摘要：

To ensure that the femoral stem is placed in the proper position during total hip arthroplasty, the authors developed a patient-specific instrument. A total of 10 total hip arthroplasties were performed with the assistance of the patient-specific instrument during this study. The mean accuracy of stem tilt, varus/valgus, and anteversion was 2.1 degrees +/- 4.1 degrees, 1.0 degrees +/- 0.7 degrees, and 4.7 degrees +/- 1.2 degrees, respectively. No complications were observed and no reoperations were required for any of the patients who underwent surgery included in this study. The results support the feasibility of this patient-specific instrument for use during stem placement in total hip arthroplasty.
