OBJECTIVETo explore clinical outcomes of talus neck fracture treated with mini-plate internal fixation through dual-incision approaches.
METHODSFrom August 2010 to February 2013,18 patients with closed talus neck fractures were treated (10 males and 8 females, aged from 31 to 66 years old with an average of 38.2 years old) with mini-plate internal fixation through dual-incision approaches. According to Hawkins classification, 12 cases were type II and 6 cases were type III. All cases were evaluated with X-ray and 3D CT scan preoperatively to define type and comminuted degree of fractures. Mini-plate fixation with dual-incision approaches was performed after swelling was resolved. X-ray films were taken during following up regularly. Functional evaluation was carried out according to Visual Analogue Scale (VAS), the ankle and hind-foot score of American Orthopedic Foot and Ankle Society (AOFAS). Complications were also recorded.
RESULTSSixteen patients were followed up with an average time of 22.6 months (ranged, 17 to 46 months). No wound infection, skin and flap necrosis or implant failure were found. Traumatic arthritis in subtalarjoint was found in 1 patient. Preoperative VAS (5.94±1.12) was decreased to postoperative (1.06±1.06) (t=27.13, P<0.05). The average AOFAS score was 88.7510.19 at the latest following up; and 11 cases obtained excellent results, 3 good and 2 moderate.
CONCLUSIONMini-plate fixation with dual-incision approaches for talus neck fracture especially for talus neck comminuted fracture, an effective method, could obtain stable fixation, decrease complications.

Objectives To explore the influence of standardized treatment and technical flow improvement on the diagnosis and treatment of congenital diaphragmatic hernia (CDH) after prenatal diagnosis. Methods The clinical data of neonates diagnosed with CDH who were hospitalized in neonatal intensive care unit from January 2005 to August 2016 was analyzed retrospectively. Based on the start time of standardized treatment implementation, 93 cases of CDH hospitalized from January 2010 to August 2016 were divided into the intervention group while 15 cases of CDH hospitalized from January 2005 to December 2009 were divided into the control group. The survival rate and complications of clinical outcomes between two groups were compared. Results There was no significant difference in sex, gestational age, birth weight, Apgar score, and CDH position between two groups (P >0.05). The total survival rate was 81.7% in the intervention group and 53.3% in the control group, and there was statistical difference (P<0.05). The difference of mechanical ventilation mode and pneumothorax rate between two groups also had statistical difference (P >0.05). The median operation time in the control group was 4.5 h and the intervention group was 49.5 h. The postoperative survival rate was 61.5% in the control group and 90.5% in the intervention group, and the differences between two groups were significant (P >0.05). The first blood gas analysis of deaths cases in both groups showed that there were significant differences in pH and PCO2 values (P >0.05). Conclusions Optimization of the clinical management during perioperative period can improve the survival rate of CDH and reduce complications. However, the dead cases in the intervention group had more severe pulmonary hypoplasia.
