Radiostereometric Analysis (RSA) is a highly accurate and precise method used in medical research and clinical practice to evaluate the motion, migration, or displacement of surgically implanted orthopedic devices such as joint prostheses, screws, or plates. It involves taking simultaneous biplanar X-ray images of the implant from two different angles using a calibration device for size and distance measurements. The resulting stereo images are then digitized and processed to create a 3D model that allows for precise measurement of even small movements of the implant relative to surrounding bone structures. This technique is particularly useful in studying implant stability, wear, and micromotion, which can help optimize surgical techniques and implant designs to improve patient outcomes.

Photogrammetry is not typically considered a medical term, but rather it is a technique used in various fields including engineering, architecture, and geology. However, it has found some applications in the medical field, particularly in orthopedics and wound care. Here's a definition that covers its general use as well as its medical applications:

Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points on an object. It involves the use of photography to accurately measure and map three-dimensional objects or environments. In the medical field, photogrammetry can be used to create 3D models of body parts (such as bones or wounds) by capturing multiple images from different angles and then processing them using specialized software. These 3D models can help healthcare professionals plan treatments, monitor progress, and assess outcomes in a more precise manner.

Tantalum is not a medical term, but a chemical element with the symbol Ta and atomic number 73. It is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. In the field of medicine, tantalum is often used in the production of medical implants such as surgical pins, screws, plates, and stents due to its biocompatibility and resistance to corrosion. For example, tantalum mesh is used in hernia repair and tantalum rods are used in spinal fusion surgery.

Prosthesis failure is a term used to describe a situation where a prosthetic device, such as an artificial joint or limb, has stopped functioning or failed to meet its intended purpose. This can be due to various reasons, including mechanical failure, infection, loosening of the device, or a reaction to the materials used in the prosthesis.

Mechanical failure can occur due to wear and tear, manufacturing defects, or improper use of the prosthetic device. Infection can also lead to prosthesis failure, particularly in cases where the prosthesis is implanted inside the body. The immune system may react to the presence of the foreign material, leading to inflammation and infection.

Loosening of the prosthesis can also cause it to fail over time, as the device becomes less stable and eventually stops working properly. Additionally, some people may have a reaction to the materials used in the prosthesis, leading to tissue damage or other complications that can result in prosthesis failure.

In general, prosthesis failure can lead to decreased mobility, pain, and the need for additional surgeries or treatments to correct the problem. It is important for individuals with prosthetic devices to follow their healthcare provider's instructions carefully to minimize the risk of prosthesis failure and ensure that the device continues to function properly over time.

In the medical field, cementation refers to the process of using a type of dental cement or bonding agent to attach a dental restoration (such as a crown, bridge, or false tooth) to a natural tooth or implant. The cement helps to create a strong and secure attachment, while also helping to seal the restoration and prevent the entry of bacteria and saliva.

Dental cement can be made from various materials, including glass ionomers, resin-modified glass ionomers, zinc phosphate, and polycarboxylate cements. The choice of cement depends on several factors, such as the type of restoration being attached, the location in the mouth, and the patient's individual needs and preferences.

Cementation is an important step in many dental procedures, as it helps to ensure the longevity and success of the restoration. Proper technique and material selection are crucial for achieving a successful cementation that will last for years to come.

A hip prosthesis, also known as a total hip replacement, is a surgical implant designed to replace the damaged or diseased components of the human hip joint. The procedure involves replacing the femoral head (the ball at the top of the thigh bone) and the acetabulum (the socket in the pelvis) with artificial parts, typically made from materials such as metal, ceramic, or plastic.

The goal of a hip prosthesis is to relieve pain, improve joint mobility, and restore function, allowing patients to return to their normal activities and enjoy an improved quality of life. The procedure is most commonly performed in individuals with advanced osteoarthritis, rheumatoid arthritis, or other degenerative conditions that have caused significant damage to the hip joint.

There are several different types of hip prostheses available, each with its own unique design and set of benefits and risks. The choice of prosthesis will depend on a variety of factors, including the patient's age, activity level, overall health, and specific medical needs. In general, however, all hip prostheses are designed to provide a durable, long-lasting solution for patients suffering from debilitating joint pain and stiffness.

I'm sorry for any confusion, but "Polyethylene" is not a medical term. It is a type of synthetic plastic that is commonly used in various industrial and consumer products. Medical definitions typically refer to substances or conditions related to human health, treatment, or disease processes. If you have any questions related to medical terminology or concepts, I'd be happy to help!

Bone cements are medical-grade materials used in orthopedic and trauma surgery to fill gaps between bone surfaces and implants, such as artificial joints or screws. They serve to mechanically stabilize the implant and provide a smooth, load-bearing surface. The two most common types of bone cement are:

1. Polymethylmethacrylate (PMMA) cement: This is a two-component system consisting of powdered PMMA and liquid methyl methacrylate monomer. When mixed together, they form a dough-like consistency that hardens upon exposure to air. PMMA cement has been widely used for decades in joint replacement surgeries, such as hip or knee replacements.
2. Calcium phosphate (CP) cement: This is a two-component system consisting of a powdered CP compound and an aqueous solution. When mixed together, they form a paste that hardens through a chemical reaction at body temperature. CP cement has lower mechanical strength compared to PMMA but demonstrates better biocompatibility, bioactivity, and the ability to resorb over time.

Both types of bone cements have advantages and disadvantages, and their use depends on the specific surgical indication and patient factors.

Prosthesis design is a specialized field in medical device technology that involves creating and developing artificial substitutes to replace a missing body part, such as a limb, tooth, eye, or internal organ. The design process typically includes several stages: assessment of the patient's needs, selection of appropriate materials, creation of a prototype, testing and refinement, and final fabrication and fitting of the prosthesis.

The goal of prosthesis design is to create a device that functions as closely as possible to the natural body part it replaces, while also being comfortable, durable, and aesthetically pleasing for the patient. The design process may involve collaboration between medical professionals, engineers, and designers, and may take into account factors such as the patient's age, lifestyle, occupation, and overall health.

Prosthesis design can be highly complex, particularly for advanced devices such as robotic limbs or implantable organs. These devices often require sophisticated sensors, actuators, and control systems to mimic the natural functions of the body part they replace. As a result, prosthesis design is an active area of research and development in the medical field, with ongoing efforts to improve the functionality, comfort, and affordability of these devices for patients.

Hip arthroplasty, also known as hip replacement surgery, is a medical procedure where the damaged or diseased joint surfaces of the hip are removed and replaced with artificial components. These components typically include a metal or ceramic ball that replaces the head of the femur (thigh bone), and a polyethylene or ceramic socket that replaces the acetabulum (hip socket) in the pelvis.

The goal of hip arthroplasty is to relieve pain, improve joint mobility, and restore function to the hip joint. This procedure is commonly performed in patients with advanced osteoarthritis, rheumatoid arthritis, hip fractures, or other conditions that cause significant damage to the hip joint.

There are several types of hip replacement surgeries, including traditional total hip arthroplasty, partial (hemi) hip arthroplasty, and resurfacing hip arthroplasty. The choice of procedure depends on various factors, such as the patient's age, activity level, overall health, and the extent of joint damage.

After surgery, patients typically require rehabilitation to regain strength, mobility, and function in the affected hip. With proper care and follow-up, most patients can expect significant pain relief and improved quality of life following hip arthroplasty.

Osteoarthritis (OA) of the hip is a degenerative joint disease that affects the articular cartilage and subchondral bone of the hip joint. It is characterized by the progressive loss of cartilage, remodeling of bone, osteophyte formation (bone spurs), cysts, and mild to moderate inflammation. The degenerative process can lead to pain, stiffness, limited range of motion, and crepitus (grating or crackling sound) during movement.

In the hip joint, OA typically affects the femoral head and acetabulum. As the articular cartilage wears away, the underlying bone becomes exposed and can lead to bone-on-bone contact, which is painful. The body responds by attempting to repair the damage through remodeling of the subchondral bone and formation of osteophytes. However, these changes can further limit joint mobility and exacerbate symptoms.

Risk factors for OA of the hip include age, obesity, genetics, previous joint injury or surgery, and repetitive stress on the joint. Treatment options may include pain management (such as NSAIDs, physical therapy, and injections), lifestyle modifications (such as weight loss and exercise), and, in severe cases, surgical intervention (such as hip replacement).

The hip joint, also known as the coxal joint, is a ball-and-socket type synovial joint that connects the femur (thigh bone) to the pelvis. The "ball" is the head of the femur, while the "socket" is the acetabulum, a concave surface on the pelvic bone.

The hip joint is surrounded by a strong fibrous capsule and is reinforced by several ligaments, including the iliofemoral, ischiofemoral, and pubofemoral ligaments. The joint allows for flexion, extension, abduction, adduction, medial and lateral rotation, and circumduction movements, making it one of the most mobile joints in the body.

The hip joint is also supported by various muscles, including the gluteus maximus, gluteus medius, gluteus minimus, iliopsoas, and other hip flexors and extensors. These muscles provide stability and strength to the joint, allowing for weight-bearing activities such as walking, running, and jumping.

The femur is the medical term for the thigh bone, which is the longest and strongest bone in the human body. It connects the hip bone to the knee joint and plays a crucial role in supporting the weight of the body and allowing movement during activities such as walking, running, and jumping. The femur is composed of a rounded head, a long shaft, and two condyles at the lower end that articulate with the tibia and patella to form the knee joint.

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.

Follow-up studies are a type of longitudinal research that involve repeated observations or measurements of the same variables over a period of time, in order to understand their long-term effects or outcomes. In medical context, follow-up studies are often used to evaluate the safety and efficacy of medical treatments, interventions, or procedures.

In a typical follow-up study, a group of individuals (called a cohort) who have received a particular treatment or intervention are identified and then followed over time through periodic assessments or data collection. The data collected may include information on clinical outcomes, adverse events, changes in symptoms or functional status, and other relevant measures.

The results of follow-up studies can provide important insights into the long-term benefits and risks of medical interventions, as well as help to identify factors that may influence treatment effectiveness or patient outcomes. However, it is important to note that follow-up studies can be subject to various biases and limitations, such as loss to follow-up, recall bias, and changes in clinical practice over time, which must be carefully considered when interpreting the results.

I believe there may be some confusion in your question as Polyethylenes are not a medical term, but rather a category of synthetic polymers commonly used in various industrial and medical applications. Here's a brief overview:

Polyethylene (PE) is a type of thermoplastic polymer made from the monomer ethylene. It is a versatile material with numerous applications due to its chemical resistance, durability, and flexibility. There are several types of polyethylenes, including:

1. Low-density polyethylene (LDPE): This type has a lower density and more branching in its molecular structure, which results in less crystallinity. LDPE is known for its flexibility and is often used in packaging films, bags, and containers.
2. High-density polyethylene (HDPE): HDPE has a higher density and less branching, resulting in greater crystallinity. It is more rigid than LDPE and is commonly used in applications such as bottles, pipes, and containers.
3. Linear low-density polyethylene (LLDPE): This type combines the flexibility of LDPE with some of the strength and rigidity of HDPE. LLDPE has fewer branches than LDPE but more than HDPE. It is often used in film applications, such as stretch wrap and agricultural films.
4. Ultra-high molecular weight polyethylene (UHMWPE): UHMWPE has an extremely high molecular weight, resulting in exceptional wear resistance, impact strength, and chemical resistance. It is commonly used in medical applications, such as orthopedic implants and joint replacements, due to its biocompatibility and low friction coefficient.

While polyethylenes are not a medical term per se, they do have significant medical applications, particularly UHMWPE in orthopedic devices.

In the context of medicine, particularly in anatomy and physiology, "rotation" refers to the movement of a body part around its own axis or the long axis of another structure. This type of motion is three-dimensional and can occur in various planes. A common example of rotation is the movement of the forearm bones (radius and ulna) around each other during pronation and supination, which allows the hand to be turned palm up or down. Another example is the rotation of the head during mastication (chewing), where the mandible moves in a circular motion around the temporomandibular joint.

Treatment outcome is a term used to describe the result or effect of medical treatment on a patient's health status. It can be measured in various ways, such as through symptoms improvement, disease remission, reduced disability, improved quality of life, or survival rates. The treatment outcome helps healthcare providers evaluate the effectiveness of a particular treatment plan and make informed decisions about future care. It is also used in clinical research to compare the efficacy of different treatments and improve patient care.

Dura Mater: The tough, outer membrane that covers the brain and spinal cord.

Hydroxyapatite: A naturally occurring mineral form of calcium apatite, also known as dahllite, with the formula Ca5(PO4)3(OH), is the primary mineral component of biological apatites found in bones and teeth.

Therefore, "Durapatite" isn't a recognized medical term, but it seems like it might be a combination of "dura mater" and "hydroxyapatite." If you meant to ask about a material used in medical or dental applications that combines properties of both dura mater and hydroxyapatite, please provide more context.

The tibia, also known as the shin bone, is the larger of the two bones in the lower leg and part of the knee joint. It supports most of the body's weight and is a major insertion point for muscles that flex the foot and bend the leg. The tibia articulates with the femur at the knee joint and with the fibula and talus bone at the ankle joint. Injuries to the tibia, such as fractures, are common in sports and other activities that put stress on the lower leg.

Arthroplasty, replacement, knee is a surgical procedure where the damaged or diseased joint surface of the knee is removed and replaced with an artificial joint or prosthesis. The procedure involves resurfacing the worn-out ends of the femur (thigh bone) and tibia (shin bone) with metal components, and the back of the kneecap with a plastic button. This surgery is usually performed to relieve pain and restore function in patients with severe knee osteoarthritis, rheumatoid arthritis, or traumatic injuries that have damaged the joint beyond repair. The goal of knee replacement surgery is to improve mobility, reduce pain, and enhance the quality of life for the patient.

  • From postoperative radiostereometric measurements it was established that there was no difference in initial stem position between the two approaches. (
  • AIMS: The aim of this prospective cohort study was to evaluate the early migration of the TriFit cementless proximally coated tapered femoral stem using radiostereometric analysis (RSA). (
  • Forty-seven patients (31 boys, 16 girls) with a mean age of 13.2 years (range, 9 to 16) at the time of surgery were available for analysis. (
  • Arandomised controlled trial of cemented versus cementless press-fit condylar total knee replacement: 15-year survival analysis. (
  • After an initial period of rapid penetration in the first year, investigators of a level 1 study using radiostereometric analysis found a significantly lower steady state wear rate during 10-year follow-up among total hip arthroplasties performed with highly crosslinked polyethylene liners compared to conventional polyethylene. (
  • Stable fixation of the IBP humeral component implanted without cement in total elbow replacement: a radiostereometric analysis study of 16 elbows at two-year follow-up. (
  • The thesis is focused on methods enabling 3D analysis of conventional radiographs, based on the registration of digital models into pairs of calibrated X-ray images.The thesis presents a method for reconstruction of complete intact models of long bones suffering displaced diaphyseal fractures from conventional radiographs of individual fragments. (
  • A meta-analysis was conducted to compare CT based versus conventional THA in terms of surgical duration of the procedure, leg length difference, acetabular cup position, and rate of dislocation. (
  • The radiographic analysis revealed stable stems. (
  • Radiostereometric analysis (RSA) studies have shown that the continuous migration of tibial components is predictive of aseptic loosening following total knee arthroplasty (TKA). (
  • Furthermore, radiostereometric analysis has not been used to evaluate the migration of reverse shoulder arthroplasty. (
  • Meta-analyses and literature reviews comparing newer cementless TKA implant designs with cemented implants have found similar or equivalent functional outcomes and survivorship between the 2 implant types 1-5 . (

  • We compared the value of 7.5 Nm external rotation stress in diagnosing tibiofibular syndesmotic injuries of the ankle on lateral radiographs with radiostereometric analysis (RSA) in 10 cadaveric legs. (
  • There will be included a total of 122 patients of which 56 will participate in the radiostereometric analysis. (
  • These patients were assessed by radiostereometric analysis, dual-energy X-ray absorptiometry, and whole blood analysis. (
  • Seventeen studies with 1296 patients were included in the meta-analysis. (
  • The migration is assessed by radiostereometric analysis and the bone mineral density. (
