Abstract:

BACKGROUND: Hip arthroplasty has become mature, but infection after arthroplasty is a serious complication.

OBJECTIVE: To analyze the clinical characteristics and treatment outcomes of infection after hip arthroplasty, thus providing reference for improving the diagnosis and treatment of postoperative infection.
METHODS: A computer-based online search of CNKI, WanFang, PubMed and Medline databases from 2006 to 2016 was conducted using the keywords of “hip arthroplasty, infection” in English and Chinese, respectively. Clinical data of 20 patients with infection after hip arthroplasty in three hospitals from January 2006 to January 2016 were analyzed retrospectively.
RESULTS AND CONCLUSION: (1) Two-stage revision is considered to be the main method for treating infection after hip arthroplasty. The duration of antibiotic therapy remains controversial. The increased bacterial resistance is difficult, especially the widespread use of vancomycin after hip arthroplasty. (2) Staphylococcus aureus is the highest proportion of strains detected, up to 30%, followed by 25% for staphylococcus epidermidis, 20% for coagulase-negative staphylococcal and 75% for staphylococcus in the three hospitals. Gram-negative bacteria mainly contain pseudomonas aeruginosa, enterobacter cloacae and hemolytic streptococcus. (3) To conclude, antibiotics should be timely adjusted according to antibiotic susceptibility results after hip arthroplasty.
