PURPOSE: The single-radius design of the knee implant was introduced to improve the results of total knee arthroplasty (TKA) by reducing maximum extensor forces, and it also represents more physiologic quadriceps force pattern, which could have a positive effect on knee function after TKA. We studied mid-term results of single-radius designed cruciate retaining (CR) TKA. MATERIALS AND METHODS: We analyzed the functional improvement and radiological osteolytic pattern after TKA using the single-radius Scorpio CR prosthesis. TKA was performed on 102 knees. The mean follow-up period was 73.8 months. For clinical assessment, the range of motion (ROM), Harris hip score, and functional outcome score were obtained preoperatively and at last follow-up. RESULTS: The average ROM was 100.2degrees preoperatively and 121.7degrees at last follow-up. The average knee score was 59.2 points preoperatively and 92.9 points at last follow-up. The average functional outcome score was improved from 51.9 points preoperatively to 85.4 points at last follow-up. Radiolucency was observed in four knees but all were non-progressive lesions smaller than 2 mm. CONCLUSIONS: The clinical outcome of TKA using the single-radius CR prosthesis was good during the mid-term follow-up and the incidence of osteolysis was very rare.

OBJECTIVE: To evaluate the diagnostic value of computed tomography-myelography (CTM) compared to that of magnetic resonance imaging (MRI) in patients with lumbar radiculopathy. METHODS: The study included 91 patients presenting with radicular leg pain caused by herniated nucleus pulposus or lateral recess stenosis in the lumbar spine. The degree of nerve root compression on MRI and CTM was classified into four grades. The results of each imaging modality as assessed by two different observers were compared. Visual analog scale score for pain and electromyography result were the clinical parameters used to evaluate the relationships between clinical features and nerve root compression grades on both MRI and CTM. These relationships were quantified by calculating the receiver-operating characteristic curves, and the degree of relationship was compared between MRI and CTM. RESULTS: McNemar's test revealed that the two diagnostic modalities did not show diagnostic concurrence (p<0.0001). Electromyography results did not correlate with grades on either MRI or CTM. The visual analog pain scale score results were correlated better with changes of the grades on CTM than those on MRI (p=0.0007). CONCLUSION: The present study demonstrates that CTM could better define the pathology of degenerative lumbar spine diseases with radiculopathy than MRI. CTM can be considered as a useful confirmative diagnostic tool when the exact cause of radicular pain in a patient with lumbar radiculopathy cannot be identified by using MRI. However, the invasiveness and potential complications of CTM are still considered to be pending questions to settle.

In 1961, Cornes first introduced the term multiple lymphomatous polyposis(MLP), and since then, this very raredisease has been considered as a malignant lymphoma originating in the mantle zone of gastrointestinal lymphoidtissue. MLP presents with a 0.5-2.0cm sized polypoid tumor, which affects long segments of the alimentary tractand frequently invades the mesenteric lymph nodes. It often consists of a dominant mass rather than polyps. Wedescribe three cases of endoscopically proven multiple lymphomatous polyposis, and include a review of theliterature. In differentiating multiple lymphomatous polyposis and other types of multiple polyposis in thegastrointestinal tract, the following features are helpful : the smooth surface of polyps, which is similar to agem seen during a barium examination ; the typical appearance of a gastric submucosal tumor and hypertrophiedgastric mucosal folds in UGI; the presence of enlarged lymph nodes, as seen on abdominal CT scanning.

Chlamydia trachomatis is known as a major causative microorganism in non-gonococcal urethritis(NGU) in men. We examined two kinds of specimens simultaneously, endourethral swab and urine, in each patient to determine the reliability of these two different specimens for the detection of the Chlamydia trachomatis antigen in male NGU patients using ELISA method. Tota1 273 patients entered this study were divided into two groups according to sampling order of urine and endourethral swab. In group A(141 patients), we took endourethral swab first, then first portion of voided urine was caught. In group B(132 patients), endourethral swab was performed after urine sampling. Twenty five out of 273 patients(9.2%) showed Chlamydia trachomatis antigen positive in endourethral swab sample and 1 out of 273 patients(0.4%) was positive in urine sample. There was no significant difference of antigen positive rate of endourethral swab examination between group A and group B. Our data suggest that examination of endourethral swab is more reliable method for the detection of the Chlamydia trachomatis antigen than urine examination in male NGU patient.

Comminuted proximal humeral fractures with displaced three- or four-part fragments, fracture-dislocations, and humeral head-splitting fractures are very difficult to treat. In older patients, hemiarthroplasty or reverse shoulder arthroplasty is often the indicated treatment. Arthroplasty in this patient cohort is a very technique-dependent procedure, and relies on preserving deltoid function, proper component placement and fixation, and tuberosity fixation. Although pain relief is predictable, it is often difficult to achieve functional improvement. Results depend on the patient's age, timing of the surgery, tuberosity healing, and adequate rehabilitation.

In the 88 cases of biliary disease, which was proven in Seoul Red Cross Hospital from Jan. 1980 to Dec. 1981,comparative studies were made with oral and IV cholecystocholangiographic findings and ultrasonographic findings.The resuslts were ; 1. In the 18 cases of GB stones, there are 17 cases (94.4%) of positive findings incholecysto-cholangiography with detection of stone in 7 cases (38.9%), while in sonographic study, 16 cases(88.9%) are shown positive findings with detection of stones in 11 cases (61.1%). 2. In the 17 cases of acalculouscholecystitis, the diagnostic accuracy is 88.2% in cholecystocholangiography and 64.7% in sonography. 3. In the 7cases of CBD stones, all cases are shown positive findings in cholecystocholangiography with detection of stone inonly one case (14.3%), while 6 cases (85.7%) of positive findings are shown in sonography with detection stone inall cases. 4. I.V. cholanagiography is more accurate diagnsotic procedure rather than oral GB study in the casesof poor or non-functioning GB. 5. Sonography is the choice of procedure in the diagnosis of stones, while in thecases of colecystitis, cholecystocholangiography is more useful diagnostic procedure.
