Comparative study of biomodels manufactured using 3D printing techniques for surgical planning and medical training.

Objectives: To obtain 3D printed bone models with a haptic sensation similar to that of the real bone, which will help the surgeon to learn and improve based on practice.

Methods: From computed tomography, 3 digital anatomical models of the human proximal femur were created and, by modifying the printing parameters, both cortical and trabecular tissues were simulated, which were combined in a different cortico-cancellous interface depending on the bone segment. The 3 equivalent models obtained were compared with a commercial Sawbone synthetic model and subjected to a series of blind surgical practice trials performed by 5 TOC specialists from a hospital, each of them with different degrees of expertise.

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.

Role of the orthopaedic surgeon in 3D printing: current applications and legal issues for a personalized medicine.

3D printing (I3D) is an additive manufacturing technology with a growing interest in medicine and especially in the specialty of orthopaedic surgery and traumatology. There are numerous applications that add value to the personalised treatment of patients: advanced preoperative planning, surgeries with specific tools for each patient, customised orthotic treatments, personalised implants or prostheses and innovative development in the field of bone and cartilage tissue engineering. This paper provides an update on the role that the orthopaedic surgeon and traumatologist plays as a user and prescriber of this technology and a review of the stages required for the correct integration of I3D into the hospital care flow, from the necessary resources to the current legal recommendations.

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.
