BACKGROUND Orthopedic Implant removal is one of the commonly performed elective orthopedic surgeries. Implants are generally removed after the purpose of keeping implant is solved by healing of the fracture, but there is no consensus whether routine implant removal should be a policy for all fractures that were fixed. OBJECTIVE This study aims to analyze the epidemiology and outcome of implan...

There are more than 30,000 orthopedic implant revision surgeries necessary each year in part due to poor implant fixation with juxtaposed bone. A further emphasis on the current problems associated with insufficient bone implant performance is the fact that many patients are receiving hip implants earlier in life, remaining active older, and that the human lifespan is continuously increasing. C...

ubiquicidin (ubi) [29-41] is a synthetic cationic antimicrobial peptide that preferentially binds to bacterial cell membrane at the site of infection. we aimed to assess diagnostic value of 99mtc-ubi [29-41] as a radiopharmaceutical in differentiation of bacterial infection from sterile inflammation in suspected orthopedic implants. nine patients suspected for orthopedic implant infection, all ...

Biomechanical influences on bone structure play an important role in the longevity of bone around an implant. The quantity and direction of applied force influence the implant and cause deformation of the bone. FEA was used to analyze the changes in the bone on loading the implant with orthodontic force in oblique and vertical directions and orthopedic force. The Mini-implants used in the prese...

In the past, synthetic conventional materials have not served as satisfactory implants. As an example, the current average lifetime of an orthopedic implant (such as hip, knee, ankle, etc.) is only 10 to 15 years. Clearly, such conventional materials (or those materials with constituent dimensions greater than 1 micron) have not invoked suitable cellular responses to regenerate enough bone to a...

Patients with osteoporosis and joint disabilities represent a constant growing and challenging population to be treated in the musculoskeletal clinical field. Especially in the case of total hip arthroplasty, new solutions should be developed to compensate for the double negative factors, peri-implant osteolysis, and osteoporotic bone loss, affecting the quality of implant outcome. The goal of ...

Prolonged life expectancy also results in an increased need for high-performance orthopedic implants. It has been shown that a compromised tissue-implant interface could lead to adverse immune-responses and even the dislodging of the implant. To overcome these obstacles, our research team has been seeking ways to decrease the risk of faulty tissue-implant interfaces by improving the biocompatib...

The steadily increasing demand for orthopedic surgeries and declining rates of reimbursement by Medicare and other insurance providers have led many hospitals to look for ways to control the cost of these surgeries. We reviewed administrative records for a 1-year period and recorded total number of surgical cases, number of cases in which an implant was wasted, and cost of each wasted implant. ...
