Insight Into

AbstractThe aim of this study was to assess a large, single-surgeon dataset of uncemented total hip arthroplasties that had been templated using software. This assessment compared preoperative templated predictions with what was implanted with regard to (1) femoral prosthesis size and (2) acetabular cup size. The operation notes for two types of uncemented total hip arthroplasty performed by a single surgeon between January 9, 2008, and March 21, 2019, were assessed. The data were refined so that only those that were fully templated on a correctly calibrated pelvic radiograph were included. This provided a total of 153 cases. The predicted software template was compared with actual implanted component sizes. With regard to the femoral stems, the templating software was exactly correct in 45.75% of cases and was accurate to within one size in 87.59% of cases. With regard to the acetabular component, the templating software was exactly correct in 52.94% of cases and was accurate to within one size (2 mm) in 86.94% of cases. Templating software offers an accurate prediction of the size of uncemented femoral and acetabular components. In addition, the benefits of templating include cognitive rehearsal, insight into potentially challenging aspects of surgery, and highlighting intraoperative issues where there is a large intraoperative deviation from what is templated. This study demonstrates the congruence and reproducibility of templating software when compared with other smaller studies performed in the literature.

Abstract Background The purpose of this study was to review retrospectively the primary total hip arthroplasties operated upon with the cementless Wagner Self-Locking stem in patients with type C femoral bone. Methods Twenty-eight total hip arthroplasties were performed in 25 patients aged ≥ 60 years using a cementless Wagner Self-Locking femoral component between 2006 and 2011. According to Dorr’s criteria, all 28 femora were classified as type C bone. All patients were treated with THA using a cementless Wagner cone prosthesis. Clinical and radiologic evaluations were performed on all patients. Results Mean follow-up period was 125 ± 10.5 months (range 96 to 156 months). Average Harris hip score pre-operatively was 46 ± 9 (range 39 to 62) and at the last follow-up was 90 ± 9 (range 83 to 98). The stem to canal fill is calculated as percentages on the operative side at three distinct levels: just below the lesser trochanter, at midstem, and 1 cm above the tip of the component on anteroposterior radiograph. The mean proximal stem-to-canal fill percentages were 97% ± 2.1%, 95% ± 3.5%, and 88% ± 2.6%, respectively (anteroposterior view) and 92% ± 2.2%, 86% ± 1.9%, and 83% ± 2.5%, respectively (lateral view). Radiographic evaluation demonstrated good osteointegration of the implants in the follow-up. Conclusions Based on the long-straight cylindrical tapered stem design, the cementless Wagner SL stem can achieve reliable stability by close apposition of the stem and wide stovepipe femoral canal from metaphysis to diaphysis in type C bone.
