Markers of thrombin generation during resurfacing and noncemented total hip arthroplasty: a pilot study.

Background: Hip resurfacing arthroplasty (HRA) could be associated with an increased risk of deep vein thrombosis (DVT) compared to traditional noncemented THA because it involves greater dissection, increased kinking and distortion of the femoral vessels, takes longer to perform, and involves insertion of some cement into the femur.

Questions/purposes: Does HRA lead to greater risk of thromboembolism compared with noncemented THA?

Methods: We prospectively studied 20 patients receiving HRA and 20 receiving THA. All patients were younger than 67 years old and were similar in height, weight, American Society of Anesthesiologists status, and gender mix.
