Objective To analyze the cause and treatment effect of pelvis obliquity accompanied with the gluteal muscle contracture. Methods 84 cases of gluteal muscle contracture with pelvis obliquity and their pelvis obliquity direction were examined. During surgery it was emphasized that release of the glutaeus minimus and glutaeus medius muscle contracture must be complete in order to expect correction of pelvis obliquity. Results Among the 84 cases of gluteal contracture with the pelvis obliquity, 76(90％ ) cases had gluteal muscle contracture of the longer limp. Follow-up had been done in 68 cases for 2.6 years. The pelvis obliquity disappeared completely in 63 of the 68 cases. Among the 63 cases, 61 cases underwent operation once while 2 cases needed revision operation. 3 of 68 cases were corrected partly. The other two cases had unstability in steps as a result of poor function of the gluteal abductors. Conclusion The main cause of the pelvis obliquity is contracture of the glutaeus minimus and medius muscles. The glutaeus minimus muscle contracture is an important factor that cause the pelvis obliquity in gluteal muscle contracture and should be released completely by surgery.

OBJECTIVE:To provide references for the application and management of anti-infectives.METHODS:Data on sale volume,DDDs etc.of anti-infection drugs in6hospitals of Guang'an city from2001to2004were statistically analyzed.RESULTS:The DDDs of oral lomefloxacin dominated the first or2nd places for the4years;The DDDs rank orders of isoniazid and rifampin were No.4and No.5respectively in the4years;The DDDs of penicillin for injection dominated the first place on the injectable preparation lists(2001～2003);The latecomer levofloxacin assumed the tendency of surpassing the early starters not only in sale volume but also the DDDs.CONCLUSION:The proportion for anti-infectives in sales volume to the sum total drug consumption of the above mentioned area were close to those of the other medical institutions in southwest area,there are less new drug varieties and the grade of drugs used in the area was low.
