BACKGROUND: This study investigated and evaluated the clinical outcomes of intra-articular lesions of traumatic anterior shoulder dislocation (TASD) associated with greater tuberosity (GT) fracture of the humerus. METHODS: Subjects included 20 patients who were surgically or non-surgically treated for GT fracture of the humeurs with TASD, and followed-up for at least 2 years. The mean follow-up period was 54.1 months (range, 24–105 months). Of the 20 patients, 12 were treated surgically. Intra-articular lesions were identified randomly on magnetic resonance imaging scans (repeated thrice) by experienced radiologists and orthopedic surgeons. The accompanying intra-articular lesions were left untreated. Clinical outcomes were evaluated by Simple Shoulder Test (SST) and Western Ontario Shoulder Instability index (WOSI) at the last follow-up. RESULTS: Intra-articular lesions were identified in 19 patients: 7 Bankart lesions, 15 humeral avulsion of the glenohumeral ligament lesions, 3 glenoid avulsion of the glenohumeral ligament lesion, and 6 inferior capsular tears. Two or more intra-articular lesions were identified in 6 patients. The mean SST score was 10.9 and the mean WOSI score was 449.3 at the last follow-up. CONCLUSIONS: For GT fracture of the humerus with TASD, a high frequency of diverse intra-articular lesions was identified. There were no incidence of recurrent shoulder dislocations, and good clinical outcomes were obtained without treatment of the intra-articular lesions. We thereby comprehend that although intra-articular lesions may occur in TASD associated with GT fracture of the humeurs, merely treating the GT fracture of the humerus is sufficient.

Tibia valga has been described as a consequence of non-displaced fractures of the proximal metaphysis of the tibia in children. There has been considerable speculation about the cause of this deformity. Four cases of estabilished valgus deformity following injury to the proximal tibia metaphysis in children are presented. In one case of them, it was showed that an infolding of a portion of the periosteum of the tibiain medial opening of this fracture. It was treated by surgical clearence of the infolding periosteum and varus osteotomy with slight over-correction and partial fibulectomy. The recurrence of valgus deformity was absent during post operative one year. In another case, roentgenogram showed an asymmetrical growth arrest line of the pmximal tibia. The presence of asymmetrical growth arrest lines in the pmximal metaphysis of the tibia demonstrates that the valgus deformity in this patient was caused by overgrowth of the medial portion of the proximal tibial epiphyseal plate. In the remainder, we observed the deformity developed without any specific cause.

PURPOSE: To measure the size of normal corpus callosum in each portion using objective and reproducible method with MRI and evaluation of morphological change of corpus callosum by grade of hydrocephalus. MATERIALS AND METHODS: Midsagittal Tl-weighted MR imaging of the corpus callosum was investigated in 41 volunteers of normal Korean adults and 19 patients with hydrocephalus. Corpus callosum was measured for the anteroposterior length(A), height(B), and the thickness of genu(C), body (D), splenium(E), and the narrowest portion of body(F). And the analysis of morphology and signal intensity of the corpus callosum were also evaluated. Hydrocephalus was graded as mild, moderate, and severe, and comparision of thickness with normal corpus callosum in each portion was done. RESULTS: The mean length and height were 72.3mm, 28.6mm in male, and 70.7ram, 28.9mm in female. And the mean dimention for C, D, E, and F were 13.1 ram, 8ram, 13.2mm, 5.2ram in male, and 12.8mm, 7.5ram, 12.3 ram, 5mm in female. The morphology of normal corpus callosum was "hook" shaped on midline sagittal Tl-weighted image. Narrowing at posterior third portion of body were present on 30 cases(73.2%) and even in thickness of the body in 11 cases(26.8%). The signal intensity of the corpus callosum on midsagittal Tl-weighted spin echo image of normal cases was homogeneous hyperintense as compared with cerebral gray matter. In hydrocephalus, A and B were increased and other portions were decreased in thickhess. Genu and the narrowest portion of body showed significant difference of thickness according to the grade of hydrocephalus. CONCLUSION: The mean dimention of all portion of corpus callosum were larger in male than female except for callosal height but not significant statistically with the exception of splenium. Hydrocephalus lead to morphological change of the corpus callosum. Among the portion of corpus callosum, genu and the narrowest portion of the body were thought to be the most sensitive indicators of degree in hydrocephalus.

Biofeedback is the treatment of choice for functional defecation disorders such as idiopathic chronic constipation and neurogenic fecal incontinence. The pre-existing biofeedback systems have many disadvantages. The aims of current project are, first, to develop the biofeedback system into the application software in the Windows environment, and, second, to assess the possibility of clinical usage for patients with functional defecation disorders. The hardware and software of the BASCO (Biofeedback Anal Sphincter Control) system were based on the signal measurement and signal processing of anal sphincter EMG (Electromyography). BASCO system was applied to 5 normal healthy controls and 20 patients with functional defecation disorders. Patients group was categorized as constipation group (N1=15) and incontinence group (N2=5). With use of current system, EMG-based biofeedback therapy was performed, and the outcome was analysed. Anal EMG signal data was processed by the software, and displayed in the monitor of personal computer. The software of EMG-display and database management were adequately operated. In N1 group, a paradoxical elevation or equalized activity of anal EMG pattern was shown in the simulated defecation. In N2 group, low electrical activity was shown. These findings were used for the EMG-based biofeedback therapy as a pilot study. The clinical symptoms were improved in 12 of N1 group and 3 of N2 group in the period of 3.7 (range, 1~12) months follow-up. In Conclusion, newly-developed BASCO system was adequately operated in the volunteer and patients groups. The multi-tasking and multi-processing functions were adequately shown in the real time. Current results could be used for clinical appraisal. Specifically, this system could be used for the practical application of biofeedback therapy in the patients with chronic constipation or fecal incontinence.

The authors have made an anatomy CD titled Human Anatomy (Ministry of Culture & Tourism registration number 980052) for the self study by students and have used it in anatomy classes. For better student -centered and individual education, the introduction of remote education or interactive tutorial site was inevitable. In this study, amelioration report will be presented on the development and trials of this interactive tutorial site. Total hits for attending classes were 337.5 times, making 4.1 hits per student. About 76 messages were posted on the Q&A board, less than one per student. One assignment was given per lecture and all 82 students have submitted their report. Without delay after test, all students were able to check their grades and ranks between other students. Professors were able to evaluate the percentage of correct answers per question and the average of the score. An online discussion was held for 30 minutes after each lecture. On average, 37 students were participated in the discussion. After the term, evaluation survey in the remote education or interactive tutorial on the internet was made. Eighteen students (26%) have chosen 'good', 'bad' 13 students (19%), 'not much different' 38 students (55%). One the other side, 8 (12%)-'good', 19 (28%)-'not much different', 32 (46%)-'bad' figures were shown for remote examination. From this result, it is guessed that students who are not used to using computers have shown negative feeling from the burden that they had to use a computer to take exams, not demonstrating their full ability.

UItrasound provides the ideal means to examine the fetal developing organs and during the last few years urogenital anomalies in fetus have been discovered with increasing frequency. Obstuctive and non-obstructive urinary tract dilation have been diagnosed in utero as early as l4 weeks gestation and intrauterine intervention designed to relieve hydronephrosis have been performed even at 2l weeks gestation. The major benefit of prenatal ultrasound is to permit early identification of the fetus at risk and to enable treatment to be performed in the neonatal period before infection intervens to worsen the prognosis further. Recentry we have experienced 2 cases of fetal uropathy which was detected with obsterical ultrasonography and treated with neonatal corrective surgery.
