ARZA, Miguel Benigno et al. Digital templating in total hip arthroplasty. An. Fac. Cienc. Méd. (Asunción) [online]. 2020, vol.53, n.2, pp.37-46. ISSN 1816-8949.


Preoperative planning allows a surgical act without complications. It can be manual or digital. Its usefulness in total hip arthroplasty (ATC) is important, being digital seemingly more beneficial since it reduces surgical time and complications. The present study analyzed the effectiveness of the digital modality.

Materials and methods:

Observational, prospective, analytical study. Non-probabilistic sampling of consecutive cases attended in Department of Orthopedics and Traumatology of the Medicine Scholl (Universidad Nacional de Asunción). Patients> 18 years of age were indicated with ATC indication, between december 2018 to october 2019, with prior informed consent. Data whose characterization was made possible by means of a previously established instrument, entered in Excel basis, were released. Each patient had both types of planning: manual and digital. For TraumaCad® version 2.5 Brainlab software and King Mark® radiological markers were used for the digital. Both types of planning were compared by executing statistical analyzes with the software R.v3.4.2., being a value p <0.05, considered statistically significant.


57 patients were evaluated with the digital method and 42 with the manual. The male-female ratio was 1/1, with those in the 50-60 age group being the most affected. The most frequent reason for consultation was hip pain, with primary coxarthrosis and aseptic bone necrosis being their cause. The consultation time 1 and surgery was 12.5 days. The surgical time, the correlation between planning and results for acetabular, femoral components, were more effective with digital planning.


Digital planning compared to the manual is more effective.
