ABSTRACT

Objective To evaluate the therapeutic effect of oral and external application of Chinese medicine combined with Ilizarov external fixator and the accordion technique for severe chronic osteomyelitis of the tibia.Methods A total of 78 patients with severe chronic osteomyelitis of the tibia were randomized into a routine treatment group and a combined treatment group, 39 in each group. All the patients in the two groups received external fixation by use of Ilizarov external fixator and the accordion technique. All the patients in the combined treatment group received oralGuyu decoction. The patients who had large wound received vacuum-sealing drainage in the routine treatment group, and vacuum-sealing drainage combined with external application ofShengji-Yuhong plaster in the combined treatment group. All the patients were treated for 8 weeks and followed up for 2 years. The time to wound healing and fracture healing, and the drainage time were compared between the two groups. Functional and radiologic findings were evaluated according to Paley's criteria. The functions of the knee joint and ankle joint were evaluated using the Hospital for Special Surgery (HSS) knee score and the scoring system of Baird and Jackson, respectively.Results The time to wound healing (17.33 ± 6.21 dvs. 22.27 ± 8.12 d;t=3.018,P=0.004) and the time to fracture healing (32.25 ± 6.02 weeks vs. 36.37 ± 7.75 weeks;t=2.623,P=0.011), and the drainage time (17.01 ± 4.66 dvs. 21.51 ± 5.23 d;t=4.012, P<0.001) in the combined treatment group were significantly shorter than those in the routine treatment group. According to Paley's criteria, the patients who achieved a score of excellent or good for fracture healing (84.6%vs. 53.8%;χ2=7.282,P=0.007) and function (92.3%vs. 66.7%;χ2=6.369,P=0.012) in the combined treatment group were significantly more than those in the routine treatment group. The scores of the HSS knee score (84.56 ± 7.42vs. 78.81 ± 5.33;t=3.391,P=0.002) and the scoring system of Baird and Jackson (85.01 ± 8.21vs. 79.21 ± 6.78;t=3.402,P=0.024) in the combined treatment group were significantly higher than those in the routine treatment group.Conclusion OralGuyu decoction and external application ofShengji-Yuhong plaster combined with Ilizarov external fixator and the accordion technique can promote recovery of the joint function, fracture healing and wound healing.
