Hip Fractures ,Risk Factors ,Humans ,Comorbidity ,Poverty ,Hospitals ,Retrospective Studies - Abstract
Hip fracture are an important cause of morbidity and mortality in old patients. The one-year mortality after a hip fracture increase between 14 to 47%. The main objective was to analyze the risk factors associated with mortality after a hip fracture in a low-income population.Retrospective study of patients with traumatic hip fracture in a four-year period in an orthopedic training hospital. The data collected was age, gender, Charlson comorbidity index (CCI), delay time in days for surgery, duration in hours for surgical procedure, transfusion. Two groups were analyzed, alive patients and deceased patients.A total of 96 patients with traumatic hip fracture was analyzed. Mortality rate in the first year was pf 16.6%, and at the end of the follow-up was 32.2%. The alive patients showed better values of CCI with a value of 4.2 ± 1.1 versus 5.2 ± 1.0 in the deceased patients. When compared delay time for surgery and duration of surgical procedure did not observe significant difference between patients alive and deceased.The delay time of surgery did not affect the mortality after a traumatic hip fracture in old patients with economic low-income.Las fracturas de cadera representan una causa importante de morbimortalidad en los adultos mayores. La mortalidad a un año posterior a una fractura de cadera incrementa entre 14 y 47%. El objetivo de este estudio fue analizar los factores de riesgo que impactan la tasa de mortalidad posterior a una fractura de cadera en una población de bajos recursos.Se analizaron de manera retrospectiva pacientes con fractura de cadera traumática en un período de cuatro años en un hospital universitario con entrenamiento ortopédico. Los datos recolectados incluyeron edad, género, índice de comorbilidad de Charlson (CCI), tiempo en días para la cirugía y duración del procedimiento quirúrgico, así como necesidad de transfusión. Se analizaron dos grupos, pacientes vivos y pacientes fallecidos.Se evaluó un total de 96 adultos mayores con fractura de cadera. La tasa de mortalidad durante el primer año fue de 16.6%, mientras que al final del seguimiento fue de 32.2%. El grupo de sobrevivientes presentó una mejor evaluación de acuerdo con el CCI con valor de 4.2 ± 1.1 versus 5.2 ± 1.0 en los pacientes fallecidos. No se encontró diferencia estadísticamente significativa en la mortalidad entre ambos grupos al comparar los días de espera de tiempo quirúrgico y la duración de la cirugía.El retraso de la cirugía no afecta la tasa de mortalidad después de una fractura de cadera en pacientes de edad avanzada con bajo ingreso económico.

Pyomyositis is a term that denotes pyogenic infection usually primary skeletal muscle, associated with hematogenous dispersion due to transient bacteremia, or penetrating trauma, usually forming abscesses. Classically described frequently in tropical areas and predominantly affecting the lower limb musculature, however, in recent decades it has increasingly been associated with areas of temperate climates and relatively more frequently in immunosuppressed patients, being the patients under 30 years the most affected.Male of 15 years without relevant medical history. The patient had no history of trauma, falls, surgical interventions, infections or any other systemic condition. He came because of a clinical picture of 7 days of evolution characterized by pain referred to the groin and left iliac crest area associated with claudication and hyperthermia not quantified, which yielded partially to NSAIDs and paracetamol, but without achieving improvement so it is taken emergency by relatives.It is necessary to bear in mind this pathology when performing the differential diagnostic approach of a patient presenting with pain and functional limitation of some joint associated with data suggestive of an infectious or inflammatory process.La piomiositis es un término que denota infección piógena por lo general primaria de músculo esquelético. Clásicamente descrita de manera frecuente en zonas tropicales y en pacientes inmunocomprometidos; sin embargo, en las últimas décadas se observa cada vez más en zonas de climas templados y con relativa mayor frecuencia en pacientes inmunocompetentes, siendo el grupo etario más afectado el de menores de 30 años.Masculino de 15 años sin antecedentes médicos de relevancia. Acude por presentar cuadro clínico de siete días de evolución caracterizado por dolor referido en ingle y zona de la cresta ilíaca izquierda asociado a claudicación e hipertermia no cuantificada, que cedían parcialmente a AINES y paracetamol, pero sin lograr mejoría, por lo que es llevado a urgencias por familiares.Es necesario tener en mente esta patología al momento de realizar el abordaje diagnóstico diferencial de un paciente que se presenta con dolor y limitación funcional de alguna articulación asociada a datos sugestivos de un proceso infeccioso o inflamatorio.

Distal femur pseudoarthrosis also called «distal femur non-union» (DFNU) represents a rare complication associated with a fracture caused by high-energy trauma; its treatment is controversial, as there is a wide variety of surgical techniques that can be implemented, from open reduction plus internal fixation with plates, to the use of fixed angle plates combined with bone autograft. We expose the case of a 24-year-old man who shows up for consultation with the history of having presented a left femoral supracondylar fracture with a year of evolution, treated by osteosynthesis of the distal femur with dynamic condylar screws (DCS plate); developed a torpid evolution with severe pain in the distal third of the left thigh and functional limitation, developed a progressive varus deformity of the left thigh that caused a shortening of 3.8 cm of the limb. A focus of pseudoarthrosis was identified, which was surgically removed, the intramedullary canal was recanalized, and a lateral closed wedge osteotomy was performed to correct the angulation and allow reduction. 5.5 mm (three proximal and three distal) hydroxyapatite screws and an external fixator were placed. In addition, a review of the literature focused on the use of external fixation was carried out as a treatment for the pseudoarthrosis of the distal femur.La seudoartrosis del fémur distal, también llamada «no unión del fémur distal» (NUFD), representa una complicación poco frecuente asociada a una fractura causada por un traumatismo de alta energía; su tratamiento es controversial, ya que existe una gran variedad técnicas quirúrgicas que pueden ser implementadas desde la reducción abierta más la fijación interna con placas hasta el uso de placas de ángulo fijo combinadas con autoinjerto óseo. Exponemos el caso de un hombre de 24 años de edad, el cual se presenta a la consulta con el antecedente de haber sufrido una fractura supracondílea femoral izquierda con un año de evolución, tratada mediante una osteosíntesis del fémur distal con tornillos condilares dinámicos (placa DCS); mostró una evolución tórpida con dolor severo en el tercio distal del muslo izquierdo y limitación funcional, desarrolló una deformidad en varo progresiva del muslo izquierdo que causó un acortamiento de 3.8 cm de la extremidad. Se identificó un foco de seudoartrosis, el cual se retiró quirúrgicamente, se recanalizó el canal intramedular y se realizó una osteotomía de cuña cerrada lateral para corregir la angulación y permitir la reducción. Se colocaron tornillos de hidroxiapatita de 5.5 mm (tres proximales y tres distales) y un fijador externo. Además se hizo una revisión de la literatura enfocada en el uso de la fijación externa como tratamiento de la seudoartrosis del fémur distal.
