Shoulder surgery has rapidly grown into an independent branch of o rthopedics in the developed countries, but not in China, for only several large -scale Chinese hospitals have set up an independent department of shoulder surg ery. Advancement of arthroscopy and increasing application of displacement of ar tificial humeral head have enriched the treatment methods of shoulder problems s o that many of the previous contradictions can be resolved through surgery. This issue of Chinese Journal of Orthopaedic Trauma(CJOT) introduces some procedures and experience of the shoulder surgery, including operative managements of shou lder dislocation, fracture of shoulder blade, acromion impingement syndrome and shoulder instability. Surgeons should achieve as much as possible minimal invasi on and optimal functional recovery of the shoulder as long as they do not dramat ically increase the expenses of the patients.

As everyone knows, foot and ankle play a decisive role in human activities. In the recent ten years, management of lesions of foot and ankle has drawn increasing attention and interest of orthopedic scholars so that great progress has been made in this field, but there have still been many controversial issues. This review gives a brief introduction of the most up to date development and problems in the research of foot and ankle fractures, and also suggests some basic principles in treating such fractures.

The techniques and concepts in the field of orthopaedic trauma have been changed in these years by new ideas of osteosynthesis, minimal invasive surgery (MIS), computer assisted orthopaedic surgery (CAOS) and evidence based medicine (EBM). This paper briefly introduces the development trend in orthopaedic trauma through discussion of the papers exchanged in the 2nd Congress of Chinese Orthopaedic Trauma Association.

This issue features papers concerning intra articular fractures that covers surgical managements of fractures of tibial plateau at lower limbs, patella, calcaneus, glenoid cavity at upper limbs, Pilon fracture and Barton fracture. Fracture displacement, articular step off and injury of soft issue that are often associated with intra articular fractures, especially those caused by high energy, make the treatment all the more difficult. The key points for a successful treatment are accurate judgment of the severity of the injury, proper timing of the operation, application of minimally invasive skills, possibly maximum anatomic reduction and alignment of the fracture and maximum functional recovery. The author emphasizes that treatment of intra articular fractures should be individualized.

Objective To analyze the factors influencing the total cost of hospitalization after internal fixation of intertrochanteric fracture.Methods Enrolled in this study were 142 patients with intertrochanteric fracture who had been treated at our department between March 2013 and August 2014.They were 54 men and 88 women,aged from 24 to 95 years (average 69.8 years).Intramedullary fixation was adopted in 135 cases while extramedullary fixation in 7.By AO classification,32 cases were type A 1,75 type A2 and 35 type A3.We analyzed their demographic data,fracture-associated factors,bleeding-associated factors and surgery-associated factors.For univariate analysis,the independent sample t test was performed between 2 groups.One-Way ANOVA analysis was performed among several groups.For multivariate analysis,multivariate linear regression analysis was performed.P ＜ 0.05 was regarded as statistically significant.Results The independent sample test revealed that the total cost of hospitalization for those with preoperative deep venous thrombosis (6.9 ± 1.0 × 105 (￥)) was significantly higher than for those without (5.0 ± 0.8 × 105 (￥)) and the total cost for those undergoing intramedullary fixation (5.5 ± 1.2 × 105 (￥)) was significantly higher than for those undergoing extramedullary fixation (4.4 ±0.7 × 105 (￥)) (P ＜ 0.05).The multiple linear regression analyses showed that preoperative deep venous thrombosis (t =11.750,P ＜ 0.001),perioperative transfusion (t =2.803,P =0.006),hospital stay (t =5.949,P ＜ 0.001) and intraoperative blood loss (t =2.885,P =0.005) were the independent factors influencing the total cost of hospitalization.Conclusions Preoperative deep venous thrombosis,perioperative transfusion,intraoperative blood loss,and hospital stay may influence the total cost of hospitalization for patients undergoing internal fixation of intertrochanteric fracture.More attention should be paid to control of the total cost of hospitalization in addition to ensuring the perioperative life safety.

Objective To study middle-and-long-term results of the conservative management of the supination-eversion fractures of ankle. Methods A retrospective study was done for the 43 patients with supination-eversion fracture of ankle who were treated from February 1999 to August 2004 in our department, and followed up. Five patients belonged to stage Ⅰ , 10 to stage Ⅱ , none to stage Ⅲ and 28 to stage Ⅳ . The average duration of follow-up was 69 months (16 to 84 months). Results The middle-and-long-term results were graded according to the Ankle Hindfoot Clinical Rating System of the American Orthopaedic Foot & Ankle Society(AOFAS). Of the stageⅠ patients, five got satisfactory results. Of the stage Ⅱ patients, nine got satisfactory results and one unsatisfactory. Of the stage Ⅳ patients, 26 got satisfactory results and two unsatisfactory. Conclusions The middle-and-long-term follow-ups show that most of the supination-eversion fractures of ankle can be treated conservatively with a satisfactory result. Surgical treatment should be indicated for those whose conservative management cannot reach satisfactory results.

The 2002National Annual Meeting org anized by the newly founded Chinese Orthopedic Trauma Association was held in Shenzhen in J une,with attendance of 180surgeons.Leaders of Chinese Orthopedic Society and many senior professors from the o rthopedic field also attended the me eting.The major topics of this 3-day meeting were“pelvic &acetabular fractures”and“open fractures”.5orthopedic trauma experts coming from Germany and US were invited to give pr esentations at the first day symposium,with the topics about radiologic al diagnosis,surgical approach and su rgical techniques of pelvic &acetab ular fractures.Precious experiences were exchanged in trauma resuscitation,management of open fractures and man agement of infection of bone and join t.225articles were received for this m eeting,with the contents covering e very part of the skeletal system.Clinically,the treatments reported at the meeting involved modern orthopedic surgical techniques and experiences in non -operative management.As for the basic research,application of tissue e ngineering in the orthopedic field w as discussed.45articles selected for oral presentation covered the management of pelvic &acetabular fractur es,choice of internal or external fixation in treatment of proximal femoral fractures,soft tissue management i n bone and joint infections,and clinical tria ls in the treatment of scapular fractures,proximal humeral fractures,d istal radial fractures and calcaneal fractures.The articles received also revealed that the methods adopted in clinical research should be improved and standardized in China so as to promote better natio nal comparison and exchange.[

Objective To assess the methods used to analyze the clinical outcomes in recent 180c linical reports in orthopaedic trauma in Chi na.Methods Statistical analysis was done with t he collection of the papers of2002Symposium of Chinese Orthopedi c Trauma Association in the aspects o f their research scope,object,case number,fracture classification,c riterion of follow -up and application of statistics.Results Of the total 225papers received by the symposium,180were clinical reports which reported more than ten thousand cases.The s cope of reports was wide and included majo r current methods of fracture treatm ent.The papers with statistical analysis were only 6.1%.Fracture classifica tions and criteria of follow up were v aried without a standard.No prospec tive report was found.Conclusion Current methods in clinical study on orthopaedic trauma should be improv ed.[
