Objective To compare the clinical efficacy between MIPPO and IIN in treat-ment of patients with tibial fractures.Methods 100 patients with tibial fractures were divided into IIN group and MIPPO group,50 cases in each group.Surgical efficacy and incidence rate of compli-cations were compared between two groups.Results After surgery,there was no significant differ-ence of clinical efficacy between two groups,but there were significant differences of incision length,blood loss and operating time between two groups (P <0.05).The incidence rate of com-plications in IIN group was 16%,which was significantly higher than 6% in MIPPO group.Con-clusion Both MIPPO and IIN have a lot of advantages in treatment of tibial fractures,and it is beneficial for patients by correct selection of indications.

Objective To investigate the relationship between the marrow edema and general clinical index,quadriceps muscle area,and the meniscus grade of knee osteoarthritis(OA).Methods 72 patients were collected with knee OA in our hospital, underwent X-ray and routine MRI examination of knee, and the same X-ray and MRI were reviewed at 12 months later in different time point.The K-L grading, bone marrow edema score, meniscal grading and VAS score of each knee joint were evaluated.The t-test and Rank-sum test were used to compare the two groups of general data, Spearman was used to perform bivariate correlation analysis.Results The age and VAS score of bone marrow edema group at the initial follow-up were significantly lower than those without edema group(P<0.05),the degree of marrow edema was moderately correlated with age and VAS score, and was not significantly correlated with other indexes.12 months later, BMI and the area of quadriceps femoris in the group with marrow edema were different from those in the group without bone marrow edema(P<0.05), the degree of marrow edema was moderately correlated with age, quadriceps area and VAS.Conclusion The range of marrow edema was related to age, quadriceps area, BMI index and VAS score in MRI.The MRI measurement could reflect the progression of knee OA more than that of X-ray.It also revealed some factors related to the progression of knee OA.
