Abstract:Objective To analyze the curative effect of new irrigation pump in the treatment of tibia chronic osteomyelitis. Methods Thirty-nine cases of chronic tibial osteomyelitis, on the basis of thorough debridement,were treated with self-made irrigation pump. The patients were followed up for their general conditions and laboratorytests, and their knee function and ankle function were evaluated by HSS score and Baird-Jackson score. Results All patients were followed up. The general status, local situation and laboratory test results were significantly improved,the HSS score of knee function and the Baird-Jackson score of ankle function before and after treatment were significantly different (P < 0.05). Conclusions The self-made new type irrigation pump is simple and controllable,and has definite curative effect on chronic osteomyelitis, which can be further popularized.
