Osteoporotic fractures represent the most severe complications of osteoporosis,characterized by insidious onset,high mortality and disability rates,and a steadily increasing incidence,imposing a significant socioeconomic burden.Western medicine has advantages in diagnosis and surgical interventions,while traditional Chinese medicine excels in holistic manage-ment and the restoration of bodily equilibrium.The integration of both traditional Chinese medicine(TCM)and western medicine emerges as an effective therapeutic strategy for osteoporotic fractures.In order to propagate the concept of integrated diagnosis and treatment,foster the advancement of integrated medical techniques for osteoporotic fractures,and establish standardized and nor-mative protocols for disease prevention,diagnosis,and treatment,a consensus expert group,led by Geriatric Branch of Chinese Geriatrics Society,the Young Osteoporosis Group of Orthopedics Branch of Chinese Medical Association,Osteoporosis Group of Orthopedics Branch of Chinese Physician Association,and Osteoporosis Professional Committee of the Shanghai Society of Inte-grated Traditional Chinese and Western Medicine,was established.This group engaged in deliberations and formulated the"Ex-pert Consensus on Integrated Traditional Chinese and Western Medicine Diagnosis and Treatment of Osteoporotic Fractures"elu-cidating the concept of integrated medicine and offering recommendations in the domains of prevention,diagnosis,and treatment,with the aspiration of ameliorating the prognosis of osteoporotic fractures and enhancing the quality of life for these patients.

Distal radius fracture is one of the most common injuries of human beings, particularly in young males and elderly females. There are various classifications among which classification by author' names and the AO fracture classification system are most frequently used. Although the latter one is overall and consummate, a precise classification system with complete description of the fracture remains to be raised. Recently, with the development of wrist biomechanics and microscope anatomy, more and more studies were made to treat distal radius fracture. Good reduction and fixation are the key points for treatment. In tenns uf treatment, several options exist. Nonoperative management consists of closed replacoment and external fixation. Operative treatments includes intrafocal pinning ,non-bridging and bridging external fixation , various methods of open reduction internal fixation and hone or bone substitute transplantation. Besides, arthroscopic-assisted external fixation and artificial joint for wrist become a new hot spot. However,any single therapy could not treat all sorts of distal radius fractures. Therefore, it is better to institute individualized therapy according to different fracture characteristics of each patient in order to achieve the best curative effect. This review aims to make a conclusion about advancement in distal radius fractures, in aspects of epidemiology, classification and treatment.

OBJECTIVETo observe the effective of the injectable artificial bone combined with plate fixation for reconstructing the collapse tibial plateau fracture.

METHODSFrom June 2005 to January 2008,21 cases of collapse tibial plateau fracture of type Schatzker II, III were treated by injectable calcium sulfate bone substitute combined with supportive plate reconstruction including 16 males and 5 females with an average age of 35.3 years ranging from 27 to 62 years. The disease course was from 3 to 7 days (means 4 days). According to Schatzker classification, there were 17 cases of type II, 4 of type III. All patients preoperatively underwent radiography, CT scanning and three-dimensional reconstruction in order to accurately understand the extent of fracture and fracture collapse and the shattered fragments of the flip direction. All the fracture with collapse > 3 mm, without joint degeneration were selcected for surgical treatment. The knee joint function after fracture healing and recovery were evaluated by Lysholm scoring.

RESULTSAll patients were followed-up for from 6 months to 2.5 years (means 1.5 years). The X-ray films and features of all fractures showed anatomic reduction or near anatomic reduction, except one case of grade II severe comminuted fracture occurred a high degree of loss and platform reset ineffective after 6 months. The Lysholm scoring of knee function showed that the mean score was (88.3 +/- 5.2). The results were excellent in 12 cases,good in 7 cases, fair in 2 cases.

CONCLUSIONMinimally invasive injectable calcium sulfate bone combined with plate fixation for reconstructing the collapse tibial plateau fracture of type II, III can effectively prevent the further loss after reduction, to improve the long-term results. Minimally invasive injectable calcium sulfate as an artificial bone substitute materials has good prospects for clinical application.

OBJECTIVETo explore the mechanical behavior of lumbar spine loaded by stress and provide the mechanical basis for clinical analysis and judgement of lumbar spine fracture classification, mechanical distribution and static stress.

METHODSBy means of computer simulation method, the constructed lumbar spine three-dimensional model was introduced into three-dimensional finite element analysis by software Ansys 7.0. The lumbar spine mechanical behavior in different parts of the stress loading were calculated. Impact load is 0-8000 N. The peak value was 8000 N. The loading time is 0-40 minutes. The values of the main stress, stress distribution and the lumbar spine unit displacement in the direction of main stress were analyzed.

RESULTSThe lumbar spine model was divided into a total of 121 239 nodes, 112 491 units. It could objectively reflect the true anatomy of lumbar spine and its biomechanical behavior and obtain the end-plate images under different stress. The stress distribution on the lumbar intervertebral disc (L(3)-L(4)) under the axial, lateral flexion and extension stress, and the displacement trace of the corresponding processus articularis were analyzed.

CONCLUSIONIt is helpful to analyze the stress distribution of lumbar spine and units displacement in static stress loading in the clinical research of lumbar spine injury and the distribution of internal stress.

Glucocorticoid is a kind of steroids hormone secreted by the adrenal cortex zona fasciculate or artificially synthesized. It can mediate the synthesis and metabolism of carbohydrate, lipid and protein and has the function of inhibiting immune response and anti-inflammation, anti-toxic and anti-shock effects. However, long-term intake of corticostereoid hormone will result in bone loss, even severe osteoporosis, and increase the risk of fracture. As a result the research on the mechanisms of osteoporosis become more and more necessary. Now, according to the differences in establishment methods, there are three approaches, i. e. pellet implantation, drinking water and injection. As a result of the only partial similarity between different osteoporosis models and humans, there is a special application of each type of animal model of osteoporosis. The osteoporosis in glucocorticoid-induced model is mainly caused by modulating incretion, promoting bone absorption and inhibiting the osteoblast differentiation. In the meanwhile, compared with the other animal models, genes in mice are closer to humans, and they have many advantages in cost, gene and cell techniques. Therefore, glucocorticoid-induced mouse models of osteoporosis has a great significance in osteoporosis research. This article will review the establishment methods of glucocorticoid-induced mouse models of osteoporosis.
