China Journal of Orthopaedics and Traumatology 2015;28(6):567-571
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.

Methods: Totally 70 qualified rats were selected and randomly divided into seven groups with 10 ones in each, and the rats were with intragastric administra-tion respectively by practolol oral liquid (20,10 and 5 ml·kg-1 , respectively diluted 20 ml, 10 ml and 5 ml to 20 ml liquid with dis-tilled water), furosemide tablets suspension (0. 033 5 mg·ml-1), Qiliqiangxin capsule suspension(0. 03 g·ml-1) and distilled wa-ter with the same voulme( model) . The rats were placed in metabolism cages. After the administration, the urine volume was recorded every 1 h for 5 hours, the total volume of urine was collected during the 5 h, and the concentration of Na+, K+ and Cl- in the urine was measured. Results:Compared with that in the blank group, the urine volume in 2 h, 3 h and 5 h after the administration in the model group was significantly increased(P<0. 01), the total urine volume was also increased significantly(P<0. 01), the K+ con-centration was significantly reduced in the urine(P<0. 05), and there was an increasing trend of Na+ and Cl- concentration in the u-rine, which indicated that the water load model was made successfully. Compared with the model group, furosemide could significantly increase the urine volume in 1 h, 2 h, 3 h, 4 h and 5 h after the administration, and the total urine volume was increased as well ( P<0. 01). Qiliqiangxin capsule group could significantly increase the K+ concentration in the urine(P<0. 05), and furosemide could significantly reduce the K+ concentration in the urine (P<0. 05). High-dose practolol oral liquid could significantly increase the urine volume in 5 h after the administration and the Na+ and Cl- concentration(P<0. 01), mid-dose practolol oral liquid could significantly increase the urine volume in 3 h and 5 h after the administration and the total urine volume (P<0. 05), and improve the Cl- concen-tration in the urine (P<0. 05), and the Na+ and Cl- concentration in low-dose practolol oral liquid group was decreased significantly (P<0. 01). Compared with Qiliqiangxin capsule group, the high, medium and low-dose practolol oral liquid showed no significant in-fluence on the urine volume(P>0. 05), high-dose practolol oral liquid could significantly increase the Na+ concentration in the urine (P<0. 01), medium and low-dose practolol oral liquid could significantly increase the Na+ concentration in the urine(P<0. 05), low-dose practolol oral liquid could significantly reduce the K+ concentration(P<0. 01), high and medium-dose practolol oral liquid could significantly increase the Cl- concentration in the urine (P<0. 01), and low-dose practolol oral liquid could significantly reduce the Cl- concentration in the urine (P<0. 01) . Compared with the high-dose practolol oral liquid group, the influences of medium and low-dose practolol oral liquid showed no significant difference in the urine volumes(P>0. 05), however, the total urine volume could significantly increase(P<0. 01), and the medium and low-dose practolol oral liquid could significantly reduce the Na+ and Cl- con-centration in the urine(P<0. 01). Conclusion:Practolol oral liquid has significant diuretic effect in a dose-dependent manner.
