The percutaneous pinning is a simple, effective method for the treatment of displaced supracondylar fractures of the humerus in children. But there is some controversy in the number of pins used and the method of pin insertion. The cross pinning method provides more stability at the fracture site but the risk of ulnar nerve damage is higher than in lateral pinning method, The senenty-one displaced extension type supracondylar fractures were treated by closed reduction and percutaneous cross pinning from January 1991 to October 1994. Among them, the medial pin was inserted in elbow extension in twenty-eight cases and in forty- three cases the medial pin was inserted in elbow flexion. Ulnar nerve injury occured postoperatively in six cases, in which the pin was inserted with the elbow in flexion position. These results may suggest that when percutaneous cross pinning method is selected to fix the supracondylar fracture of the humerus, it would be safer to insert one or two lateral pins with the elbow in full flexion position followed by one medial pin in extension position in order to reduce the risk of loss of reduction and ulnar nerve damage.

The gross tissue specimens are a valuable aid to the teaching of pathology and anatomy. However, traditional methods for storage and handling of them are discouragingly difficult and, recently, minimal surgical resections as well as preoperative interventions make it more difficult to have instructive gross specimens. Plastination is a process of tissue preservation by impregnation with silicone polymers or epoxy resins. The process in our study involves dehydration by cryosubstitution in aceton, defatting, forced impregnation of silicon polymer in a vacuum, curing and finishing. We submitted 40 surgically resected specimens to plastination. The resulting specimens are odorless, relatively dry, durable, life-like, non-hazardous, maintenance-free, and do not deteriorate with time. Plastinated specimens are a useful adjunct to the teaching of pathology, particularly suited for use in small groups, and appropriate method of tissue preservation. They are much preferred to wet preparation and conventional pots by both students and teachers owing to their accessibility, superior illustrative powers, and comparative ease of interpretation.

We present a case of medial malleolus and deltoid ligament loss with extensive overlying soft tissue defect from crushing injury. The resultant gross medial ankle instability necessitated deltoid ligament reconstruction using a bone-patellar tendon graft.

Decreased number of the Neuropeptide-Y[NPY] immunoreactive neurons in the corpus striatum and primary motor cortex of aged rat was detected by the immunohistochemical method. The animals were categorized into control and aged group and we used 10 Sprague-Dawley rat weighing 250-300gm for control group. 10 Sprague-Dawley rat weighing over 600gm for aged group. The number of NPY-immunoreactive neurons in corpus striatum and primary motor cortex were counted under the light microscope and the following results were obtained. 1. The NPY-immunoreactive neurons were evenly distributed in corpus striatum and in the primaty motor cortex, the NPY-immunoreactive neurons were concentrated within the layer II, III and layer V, VI. The typical NPY-immunoreactive perikarya was multipolar shape. 2. Decreased number of NPY-immunoreactive neurons were detected in some areas of corpus striatum and primary mortor cortex of the aged rat. 3. Decrease of NPY-immunoreactive neurons were most prominent in the caudate-putamen and there were moderate decrease of NPY-immunoreactive neurons in the primary motor cortex, mild decrease of NPY-immunoreactive neurons in the nucleus accumbens but the NPY-immunoreactive neurons were not observed in the globus pallidus in both control and aged rat. NPY is supposed to act as a neurotransmitter of local circuit neurons in the striatum and may exert its potent vasoconstrictor effects on cerebral vessels which influences on the microcirculation of cerebral cortex and striatum. So our results seems to provide an important data on change of the function in the striatum and primary motor cortex of aged rat brain.
