Total loss of talus due to trauma or avascular necrosis, for example, still remains to be a major challenge in foot and ankle surgery with severely limited treatment options. Implantation of a custom made total talar prosthesis has shown promising results so far. Most important factors for long time success are degree of congruence of articular surfaces and ligamentous stability of the ankle. T...

BACKGROUND In geriatric patients with Pauwels types II and III femoral neck fractures, hemiprosthesis is the therapy of choice. OBJECTIVES This study was conducted to analyze the results after cemented hemiprosthesis placement, the first year after surgery. PATIENTS AND METHODS This retrospective study was conducted on 319 patients over 70 years with displaced femoral neck fractures treated...

The Judet acrylic femoral head hemiprosthesis was first implanted in 1946. We performed bilateral revision in one patient 45 years after implantation of a Judet prosthesis. Histological analysis of femoral neck remnants and joint capsule did not show aggressive osteoclastic bone resorption or signs of dynamic bone apposition as is frequently observed nowadays with failed total hip prostheses. O...

results from a total of 319 patients, 78% (n = 249) were female and 22% (n = 70) were male, with the mean age of 83.6 years. seventeen percent of the patients suffered from heart failure, 23% from diabetes, and 19% from renal insufficiency. time to surgery averaged one day postinjury. average operative time skin-to-skin was 50 minutes. seventy-three percent of the patients could mobilize indepe...

Introduction The DIP Argo hemiprosthesis (ADIP) was designed in 2012 with the idea of replacing the destroyed / arthritic head of the middle phalanx (P2) and was implanted in 2013 for the first time.Basically the idea was to achieve coverage of P2 as opposed to P3 (distal phalanx), because the last phalanx of the digit is so thin, and the joint surface often so destroyed that the fixation of th...
