Short-stem total hip arthroplasty (THA) has gained popularity due to its bone-preserving properties and improved physiological load transmission to the proximal femur. Despite these advantages, the ability of short-stem implants to reliably restore leg length and offset remains debated. This study evaluates whether a single offset implant is sufficient for accurate anatomical reconstruction or if multiple offset options are necessary. A total of 148 anteroposterior pelvic radiographs of patients scheduled for short-stem THA were analysed using MediCAD® software. Femoral offset and leg length were measured, and the accuracy of anatomical reconstruction was assessed within a 5-mm target range. Comparisons were made between a single offset (130°) implant and a dual-offset system (130° and 119°) using the McNemar-Bowker test. With a single 130° CCD (Caput-collum-diaphyseal) offset implant, 55.7% (82/148) of cases achieved satisfactory leg length and offset restoration. The use of a dual-offset system improved accuracy to 79.1% (117/148), demonstrating a statistically significant advantage (p < 0.001). The study highlights the need for at least two CCD-angle-offset combinations in short-stem THA to address anatomical variability. A dual-offset system enhances accuracy, reduces biomechanical imbalances, and therefore we expect improvements in clinical outcomes, particularly in teaching hospitals where standardization is essential.

El choque séptico es un estado crítico en el que el paciente presenta compromiso hemodinámico, lo cual requiere de cuidados personalizados de enfermería en la unidad de cuidados intensivos (UCI). Por lo tanto, el objetivo del presente estudio de caso fue establecer las intervenciones del profesional de enfermería en un paciente con choque séptico internado en la UCI de una institución de salud del suroccidente colombiano en el año 2023. Para ello, se empleó una metodología de tipo observacional y descriptiva, en la cual se aplicó un plan de cuidados de enfermería, mediante el uso de la taxonomía NANDA-NIC-NOC; además, se realizó una valoración sistemática basada en los patrones funcionales de salud de Marjory Gordon. En este caso, se brindó cuidado de enfermería a un paciente que presentaba choque séptico secundario a peritonitis. El paciente fue tratado con antibiótico y cuidados clínicos en la UCI. Una vez ejecutadas las actividades de enfermería, se comprobó que las intervenciones fueron adecuadas para alcanzar los objetivos de cuidado propuestos. Finalmente, se concluye que el cuidado de enfermería en este tipo de paciente es indispensable y requiere de conocimientos sólidos por parte del personal de enfermería, basados en las necesidades fisiológicas y psicológicas del individuo.

ABSTRACTIn the past few years, the focus on Alum shale hazards and the need for efficient mapping tools have increased in Norway. Alum shale is highly toxic and poses a substantial obstacle to infrastructure development such as tunnel projects. We present an evaluation of the ground‐based electrical resistivity tomography, induced polarisation, and airborne electromagnetic methods for mapping purposes using a recent case study. This evaluation is done in combination with resistivity and chargeability laboratory measurements applied to drill cores. The aim of the geophysical survey was to improve the knowledge of Alum shale occurrence to assist a tunnel project in Gran, southeast Norway. Resistivity and chargeability models derived from an electrical resistivity tomography/induced polarisation survey enabled us to map the presence of Alum shale during the tunnel investigation. The resistivity models point to geological layers that are in agreement with the rock types observed from early drillings together with subsequent geological logging during tunnelling. The time‐domain chargeability models are imperfect but nonetheless reveal the presence of polarisable minerals. These are likely due to the high levels of sulphides contained in black shale. An airborne electromagnetic survey was done close to the area of interest, which enabled us to fly some sparse lines across the tunnel alignment as a piggyback survey. Although the airborne electromagnetic resolution is lower than electrical resistivity tomography, the successful test flight lines illustrate the potential of airborne electromagnetic surveys for Alum shale mapping in Norway and affirm the promise of airborne electromagnetic in the early stages of project exploration.
