Dual mobility cup in hip fracture: Indications and clinical results compared with bipolar hip arthroplasty.

Introduction: The choice between hemiarthroplasty (HA) and total hip arthroplasty (THA) for displaced femoral neck fractures remains debated. There is increasing use in dual mobility cup total hip arthroplasty (DMC-THA) to prevent dislocations in these high-risk patients. Aim of this study is to retrospectively analyze patients treated in a single Center for femoral neck fracture comparing HA and DMC-THA in terms of: functional outcome, rate of complications and mortality.

Severe Open Dislocation of the Hip with Exposed Femoral Head: A Case Report.

Case: A 54-year-old woman was brought to our emergency department with an inferomedial open hip dislocation without fracture secondary to a railway trauma. We performed hip reduction, wound debridement, and stabilization with external fixation. After 7 months, hip arthroplasty was performed for severe hip instability and avascular necrosis of the femoral head.

Synthesis and A1-adenosine receptors affinities of purino[7,8-c]quinazoline-8,10(9H,11H)-diones as rigid analogues of 8-arylxanthines.

Title compounds were prepared by a cyclocondensation reaction between 8-(2-aminophenyl)xanthines and trialkyl orthoesters. Some of them showed activities as A1-adenosine receptor antagonists with binding values in the micromolar range. Results are discussed with reference to 1,3-dialkyl-8-arylxanthines.
