Abstract:

Objective To evaluate the short-term effect of one-stage and staged artificial joint replacement in the treatment of active hip tuberculosis.Methods The clinical data of 25 patients with active hip tuberculosis admitted to Chengdu Public Health Clinical Medical Center from January 2013 to December 2016 were analyzed retros-pectively. There were 15 males and 10 females, aged 23-77 years, with an average age of (50.3±2.1) years. Sixteen patients were operated with primary tuberculosis focus clearance and artificial joint replacement (stage Ⅰ), 9 patients with primary tuberculosis focus clearance and stage artificial joint replacement (stage Ⅱ). At 1, 2, 3, 6, 12, 18, and 24 months follow-up, the X-ray and CT were carried on, and the Harris hip function score was calcula-ted to evaluate the initial fixation, early survival and tuberculosis recurrence.Results Twenty-five cases were followed up. The preoperative Harris hip function score was (46.7±7.6) and (88.2±4.2) at 3 months follow-up. The difference was statistically significant (t=-12.745, P<0.001). During the follow-up period, the X-ray films of 25 patients showed that the femoral stalk and femur were well matched, and no loosening or subsidence of the femoral stalk were observed. Twenty-five patients were not complicated infection, deep vein thrombosis, pulmonary embolism and also they weren’t observed tuberculosis recurrence.Conclusion One-stage and staged arthroplasty have a effective short-term effect in the treatment of active hip tuberculosis.
