Pararectus Approach in Acetabular Fractures in Patients Older Than 65 years. Is it Possible to Improve the Technique?

Objectives: Review clinical results of the treatment for acetabular fractures using the pararectus approach and analyze surgical variations of the traditional approach.

Design: Retrospective.

Setting: Tertiary referral hospital.

Analysis of mortality after surgical treatment of periprosthetic distal femur fractures.

Introduction: The incidence of periprosthetic fractures of the knee is increasing due to the increase in the number of total knee arthroplasties performed, together with population aging. We found few studies that analyze mortality in our setting after surgery. Our objective was to evaluate mortality and survival after surgical treatment of periprosthetic fractures of the distal femur in our environment.

Surgical treatment of periprosthetic humerus fractures and algorithm.

Introduction: Periprosthetic humerus fractures are infrequent and sometimes difficult to treat. There is limited literature and no consensus on the handling of these fractures. The objective of this study was to compare our results with those published in the literature, in order to improve our care and propose a management algorithm.

Comparison of methods for assigning the material properties of the distraction callus in computational models.

In silico models of distraction osteogenesis and fracture healing usually assume constant mechanical properties for the new bone tissue generated. In addition, these models do not always account for the porosity of the woven bone and its evolution. In this study, finite element analyses based on computed tomography (CT) are used to predict the stiffness of the callus until 69 weeks after surgery using 15 CT images obtained at different stages of an experiment on bone transport, technique in which distraction osteogenesis is used to correct bone defects.

Talus fractures. Functional results for polytraumatized patients.

Talar fractures are uncommon lesions (0.1-0.9%) and have a high rate of complications.
