OBJECTIVETo investigate the effcacy of the staple fixation for the treatment of hamate metacarpal joint injury.

METHODSFrom May 2009 to November 2012,16 patients with hamate metacarpal joint injury were treated with staple fixation including 10 males and 6 females with an average age of 33.6 years old ranging from 21 to 57 years. Among them, 11 cases were on the fourth or fifth metacarpal base dislocation without fractures, 5 cases were the fourth or fifth metacarpal base dislocation with avulsion fractures of the back of hamatum. Regular X-ray review was used to observe the fracture healing, joint replacement and position of staple fixation. The function of carpometacarpal joint and metacarpophalangeal joint were evaluated according to ASIA (TAM) system evaluation method.

RESULTSAll incision were healed well with no infection. All patients were followed up from 16 to 24 months with an average of (10.0 +/- 2.7) months. No dislocation recurred, the position of internal fixator was good,no broken nail and screw withdrawal were occurred. Five patients with avulsion fracture of the back of hamatum achieved bone healing. The function of carpometacarpal joint and metacarpophalangeal was excellent in 10 cases,good in 5 cases, moderate in 1 case.

CONCLUSIONThe application of the staple for the treatment of hamatometacarpal joint injury has the advantages of simple operation, small trauma, reliable fixation, early postoperative function exercise and other advantages, which is the ideal operation mode for hamatometacarpal joint injury.

OBJECTIVETo discuss the effect of surgical staging and using craft bone with vancomycin for the treatment of calcaneal fractures.

METHODSFrom January 2006 to December 2012,13 patients with open calcaneal fractures were treated including 9 males and 4 females with an average of 35.2 years old ranging from 23 to 66. All cases were emergency cases. According to Sanders classification of calcaneal fractures, 2 cases were type II, 7 cases were type III, 4 cases were type IV. According to Gustilo-Anderson soft tissue injury classification, 8 cases were type II, 2 cases were type III A, 2 cases were type III B, 1 case were type III C. Firstly a thorough debridement or VSD procedures were applied,secondly calcaneal fracture were treated with open reduction, plate fixation and bone graft complex with antibiotics. Based on clinical examination, radiographic evaluation, and American Foot and Ankle Surgery Society (AOFAS), ankle function were evaluated after operation.

RESULTSOpen wounds were headed after dressing and repairing,, lateral calcaneal wound were healed during the first period. All patients were followed up for 6 to 36 months (means 14.5 months). Fracture healing time was 14 to 20 weeks (means 16.2 weeks). Last follow-up AOFAS ankle-hindfoot score was (80.0 +/- 7.4) ranging from 55 to 95.

CONCLUSIONFor patients with open fractures, through reasonable clinical evaluation, staging operation, using bone graft with antibiotics can reduce the incidence of postoperative wound infection and promote fracture healing.

Objective To investigate the diagnostic value of double balloon endoscopy (DBE) in the elderly. Methods Clinical manifestations and endoscopic findings of 42 elderly patients (aged 60-80 years) and 73 young and middle-aged patients (aged 12-59 years) with small bowel lesions were obtained and compared. Factors influencing the diagnostic outcome of DBE in patients with small bowel bleeding were identified,and the optimal check time after the latest bleeding was determined.Results The procedures of 85.7％ (36/42) in the elderly and 79.5％(58/73) in young and middle aged were completed (P＞0.05).There was no significant difference in the procedure time between the two age groups.No severe complications were observed in the elderly group.The overall positive rate by double balloon enteroscopy examination were 71.4 ％ (30/42) and 63.0 ％ (46/73),respectively in the two groups (P＞ 0.05). Ulcer and tumor lesions were the most common findings,and diverticula and angiodysplasia were the second common findings. Longer duration of bleeding and higher number of bleeding episodes were found in the elderly with positive DBE findings than those with negative findings. Positive diagnostic rate was significantly higher when DBE was performed within 7 days than that after 7 days (90％ vs. 40％). Conclusions DBE is a safe,reliable diagnostic modality,especially in the elderly patients with small bowel bleeding in which ulcer and tumor lesions are the most common identifications.DBE is of greater benefit in patients with more bleeding episodes over a long period,and should be performed within 7 days after the last bleeding.

Objective To investigate the myocardial protective effects of“integrated strategy”with HOE-642 plus modified K/Mg on canine heart grafts.Methods Sixteen donors-recipient pairs of adult canines were divided into the“integrated strategy”group,i.e.,donor hearts were protected with HOE-642 plus K/Mg(IS,n=8)and the routine method(RM,n=8)group.Both groups un- derwent hypothermia stored for 4 h,followed by orthotopic transplantation.Cardiac heamodynamics was measured and myocardial ultrastructure and myocardial water content were evaluated.Results One of 8 animal died of aortic anastomoses leakage in each group,and the rest could wean from car- diopulmonary bypass successfully.Preservation of left ventricular contractility,as well as left ventric- ular compliance was significantly better in the IS group than in the RM group(P＜0.05),also,per- centage of myocardial water content was significantly lower in the IS group than in the RM group(P＜0.05).Myocardial ultrastructures were not damaged significantly in both groups,however,better myocardial preservation were seen in the IS group.Conclusion Both the clinically used“routine meth- od”and“integrated strategy”might provide safe donor heart preservation for 4 h,but the later scheme conferred more optimal effects with alleviating the myocardial swelling,preserving myocardial ultra- structure integrity and enhancing postischemic-reperfusion cardiac functional recovery.

Objective To know the influence of gastrointestinal decontamination (including gastric lavage and activated charcoal treatment) on prognosis of asymptomatic presentation poisoning patients.Method six hundred and twenty seven asymptomatic presentation poisoning cases through January 1999 to December 2006 were reviewed retrospectively.Duration of ED stay and intubation requiring rate were compared between the intervention group and control group (patients treated only with supportive care),as well as complications associated with gastrointestinal decontamination intervention.Results Statistic analysis reveals no difference between the intervention group and the control group in rate of intubation (6.5 % vs 5.3 %,P=0.51) and emergency care unit admission (28.1% vs 26.6%,P=0.68).Meanwhile duration of ED stay is prolonged profoundly in prevention group [ (11.2?4.7) vs (8.9?5.0),P

OBJECTIVETo explore the methods and therapeutic effects of trans-fibular anterior-lateral approach combined with external fixation in the treatment of Gustilo III distal tibiofibula fractures.

METHODSFrom 2007 to 2010,9 patients including 7 males and 2 females with the mean age of 40 years(ranging from 29 to 51 years). All patients received internal fixation of fibula after debridement on the first phase, external fixator were used to fix tibia across ankle joint, and removed after successful skin graft; The second phase tibia was used to fix through the lateral incision used in phase I. Early functional exercise was encouraged ,the union condition and functional results of the ankle joint was evealuated. The criteria of the AOFAS Foot and Ankle Surgery was used to evaluate the effects.

RESULTSAll patients were followed up,and the duration ranged for 8 to 37 months(averaged 21 months). Nine patients were achieved bony union, the average healing time was 24 weeks. No plate rupture or screw loosening was found. According to the AOFAS Foot and Ankle Surgery evaluation system, 3 cases got excellent results, 4 good cases and 2 fair.

CONCLUSIONTrans-fibular anterior-lateral approach combined with external fixation for Gustilo III distal tibiofibula fractures can receive satisfactory reset, debond ankle joint eralier and imporove the clinical effects.
