Rotationplasty is used most often as a function-preserving salvage procedure after resection of sarcomas of the lower extremity; however, it is also used after infection of prosthetic knee joints. Conventional vascular management during rotationplasty is to preserve and coil major vessels, but recently, transection and reanastomosis of the major vessels has been widely performed. However, there...

BACKGROUND Hip and knee prosthetic replacements have proven to be the most appropriate treatment in the joints that do not benefit from medical or arthroscopic interventions; however, infections are the most feared complication. It is recommended that the incidence of infection should not exceed 2%. MATERIAL AND METHODS This was an observational, prospective, longitudinal and observational st...

Late infections with Actinomyces israelii have been described for prosthetic hip joints but not in association with intravenous drug use. We present a case of a 43-year-old intravenous drug user who developed A. israelii infection in connection with a hip prosthesis 11 years after implantation, and we review four previously reported cases of Actinomyces prosthetic joint infections.

Guideline for Prosthetic Joints: Trying to Do the Right Thing In 1997, the American Dental Association (ADA) and the American Academy of Orthopaedic Surgeons (AAOS) published the first advisory statement on antibiotic prophylaxis (AP) for dental patients with prosthetic joints. This advisory statement was updated in 2003 with new information and concluded that AP is not routinely indicated for ...

Septic arthritis of the glenohumoral joint is rare following dental procedures, comprising approximately 3% of all joint infections. Septic arthritis following bacteremia from dental procedures is uncommon and generally occurs in prosthetic joints. Predisposing causes may include immunocompromising diseases such as diabetes, HIV infection, renal failure and intravenous drug abuse. We report a r...

BACKGROUND Persons with unilateral, lower-extremity amputation sometimes develop osteoarthritis in the intact limb. The purpose of this study was to investigate gait mechanics and bone mineral density in unilateral, trans-tibial amputees to test the hypotheses that the intact limb knee and hip will have larger frontal plane net joint moments and bone mineral density than the prosthetic side and...

Prosthetic joint infection (PJI) is a calamitous complication with high morbidity and substantial cost. The reported incidence is low but it is probably underestimated due to the difficulty in diagnosis. PJI has challenged the orthopaedic community for several years and despite all the advances in this field, it is still a real concern with immense impact on patients, and the healthcare system....

A 2-Degrees of freedom powered prosthetic wrist actuator has been proposed that can provide the Abduction/Adduction & Flexion/Extension movements of the human wrist. The basic structure of the actuator is a Ball and Socket joint and the force is transmitted from the DC geared servo motors to the joint through the Bowden cables. The proposed design is capable of providing the required DOF in bot...
