Revision for infected total hip arthroplasty / 中华创伤骨科杂志

ABSTRACT

Objective To discuss operative treatment of the postoperative infection after total hip arthroplasty. Methods 11 cases of infected hip arthroplasty, 6 males and 5 females, with a mean age of 63 years old (from 54 to 71 years), were treated operatively in our department. Their preoperative mean Harris score was 33 (from 25 to 40), and their mean erythrocyte sedimentation rate (ESR) was 61 mm/h (from 34 to 80 mm/h). Bacterial cultures and drug susceptibility tests were carried out before and during operation. One- stage revision was performed for 6 cases, and two- stage revision was performed for 5 cases. Of the 11 cases, 2 were classified as early postoperative infection and 9 as late chronic infection. Preoperative microorganism cultures of joint aspiration or pus in sinus were positive in 8 cases but negative in 3 cases. 5 had staphylococcus epidermidis infection, 2 had escherichia coli infection and 1 had staphylococcus aureus infection. Results No recurrence of infection was found after a mean follow- up period of 17 months (from 12 to 31 months). ESR and blood tests after operation revealed nothing abnormal. The mean Harris score increased significantly to 84.2 (from 79 to 92) after revision (P
