontal cortex (Brodmann area 10) and contralateral basal ganglia; (ii) in Huntington's disease, decreased activation of contralateral S2, parietal areas 39 and 40, and lingual gyrus, bilateral prefrontal cortex (Brodmann areas 8, 9, 10 and 44), S1 (trend only) and contralateral basal ganglia; (iii) in both clinical conditions relative enhanced activation of ipsilateral sensory cortical areas, notably caudal S1, S2 and insular cortex. Our data show that Parkinson's disease and Huntington's disease, beyond well-established deficits in central motor control, are characterized by abnormal cortical and subcortical activation on passive sensory stimulation. Furthermore, the finding that activation increases in ipsilateral sensory cortical areas may be interpreted as an indication of either altered central focusing and gating of sensory impulses, or enhanced compensatory recruitment of associative sensory areas in the presence of basal ganglia dysfunction. Altered sensory processing is thought to contribute to pertinent motor deficits in both conditions.  (+info)

Fibrocartilage in the extensor tendons of the human metacarpophalangeal joints. (4/175)

The extensor tendons of the fingers cross both the metacarpophalangeal (MCP) and interphalangeal joints. Previous studies have shown that where the extensor tendons replace the capsule of the proximal interphalangeal (PIP) joint, they contain a sesamoid fibrocartilage that articulates with the proximal phalanx during flexion. The fibrocartilage labels immunohistochemically for a variety of glycosaminoglycans and collagens. In the current study, we investigate the molecular composition of the extensor tendons at the level of the MCP joints. This is of particular interest because the tendon has a greater moment arm at this location (and might thus be subject to greater compression), but is separated from the joint cavity by the capsule and peritendinous tissue. Six hands were removed from elderly cadavers (39-85 years of age) and the MCP joints were fixed in 90% methanol. The extensor tendons were dissected from all fingers, cryosectioned, and immunolabelled with a panel of monoclonal and polyclonal antibodies for types I, II, III, and VI collagens, chondroitin 4 and 6 sulphates, dermatan, and keratan sulphate and aggrecan. Antibody binding was detected with the Vectastain ABC 'Elite' avidin/biotin/peroxidase kit. The extensor tendons in all the fingers had a metachromatic sesamoid fibrocartilage on their deep surface which immunolabelled for types I, III, and VI collagens, and for all glycosaminoglycans and aggrecan. Labelling for type II collagen was also seen in some fibrocartilages and was a constant feature of all index fingers. This probably relates to the greater use of that digit and the higher loads to which its tendons are subject. Chondroitin 6 sulphate and type II collagen are the most consistent markers of the fibrocartilage phenotype and most of the chondroitin 6 sulphate is probably associated with aggrecan. It is concluded that the labelling profile of the tendon fibrocartilage in the different fingers at the MCP joints is broadly similar to that at the PIP joints. Thus, the potentially greater level of compression on the extensor tendons may be counterbalanced by the lack of fusion of the tendon with the joint capsule. It is suggested that the maintenance of a similar level of fibrocartilage differentiation at two different points along the length of the extensor tendon ensures that the tensile strength is the same in the two regions and that no weak link is present.  (+info)

Synovitis of small joints: sonographic guided diagnostic and therapeutic approach. (5/175)

OBJECTIVE: The aim of this pictorial essay is to describe the sonographic guided approach to investigation and local injection therapy of a small joint in a patient with psoriatic arthritis (PA). METHODS: Sonographic pictures are obtained using a high frequency ultrasonography apparatus equipped with a 13-MHz transducer. RESULTS: Ultrasonography allows a careful morphostructural assessment of soft tissue involvement in PA patients. Sonographic findings include joint cavity widening, capsular thickening, synovial proliferation, synovial fluid changes, tendon sheath widening. Ultrasound guided placement of the needle within the joint and injection of corticosteroid under sonographic control can be easily performed. CONCLUSIONS: High frequency ultrasonography is a quick and safe procedure that allows a useful diagnostic and therapeutic approach in patients with arthritis of small joints.  (+info)

Evaluation of pannus and vascularization of the metacarpophalangeal and proximal interphalangeal joints in rheumatoid arthritis by high-resolution ultrasound (multidimensional linear array). (6/175)

OBJECTIVE: To evaluate the extent of intraarticular vascularization and pannus formation in metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints of patients with rheumatoid arthritis (RA) by high-resolution ultrasound (US). METHODS: A newly developed, high-resolution multidimensional linear array US was utilized to obtain longitudinal and transverse scans of joints with active RA (n = 21), moderately active RA (n = 39), or inactive RA (n = 93), and of joints from healthy controls (n = 120). RESULTS: Healthy joints had no detectable pannus, whereas pannus could be detected in 52% of the joints with active RA, 82% of the joints with moderately active RA, and 67% of the joints with inactive RA. There was a significant difference in vascularization in the joints of all subgroups of RA patients and those of healthy subjects (P < 0.001). Moreover, vascularization differed significantly among the RA subgroups: inactive versus moderately active RA (P < 0.02) and inactive versus active RA (P < 0.05). Both pannus and vascularization appeared to be localized preferentially on the radial side of the joints. CONCLUSION: Evaluation of pannus and the extent of vascularization within the joints of patients with RA by high-resolution US might be helpful in the assessment of disease activity, and thus influence therapeutic strategies.  (+info)

Trapeziectomy for basal thumb joint osteoarthritis: 3- to 19-year follow-up. (7/175)

A consecutive series of 40 trapeziectomies in 30 patients with basal thumb joint osteoarthritis was reviewed. Sixteen thumbs had pan-trapezial and 24 thumbs trapeziometacarpal osteoarthritis. Simple excision without soft tissue interposition was performed by the same surgeon using an identical surgical technique. Twenty-eight patients were female (mean age 57 years) with a mean follow-up of 11 (3-19) years. Twenty-eight patients were satisfied with their operation, with 26 thumbs being pain free. Thumb pinch strength was improved by 40% compared to preoperative values, but still remained 22% weaker than the non-operated side.  (+info)

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.

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.

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 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.

Collateral ligaments are a pair of strong bands of tissue located on the lateral (outer) and medial (inner) sides of joints, particularly in the knee and ankle. They help to stabilize and limit the side-to-side movement of the joint by preventing excessive abnormal displacement or dislocation.

In the knee, there are two collateral ligaments:

1. Medial Collateral Ligament (MCL): It runs along the inner side of the knee and connects the femur (thigh bone) to the tibia (shin bone). The MCL helps to prevent excessive inward movement or valgus stress of the knee joint.
2. Lateral Collateral Ligament (LCL): It is located on the outer side of the knee and connects the femur to the fibula (the smaller bone in the lower leg). The LCL helps to prevent excessive outward movement or varus stress of the knee joint.

In the ankle, there are also two collateral ligaments:

1. Deltoid Ligament: It is a group of ligaments located on the inner side of the ankle and connects the tibia to the talus (ankle bone) and calcaneus (heel bone). The deltoid ligament helps to prevent excessive inward movement or eversion of the ankle joint.
2. Anterior Talofibular Ligament: It is a ligament located on the outer side of the ankle, connecting the talus to the fibula. The anterior talofibular ligament helps to prevent excessive outward movement or inversion of the ankle joint.

Synovial chondromatosis is a rare condition that affects the synovial membrane, which is the lining of joints, bursae (fluid-filled sacs that cushion bones), and tendon sheaths. In this condition, nodules made up of cartilage form in the synovial membrane. These nodules can detach from the synovial membrane and float freely in the synovial fluid, which lubricates the joint. If they become numerous, they can cause joint pain, stiffness, and decreased range of motion. In some cases, the loose bodies may also cause locking or catching sensations in the joint. Surgery is typically required to remove the cartilaginous nodules and relieve symptoms. If left untreated, synovial chondromatosis can lead to osteoarthritis and other joint problems.

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.

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.

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.

Finger injuries refer to any damage or trauma caused to the fingers, which can include cuts, bruises, dislocations, fractures, and sprains. These injuries can occur due to various reasons such as accidents, sports activities, falls, or direct blows to the finger. Symptoms of finger injuries may include pain, swelling, stiffness, deformity, numbness, or inability to move the finger. The treatment for finger injuries varies depending on the type and severity of the injury, but may include rest, immobilization, ice, compression, elevation, physical therapy, medication, or surgery. It is essential to seek medical attention promptly for proper diagnosis and treatment of finger injuries to prevent further complications and ensure optimal recovery.

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).

Arthroplasty, replacement, finger is a surgical procedure in which a damaged or arthritic joint in a finger is replaced with an artificial component, typically made from materials such as metal, plastic, or ceramic. This procedure is usually considered when non-surgical treatments have failed to provide adequate pain relief and improve joint function.

The goal of finger joint replacement surgery is to alleviate pain, restore motion, and enhance the overall functionality of the affected finger. During the procedure, the surgeon removes the damaged surfaces of the joint and inserts the artificial component, which is designed to replicate the natural movement of the joint. After the surgery, patients typically undergo a period of rehabilitation to regain strength, range of motion, and dexterity in the affected finger.

Finger joint replacement surgery can be performed on various joints in the fingers, including the distal interphalangeal (DIP) joint, located at the tip of the finger, and the proximal interphalangeal (PIP) joint, situated between the middle and last bone segments. The choice of surgical approach depends on several factors, such as the severity of joint damage, the patient's age, overall health, and occupational demands.

It is essential to consult with a medical professional for a proper diagnosis and treatment plan tailored to individual needs and circumstances.

Rheumatoid arthritis (RA) is a systemic autoimmune disease that primarily affects the joints. It is characterized by persistent inflammation, synovial hyperplasia, and subsequent damage to the articular cartilage and bone. The immune system mistakenly attacks the body's own tissues, specifically targeting the synovial membrane lining the joint capsule. This results in swelling, pain, warmth, and stiffness in affected joints, often most severely in the hands and feet.

RA can also have extra-articular manifestations, affecting other organs such as the lungs, heart, skin, eyes, and blood vessels. The exact cause of RA remains unknown, but it is believed to involve a complex interplay between genetic susceptibility and environmental triggers. Early diagnosis and treatment are crucial in managing rheumatoid arthritis to prevent joint damage, disability, and systemic complications.

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.

In medical terms, fingers are not specifically defined as they are common anatomical structures. However, I can provide you with a general anatomy definition:

Fingers are the terminal parts of the upper limb in primates, including humans, consisting of four digits (thumb, index, middle, and ring fingers) and one opposable thumb. They contain bones called phalanges, connected by joints that allow for movement and flexibility. Each finger has a nail, nerve endings for sensation, and blood vessels to supply nutrients and oxygen. Fingers are crucial for various activities such as grasping, manipulating objects, and tactile exploration of the environment.

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."

Joint instability is a condition characterized by the loss of normal joint function and increased risk of joint injury due to impaired integrity of the supporting structures, such as ligaments, muscles, or cartilage. This can result in excessive movement or laxity within the joint, leading to decreased stability and increased susceptibility to dislocations or subluxations. Joint instability may cause pain, swelling, and limited range of motion, and it can significantly impact a person's mobility and quality of life. It is often caused by trauma, degenerative conditions, or congenital abnormalities and may require medical intervention, such as physical therapy, bracing, or surgery, to restore joint stability.

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. It provides a cushion between bones and allows for smooth movement by reducing friction. Articular cartilage also absorbs shock and distributes loads evenly across the joint, protecting the bones from damage. It is avascular, meaning it does not have its own blood supply, and relies on the surrounding synovial fluid for nutrients. Over time, articular cartilage can wear down or become damaged due to injury or disease, leading to conditions such as osteoarthritis.

I'm sorry for any confusion, but "horses" is not a medical term. It is the common name given to the species *Equus ferus caballus*, which are large domesticated mammals used for transportation, work, and recreation. If you have any questions about horses or a related topic that you would like a medical perspective on, please let me know and I'd be happy to help!

Articular Range of Motion (AROM) is a term used in physiotherapy and orthopedics to describe the amount of movement available in a joint, measured in degrees of a circle. It refers to the range through which synovial joints can actively move without causing pain or injury. AROM is assessed by measuring the degree of motion achieved by active muscle contraction, as opposed to passive range of motion (PROM), where the movement is generated by an external force.

Assessment of AROM is important in evaluating a patient's functional ability and progress, planning treatment interventions, and determining return to normal activities or sports participation. It is also used to identify any restrictions in joint mobility that may be due to injury, disease, or surgery, and to monitor the effectiveness of rehabilitation programs.

A finger phalanx is the medical term for the bones that make up each finger, excluding the thumb. The fingers typically consist of three phalanges, named proximally (nearest to the hand), middle, and distally (farthest from the hand). Each phalanx has a base, body, and head. The base articulates with the preceding bone, while the head articulates with the following bone to form a joint. The thumb, having only two phalanges, consists of a proximal and distal phalanx.

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.

Biomechanics is the application of mechanical laws to living structures and systems, particularly in the field of medicine and healthcare. A biomechanical phenomenon refers to a observable event or occurrence that involves the interaction of biological tissues or systems with mechanical forces. These phenomena can be studied at various levels, from the molecular and cellular level to the tissue, organ, and whole-body level.

Examples of biomechanical phenomena include:

1. The way that bones and muscles work together to produce movement (known as joint kinematics).
2. The mechanical behavior of biological tissues such as bone, cartilage, tendons, and ligaments under various loads and stresses.
3. The response of cells and tissues to mechanical stimuli, such as the way that bone tissue adapts to changes in loading conditions (known as Wolff's law).
4. The biomechanics of injury and disease processes, such as the mechanisms of joint injury or the development of osteoarthritis.
5. The use of mechanical devices and interventions to treat medical conditions, such as orthopedic implants or assistive devices for mobility impairments.

Understanding biomechanical phenomena is essential for developing effective treatments and prevention strategies for a wide range of medical conditions, from musculoskeletal injuries to neurological disorders.

A toe joint, also known as a metatarsophalangeal (MTP) joint, is the articulation between the bones in the foot (metatarsals) and the bones in the toes (phalanges). There are five MTP joints in each foot, one for each toe except for the big toe, which has its own separate joint called the first metatarsophalangeal joint.

The MTP joints allow for movement and flexibility of the toes, enabling activities such as walking, running, and standing. Problems with these joints can lead to pain, stiffness, and difficulty moving, making it important to maintain their health and mobility through proper foot care and exercise.

In the context of medicine and healthcare, "movement" refers to the act or process of changing physical location or position. It involves the contraction and relaxation of muscles, which allows for the joints to move and the body to be in motion. Movement can also refer to the ability of a patient to move a specific body part or limb, which is assessed during physical examinations. Additionally, "movement" can describe the progression or spread of a disease within the body.

Dupuytren contracture is a medical condition that affects the hand, specifically the fascia, which is a layer of connective tissue beneath the skin of the palm. In this condition, the fascia thickens and shortens, causing one or more fingers to bend towards the palm and making it difficult to straighten them. The ring finger and little finger are most commonly affected, but the middle finger and thumb can also be involved.

The exact cause of Dupuytren contracture is not known, but it is more common in men than women and tends to run in families. It is also associated with certain medical conditions such as diabetes, seizures, and alcoholism. There is no cure for Dupuytren contracture, but treatments such as surgery or needle aponeurotomy can help relieve symptoms and improve hand function.

The metatarsophalangeal (MTP) joint is the joint in the foot where the metatarsal bones of the foot (the long bones behind the toes) connect with the proximal phalanges of the toes. It's a synovial joint, which means it's surrounded by a capsule containing synovial fluid to allow for smooth movement. The MTP joint is responsible for allowing the flexion and extension movements of the toes, and is important for maintaining balance and pushing off during walking and running. Issues with the MTP joint can lead to conditions such as hallux valgus (bunions) or hammertoe.
