1.Clinical Observation on Weight Bearing of the Tibial Fractures with Functional Below the Knee Cast
The Journal of the Korean Orthopaedic Association 1970;5(4):189-195
The early weight bearing in treatment for tibial fractures was reporded first by Gurd(1940) and in recent by Weissman(1966), Sarmiento(1967), and Brown(1969). 1. One hundred and fifty cases of fractures of the tibia treated at the Orthopedic Department f the 17 th Army Hospital during period of January 1968 to June 1970 were subjected to analysis. Of three groups, first group was applied functional below the knee cast after mannual reduction and started weight bearing on the 5 th weeks from injury, second group was treated with same method as first group except the reduction was achievd surgically, and third group was applied toe-to-groin cast after manipulation with no weight bearing until union. 2. Casting method; The toe-to-groin cast was applied on the day of injury after manipulation and functional below the knee cast was applied tightly after swelling was subsided. Supporting the leg on the table, we could obtain satisfactory alignment in all cases. Especial firm molding over the medial flare of the tibia, Patellar tendon and popliteal space was the most important step in applying this type of the cast. Finally rubber walking heel was held in place throught the tibial axis. 3. Traffic accident was the most common cause of the fractures in this series and it was 78 cases out of 150. 4. The average healing time of the first group was 15.7 weeks, of second group was 19.4 weeks, and of third group was 23.5 weeks. 5. The open and/or comminuted fractures would delay healing time, and prolonged convalescent period. 6. Though slight shortening and angulation was observed in the early weight bearing groups, the final function was excellent.

Surgery is the treatment of choice for recurrent dislocation of the patella and many proposed operations can conveniently be grouped into three headings: transposition medially of the quadriceps pull mechanism (Hauser), installment of medial checkrein, either proximal or distal to the patella (Campbell) and patellectomy (West and Sotto Hall). Two cases of the dislocation observed in the young men are reported here, in which the authors performed an operation consisting of Hauser method and in addition the medial checkrein utilizing semitendinosus tendon. The results were successful in both cases, with complete restoration of the knee function.

PURPOSE: We performed this study to assess the value of CT in the differential diagnosis of palpable neck masses in children. MATERIALS AND METHODS: We retrospectively reviewed the CT scans of the palpable neck masses in 30 children. The masses were proved histopathologically and classified into cystic, solid, and inflammatory mass and their CT findings were analyzed. RESULTS: Twelve cases were cystic masses, 4 were solid masses, and 14 were inflammatory lesions. Cystic masses included cystic lymphangiomas (n=6), branchial cleft cysts (n=3), thyroglossal duct cysts (n=2), and ranula (n=l). Cystic lymphangiomas showed insinuating appearances into adjacent structures and 4 cases occurred in the posterior cervical space. All branchial cleft cysts were round cystic masses with smooth wall and displaced the submandibular gland anteriorly and the sternocleidomastoid muscle posteriorly. Two thyroglossal duct cysts occurred centrally adjacent to the hyoid bone and 1 ranula in the submental area. Solid masses were juvenile hemangioma, pleomorphic adenoma in submandibular gland, neurilemmoma, and fibromatosis colli. Juvenile hemangioma showed well-enhancing mass with indistinct margin and the other solid masses had well-defined margin with their characteristic location. Inflammatory lesions were abscess (n=4), deep neck infections with lymphadenopathy (n=4), submandibular gland inflammation (n=3), and tuberculous lymphadenitis (n=3) and they showed strand-like enhancement in adjacent subcutaneous tissues. Tuberculous lymphadenitis had multiple lymph node enlargement with internal low attenuation areas and showed less surrounding strand-like enhancement than suppurative lymphadenopathies. CONCLUSION: Most neck masses in infants and children were of congenital or inflammatory origin. CT is useful for the evaluation of the child presenting with a neck mass, because it can differentiate various forms of neck masses and is able to reveal the relationship of the masses to the adjacent structures with their characteristic location.

PURPOSE: To evaluate the indication for intracavitary Urokinase(UK) in the treatment of Ioculated pleural effusion. MATERIALS AND METHODS: We analyzed CT and US in 31 patients who were treated with intracavitary UK in Ioculated pleural effusion. In each patient, a single chest catheter (10-12F) was insected under imaging guidance. When the amount of drainage was less than 100ml/day, UK was instilled through the catheter until less than 50ml/day was drained. On follow-up chest radiographs of more than 1 month, we classified the results of treatment into 3 groups:(1) completely effective (lung expansion, over 80%);(2) partially effective (20-80%); (3) ineffective (below 20%) group. Sonographic pattern of pleural fluid was classified into anechoic, septated, and honeycomb appearances and the thickness of parietal pleura was measured on CT. RESULTS: Sixteen patients were completely effective, nine were partially effective, and six were ineffective. patients with completely or partially effective outcome had anechoic and linear septated appearance on had less than 4mm of parietal pleural thickness on CT. Of six ineffective patients, US showed linear septated in one patient and honeycomb appearance in five patients and the thickness of parietal pleura on CT was 3 mm in one patient, 4ram in two patients, 5mm in one patient, and 6mm in two patients. CONCLUSION: UK instillation through percutaneous catheter was an effective method in the treatment of Ioculated pleural effusion. However, we found near complete reaccumulation of pleural fluid when honeycomb appearance of pleural fluid on US or more than 5mm parietal pleural thickness on CT was observed, which might suggest that we should consider the other kinds of treatment method in those patients.

PURPOSE: This study describes the CT and MR findings of mucoceles occurred in the post-operative maxillary sinuses. MATERIALS AND METHODS: CT and/or MR of 19 maxillary mucoceles in 16 patients who had been operated by CaldwelI-Luc procedure were reviewed. CT scans were performed after contrast enhancement in axial and coronal planes with 5mm thickness. Three cases were studied with a 2.0 T or 0.5 T MRI, which demonstrated multi-compartment lesions. RESULTS: The lesions were bilateral in 3 cases. Compartmentalization of the antral cavity was seen in 7 out of 19 involved sinuses. Surgical bone defect of the anterior wall was the most frequent route of extension (11 cases) and extension into the infratemporal fossa with erosion of posterolateral wall was seen in 7 lesions. In 6 cases, the lesions involved orbit. The expansile and erosive bone changes were localized in every case. In one case with multi-compartment lesion, both T1- and T2-weighted MR images showed different signal intensities in each compartment which represented different protein concentration. CONCLUSION: Post-operative maxillary mucocele showed CT findings of localized erosion and bulging most frequently at the anterior wall in which the bone windows were made during the previous surgery. Post-operative compartmentalization of maxillary antrum may cause eccentric expansion of mucocete and each compartment may show different signal intensities on MR.

Superficial gastritis has been classified as a type of chronic gastritis, since a report of Schindler in GASTRLTIS, 1947. Howev~er, Benedict reported that superficial gastritis is only acute gastritis or shows normal mucosa histologically. The com mon endopical findings of chronic superficial gastritis were adherent mucus, edema, redness. The common redness which were encounterd are patchy redness and comb-like redness(Kammrotung). We studied the relationship between the redness of superficial gastritis and acute inflammatory changes histologically. Each case of superfieial gastritis was biopsied to redening and non-redening mucosa respectively. We collected 24 cases with 48 biopsy specimens. The results are as follows: Acute inflammatory changes were found only one case in redness and none in non-redness groups. There was no difference in acute inflammatory changes in two groups. The degree of mucosal atrophy were 62.5%, 66.7% in normal mucosa, 12.5%, 16.7~% in mild atrophy, 25%, 12.5% in moderate atrophy, 0%, 4.l% in severe atrophy with respect to redness and non-redness mucosa respectively. There was no difference in degree of mucosal atrophy in two groups. Mucosal atrophies were higher in older ages above 41 years old than below 40 and with increasing age, there was increasing tendency of mucosal atrophy. In conclusion, There was no relationships between mucosal redness and acute in flammatory changes histologically and also between mucosal redness and degree of atrophy.

Twenty patients with congenital aortic stenosis excluding valvular stenosis were studied beween April 1980 and April 1984 at Seoul National University Hospital. The clinical and radiologic findings with the emphasis on the cineangiographies were analyzed separately according to the type of aortic stenosis as subaortic and supravalvular aortic stenosis. The summaries of the analysis are as follows: 1. Among the 20 cases, 12 cases were subaorticstenosis and 8 cases were supravalvular stenosis. 2. The anatomic types of subaoritc stenosis were the discrete membranous type (8 cases), the fibromuscular type (2 cases) and the tunnel type (2 cases). 3. The obstruction of subaoritic types was usually severe, and the median left ventricular to aortic systolic pressure gradient was 60mmHg, and associated cardiac defects were found in 10 cases (84%), an incidence greater than that reported in mostother large series. 4. The anatomic types of 8 cases of supravalvular aortic stenosis were mainly focal type (7cases ) and 1 case of diffuse hypoplastic type. 5. The median left ventricular to aortic systolic pressure gradient of supravalvular stenosis was 75mmHg, and associated anomalies were seen in 6 cases(75%) with 3 cases of suspected mental retardation and facial abnormalities without definite hypercalcemia. 6. For accurate diagnosis of congenital aortic stenosis, retrograde left ventricular angiograms obtainend in axial pojections are of crucial importance in demonstration of anatomic types of stenosis and associated anomalies. And supravalvular aortic injection is sometimes helpful to outline the anatomy of the valve and to evaluate the degree of aortic regurgitation.
