title: A Patient-Specific Instrument for Femoral Stem Placement During Total Hip Arthroplasty.
abstract: 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°±4.1°, 1.0°±0.7°, and 4.7°±1.2°, 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. [Orthopedics. 2017; 40(2):e374-e377.].
