Object : To treat hydrocephalus by ventriculo-peritoneal shunt operation, the correct positioning of the proximal catheter in the ventricle is very important. The purpose of this study was to develop the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle in the ventriculo-peritoneal shunt operation. Materials and Methods: The "shunt guiding kit" is made of tungsten alloy and it consists of one frame, two screws and one guider. Through the guider, the proximal shunt catheter operates by mechanically coupling the posterior burr hole to the anterior target point. Results: We have treated three hydrocephalus patients with use of the "shunt guiding kit", and achieved good location of proximal shunt catheters. Conclusion: We developed the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle, and this would be very useful for preventing ventriculo-peritoneal shunt malfunction and preventing possible brain injury during the procedures.

Objective : Percutaneous vertebroplasty is often complicated by the presence of multiple fractures or non-localizing pain in the patients with osteoporotic vertebral fractures. The purpose of this study is to estimate the value of preoperative radiologic studies in the localization of symptomatic vertebrae and to determine the factors which can influence on the clinical results. Materials and Methods : We retrospectively reviewed the clinical and radiologic data of 57 vertebrae in 30 patients underwent percutaneous vertebroplasty for osteoporotic vertebral compression fractures. Inclusion criteria was severe pain(McGill-Melzack score 3, 4 or 5) associated with the acute vertebral fractures and absence of spinal nerve root or cord compression sign. Acute symptomatic vertebral fracture was determined by the presence of signal change on MR images or increased uptake on whole body bone scan. Results : Pain improvement was obtained immediately in all patients and favorable result was sustained in 26 patients(86.7%) during the mean follow-up duration of 4.7 months(5 complete pain relief, 21 marked pain relief). Those who underwent vertebroplasty for all acute symptomatic vertebrae had significantly better clinical result than those who did not. Further vertebral collapse and eventual bursting fracture occurred in 1 vertebra which showed intradiskal leakage of bone cement and disruption of cortical endplate on postoperative CT scan. Conclusion : Preoperative MR imaging and whole body bone scan are very useful in determining the symptomatic vertebrae, especially in the patients with multiple osteoporotic vertebral fractures. To obtain favorable clinical result, the careful radiologic evaluation as well as clinical assessment is required. Control of PMMA volume seems to be the most critical point for avoiding complications.

A case of cervical cord injury with neurological deficit in patient with ankylosing spondylitis is presented. Ankylosing spondylitis causes a high incidence of spinal cord injury with a minor trauma and at that time inital treatments and combined complications are quite different from other spinal cord injuries. We discuss the treament and complications of spinal cord injury in ankylsing spondylitis with literatures review.

The germ cell tumors are classified to germinoma, immature teratoma, mature teratoma, choriocarcinoma, yolk sac tumor and embryonal carcinoma. We analzyed 10 cases of suprasellar germ cell tumors which had been treated at Yonsei University Hospital from 1980 to 1990. Results of our study were summurized as follows : Common clinical symptoms are diabetes insipidus, visual dysfunction, panhypopituitarism, etc. Therapeutic plan can be based on serum and CSF AFP and HCG level. Pretreatment and posttreatment hormonal evaluation wer performed and hormonal replacement were required in all patients. Germinoma showed good outcome but immature teratoma showed bad outcome by multisystem involvement. More advanced new chemotherapeutic and immunotherapeutic agents must be studied for this tumor.

12l patients with cervical(45 patients). thoracolumbar(76 patients) compression or mild burst fractures from January 1984 to December 1994 were studied : 98 patients were treated postural reduction with hyperextension posture and 23 patients were with postural reduction and surgical methods We compared the initial and post-reduction compression height ratio. wedge angls and kyphosis angle of compression fractures The results were not only expansion of a compressed vertebral body but also successful fusion. The neurological recovery status according to Frankei classification was also improved after postural reduction. Most of the compression fractures or stable burst fractures of the cervical. thoracolumbar spines can be restored by the postural reduction

Thermography shows the skin temperature changes in various conditions of the body. The skin temperature varies according to subcutaneous blood flow under the control of autonomic nervous system Lumbar radiculopathy due to disc herniation makes difference in the temperature of lower extremities caused by the changes in general function and autonomic functions of the nerve root. Digital infrared thermographic imaging(DITI) system has been used to diagnose radiculopathy without any hazards or discomforts and shows the pain due to LDH by objective change of temperature. This study has used DITIs of 55 control cases and 217 cases of LDH patients and analysed it statistically. In the room of temperature stable at 20℃, the temperature distribution of the lower extremities of the control cases ranged from 24.9℃ to 29.9℃. The significant minimal temperature difference between right and left lower extremities range from 0.1℃ to 0.4℃. The more distal, the greater the temperature difference was. The thermatome of L4. L5 and S1 was drawn in radiating type and spot type. The thermatome showed larger area than the sensory dermatome and sympathetic dermatome. There was significant increase or decrease of temperature in thermatome in LDH patients. In conclusion, preoperative DITI of the LDH patient can be helpful for diagnosing the level do LDH and the areas of pain.

Congenital dermal sinus(CDS) is a rare entity widely known to occur as a result of the of the failure of the neuroectoderm to separate from the cutaneous ectoderm during the process of neurulation at the third to fifth week of gestation. The lesion can occur at any level of the craniospinal axis. but are located predominantly at the lumbosacral and occipital legion CDS of thoracic region and cervical region are rare The patient with CDS presents with meningitis and/or mass effect from the associated inclusion tumor They ars usually dermoid or epidermoid cyst. Teratoma is rarely associated with CDS. We report our experience of CDS in an 11-month old boy associated with an lntramedullary dermoid tumor at the thoracic region and together we report a review of the literature.
