Morbidity and Mortality Analysis in the Treatment of Intertrochanteric Hip Fracture with Two Fixation Systems: Dynamic Hip Screw (DHS) or Trochanteric Fixation Nail Advance (TFNA).

BACKGROUND: The aim of this study was to compare the clinical outcomes, complications, and mortality of patients with intertrochanteric hip fracture treated with dynamic hip screw (DHS) vs. trochanteric fixation nail advance (TFNA). METHODS: We evaluated 152 patients with intertrochanteric fractures concerning age, sex, comorbidity, Charlson Index, preoperative gait, OTA/AO classification, time from fracture to surgery, blood loss, amount of blood replacement, changes in gait, full weight-bearing at hospital discharge, complications, and mortality. The final indicators encompassed the adverse effects linked to implants, postoperative complications, clinical healing or bone healing duration, and functional score. RESULTS: The study included a total of 152 patients, out of which 78 (51%) received DHS treatment and 74 (49%) received TFNA treatment. The results of this study show that the TFNA group demonstrated superiority (p < 0.001). However, it should be noted that the TFNA group had a higher frequency of the most unstable fractures (AO 31 A3, p < 0.005). Full weight-bearing at discharge also decreased in patients with more unstable fractures (p = 0.005) and severe dementia (p = 0.027). Mortality was higher in the DHS group; however, a longer time from diagnosis to surgery was also observed in this group (p < 0.005). CONCLUSIONS: The TFNA group has shown a higher success rate in achieving full weight-bearing at hospital discharge when treating trochanteric hip fractures. This makes it the preferred choice for treating unstable fractures in this region of the hip. Additionally, it is important to note that a longer time to surgery is associated with increased mortality in patients with hip fractures.

Surgical site infection in hip arthroplasty in a 10-year follow-up prospective study: Risk and factors associated.

BACKGROUND: The increased demand for hip arthroplasty means a growing number of postsurgical complications. This study aims to assess the risk of surgical site infection (SSI) in a teaching hospital; develop regional, national and international external comparisons; and evaluate SSI-related risk factors, particularly according to the timing of surgery (urgent/unplanned or elective). METHODS: Prospective cohort study from January 2008 to December 2018. Patients were followed up to 90 days after surgery. Primary endpoint was SSI incidence according to the Centers for Disease Control and Prevention criteria. Multivariate analysis was conducted to find independently associated SSI risk factors. The association between risk factors and SSI incidence was assessed by reference to odds ratio (OR). Analyses were also performed among urgent/unplanned and elective patients to identify whether SSI risk factors differed between groups. RESULTS: The study population (n = 1,808) has an overall SSI rate of 3.0% (95% confidence interval [CI]: 2.4-3.9). Timing of surgery caused an effect modification, so surgery duration> 75th percentile (OR: 3.8; 95% CI: 1.5-9.8) and inadequate preparation (OR: 3.3; 95% CI: 1.1-10.0) were independent risk factors in the urgent/unplanned group; National Healthcare Safety Network risk index≥ 2 (OR: 6.3; 95% CI: 0.1-19.2) and transfusion (OR: 3.6; 95% CI: 1.1-11.9) in the elective group. CONCLUSIONS: Hospital infection surveillance systems allow identifying risk factors susceptible to change. Characterization of factors that caused an effect modification is key to identify areas of quality improvement, including reducing operating times, preventing perioperative blood transfusion, or improving patient preparation before surgery.

Eficacia y seguridad del ácido tranexámico tópico en la artroplastia de rodilla / Efficacy and safety of topical tranexamic acid in knee arthroplasty

Introducción y objetivo: La administración de ácido tranexámico (ATX) es efectiva reduciendo la pérdida de sangre en la artroplastia de rodilla. Con el fin de evitar los efectos adversos de la administración intravenosa, se ha propuesto el uso tópico del mismo. Nuestro objetivo es evaluar la eficacia y seguridad de ATX tópico para reducir la hemorragia postoperatoria en la artroplastia de rodilla. Material y métodos: Un total de 90 pacientes intervenidos de artroplastia total de rodilla unilateral fueron incluidos en un estudio prospectivo y aleatorizado. Todas las intervenciones fueron llevadas a cabo bajo anestesia espinal, con isquemia preventiva y bajo el mismo régimen postoperatorio. Los pacientes fueron divididos en 3 grupos en función de la administración del ATX: grupo A (n=30) 1g de ATX tópico; grupo B (n=30) 1g de ATX intravenoso, y grupo C o control (n=30), al que no se administró ningún fármaco. Se analizaron los parámetros de pérdida de sangre y débito de drenajes en los 3 grupos. Resultados: Los resultados mostraron que el descenso del nivel de hemoglobina fue menor en el grupo A (1,95dl) respecto el grupo B (2,25g/dl) y el grupo C (2,96g/dl), p<0,01. Respecto a la hemorragia postoperatoria, también fue inferior en el grupo A (195ml) respecto el grupo B (466ml) y el grupo C (718ml), p<0,01. No hubo diferencias en las complicaciones y la tasa de transfusiones de sangre entre los 3 grupos. Conclusiones: La aplicación tópica de 1g de ATX reduce significativamente la pérdida de sangre en pacientes intervenidos de artroplastia total de rodilla, en mayor magnitud que la aplicación intravenosa y la no administración

Introduction and objective: Tranexamic acid (TXA) is commonly used to control postoperative blood loss in total knee arthroplasty. In order to avoid adverse effects associated with intravenous administration, topical use has been proposed as an alternative. Our aim was to evaluate the efficacy and safety of topical TXA in total knee arthroplasty. Material and methods: A total of 90 patients scheduled for unilateral total knee arthroplasty were included in a prospective randomised study. All surgeries were performed under spinal anaesthesia, tourniquet and the same postoperative protocol. Patients were allocated to one of the 3 groups according to the application of TXA: group A (n=30) 1g of topical TXA; group B (n=30) 1g of TXA intravenous and in group C or the control group (n=30) no drug was administrated. Parameters related to blood loss and drain outputs were compared between the 3 groups. Results: The results revealed that post-operative decrease in haemoglobin level was significantly lower in group A (1.95g/dL) than group B (2.25g/dL) and group C (2.96g/dL), P<.01. Total postoperative blood loss was lower in group A (195mL) than group B (466mL) and group C (718mL), P<.01. There was no significant difference in complications and allogenic blood transfusion rate between the 3 groups. Conclusions: According to the results, topical application of 1g TXA significantly reduced blood loss in patients undergoing total knee arthroplasty more than intravenous or no administration of TXA
