Objective The purpose of this study is to evaluate the safety and operation of a modified coaxial portals for posterior ankle arthroscopy. Methods 20 anticeptic-frozen ankle specimens were divided into 2 teams at random equally. In the first team, the original coaxial portals designed by Acevedo were established with K-wires first, then followed by modified coaxial portals. In the second team, modified coaxial portals were created at two levels, one at 1.5 cm proximal to the tip of lateral malleolus and the other at 2.5 cm to the tip. K-wires were left in place for distance measurement between them and the posterior important anatomic structures. Mimic ankle arthroscopy operation was performed on 5 fresh ankle amputations, using 2.7 mm, 30? arthroscopy with the modified coaxial portals technique. Results Results of the anatomic study show that the average distince was (22.07+2.82) mm to the small saphenous vein, (5.39+1.47) mm to flexor hallucis longus tendon, (6.27+1.84) mm to the tibial nerve in modified coaxial portals and (8.54+2.76) mm to the small saphenous, (3.62+1.37) mm to flexor hallucis longus, (4.40+1.40) mm to the tibial nerve in the original one. Only the difference of the average distance to the tibial nerve in the No.2 team has statistic significance. Flexor hallucis longus and flexor digitorum tendon were identified as the inner-safety landmarks. Neither penetration nor contact of nerve or vessel was observed. Conclusion Compared with original ankle posterior coaxial portals, the modified coaxial portals may be superior safety, easier-operated and reproducible.

Fu's subcutaneous needling (FSN) is a modern approach developed from traditional Chinese acupuncture. It could give some stimulation in the subcutaneous region that has a quick and long-lasting effect on soft tissue injuries and some of the internal medicine diseases. It is a safe approach without adverse reaction. Through analysis of the features and possible mechanism of FSN, it is believed that research on mechanism of FSN is beneficial to the development of modern medicine, especially to pain management.

Under the socialist market-oriented economic system, state-owned hospitals need to overcome many problems in their traditional management system. The authors discuss a series of issues, including the property right involved in the reform of the management system of state-owned hospitals; the relationships between nonprofit hospitals run by the government and ways of handling them; the conditions of using the corporation management structure in hospitals; the responsibilities of the government in the framework of medical services and the form in which the government supervises state-owned hospitals. Lastly, the authors put forward suggestions from the perspective of policy-making on the reform of the management system of state-owned hospitals.

Objective To analyze the CT findings of lung cystic echinococcosis with infections, and to assess the value of CT examination. Methods The CT characters of 23 cases of pathologically proved lung cystic echinococcosis were analyzed and CT findings were compared with pathology. Results All 23 cases of lung cystic echinococcosis appeared as single cystic lesions. Fifteen cases appeared in the right lung, and the other 8 in the left. The lesions located in lower lobe were more than those in the upper lobe. According to the CT examination, it could be divided into two types: (1) simple lesion (7 cases) appeared as irregular solid mass with different size, crude edge, and lobulation, and with fiber shadows in the lung field around the lesions. In 6 cases, curvilinear or spotty calcification occurred in the lesions. (2) echinococcosis as a bag (16 cases) appeared as a mass with cystic changes in lung tissue with different size and off-center cystic cavity. The lesions took the form of ball or irregular shape. The edge was crude. Around the focus, prickle-like or patchy changes were detected. Ruptured lesions showed “water snake” or “flow ribbon” signs in 4 cases. In 7 cases, calcification occurred on the cystic wall or extended into the inside contents. Conclusion CT could accurately demonstrate the location, appearance, internal structure, and adjacent situation of the cystic echinococcosis, providing valuable information for correct diagnosis and treatment.

OBJECTIVETo observe the therapeutic effects of steel plate fixation after the failure of arthrodesis of ankle by screw fixation.

METHODSFrom August 2001 to October 2011, 15 patients were with steel plate fixation after failure of arthrodesis of ankle by screw fixation. Among patients, 9 cases were males and 6 cases were females,ranging age from 40 to 65 years old with the average of 56 years old. Ten cases were in left and 5 cases were in right. Screws were removed and steel plate was fixed intraoperatively, and plaster external fixation for postoperation. Clincal effect were evaluated according to AOFAS scoring system from pain, waliking ability and aligment before and after operation, and X-ray was used to evaluate joint fusion after operation.

RESULTSAll patients were followed up, and the duration ranged from 4 months to 4 years with an average of 2 years. The incison were healed in stage I. No ankle pain,injury of blood vessel and nerve,infection and farilure of internal fixation occuerred. The AOFAS score increased from 36.86 +/- 8.32 preoperatively to 85.09 +/- 4.65 (t = -26.366, P = 0.000).

CONCLUSIONSteel plate fixation after the failure of ankle arthrodesis of screw fixation has the advantages of rigid stability, simple manipulation and high success rate, less pain, perfect recovery.
