Paciente politraumático con fractura de pelvis: factores y lesiones asociados a la mortalidad / Pelvic fracture in the patient with multiple injuries: factors and lesions associated with mortality

Objetivo. El principal objetivo de este estudio es identificar aquellos factores demográficos, clínicos, analíticos o lesiones asociadas relacionados con la mortalidad a 30 días. Método. Estudio observacional con recogida prospectiva de datos de pacientes politraumáticos (PPT) con fractura de pelvis (FP) asociada entre enero de 2009 y enero de 2017. Se recogieron variables demográficas, clínicas y analíticas a la llegada al servicio de urgencias, tipo de fractura pélvica, procedimientos terapéuticos, lesiones asociadas y mortalidad a los 30 días. Se realizó un análisis de asociación uni y multivariable. Resultados. Se atendieron 2.061 PPT, de ellos 118 presentaban FP. La mortalidad a los 30 días fue del 12,7% (15 PPT). El 23,7% ingresaron con una presión arterial sistólica 90 mmHg, el 41,52% con frecuencia cardiaca > 100 lpm, 67,6% con lactacidemia 20 mg/dl y el 26,3% con un exceso de base (EB) -6. El Injury Severity Score medio fue de 20 puntos. Requirieron angiembolización el 80,6% y packing preperitoneal el 3,4%. Las principales lesiones asociadas fueron: fracturas costales (35,6%), hemo-neumotórax (31,3%), lesiones de raquis (35,6%) y traumatismo craneoencefálico (30%). Los factores independientes asociados a la mortalidad fueron: la edad, el sexo femenino, las fracturas complejas (Tile C), un lactato 20 mg/dL, un EB -6 y la asociación a perforación intestinal. Conclusiones. Se identifican 6 factores independientes relacionados con la mortalidad a 30 días de los PPT con FP (AU)

Background and objective. The main objective of this study was to identify demographic, clinical, analytical factors or injuries associated with 30-day mortality in patients with pelvic fractures. Methods. Prospective observational study of patients with multiple injuries including pelvic fractures between January 2009 and January 2017. We recorded demographic, clinical, and laboratory data on arrival at the emergency department; type of pelvic fracture; treatments; associated lesions; and 30-day mortality. Univariable and multivariable models were used to analyze the data. Results. A total of 2061 multiple-injury patients were attended; 118 had pelvic fractures. Fifteen of the patients with pelvic fractures (12.7%) died within 30 days. Arterial blood pressure on admission was less than 90 mm Hg in 23.7%, heart rate was over 100 beats per minute in 41.52%, lactic acid level was 20 mg/dL or higher in 67.6%, and base excess of -6 or less was recorded for 26.3%. The mean Injury Severity Score was 20 points. Angiographic embolization was required in 80.6% and preperitoneal packing in 3.4%. The main associated lesions were rib fractures (35.6%), hemo-pneumothorax (31.3%), spinal injuries (35.6%), and head injuries (30%). Conclusions. The 6 independent variables associated with risk of death in multiple-injury patients with pelvic fractures are age, female sex, complex fractures (Tile type C), lactic acid level of 20 mg/dL or more, base excess of -6 or less, and bowel perforation (AU)

High short-term loosening rates with the Wagner Standard Cup.

The stability of prosthetic fixation is to a large extent dependent on component design. The purpose of this study is to analyze the short-term radiological results obtained with the Wagner Standard Cup in primary hip arthroplasty. An assessment was made of one hundred primary hip arthroplasties. The radiological evaluation revealed bone ingrowth in 37 of cases, fibrous integration in 49 and loosening in 14. In summary, osseointegration of the Wagner Standard Cup was unsuccessful in a high percentage of cases. This finding, which was unrelated to the type of stem or bearing surface used, bore a statistically significant relation (P<0.05) with an observed poor bone coverage of the acetabular component. Although insufficient bone coverage could arguably be attributable to a poor surgical technique, we would tend to agree with other authors that it is rather likely to result from a flawed implant design that impedes osseointegration.
