  Total ankle arthroplasty: optimizing computed tomography imaging protocol Total ankle arthroplasty: optimizing computed tomography imaging protocol Kohonen, Ia; Koivu, Helka; Vahlberg, Tero; Larjava, Heli; Mattila, Kimmo CT is a reliable imaging method to evaluate periprosthetic bone structure around ankle prostheses when orientation of the prosthesis . A periprosthetic hip fracture is a broken bone that occurs around the implants of a total hip replacement. It is a serious complication that most often requires surgery. Although a fracture may occur during a hip replacement procedure, the majority of periprosthetic fractures occur after a patient has spent years functioning well with a hip.

COVID has affected us in so many ways, such as more people working from home, and everyone wearing masks. There are some health related risks related to working from home if you don't have the correct set up and posture, and similar risks from how you may be functioning with your mask on. Normal appearance of total ankle arthroplasty (TAA) as seen on computed tomography. Coronal (A) and sagittal (B) computed tomographic images ( kVp with rotation time of seconds and collimation of 20 mm using gemstone spectral imaging, 2-mm thickness) show normal appearance of Mobility TAA.

  Immune response to implants is commonly reported in the literature and can include hypersensitivity related to pacemakers, dental implants, and orthopedic hardware. Furthermore, up to 13% of people are sensitive to nickel, cobalt, or chromium. A total ankle replacement is a joint replacement surgery of the ankle joint. Total ankle replacements have been available for more than 30 years—but early designs were failures. In the s, ankle replacements were touted as promising—but by the s ankle replacements were rarely performed due to their high failure rate.

The major longer term complications of ankle arthroplasty are periprosthetic osteolysis and aseptic loosening. Follow-up studies of total hip arthroplasties show that measurements of periprosthetic osteolytic lesions on radiographs underestimate the size compared with those made on computed tomography (CT), and some of the lesions may even remain undetected on by: Computed tomography (CT) was conducted on 25 ankles that exhibited progression of osteolysis.

Nonetheless, its effect on patient quality of life is substantial. Various treatment options are available for ankle arthritis. Total ankle arthroplasty (TAA) is an effective alternative to ankle arthrodesis, with the benefit of equal pain relief, preservation of joint motion, and possibly improved function (1,2,3,4).

Total ankle replacement has been associated with great advancements since its conception several decades ago; however, implant failure remains a known complication and sometimes anticipated outcome 1, 2, common culprit for total ankle replacement failure has been aseptic loosening and resultant osteolysis 4, 5, 6, ment of failed total ankle replacement includes.

Computed tomography scan of the same ankle demonstrating the underestimation of osteolysis from plain radiographs. Osteolysis with Component Migration When assessing for component migration, it is necessary to understand the mechanical properties of the implant designs, in addition to understanding the relevant failure mechanisms.

In contrast to osteolysis around hip arthroplasty, factors other than polyethylene debris, such as reaction to necrotic tissue, micromotion at the implant-bone interface, and high fluid pressure may play a key role in osteolysis around total ankle replacement.

To evaluate parameters and positioning when imaging total ankle prostheses on computed tomography (CT). An ankle prosthesis implanted into a pig’s knee joint underwent 16 different CT imaging protocols. Four defects were drilled around prosthesis components simulating periprosthetic osteolytic lesions.

The specimen with the implant was imaged in four different orientations with the. replacement (TAR). The results of total ankle replacement have improved over the recent decades, but challenges remain. Peri-implant osteolysis has been major problem, as it compromises the stability of the implant components and can lead to aseptic loosening and implant failure.
