Mechanical considerations in impaction bone grafting. (1/469)

In impaction grafting of contained bone defects after revision joint arthroplasty the graft behaves as a friable aggregate and its resistance to complex forces depends on grading, normal load and compaction. Bone mills in current use produce a distribution of particle sizes more uniform than is desirable for maximising resistance to shear stresses. We have performed experiments in vitro using morsellised allograft bone from the femoral head which have shown that its mechanical properties improve with increasing normal load and with increasing shear strains (strain hardening). The mechanical strength also increases with increasing compaction energy, and with the addition of bioglass particles to make good the deficiency in small and very small fragments. Donor femoral heads may be milled while frozen without affecting the profile of the particle size. Osteoporotic femoral heads provide a similar grading of sizes, although fewer particles are obtained from each specimen. Our findings have implications for current practice and for the future development of materials and techniques.  (+info)

Total joint replacement: implication of cancelled operations for hospital costs and waiting list management. (2/469)

OBJECTIVE: To identify aspects of provision of total joint replacements which could be improved. DESIGN: 10 month prospective study of hospital admissions and hospital costs for patients whose total joint replacement was cancelled. SETTING: Information and Waiting List Unit, Musgrave Park Regional Orthopaedic Service, Belfast. PATIENTS: 284 consecutive patients called for admission for total joint replacement. MAIN MEASURES: Costs of cancellation of operation after admission in terms of hotel and opportunity costs. RESULTS: 28(10%) planned operations were cancelled, 27 of which were avoidable cancellations. Five replacement patients were substituted on the theatre list, leaving 22(8%) of 232 operating theatre opportunities unused. Patients seen at assessment clinics within two months before admission had a significantly higher operation rate than those admitted from a routine waiting list (224/232(97%) v 32/52(62%), x2 = 58.6, df = 1; p < 0.005). Mean duration of hospital stay in 28 patients with cancelled operations was 1.92 days. Operating theatre opportunity costs were 73% of the total costs of cancelled total joint replacements. CONCLUSION: Patients on long waiting lists for surgery should be reassessed before admission to avoid wasting theatre opportunities, whose cost is the largest component of the total costs of cancelled operations.  (+info)

Extensible endoprostheses of the humerus after resection of bone tumours. (3/469)

We carried out extensible endoprosthetic replacement of the proximal or total humerus in 18 children aged between six and 12 years, after resection of primary bone tumours mainly for osteosarcoma and Ewing's sarcoma. In 11 patients we performed 44 lengthening procedures, with an average of two per child annually and a mean total extension of 29.9 mm per patient. We were able to achieve lengthening of the operated limb with few complications and a mean functional rating of 79.3% according to the Enneking system. Progressive lengthening of these prostheses does not adversely affect the overall function of the arm, and superior subluxation of the head of the prosthesis has not been a problem.  (+info)

Screening for Staphylococcus epidermidis markers discriminating between skin-flora strains and those responsible for infections of joint prostheses. (4/469)

Fifty-four Staphylococcus epidermidis strains responsible for infections of joint prostheses and 23 strains isolated from skin flora were studied for markers of virulence, to discriminate invasive strains from normal flora. They were screened for binding to polystyrene and matrix proteins and for the presence of staphylococcal genes involved in adhesion. The ica operon involved in biofilm formation was the only marker discriminating between these 2 categories of strains.  (+info)

Silicone lymphadenopathy mimicking a lymphoma in a patient with a metatarsophalangeal joint prosthesis. (5/469)

With lymph node enlargement, the possibility of a malignant process such as metastatic carcinoma or lymphoma needs to be excluded. This report describes a 47 year old woman with inguinal lymph node enlargement initially suspicious for lymphoma. Fine needle aspiration findings favoured reactive hyperplasia, but a malignant process could not be excluded. The final histological diagnosis was a foreign body granulomatous inflammatory response as a result of regionally disseminated silicone particles from an over looked metatarsophalangeal joint prosthesis. Because of the large number of joint prostheses world wide, it should be kept in mind that migration of wear particles can create granulomatous inflammation and node enlargement.  (+info)

The management of local complications of total hip replacement by the McKee-Farrar technique. (6/469)

One thousand and forty-two McKee-Farrar prostheses of the present design inserted in Norwich from January 1965 to December 1972 have been reviewed retrospectively to determine the incidence of complications needing revision. Of prostheses implanted for more than two years, 6-6 per cent needed revision for loosening (cup 3-5 per cent; stem 2-2 per cent; both components 0-9 per cent). Of the total number, 2-3 per cent became infected and 1-9 per cent dislocated. Most dislocations needed only a single closed reduction but 0-8 per cent were revised. The outcome of revision operations was also assessed. Of revisions for loosening, 40 per cent needed no further operation but 23 per cent required excision; pelvic fracture or bone destruction around the components made success unlikely. Revisions for dislocation were disappointing. Of all revisions 17 per cent became infected. Excision arthroplasty is better than a series of failed revisions in an elderly patient.  (+info)

The Walldius hinge arthroplasty. (7/469)

Eighty-three Walldius arthroplasties, performed by one surgeon as salvage operation on the knee joint between 1966 and 1972, were independently reviewed. The fifty-seven living patients with sixty-seven arthroplasties were interviewed and examined and the clinical records of the deceased patients were inspected. Sixty-seven arthroplasties (81 per cent) were successful and sixteen failed (19 per cent). Acrylic cement was used to secure the prosthesis on eight occasions only. There were two primary infections (2-4 per cent) and two delayed (2-4 per cent). Major loosening occurred in three arthroplasties (3-6 per cent). Minor loosening was compatible with a good result. Arthrodesis was successful on the two occasions on which it became necessary to remove the implant. There were no disasters. On the basis of these results it is considered that the Walldius arthroplasty can justifiably be offered as an alternative to primary arthrodesis of the knee.  (+info)

Link arthroplasty of the metacarpo-phalangeal joints. A preliminary report of a new method. (8/469)

Link arthroplasty is a system of joint replacement in which the joint is left almost intact with no great removal of bone. It is based on a two-piece self-locking hinge slotted into the metacarpal head and phalangeal shaft. The operation is simple and no special instruments are needed. The preliminary follow-up of fifty-four metacarpo-phalangeal joint replacements showed thirty-five good and sixteen fair results.  (+info)

There are several types of prosthesis-related infections, including:

1. Bacterial infections: These are the most common type of prosthesis-related infection and can occur around any type of implanted device. They are caused by bacteria that enter the body through a surgical incision or other opening.
2. Fungal infections: These types of infections are less common and typically occur in individuals who have a weakened immune system or who have been taking antibiotics for another infection.
3. Viral infections: These infections can occur around implanted devices, such as pacemakers, and are caused by viruses that enter the body through a surgical incision or other opening.
4. Parasitic infections: These types of infections are rare and occur when parasites, such as tapeworms, infect the implanted device or the surrounding tissue.

Prosthesis-related infections can cause a range of symptoms, including pain, swelling, redness, warmth, and fever. In severe cases, these infections can lead to sepsis, a potentially life-threatening condition that occurs when bacteria or other microorganisms enter the bloodstream.

Prosthesis-related infections are typically diagnosed through a combination of physical examination, imaging tests such as X-rays or CT scans, and laboratory tests to identify the type of microorganism causing the infection. Treatment typically involves antibiotics or other antimicrobial agents to eliminate the infection, and may also involve surgical removal of the infected implant.

Prevention is key in avoiding prosthesis-related infections. This includes proper wound care after surgery, keeping the surgical site clean and dry, and taking antibiotics as directed by your healthcare provider to prevent infection. Additionally, it is important to follow your healthcare provider's instructions for caring for your prosthesis, such as regularly cleaning and disinfecting the device and avoiding certain activities that may put excessive stress on the implant.

Overall, while prosthesis-related infections can be serious, prompt diagnosis and appropriate treatment can help to effectively manage these complications and prevent long-term damage or loss of function. It is important to work closely with your healthcare provider to monitor for signs of infection and take steps to prevent and manage any potential complications associated with your prosthesis.

It is important to identify and address prosthesis failure early to prevent further complications and restore the functionality of the device. This may involve repairing or replacing the device, modifying the design, or changing the materials used in its construction. In some cases, surgical intervention may be necessary to correct issues related to the implantation of the prosthetic device.

Prosthesis failure can occur in various types of prosthetic devices, including joint replacements, dental implants, and orthotic devices. The causes of prosthesis failure can range from manufacturing defects to user error or improper maintenance. It is essential to have a comprehensive understanding of the factors contributing to prosthesis failure to develop effective solutions and improve patient outcomes.

In conclusion, prosthesis failure is a common issue that can significantly impact the quality of life of individuals who rely on prosthetic devices. Early identification and addressing of prosthesis failure are crucial to prevent further complications and restore functionality. A comprehensive understanding of the causes of prosthesis failure is necessary to develop effective solutions and improve patient outcomes.

1. Osteoarthritis: A degenerative condition that causes the breakdown of cartilage in the joints, leading to pain, stiffness, and loss of mobility.
2. Rheumatoid arthritis: An autoimmune disease that causes inflammation in the joints, leading to pain, swelling, and deformity.
3. Gout: A condition caused by the buildup of uric acid in the joints, leading to sudden and severe attacks of pain, inflammation, and swelling.
4. Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion the joints and reduce friction between tendons and bones.
5. Tendinitis: Inflammation of the tendons, which connect muscles to bones.
6. Synovitis: Inflammation of the synovial membrane, a thin lining that covers the joints and lubricates them with fluid.
7. Periarthritis: Inflammation of the tissues around the joints, such as the synovial membrane, tendons, and ligaments.
8. Spondyloarthritis: A group of conditions that affect the spine and sacroiliac joints, leading to inflammation and pain in these areas.
9. Juvenile idiopathic arthritis: A condition that affects children and causes inflammation and pain in the joints.
10. Systemic lupus erythematosus: An autoimmune disease that can affect many parts of the body, including the joints.

These are just a few examples of the many types of joint diseases that exist. Each type has its own unique symptoms and causes, and they can be caused by a variety of factors such as genetics, injury, infection, or age-related wear and tear. Treatment options for joint diseases can range from medication and physical therapy to surgery, depending on the severity of the condition and its underlying cause.

There are several types of joint instability, including:

1. Ligamentous laxity: A condition where the ligaments surrounding a joint become stretched or torn, leading to instability.
2. Capsular laxity: A condition where the capsule, a thin layer of connective tissue that surrounds a joint, becomes stretched or torn, leading to instability.
3. Muscular imbalance: A condition where the muscles surrounding a joint are either too weak or too strong, leading to instability.
4. Osteochondral defects: A condition where there is damage to the cartilage and bone within a joint, leading to instability.
5. Post-traumatic instability: A condition that develops after a traumatic injury to a joint, such as a dislocation or fracture.

Joint instability can be caused by various factors, including:

1. Trauma: A sudden and forceful injury to a joint, such as a fall or a blow.
2. Overuse: Repeated stress on a joint, such as from repetitive motion or sports activities.
3. Genetics: Some people may be born with joint instability due to inherited genetic factors.
4. Aging: As we age, our joints can become less stable due to wear and tear on the cartilage and other tissues.
5. Disease: Certain diseases, such as rheumatoid arthritis or osteoarthritis, can cause joint instability.

Symptoms of joint instability may include:

1. Pain: A sharp, aching pain in the affected joint, especially with movement.
2. Stiffness: Limited range of motion and stiffness in the affected joint.
3. Swelling: Swelling and inflammation in the affected joint.
4. Instability: A feeling of looseness or instability in the affected joint.
5. Crepitus: Grinding or crunching sensations in the affected joint.

Treatment for joint instability depends on the underlying cause and may include:

1. Rest and ice: Resting the affected joint and applying ice to reduce pain and swelling.
2. Physical therapy: Strengthening the surrounding muscles to support the joint and improve stability.
3. Bracing: Using a brace or splint to provide support and stability to the affected joint.
4. Medications: Anti-inflammatory medications, such as ibuprofen or naproxen, to reduce pain and inflammation.
5. Surgery: In severe cases, surgery may be necessary to repair or reconstruct the damaged tissues and improve joint stability.

The exact cause of osteoarthritis is not known, but it is thought to be due to a combination of factors such as genetics, wear and tear on joints over time, and injuries or trauma to the joint. Osteoarthritis can affect any joint in the body, but it most commonly affects the hands, knees, hips, and spine.

The symptoms of osteoarthritis can vary depending on the severity of the condition and which joint is affected. Common symptoms include:

* Pain or tenderness in the joint
* Stiffness, especially after periods of rest or inactivity
* Limited mobility or loss of flexibility
* Grating or crackling sensations when the joint is moved
* Swelling or redness in the affected joint
* Muscle weakness or wasting

There is no cure for osteoarthritis, but there are several treatment options available to manage the symptoms and slow the progression of the disease. These include:

* Pain relief medications such as acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs)
* Physical therapy to improve mobility and strength
* Lifestyle modifications such as weight loss, regular exercise, and avoiding activities that exacerbate the condition
* Bracing or orthotics to support the affected joint
* Corticosteroid injections or hyaluronic acid injections to reduce inflammation and improve joint function
* Joint replacement surgery in severe cases where other treatments have failed.

Early diagnosis and treatment of osteoarthritis can help manage symptoms, slow the progression of the disease, and improve quality of life for individuals with this condition.

  • Joint replacements are commonly coated with bioceramic materials to reduce wear and inflammatory response. (
  • Thus, we conclude that the internal TMJ prostheses used in this studywere satisfactory, promoting mandibular movements mostly in normal ranges, withsignificant pain reduction. (
  • However, when the ranges of motion (ROMs) of the ankle and subtalar joints (talocalcaneal and talocalcaneonavicular) are taken together, the complex functions as a universal joint. (
  • New implant materials and improved surgical techniques for joint replacement have been developed over the past three decades. (
  • The organism of Whipple disease, Mycoplasma species, and Ureaplasma species infrequently involve septic joints. (
  • Current replacement joint surfaces can wear away after 15 to 20 years. (
  • The ankle joint is a hinged synovial joint with primarily up-and-down movement (plantarflexion and dorsiflexion). (
  • The knee joint is surrounded by a thin lining called the synovial membrane. (
  • For more information about the relevant anatomy, see Ankle Joint Anatomy . (
  • The affected joint is resurfaced with a prosthesis, which is a new joint made of metal and plastic components. (
  • What Is a Joint Replacement Made of? (
  • Preparation and submission of questionnaires to the main companies involved in the prosthesis market. (
  • [ 3 ] Using the extensor surface of the joint for needle insertion, while keeping the joint in minimal flexion, minimizes the risk of such injuries. (
  • Any joint in the body may be affected by the disease, but it is particularly common in the knee. (
  • The recommendations cover units, test specimen, test conditions and test methods for evaluating the characteristics of hip joint prostheses by means of simulators. (
  • We found that joint intervention, which includes both coaching using motivational interviewing and financial incentives, substantially improves the number of steps that total knee replacement recipients did daily and the total minutes of physical activity,' Dr. Losina said. (
  • Theoretically, any joint in the body can be replaced, but most joint replacement surgeries involve the knee and hip . (
  • Our comprehensive total joint replacement program includes the involvement of people who care about the patient-family and friends, the surgeon, occupational and physical therapists, nurses, patient care technicians, case managers, a program coordinator, and many other team members. (
  • It is symmetrical, meaning that it usually affects the same joint on both sides of the body. (
