Abstract
A study was conducted to assess the accuracy of two-dimensional analog templating in the surgical planning for patients undergoing total hip arthroplasty using the TAPERLOC stem. We retrospectively reviewed the preoperative radiographs of 47 hips (37 females, 8 males) between 43 and 89 years of age. Forty percent of the implanted components (19/45) were estimated precisely, corresponding to the size placed intraoperatively. Sixty-six percent (31/47) were accurate to within 1 component size. Stem alignment was neutral in 44 hips and in the valgus position in 3 hips. There was no subsidence of the stem or intraoperative femoral fracture. Accurate determination of the component size for the TAPERLOC stem preoperatively is limited in analog templating.
