Objective To explore the operation approaches and therapeutic efficacy of repairing traumatic defect of skull with self-skull particles. Methods The authors retrospectively analyzed 36 cases of traumatic defect of skull repaired with self-skull particles. Results The operations on 36 cases were all successful at one time and healing were appeared in all of the 29 cases follow up surveyed 3 months later. Conclusion Repairing defect of skull with self-skull particles is simple at operation as well as feasible in the treatment of traumatic and depressed skull fracture.

Many authors agree that preliminary traction prior to closed or open reduction for congenital dislocation of the hip is helpful. Different ways of traction have been used and each of them has its own advantages and disadvantages. One of the problems in the very young child is the difficulty in maintaining a suitable traction that is biomechanically effective. We found that using a rocker bed made the traction more "user friendly" for the child, the parent and the doctors.

Objective To discuss the application of autologous skull flap i n the repair of skull defect. Methods The bone flap in decompressive crani otomy was embedded subcutaneously and 3 months later replaced in the original si te. Results The effect of repairing skull defect is good without rejection and biological reaction. Conclusion Autologous skull flap is reliable and economical material in repairing skull defect without any rejection reaction.

Changes in the facial skull of 74 patients with untimely synostosis of craniocerebral sutures and pathologic shape of the cerebral skull are characterized. All the patients presented with shortened base of the skull, gross deformations of the facial skull. Certain regularities in the formation of these defects were distinguished.

Two cases in which cervical spine overdistraction occurred with the use of skull traction are described. A summary of the clinical presentations and definitive treatment together with some bibliographic references are discussed. Finally, suggestions regarding how to avoid overdistraction when using skull traction are given.

Abstract The skull, mandible, and five pairs of long bones from the skeletons of 125 muskrats were weighed and measured. Each bone of the pairs of long bones was weighed and measured separately. Thirteen dimensions of the skull were determined. The long bones are slightly less variable in length than the skull dimensions. There is a rather wide range of variation in the thirteen dimensions of the skull, with the length and breadth of the skull less variable than the lengths of the long bones. The coefficients of correlation show that the weight of the skull is a good index to the weights of the long bones. The skull length has likewise high correlations with the lengths of the long bones and the longitudinal dimensions of the skull, with the exception of the palatine slits. The transverse diameters are not significantly correlated with the skull length. The long bones are asymmetrical in weight and length. They are longer more frequently on the left side and all except the tibia are heavier more frequently on the left side.

Objective:Investigate the mechanism of blood spinal cord barrier disruption after spinal cord injury.Method:Thirty five male adult Wistar rats(300～350g) were randomly assigned to this study,there were one control group and six spinal cord injury groups(acording to the time of post injury,4h,6h,12h,24h,48h and 72h).Each group contained 5 rats and New York University (NYU) Spinal Cord Injury Model was utilized to create the spinal cord injury.The immunoexpressior changes of immunglobularprotein G(IgG),c fragment of complement3 (C3c) in different time after spinal cord injury were evaluated utilizing immunohistochemistry method.Result:After spinal cord injury, there was a marked chang in the immunoexpressior of IgG and C3c in the impact site, near the impact site and spinal cord microvascular.Conclusion:After spinal cord injury,IgG and C3c may be important factors of barrier disruption and related to neuron secondary injury.

Objective To investigate the expression changes of CD44 in spinal cord in 3d,7d and 14d following hemisection of spinal cord injury(hSCI).Furthermore,to explore the relationships of CD44 and spinal cord injury.Besides,to offer the morphological datum for the research concerning the spinal cord repair.Methods 20 adult healthy Sprague-Dawley rats were randomly divided into sham-operated control group and day3,day7,day14 spinal cord injury groups.The spinal cords were hemisected between T9 and T10.The spinal cord of every rat was taken out from the rostral and caudal segments of lesioned areas.Then the tissue blocks were made into 25μm frozen sections and the immunohistochemistry ABC method was performed on these sections.We respectively observe and count the number of CD44 positive cells in spinal cord for all groups,and the average OD(optical density) value of immunoreactant were detected with computer image analysis technique.Results CD44 positive products were mainly distributed in extacellular matrix and neurons and neuroglial cells in spinal cord for the control group.The number of CD44 positive cells and its OD value of rostral or caudal part of injury site for the three spinal cord injury groups were all increased(P0.05).Conclusion The increased-expression CD44 may mutually play inhibitory effect on axon regeneration following SCI.
