To determine the incidence of periprosthetic femoral fractures during the operation in primary hip arthroplasties and correlate them with the inherent risk factors associated with patients, implants, and the diagnosis of coxarthrosis and/or femoral neck fractures. Cross-sectional study, with retrospective analysis of medical records and image exams of patients operated between 2014 and 2019. The variables analyzed followed those proposed by the world literature, namely: age, sex, Dorr index, surgical indication, Vancouver classification, location, type of fixation (cemented or non-cemented), implant model used, intraoperative diagnosis, and corresponding treatment approach.

From July to November 2021, patients on the THA waiting list were interviewed during outpatient consultations. To compare the groups regarding categorical variables, the Chi-square test or Fisher's exact test was applied, and for quantitative variables the Mann-Whitney test was applied.

Methods: The pre- and postoperative CE angle of Wiberg and acetabular index of 14 hips operated at a tertiary hospital in Curitiba, Paraná, Brazil were evaluated.
Results: The postoperative measurements showed significant differences in relation to the preoperative period.
Objective: To radiographically evaluate the quality of cementation and implantation technique using a polished, triple-tapered femoral stem in total hip arthroplasty (THA).
Method: Retrospective study with radiographic evaluation of 86 hips in 83 patients who underwent to primary THA with the triple-tapered cemented femoral stem C-Stem (DePuy Orthopedics, Warsaw, Indiana). Cases with at least one-year of follow-up were included, and data related to preoperative, immediate postoperative, and late postoperative radiographic evolution were recorded.
Objective: This is an experimental study with the objective of analyses the increase of rigidity in synthetic tibia bones with external fixators, with single and double connecting rods and with stable and unstable fracture patterns.
Methods: The external fixators were used in the monoplanar, half pin configuration submitted to an axial compression load using the connecting bar in different patterns. Forty-eight similar models to the human tibia had been used.
