BACKGROUND:Conventional surgical repair can cause large traumas in patients with knee injuries, and patients often recover slowly after implant fixation, most of whom can appear to have poor recovery of knee function. OBJECTIVE: To explore the folow-up effect of arthroscopic double-steel wire clip fixation on tibial eminence avulsion fracture of anterior cruciate ligament. METHODS: A retrospective analysis was performed on the clinical data of 23 patients with tibial eminence avulsion fractures, who were given arthroscopic double-steel wire clip fixation. The patients were folowed up for 1-6 months. Short- and middle-term therapeutic effect as wel as IKDC and Lysholm scores before and after treatment were observed and analyzed. RESULTS AND CONCLUSION:The operation time was 35-65 minutes, and no complications, such as blood, nerve and anterior cruciate ligament injuries occurred. Moreover, no infection and other poor biocompatible reactions occurred after internation fixation. Al patients were folowed up for 1-6 months. The excelent and good rate was 87% at 1 month after treatment and 96% at 6 months after treatment. Al the patients had improved IKDC score and Lysholm score after treatment (P < 0.05), indicating that the knee function of patients was improved significantly.

Objective To observe the effect and safety of endoscopic retrograde cholangiopancre-atography(ERCP)in pregnant patients with acute biliary pancreatitis(ABP). Methods Twenty-four ABP patients,14 mild and 10 severe cases combined with pregnancy,were hospitalized from Januaray 2002 to Januaray 2007. Besides conventional managements,emergency endoscopic nasobiliary drainage(ENBD) without monitor of X-ray was performed in all patients to decrease the pressure in bile duct. Once the condi- tion of the patients Was stabilized and the common bile duct stone was confirmed,secondary endoscopic retro- grade biliary drainage(ERBD)with stent was performed in patients at early and midtrimester pregnancy,while secondary ERCP was employed in late pregnant patients after pregnancy termination. Results All pa-tients safely went through emergency ENBD without complication,and 4 patients with ampulla incarceration accepted sphinectomy with needle knife and stones were removed successfully. Common bile duct stone was confirmed in 15 patients and 5 of them underwent ERBD,the other 10 accepted ERCP. No patient died or needed surgical intervention,and they were all discharged with complete remission. Fetus of two patient with severe ABP did not survive. Conclusion Emergency ENBD and secondary ERCP or ERBD are safe and ef-fective in management of pregnancy patient with ABP.
