Abstract: ［Abstract］ Objective〖HTSS〗〓To analyze the effect of three different treatment methods on the prognosis of epiphyseal osteomyelitis.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Infans with epiphyseal osteomyelitis were selected and divided into three groups according to the treatment methods: group A underwent arthrotomy and drill,and group B underwent arthrotomy. Group C did not undergo surgery treatment group as a control group. At the time of followup, 21 cases remained in each group. The shoulder joint activity(n=8), hip joint activity(n=7) and knee joint activity(n=6) as well as hospitalization and extubation time were compared before and after treatment. 
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Six months after treatment, the range of shoulder joint abduction, flexion and extension in group A and group B, and the range of shoulder joint abduction and extension in group C were increased significantly compared with that before treatment(P＜005). Six months after treatment, the range of shoulder joint abduction, flexion and extension in group A and group B were increased compared with that in group C, and the difference was statistically significant(P＜005). Six months after treatment, the range of shoulder joint abduction, flexion and extension in group A was higher than that in group B(P＜005). The flexion, abduction and adduction of the hip joint in group A and B were significantly higher than those in group C(P＜005), and the flexion and abduction of the hip joint in group A and B were significantly higher than those in group C(P＜005). After 6 months of treatment, the knee joint activity in three groups was significantly higher than that before treatment(P＜005), but after 6 months of treatment, there was no statistical difference in knee joint activity among the three groups. Learning significance(P＞005), the hospitalization time of group A and B was less than that of group C, group A was less than that of group B, and the extubation time of group A was less than that of group B, the difference was statistically significant(P＜005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Arthrotomy and drilling is effective in restoring shoulder joint(abduction, flexion and extension), hip joint (flexion, abduction and adduction) and knee joint flexion and extension, and shorter hospitalization and extubation time can reduce the disability rate of the disease and improve the quality of life of infan after operation.
