aration caused by varieties of violence does not catch the attention of domestic orthopedic surgeons enough in the past years.This passage is to discuss the damage mechanism,clinical treatment and prognosis evaluation of this kind of injury through the analysis of the case of Logsplitter injury.Methods Retrospective analysis 23 patients of Logsplitter injury from December 2006 to December 2014,male in 17 cases,female in 6 cases,average age (43.68±12.67) years (21-60 years).Hurt injury in 9 cases,sports injury in 1 case,falling injury in 2 cases,traffic injuries in 10 cases,crushing injury in 1 case.Open injures in 10 cases,of which the Gustilo Ⅱ type in 7 cases,Gustilo Ⅲ A type or above in 3 cases,closed injuries in 13 cases.According to the AO/OTA fracture classification,44c type in 19 cases,44b type in 3 cases,44a type in 1 case.Fibula fractures in 22 cases,19 cases of medial malleolus fracture.Results 23 patients received follow-up,with an average period was (0.91±0.26) years (0.4-2.37 years).21 cases underwent open reduction internal fixation (ORIF),2 cases underwent closed reduction external fixation and K-wire fixation.17 cases were fixed with the syndesmosis screws,among them,1 screw was used to fix 14 cases,two screws were used to fix 3 cases;the utilization rate of 3.5 mm screws is higher,at 94.1％,and all screws were entered through 3 layers of cortical;Combined with medial malleolus fracture cases were fixed with cannulated screws/K-wire internal fixation.Average healing time of the skin surrounding the ankle skin was (2.26±1.91) weeks;average healing time of fracture was (15.34±5.13) weeks;Joint pain ocurred combined with joint space narrowing after loading in 18 cases,at 78.3％;Postoperative infection,2 cases,the proportion was 8.7％;Fracture delayed union 1 case.Functional examination of the ankle joint (angle measurement method):Dorsiflexion average angle (23.9±2.21)degrees,Plantar flexion average angle (32.1 ±4.13) degrees.Average angle of introversion was (23.91 ±2.24) degrees.Hallux valgus average angle (27.6±3.81) degrees.75 points and over were got in AOFAS in 21 cases,the ratio of excellent was 91.3％.Conclusion Logsplitter injury represents a kind of important and unique ankle fracture,dislocation and the inferior tibiofibular syndesmosis separation caused by varieties of violence,accompany with potentially soft tissue injury and platford injury,according to existing treatment principle and treatment strategy summarizied by us,the clinical therapeutic effect of this damage is ideal,functional recovery is relatively satisfactory prognosis.

Objective To compare the clinical results of the ureteral reimplantation with the traditional open approach and laparcocopic pneumovesical approach. Methods A retrospective review of 108 patients who underwent ureteral reimplantation from December 2004 to October 2010 was conducted.The patients were divided into open and pneumovesical groups according to the surgical approach.Perioperative results were compared between the two groups in terms of operative time,postoperative intravenous antibiotics duration,catheterization duration,postoperative stay,average total cost and surgical cost,respectively.And the pneumovesical group was divided into two stages by time,compared the operative time of the two stages and between the later stage and the open group. Results The postoperative hospital stay of pneumovesical group was shorter than the open group (6.8 ± 1.9 d and 8.9 ± 2.9 d,P =0.002 ).For catheterization duration,the pneumovesical group was shorter than the open group as well (5.2 ± 1.2 d and 6.2 ±2.2 d,P=0.057).For the postoperative intravenous antibiotics duration,the pneumovesical group was 5.0 ± 1.3 h,the open group was 5.4 ±1.6 h (P =0.159).For the total cost,the pneumovesical group was 16 067.9 ±4 295.8 RMB,the open group was 15 617.7 ± 5 486.5 R MB (P =0.168).For the surgical cost,the pneumovesical group was 9369.4 ± 1366.6 RMB,the open group was 7397.9 ± 1797.3 RMB ( P =0.083 ).Operative duration of the pneumovesical group and open group were 3.2 ± 1.1 h and 2.3 ± 1.1 h ( P =0.003).For pneumovesical group,the mean operative durations of the two stages were 3.6 h and 2.8 h (P =0.286).And the later stage of pneumovesical group was a little longer than the open group,but no significant difference ( P =0.234 ).No major complication was found in the 2 groups during the operative time and the postoperative hospital stay.Twenty-four patients (38 ureters) of the pneumovesical group were followed up with micturating cystourethrography ( MCU),ureterovesical reflux recurred in 3 patients.Two patients changed from grade Ⅲ to grade Ⅰ and 1 patient changed from grade Ⅴ to grade Ⅲ after the surgery.Five patients (9 ureters) of the open group were followed up,1 patient found bladder diverticulum; 1 patient found ureteral stricture 6 months after the surgery and got improved after secondary ureteral relimplantation surgery. Conclusions The pneumovesical approach is shorter than the open group in postoperative hospital stay and catheterization reserved duration.The pneumovesical approach is a safe and effective option for ureteral reimplantation.

Surgery management is key to surgical quality control. The authors presented the IT system design for surgery anesthesia of the children′s hospital of Fudan University, featuring all-process information support by means of IT development and process reengineering. Such a process comprises perioperative patient handover, medication, surgical safety check, and intraoperative care. This surgery anesthesia system development has interconnected hospital information systems within and beyond operation rooms in terms of informationization. It proves that the system can effectively enhance safety and convenience of surgery related works and supervision, reducing error exposure of surgical operations and ensuring patient safety.
