Indications and clinical results of Non-Operative management of periprosthetic hip fractures in elderly patients.

Background: The increase in life expectancy in the general population has led to a rise in the use of hip arthroplasties and consequently, to an increase in the incidence of periprosthetic hip fractures (PPHF). The impact of this type of fracture on patients necessitates a personalized approach to treatment, whether surgical or non-operative, taking into account the trajectory and associated comorbidities.

Methods: We performed a retrospective study of 80 patients over the age of 70 diagnosed with a periprosthetic hip fracture between 2011 and 2018.

Dislocation and survival rate of dual mobility cups in revision total hip arthroplasty in patients with high risk of instability.

Purpose: Instability remains as an unsolved complication after revision total hip arthroplasty (rTHA). Dual mobility (DM) cups have decreased dislocation rate in rTHA; however, there are few clinical studies that evaluate the risk of dislocation after rTHA in patients with high risk of instability.

Methods: Between 2007 and 2019, 95 consecutive rTHA using a DM cup, in 93 patients with instability risk factors were retrospectively reviewed.

Killer immunoglobulin-like receptor and cancer.

Introduction: Natural killer (NK) cells play an important role in defense against tumor cells. The development and function of NK cells is governed by a dynamic balance between inhibition and activation of cell surface receptors, including KIR receptors.

Patients And Method: A case-control study is carried out that compares a group of 46 children diagnosed with malignant diseases, the control group is made up of 82 healthy children.

Posterior pelvic tilt evolution in patients undergoing total hip arthroplasty. A minimum 5-years follow-up clinico-radiological study.

Background And Objective: Pelvic tilt influences the relative position between total hip arthroplasty (THA) components. Changes in lumbar spine over time may affect clinical and radiological outcomes of THA during follow-up. We assessed the evolution of pelvic tilt and cup position after THA for a minimum follow-up of five years and the possible appearance of complications.
