Treatment of open tibial shaft fracture is difficult, especially when there are severe soft tissue damage. Various complications are noted. The aims of treatment for the open fractures are to promote primary wound healing and union of the fractured bone. We have employed external skeletal fixation devices those are Hoffmann apparatus and pin & resin external fixator for the treatment of 34 cases of open tibial shaft fractures from March, 1981 to May, 1984. Each fixation method was divided into two type, one-plane bilateral frame (180' frame) and two-plane bilateral frame(120') Following results were obtained. 1. Open tibial shaft fracture was most commonly occured in age of high activity of male. 2. External fixation was very useful as a primary treatment method in open tibial shaft fracture. 3. The most common complication was pin tract infection. 4. Mean duration of fixation was 12.6 weeks. After removal of extemal fixation, 8 cases of delayed or nonunion were noted. In addition to bone graft, secondary open reduction and internal fixation with plate and screws (7 cases), only bone graft (1 case) were carried out. Good results were obtained. 5. There was no significant difference in bone union time between 180' frame and 120' frame. The complications were more frequently occured in 120' frame than in 180' frame.

Urachal carcinoma is an uncommon neoplasm associated with a poor prognosis. We have encountered two another cases of urachal adenocarcinoma recently 5 years after our first report. The common sign of urachal cancer was painless hematuria. We diagnosed the specific site of origin preoperatively by means of computerized tomography. One patient was performed partial cystectomy and another was total cystectomy with double barrel ureterocutaneostomy. A brief review of the literature of urachal adenocarcinoma was also made.

Angiographic procedures and their applications maybe divided into following roups: I) procedures used to increased blood folw, as the angioplasty, II) procedures used to decreased blood flow, as the embolization and local infusion of vasoconstrictors and III) miscellaneous procedures. Transcatheter vessel occlusion was first performed in 1930 by Brook to occlude the carotid cavernous fistula by embolization of the surgically exposed carotid artery with muscle marked with a sliver clip injected directly into the internal carotid artery. Autologous clot, first used by Doppman(1968) to occlude a spinal arteriovenous malformation was quickly adopted use in traumatic hemorrhage with pelvic fracture, nonoperable aneurysm, gastrointerstinal hemorrhage and diagnosis and treatment of the tumors. In Kores, there have been several reports of transcatheter vessel occlusion after Han(1978) made a first report in the radiology part. In orthopedics part of Korea, Kim(1981) and Yoo(1982) reported the cases of surgical treatments of arteriovenous malformation without embolization. Also, in Korea, there has been no report of transcather embolizations of vascular diseases of the extremities, such as huge arterial aneurysm and dilated varicose vein. We reported the 4 cases who were treated at the Chonbuk National University Hospital between January 1987 and April 1988. Transcatheter vessel occlusion have such advantages : 1. The vascular status of the mass can be recognized prior to operation, such as biopsy. 2. Since the bleeding can be reduce, the operation can be performed easily. 3. Nonoperable huge arterial aneurysm could sometimes be treated only with transcatheter vessel occlusion adequately. 4. It can make a differential diagnosis with other vascular anomaly easy.

Nine patients of clinically definite multiple sclerosis (MS) were examined by magnetic resonance imaging (MRI) at 1.0T. The MS plaques were seen in the brain and spinal cord in eight and three patients. respectively. The frequent sites of MS plaques were periventricular white matter, brain stem, and cervical cord. The shape of most brain MS plaques was round or finger-like configuration. The MS plaques showed high signal intensity on R2 weighted images and low or iso signal intensity on T1 weighted images in all nine cases. Contrast enhancement was seen in 4 cases. Mild brain atrophy was noted in 2 cases and mass effect in 1 case. The sites of cord MS plaques in three patients were C2-C4, C2-C5, and C4-C6 levels respectively. The cord MS plaques showed high signal intensity on T2 weighted image and contrast enhancement on Gd-DTPA enhanced T1 weighted images in all 3cases with mild cord expansion in 2 cases. In conclusion, MRI is a useful diagnostic tool in evaluationg the MS plaques involving central nervous system.

Synovial chondromatosis is a rare monoarticular disorder which often involves the knee, hip and the elbow but the shoulders are less frequently affected. The diagnosis depends on the important radiographic and operative findings as well as histopathological criteria. We have experienced the synovial chondromatosis developed in the left shoulder of a 37 year-old male who was diagnosed by CT scan, axillary angiography and microscopic findings and treated at Chonbuk National University Hospital.

Simulated three-dimensional (3D) imaging represents reformation of conventional sectional imaging data into a series of images that closely resemble the original studied structure. We tried to make 3D mucosal surface images of the sinonasal cavities, pharynx and larynx, and evaluated the feature of normal anatomy in 28 subjects. In the sinonasal cavities, 3D imaging was capable of demonstrating the inner wall of paranasal sinuses and its openings, and general status status of the nasal cavity. In the nasal cavity. In the nasopharynx, 3D imaging provided an easy concept of sectional images as 3D picture and displayed anatomic subsites and lesions comparable to that in fiberscope. In addition, 3D imaging had advantages in overcoming the technical limitations in fiberscope. In the larynx and hypopharynx, 3D imaging gave a 3D concept of the laryngeal structures and presented additive information not seen in axial iamges thus enabling access to regions beyond the scope of fiberscope. In conclusion, 3D imaging allows an easy conceptualization of transaxial CT images in complex anatomic areas and provides additional in formations undetectable in transaxial CT. We believe that the spaces of the sinonasal cavities, pharynx and larynx would be a new field of application of 3D image.

Nevus lipomatosus cutaneous superficialis is a very rare skin disease, which usually is present at birth. The lesion shows groups of asymptomatic soft papules or nodules, which have a smooth or folded surface and are skin colored or yellowish. The area of predilection is the pelvic girdle (especially the buttock and sacrococcygeal areas). Microscopically, nevus lipomatosus cutaneous superficialis reveals groups of etopic fat cell nests within the dermis. Only one case was reported in Korea(1969). The authors observed a case of typical nevus lipomatosus cutaneous superficialis. The patient was 19 year-old male, who ha,ve had asymptomatic soft papules and nodules on the buttock, lower back and scalp since 14 years of his age. Routine laboratory findings were within normal limit. Histopathological findings showed etopic fat cell nests within mid and lower dermis (Fig. 3) Diagnosis was confirmed by clinical and histopathological findings. Litercature was briefly reviewed for the discussion.

The term "Milk of calcium" has been borrowed from a somewhat similar condition encountered in the gallbladder. The coexistence of stone in a caliceal diverticulum is well known but milk-of-calcium is unusual in this structure. Recently we experienced a case of milk-of-calcium in a pyelocaliceal diverticulum in a 44 year old man, so we report this case with a brief review of the literature.
