BACKGROUND:As the epiphyseal plate has an important role in the growth and development of femur, the design of internal fixation should avoid the damage to the epiphyseal plate. Therefore, the positioning of pediatric femoral epiphyseal plate is particularly important.
OBJECTIVE:To investigate the biomechanical property of the new femur neck screw internal fixation in treatment of children femoral neck fracture.
METHODS:Twelve femurs were col ected from six fresh children cadavers provided by Dissecting Room of University of South China. After exclusion of bone disease with X-ray film, three new children femoral neck screws and three Kirschner wires with the diameter of 2.0 mm were used for fixation. The biomechanical tests were conducted to detect the axial compression and torsion stiffness.
RESULTS AND CONCLUSION:In the children femoral neck screw group, the axial compression stiffness and torsion stiffness under the torsional torque of maximum 3 N?m were (190.74±20.88) N/mm and (0.18±0.045) N?m/° respectively;(138.95±15.19) N/mm and (0.120±0.036) N?m/° respectively in the Kirschner wire group;there were significant differences in the axial compression stiffness and torsion stiffness between two groups (P<0.05). The results showed that the compressive strength and torsional capacity of the children femoral neck screw were strong than those of Kirschner wire. The experiment suggested that the femoral neck screw for children is a new type of ideal internal fixation device which consist with the anatomical features of children proximal femur and can meet the requirement of children femoral neck fracture with good biomechanical property.

Objectives To investigate the clinical and imaging features discriminating mass forming chronic pancreatitis (CP) from pancreatic carcinoma. Methods The clinical, radiologic, laboratory and pathologic profiles of eleven patients with mass forming CP were reviewed retrospectively. Results The patients with mass forming CP were predominantly older, male, and presented with obstructive jaundice or abdominal symptoms. Serum level of CA19-9 was slightly elevated, generally below 100 U/ml, which was lower than that of pancreatic carcinoma. The diagnostic accuracy of B-ultrasound for mass forming CP was only 18.2% and it could only be the screening method; the diagnostic accuracy of CT was 45.5%, and the main CT features included dilation of main pancreatic duct and the branches, as well as pancreatic pseudocysts or calcification. The findings of MRCP and EUS were irregular dilation of main pancreatic duct and common bile duct, which were similar to pancreatic carcinoma. ERCP could provide imaging characteristics of biliary and pancreatic duct, and the nature of obstruction, the stricture and dilation of biliary and pancreatic duct. When combined with CT scan, ERCP was useful for differentiation from pancreatic head cancer. According to histopathology, a few mass forming CP was autoimmune pancreatitis. Conclusions Mass forming CP is associated with clinical and radiologic features that are similar to those of pancreatic carcinoma. It is necessary to carefully evaluating clinical and imaging findings, laboratory findings and histopathological examinations.
