What is hip arthroplasty?
Best insight from top research papers
Hip arthroplasty, also known as hip replacement, is a surgical procedure aimed at replacing damaged cartilage and bone in the hip joint with implants to restore painless and normal movement . It is commonly performed to address severe osteoarthritis that causes pain and limits joint function, especially when conservative treatments are ineffective . Total hip arthroplasty (THA) is highly successful, providing relief from end-stage degenerative hip conditions like osteoarthritis, osteonecrosis, congenital disorders, and inflammatory arthritis . The procedure involves replacing the femoral component with cobalt-chromium or titanium alloys and the acetabular component with metallic shells and polyethylene liners, fixed using press-fit or bone cement . Preoperative planning and personalized prostheses, facilitated by additive manufacturing techniques, play crucial roles in the success of hip arthroplasty .

What is arthrosis?5 answersArthrosis, also known as osteoarthritis, is a prevalent joint disease causing physical disability and reduced quality of life, especially in older individuals. It is characterized by degeneration of hyaline cartilage and subsequent hardening of subchondral bone, leading to symptoms like pain, muscle imbalance, limited mobility, swelling, joint deformities, and bone damage. Risk factors include aging, trauma, misalignment, and obesity, with inflammation being a key pathophysiological aspect. Treatment involves educating patients on the disease, promoting physical activity, weight management, and pain relief through medications like NSAIDs or opioids, along with options like topical NSAIDs and intra-articular corticosteroids for knee osteoarthritis. Early surgical intervention can improve outcomes, contrary to the belief in delaying arthroplasty.
What are hip implant's parts?5 answersHip implants consist of several essential parts, including a stem, femoral head, acetabular cup, backing cup, ball, and socket assembly. These components are crucial for the functionality and longevity of the implant. The materials used in the design process are biocompatible and robust to ensure the implant's durability. Commonly, the metal components of hip implants are made of cobalt-chromium-molybdenum alloy, stainless steel, or titanium alloy, which are evaluated for their potential to cause adverse effects on the human body. Additionally, some hip implant systems may include a distal stem, proximal body, and fastener, with features like a cavity, threaded exterior surface, and anterior relief for proper positioning and stability within the patient's femoral canal.
How does hip arthroplasty help reduce hip pain in individuals with cerebral palsy?5 answersHip arthroplasty has been shown to effectively reduce hip pain in individuals with cerebral palsy (CP). Studies have highlighted the challenges of managing hip pain in CP patients due to spasticity and communication barriers. Research comparing different perioperative pain management techniques found that lumbar plexus blocks resulted in significantly lower postoperative narcotic consumption, reduced pain scores, and lower heart rates compared to general anesthesia alone or epidural anesthesia. Additionally, long-term outcomes of hip reconstruction procedures, including arthroplasty, have demonstrated stable, painless hips for over a decade in CP patients. Overall, hip arthroplasty in CP patients has shown promising results in alleviating hip pain and improving quality of life.
What is the definition of osteoporosis?4 answersOsteoporosis is a progressive systemic disorder characterized by a loss of bone strength and microarchitecture damage, leading to increased skeletal fragility. It can be diagnosed clinically or by measuring bone mineral density (BMD) using imaging techniques such as dual-energy absorptiometry. Computerized tomography is ideal for evaluating bone integrity, while magnetic resonance imaging is the gold standard for assessing bone marrow. Pathological fractures are associated with high-grade fluorodeoxyglucose (FDG) uptake, while benign fractures show no or low-grade FDG uptake. Osteoporosis affects more than 10 million individuals older than 50 years in the United States and can result in fragility fractures if left untreated. New treatment options, such as abaloparatide and romosozumab, have been approved by the FDA. Weight-bearing and resistance exercises are effective in preventing and treating osteoporosis.
What is arthritis?5 answersArthritis is a joint disorder characterized by inflammation and pain in one or more joints. It is not a single disease, but rather a term that encompasses over 100 medical conditions. The two most common types of arthritis are osteoarthritis and rheumatoid arthritis. Osteoarthritis is a degenerative condition that causes the breakdown of the cartilage in the joints, while rheumatoid arthritis is an autoimmune disease where the immune system attacks the joints. Arthritis can have a significant impact on quality of life, causing disability and even early death in some cases. It is associated with a high economic burden and is expected to increase with the aging population. While there have been advancements in understanding the causes and progression of arthritis, there is still no cure. Current management involves a multidisciplinary approach and pharmacological intervention. Nurses play a crucial role in guiding patients through treatment and optimizing therapy.
What is a total hip arthroplasty?3 answersTotal hip arthroplasty (THA) is a surgical intervention for patients with hip joint disorders. It is an effective treatment for severe degenerative arthritis and various end-stage degenerative conditions of the hip joint. THA relieves pain, restores hip function and mobility, and is one of the most successful and frequently performed surgical procedures. Radiography is used for initial diagnosis and preoperative planning, while computed tomography and magnetic resonance imaging are sometimes used for further evaluation. Intraoperative decisions, such as adjusting length, offset, and implant choices, can contribute to implant stability. Factors like lumbar arthritis and variable pelvic tilt can affect stability postoperatively. Surgeons must consider multiple factors, including bone dimensions, implant longevity, patient expectations, and bone quality, when selecting the optimal solution for THA. The procedure involves replacing the arthritic or necrotic head and neck of the femur with a femoral component made of cobalt-chromium or titanium alloys, and occupying the socket with an acetabular component composed of a shell and liner, usually made of metallic and ultra-high-weight polyethylene materials, respectively. Fixation can be achieved through press-fit, bone cement, or hybrid methods.
