title: [Sensitivity and antibiotic resistance in infections of the musculoskeletal system].
abstract: BACKGROUND
  Infections of the musculoskeletal system are a devastating complication for patients, due to it's long rehabilitation process and even sometimes the removal of the implant, the chronicity of infection, is often due to lack of coverage in empirical antibiotics.
  
  
  METHODS
  A retrospective, observational, descriptive cohort study was performed. All cultures form musculoskeletal system infected patients reported of sensitivity and resistance of germs isolated were analyzed.
  
  
  RESULTS
  A total of 143 positive results were included. Reported more frequent germ Staphylococcus aureus accounted for 75 positive cases, followed by Escherichia coli with 31 positive results. Antibiotics with better sensitivity according to the type of microorganisms were trimethoprim-sulfamethoxazole and vancomycin, levofloxacin and linezolid, gentamicin, erythromycin and amikacin. Regarding antibiotic resistance, those reported with the highest percentage were penicillin G, amoxicillin with clavulanic acid and ampicillin.
  
  
  CONCLUSIONS
  We recommend using empirical treatments in musculoskeletal system infections, trimethoprim-sulfamethoxazole are the best choice because they have the same sensitivity compare with vancomycin and a resistance rate of 7.6%. Betalactamics have a high percentage of resistance and low sensitivity so we must consider alternatives.
