Abstract:
Objective:To analyze the clinical efficacy of two-stage total hip arthroplasty in the treatment of chronic septic hip arthritis.Methods:From January 2008 to March 2020, 17 patients with chronic septic hip arthritis (17 hips) received two-stage total hip arthroplasty at Department of Orthopaedic Surgery, The First Affiliated Hospital to of Fujian Medical University. They were 11 males and 6 females, with an average age of 54.5 years (from 19 to 77 years) and 9 left and 8 right hips affected. There were 10 cases of primary septic hip and 7 cases of secondary infection after hip surgery. Three patients had undergone debridement in other hospitals and one patient had developed a sinus tract. In the first stage operation, the diseased femoral head and neck were resected to implant an articulating spacer after thorough debridement; in the second stage operation, the spacer was removed to implant a uncemented artificial hip prosthesis in 16 cases or a cemented artificial hip prosthesis in one case. Recorded were the results of microbial culture, operation time, intraoperative blood loss, and therapeutic outcomes of the patients.Results:Pathogenic data were available in 13 patients and the culture was negative in 4. The pathogens were detected by metagenomic next-generation sequencing in 2 patients with culture negative. In the first stage operation, operation time averaged 140.6 min (from 90 to 176 min) and intraoperative blood loss 361.8 mL(from 100 to 1 000 mL); in the second stage operation, operation time averaged 130.3 min (from 91 to 166 min)and blood loss 291.2 mL(from 50 to 700 mL). The average interval between the first and the second stage operations was 115.0 days(from 66 to 227 d). During the interval, spacer fracture occurred in one case, spacer dislocation in one case and lower extremity deep venous thrombosis in one case. All the patients were followed up for 12 to 82 months (average, 36.7 months) after second stage operation. The inflammatory indexes decreased to normal in all the 17 patients and infection recurrence was observed in none of them.Conclusions:Two-stage total hip arthroplasty may result in a high rate of successful treatment of chronic septic hip arthritis. Specific use of sensitive antibiotics after identification of specific pathogenic microorganisms by multiple methods is the key to a successful treatment.
