Objective To compare the results of locking intramedullar nail and Locking plate in treating proximal humerus fractures and discuss features of each instrument. Methods A total of 54 patients with fresh two-part surgical neck fracture of proximal humerus were divided into intramedullar nail fixation group(26 patients)and locking plate fixation group(128 patients).with no statistical difference upon age,gender and dominate hand involvement in two groups.At final follow-up,physical examination and X-ray films were used to evaluate fracture healing of shoulder ioint.In the meantime,VAS score,ASES score,Constant-Murley score,UCLA and SST questionnaire were used to evaluate the function of the shoulder in two groups. Results All fractures were healed basically within 8 weeks postoperative-ly.No infection or av&scular necrosis were fouml during follow-up.The incidence rate of complication in locking plate fixation group was higher than that in intramedullar nail fixation group.Both groups obtained satisfactory functional recovery of shoulder ioint.There was no statistieal difference in regard to active for-ward elevation,external rotation besides body,active height of internal rotation,Constant-Murley scores,and SST scores in both groups.The average ASES score and VAS score of locking plate fixation group was significantly better than those of intramedullar nail fixation group. Conclusions Both fixations can treat surgical neck fractures of proximal humerus well.Locking intramedullar nail causes less trauma to the patient while Locking plate has advantages in patients'final functional recovery.

Objective To evaluate the results of delayed proximal humeral fractures treated by open reduction and internal fixation. Methods From January 2005 to July 2008, 26 patients with delayed proximal humeral fractures were treated by open reduction and internal fixation. There were 11 males and 15 females. The patients ranged from sixteen to 22-81 years old, with an average age of 49.3 years. The interval from injury to operation ranged 22 to 510 days, with a mean of 88 months. There were two-part fractue in surgical neck in 12 cases, two part in lesser tubercles of in one case,two part in greater tubercles in seven cases, three part in greater tubercles in three cases, four part in 2 cases and the splitting fracture in the head of humerus in one ease.The range of motion, VAS for pain, ASES (American sboulder and elbow surgeon's form) score, Constant score, UCLA (University of California-Los Angels scoring system)score and SST(Sim-pie Shoulder Test) for function evaluation were all recorded. The results were evaluated according to sex,age, injury side, operation times and combined injury by ANOVA.The correlation analysis was performed between operative time and results. Results The average forward flexion was 137.3°±35.1°, average exter-nal rotation was 28.9°±24.1° and internal rotation was T_(10). The mean VAS score was 0.7±1.2, the mean Constant was 83.1±17.9, the mean UCLA was 28.9±6.0, the mean SST was 8.7. There were no difference re-gaming sex, age, injury side, operation time and combined injury, fracture type and complications groups. No correlation existed between operative time and results. Conclusion It is very hard to treat delayed proximal humeral fracture due to high complication and demanding experience. With appropriate surgical technique, satisfactory results can be expected by open reduction and internal fixation.

Chinese Journal of Hepatobiliary Surgery 2016;22(4):239-243
Objective To determine the optimal volume of plasma that should be used to perfuse through the portal vein (PV) to washout preservation fluid in retrograde reperfusion during liver transplantation.Methods The clinical data of S0 patients who underwent orthotopic liver transplantation (OLT) using retrograde reperfusion via the inferior vena cava (IVC) in our hospital from January 2011 to October 2013 were retrospectively analyzed.The patients were divided into two groups based on the volume of plasma infused via the PV to flush out the preservation fluid.Group 1:27 patients who received 400 ml,and Group 2:23 patients who received 1 200 ml.The preoperative and intraoperative data of the two groups were compared and analyzed.The serum concentrations of K+,Na+,Ca2+,mean arterial pressure (MAP) and pH were continuously monitored in the transplant recipients at different time points during liver transplantation.In addition,for patients in Group 2,the serum K +,Na + and Ca2 + concentrations in the samples of effluent fluid from the liver grafts were collected via the anastomotic stoma of the infrahepatic IVC and measured after infusion of 200 ml,400 ml,600 ml,800 ml,1 000 ml,or 1 200 ml of plasma.Results There were no significant differences in the preoperative and intraoperative data between the two groups.The plasma concentration of K + in Group 1 was significantly higher than that of Group 2 at 1 min after PV revascularization (T3) [(4.31 ± 0.54) mmol/L vs (3.96 ± 0.58) mmol/L,P < 0.05],while the pH was significantly lower in Group 1 than that of in Group 2 (7.26 ± 0.02 vs 7.30 ± 0.04,P < 0.05).The plasma Na + and Ca2 +concentrations,as well as the MAP,were not significantly different between the two groups at this time point.In group 2,no significant changes were observed in Ca2+ concentration in IVC blood following perfusion of 200 ml plasma.The insignificant changes in Na + after perfusion of 400 ml of plasma and for K + after 800 ml of plasma (P > 0.05).Conclusions The electrolyte concentrations,blood pressure and arterial blood pH were fairly normal after resuming flow with PV revascularization after a perfusion volume of 800 ml of plasma.This volume was the most appropriate perfusion volume,balancing its effectiveness with economy to wash out any UW solution during OLT using retrograde reperfusion.

Objective To investigate and compare the biomechanical stability between anatomical and overlapping reconstruction of the greater tuberosity in cadaveric humeral head replacement model. Methods Eight pair (16) fresh-frozen shoulder cadavers were match-paired into 2 groups. Four-part fracture model was created in all cadavers. Standardized humeral head replacement procedure was carried out in all specimens, and anatomical and overlapping reconstruction of the greater tuberosity was applied to each group respectively. Custom mounting apparatus and fixation jigs were designed for designated shoulder motion. A Binocular 3D Computer Vision metrical method was employed to measure the displacement of greater tuberosity relative to the humeral diaphysis. Results When the shoulder was external rotated to neutral position, the mean displacement of greater tuberosity in anatomical reconstruction group was (1.81?1.75) mm,while the mean displacement was (3.23?2.91) mm in overlapping group. Statistical difference was found between the 2 groups. When the glenohumeral joint was elevated to 30? and 60? forward flexion, the mean displacement of greater tuberosity in anatomical group was (4.01?5.00) mm and (5.99?6.97) mm respectively, while the mean displacement was (3.02?5.27) mm and (6.97?7.00) mm respectively in overlapping group. No statistical difference was found between the 2 groups during forward flexion measurement. Conclusion In cadaveric humeral head replacement model, anatomic greater tuberosity reconstruction shows better mechanical stability compared with overlapping reconstruction during external rotation to neutral position. This result suggests that there may be some loss in mechanical stability in overlapping fixed greater tuberosity. Even though standardized postoperative rehabilitation protocol are strictly followed, evident displacement of the greater tuberosity was detected. Postpone of the postoperative rehabilitation program after humeral head replacement for a decent period of time may benefit tuberosity healing.

Objective To evaluate the clinical value of two-hour post-dose cyclosporine (CsA) level (C 2) monitoring in renal transplantation (RTx) recipients with functional renal allograft more than one year.Methods 126 RTx recipients with functional renal allograft more than one year treated with CsA-microemulsion-based triple therapy immunosuppression were enrolled. Whole blood samples were collected 2?h after CsA administration and the CsA level was measured by fluorescence polarization immunoassay (TDx).Results C 2 levels at 3 month and 1 year following RTx were 0.830 ? 0.307 ??mol/L and 0.678 ? 0.306 ??mol/L respectively, average C 2 level between 1 to 5 years was 0.609 ? 0.195 ??mol/L,and after 5 and 10 years, C 2 levels decreased to 0.546 ? 0.163 ??mol/L and 0.547 ? 0.227 ??mol/L respectively. Adequate C 2 level in the first 5 years after RTx was correlated with improved allograft renal function and there was a significant relationship between C 2 level and CsA dose. Variation of C 2 level became greater in long-term survival RTx recipients.Conclusion In long term maintenance phase of RTx recipients, C 2 concentration was also useful in the CsA therapeutic monitoring, but the variation became greater in such patients.
