RAMOS MARTINEZ, A. et al. Osteomielitis por Escherichia coli sobre fractura cerrada de húmero. []. , 23, 12, pp.588-590. ISSN 0212-7199.

^les^aLos pacientes sometidos a sondaje vesical permanente presentan riesgo de padecer episodios de bacteriemias por Escherichia coli. Se presenta el caso de un varón de 88 años portador de sonda vesical permanente que ingresó por fractura cerrada subcapital del húmero izquierdo y hematuria debida a un carcinoma de vejiga. Durante el ingreso fue sometido a lavados vesicales y a una cistoscopia. Al octavo día de ingreso presentó un incremento de la tumefacción en el hombro izquierdo. Tanto la radiografía simple como la TAC demostraron aire en la proximidad de la fractura. Se intervino al paciente comprobando la existencia de un absceso maloliente sobre la fractura. Se aisló E. coli. La osteomielitis hematógena sobre un fractura cerrada es una complicación infrecuente que puede pasar desapercibida y se acompaña de un mal pronóstico. El uso racional y selectivo del sondaje vesical podría evitar algunos casos semejantes al presentado.^len^aPatients with indwelling urethral catheters have an important risk of developing Escherichia coli bacteremia. Several cases of hematogenous vertebral osteomyelitis due to E. coli after diagnostic or therapeutic urinary tract procedures have been reported. An 88-years-old male patient with indwelling urethral catheter was admitted because of a closed subcapital humeral fracture and macroscopic hematuria due to bladder carcinoma. During his hospital admission he was treated with bladder irrigations with glycine solution. Also a cystoscopy was done. On 8th day after admission the size of his left shoulder increased. Free air in the proximity of the humeral fracture was observed at X-ray radiography and at CT scan.The patient was operated and an abscess close to the fracture with malodorous pus was drained. A culture of pus yielded E. coli. In order to prevent infections similar cases, use of indwelling urethral catheters should be strictly limited to patients that do not have any other option.
