  • Effectiveness of total hip arthroplasty for hip infection sequelae

    ObjectiveTo evaluate hip function and reinfection of the patients with hip infection sequelae after total hip arthroplasty (THA) treatment.MethodsA clinical data of 31 patients (31 hips) with hip infection sequelae, who were treated with THA between June 2010 and May 2017, was retrospectively analyzed. There were 18 males and 13 females, with an average age of 46.1 years (range, 20-71 years). There were pyogenic infection in 17 cases, tuberculous infection in 9 cases, and unknown source of infection in 5 cases. The average time from infection to cure was 13.9 months (range, 6-25 months). The average time from cure to operation was 23.4 years (range, 6-58 years) for patients with confirmed source of infection. According to Kim classification, 12 cases were rated as typeⅠ, 9 as typeⅡ, and 10 as type Ⅲ. There were 21 cases of osteoarthritis after dysplasia, 7 cases of pathologic dislocation, and 3 cases of hip ankylosis. After operation, the infection was assessed by physical signs and laboratory tests; X-ray film of the hip was taken to assess the skeletal structure of the hip and infectious lesion; the length of the lower limb was measured, and the function of the hip joint was evaluated by Harris score.ResultsAll patients were followed up 10-63 months (mean, 34 months). The result of bacterial culture was negative. The incisions healed by first intention. The sciatic nerve stimulation occurred in 1 case and posterior dislocation of the joint occurred in 1 case after operation. There was no recurrence of infection and no aseptic loosening of the prosthesis. According to Harris score, the function of the hip was rated as excellent in 8 cases, good in 19 cases, and fair in 4 cases at last follow-up; and the excellent and good rate of hip joint function was 87%. X-ray films showed no patchy bone density reduction, spot hardening, or light areas. The length of affected limb was not fully equal with the unaffected limb in 5 cases, and the difference between two sides ranged from 0.4 to 1.3 cm (mean, 0.6 cm). At last follow-up, all patients had no obvious claudication or sensation of unequal length.ConclusionTHA can obtain satisfactory hip function and has low risk of infection recurrence for the patients with hip infection sequelae, who were assessed as the hip infection in a dormant state.
