Clinical trials

Majority of previous classifications based on two-dimensional images to analyze these complicated 3-D fractures. Small or delicate changes in rotation and positioning can result to considerable disagreement in the interpretation of standard radiographs. Therefore, a classification system which had a better reliability and reproducibility for the fractures is warranted and helpful for orthopedic surgeons. Furthermore, CT and 3-D CT construction images with high resolution give a much clearer view of the pattern of proximal humeral fractures. Edelson proposed a new three-dimensional classification for fractures of the proximal humerus. The results concluded that it was a useful in classifying these injuries with reasonable interobserver reliability. It could be hypothesized that patients with proximal humeral fractures would benefit from this 3D classification, but there is a scarcity of application of the classification in large samples. T

Crural Compartment syndrome is a well-known sequela after femoropopliteal arterial injuries in the lower extremity, particularly when there has been a long period of ischemia,need for ligation of a major vein, or when there is severe associated soft tissue.There is conteoversy in the treatment.

Acute compartment syndrome (ACS) is defined as a clinical entity originated from trauma or other conditions, and remains challenging to diagnose and treat effectively. Threre is the controversy in diagnosing, treating ACS. It was found that there was no criterion about the ACS, and result unnecessary osteotomy. The presence of clinical assessment (5P) always means the necrosis of muscles and was the most serious or irreversible stage of ACS. Besides pressure methods, the threshold of pressure identifying ACS was also controversial.
