ObjectivesTo explore the clinical presentation, diagnosis and treatment of hemophagocytic syndrome (HLH) in children.MethodsThe clinical data from 11 hospitalized pediatric patients with HLH were collected and retrospectively analyzed from 2009 to 2013.ResultsIn 11 pediatric patients with HLH, 6 patients were Epstein-Barr virus associated-HLH, 1 patient was T-cell lymphoma associated-HLH, 2 patients had unknown reason, 2 patients had mutations in the UNC13D gene coding sequence, c.2459C>T/p.A832V (alanine to valine mutation) and c.3067C>T/p.R1023C (arginine to cysteine mutation) respectively. In 11 patients, 6 patients were improved after treatment and 5 patients were died.ConclusionsThe HLH in chil-dren lacks speciifc clinical presentation and progresses rapidly. It should be diagnosed and treated in time.

In numerous digestive reconstruction techniques after proximal gastrectomy for tumor of the gastroesophageal junction,widely used methods are esophagogastrostomy,esophagogastric tube reconstruction and jejunalinterposition reconstruction.More studies have been focused on jejunalinterposition reconstruction in recent years,from which a variety of modified reconstructions derive.In clinical practice,a flexible choice is needed according to the actual situation of patients.

Surgery alone for the adenocarcinoma of the esophagogastric junction (AEG) often gives unsatisfactory results, with a poor prognosis.At present, there is no unified therapeutic regimen specifically for AEG.Neoadjuvant therapy includes neoadjuvant radiotherapy, chemotherapy and chemoradiotherapy, but the applications and effects of them for AEG are still controversial.

SUMMARY Anklejointfractureisoneofthemostcommontypesoffracture.Therearemanyresearches on the injury mechanism,treatment principles and surgical techniques.A type of injury which combines posterior dislocation of fibula,known as the Bosworth injury,is relatively rare.In 1947,Bosworth first described this type of injury as an unusual ankle fracture dislocation with fixed posterior fracture disloca-tion of the distal part of the fibula.In this type of fracture,the proximal fibular shaft fragment locks be-hind the tibialis posterior tubercle.This rare ankle fracture variant is often not recognized in initial radio-graphs and requires a computed tomographic (CT)scan for verification.But there are already many re-ports,discussing the injury mechanism,treatment principles and surgical techniques.However,there are few reports of anterior dislocation of the fibula,caused by either injury or surgery.The mechanism of the injury is still not clear.This article reports a case of anterior dislocation of the fibula.We report a patient with left ankle open fracture (Lauge-Hansen pronation-external rotation stage Ⅲ,Gustilo ⅢA).Open reduction and internal fixation was done in the initial surgery,but ended up with poor reduction,resulting in fibula anterior dislocation,anterior dislocation of talus and tibia fibular dislocation.The fibula was dis-located anteriorly of the tibia,which rarely happened.The patient suffered severe ankle joint dysfunc-tion.The second operation took out the original internal fixation,reduced the fracture,and reset the in-ternal fixation.The function of ankle joint was improved obviously after operation.But because of the ini-tial injury and the two operations,the soft tissue around the fracture was greatly damaged.6 months after the second operation,and the fracture still not healed,so the bone graft was carried out in the third sur-gery.Two months after the third surgery,the function of the ankle was significantly better than before, but the fracture healing was poor,which needed further review.Through this case,we understand the rare type of ankle fracture with anterior dislocation of the fibula,and recognize that the timing and quality of initial surgery has a great impact on the patient’s prognosis and rehabilitation period.

The Hippocratic oath commands doctors to be the patients supreme advocate. Coupling this command with a well trained physician is the sine qua non of orthopaedic risk management. A favorable doctor and patient relationship is also essential. The occurrence of a malpractice lawsuit is more often the result of the failure to practice the art of medicine by the orthopaedist rather than a failure to apply the science of orthopaedics. The ER (emergency room) is a dangerous area. The risk of litigation in the emergency room is not directly proportional to the severity of injury. In fact, the risk of initiation of legal action is greater in cases of relatively modest disability.

We review the literature about Heterotopic Ossification (HO) and introduce its pathophysiology, classification, incidence, clinical presentation, diagnosis, prophylaxis and treatment in this article. HO is the presence of bone in soft tissue where bone normally does not exist. Mature HO has the same morphology as callus. It is considered that 3 conditions are necessary for HO: osteogenic precursor cells, inducing agents, and a permissive environment. Fever, swelling, erythema, and occasional joint tenderness appear in the early stage of HO. The most sensitive imaging modality for early detection of HO is three-phase bone scintigraphy which can also monitor the metabolic activity and degree of maturity of HO. Non-steroidal antiinflammatory drugs (NSAIDs) are the most effective for the prophylaxis of HO after the operation of hip replacement or acetabulum fracture. Surgical resection is the only treatment for patients with severe joint tenderness following HO.

Objective:To investigate the differences between emergency surgery and selective surgery treatment of ankle fractures with dislocation .Methods:In the study , 40 patients with ankle fracture and dislocation were treated and followed up from May 2013 to May 2014, and all the data were collected and analyzed .The subjects involved 29 male patients and 11 female patients .The patients were randomly separated into two groups , and the patients in group A were given surgical intervention within 6 hours af-ter injury , while those in group B were initially given close reduction and given selective operation when the soft tissue condition got better .Group A contained 13 male patients and 7 female patients with average age of 37.10;Group B consisted of 15 male and 5 female, with average age of 37.85.Results:The Baird-Jackson score was applied for assessment of the patients ’ outcomes.According to the score , the outcomes were classified into excellent , good, fair, and poor.In group A (emergency group), the outcomes were 13 (65.0%), 4 (20.0%), 3 (15.0%), and 0, respectively.In group B ( selective group), they were 11 (55.0%), 7 (35.0%), 2 (10.0%), and 0, respectively.The numbers of the patients from excellent to poor were 24 (55.0%), 11 (27.5%), 5 (12.5%), and 0, respectively. Conclusion: There is no significant difference in postoperative function between the two groups , however , early surgical intervention can benefit in accomplishing anatomical reduction much easier and shortening the time of hospitalization , which is cost-saving for the patients .

Objective To evaluate the results of operative treatment of comp ou nd acetabular fractures through single ilioinguinal approach. Methods 46 cases o f compound acetabular fractures were treated through single ilioinguinal approac h from June 1994 to October 2003 in our department. Their functional recovery an d complications were followed up. Results On the average, 40 cases were followed up for 40.4 months. All the fractures healed and no infection was found. Clinic al results were excellent and good in 33 patients, and only one patient showed s light ectopic ossification after the operation. Conclusions Acetabular fractures associated with anterior and posterior hemi-transverse fractures, most both co lumn fractures and some T shape fractures can be treated through the single ilio inguinal approach which can result in good reduction, satisfactory functional re covery, less invasive incision, and low rate of postoperative complications.

Objective To report a group of uncommon cases, and discuss t he impact of distal tibiofibular synostosis on the patients and its clinical sig nificance. Methods At a mean follow-up of 22.8 months(11 to 54 months), 14 pati ents with distal tibiofibular synostosis after ankle fracture were evaluated wit h Philips and Schwartz clinical scoring system of ankle. Results 3 patients comp lained of transient pain after strenuous activities. The others complained of no discomfort. All of them had no trouble in normal working and daily activities. The mean degree of plantar flexion was 47.9?, with 3.5?(0 to 10?)less than the normal side. The mean degree of dorsiflexion was 20?, with 8.6?(0 to 20? )less than the normal side. There were no degenerative changes in all ankles. T he mean Philips and Schwartz score was 90.8(82 to 98). The excellent rate was 71 .4%, and the excellent and good rates were 100%. Conclusion Distal tibiofibul ar synostosis after an ankle fracture usually gives rise to few symptoms and nee ds no specific treatment.

Objective To compare the outcomes of total hip replacement and minimally invasive dynamic hip screw in treating osteoporotic femoral intertrochanterie fractures.Methods Retrospectively analyze the clinical data of 56 patients with osteoporotic femoral intertrochanteric fractures who came to our hospital from July,2008-June,2012.Twenty eight cases who accepted minimally invasive dynamic hip screw were divided into the control group while 28 cases who accepted total hip replacement were divided into the experimental group.The blood loss and postoperative drainage,operative time,situation of implant loosening,the occurrence of postoperative complications and the clinical curative effect were compared between two groups.Results The differences in operative time,blood loss,and postoperative drainage flow,limited weight-bearing after operation was statistically significant between two group[(96.37 ± 20.42)min,(529.85±73.82) ml,(7.46±1.23) dvs (66.84±18.63)min,(152.79±37.35) ml,(14.32±2.62)d,t=5.653,24.117,12.542,P＜0.05].The differences in FRS score and Harris score between twogroups was not statistically significant [(27.75±3.59),(89.84±4.17) vs (26.41±3.16),(88.68±3.92),P＞ 0.05].The incidence in internal fixation loosening varied significantly with different degree of osteoporosis in the control group (66.7％vs18.8％,x2 =4.745,P ＜ 0.05) but not in the experimental group (11.1％ vs 10.0％,P＞0.05).Complication rate of the experimental group was significantly lower than the control group (3.6％vs 28.6％,x2 =4.766,P ＜ 0.05).Conclusions For the elder patients with osteoporotic femoral intertrochanteric fractures,the selection of surgical approach should be based on the patient's individual circumstances and the degree of osteoporosis.In the same time,attention should be paid to anti-osteoporosis therapy after operation.
