The application of the arthroscope to the shoulder joint has evolved in recent years for the purpose of diagnosis and treatment. This paper presented 11 cases with various shoulder diseases treated by arthroscopy during the period from January, 1984 to September, 1985 in the Department of Orthopedic Surgery, College of Medicine, Soon Chun Hyang University. The advantages of the arthroscopy were as follows: 1. The arthroscopy made it easier to diagnose the unsolved cases by direct biopsy on the pathologic lesions in the joint. 2. The damage on the inside and outside of the shoulder joint was minimal and the post-operative incision scar was acceptable cosmetically. 3. The limitation of the joint motion did not remain due to early exercise post-operatively. 4. The complications such as infection, neurovascular injury, scuffing of joint cartilage, etc. could be avoided.

PURPOSE:To evaluate the factors influencing the prognosis in avascular necrosis(AVN) of the femoral head by MR. MATERIALS AND METHODS:Radiographic and MRI findings of twenty-three patients(30 cases, aged 23-67 years) with AVN identified clinically and radiologically were evaluated. The radiography included follow up study for at least 6 months. The mean age of these patients was 43 years and M: F ratio was 20: 3. MR imaging was performed at 1. 5T unit using T1- and T2-weighted coronal and Tl-weighted sagittal and axial spin echo sequences. We categorized the changes of the femoral head on radiographic follow-ups to three grades of mild, moderate and severe. We also analyzed the changes of the signal intensity and sizes of the lesion at sagittal and coronal MR images. On MR imaging we classified the extent of AVN of the fernoral head to 2 grades according to the size of lesion. RESULTS:In the cases of mild changes in fernoral head on radiography, the mean age of the patient was 37 years and the extent of AVN was below 1/2 in eleven out of seventeen cases. In the cases of moderate changes, the mean age was 43 years and the extent was above 1/2 in five out of seven cases. In the cases of severe changes, the mean age was 60 years and the extent was above 1/2 in all 6 cases. With 95% confidence coefficient, comparisons in the age and necrosis extent revealed statistical significance in severe versus moderate changes and in severe versus mild changes. Comparisons in the change of signal intensity on T1 and T2 weighted images showed no statistical relationship between each other. CONCLUSION: We conclude that if patient is younger and has smaller extent of the AVN, bone destruction is slower that these factors may be helpful in predicting the prognosis of AVN. However, the modes of the changes of the signal intensity on T1- and T2- weighted images may not be useful in predicting the prognosis of AVN.

Postherpetic neuralgia is the most frequent complication of herpes zoster. Treatment of this neuropathic pain syndrome is difficult and often disappointing. Although postherpetic neuralgia is generally a self-limited condition, it can last indefinitely. Continuous epidural blockade for patients with acute zoster can shorten the duration of treatment. However, continuous epidural block has some complications such as infection, dural puncture, and total spinal and nerve damages. We report a case of myoclonus during continuous epidural block with ropivacaine, morphine, and ketamine in an acute zoster patient.

We compared all frozen section examination of ovarian tumors during a 5 year period in our institute with permanent section diagnosis from paraffin sections. In this period, 604 ovarian tumors had frozen section examination. Final histologic diagnosis was divided into benign, low malignant potential and malignant. Sensitivity of frozen section diagnosis for malignant was 80 %, low malignant potential 73,1%, and benign 99.8%. Predictive value for malignancy was 98.5%, for low malignant potential 76.6%, and for benign disease 96.2%. Diagnostic problems occurred in huge tumors and low malignat potential mucinous tumors. Analysis of the 32 false negative(miss or under diagnosis) revealed that a sampling error was involved almostly. The cases of discrepancy between frozen section diagnosis and permanent section diagnosis, were 26/34 in mucinous tumors and 33/34 in huge size of tumors(more than 10cm). Although surgeons and pathologist are aware of the limitations of frozen section diagnosis of ovarian tumors, peroperative histologic examination can be worthwhile and prevent under or over treatment of ovarian malignancies.

PURPOSE: To evaluate the sensitivity of MR imaging in determining tear sites and degrees in acute anterior cruciate ligament tear. MATERIALS AND METHODS: MR imagings were undertaken in 19 patients who had trauma on their knee joints. All imaging studies were performed within 2 weeks after trauma and compared with operative findings. The degrees of ligament tear were divided into complete and incomplete, and sites of tears were divided into superior middle and inferior portions. MR findings were compared with operative findings. RESULTS: There were 14 cases of complete ligament tear and 5 cases of partial ligament tear. We could diagnose correctly in all 14 cases with complete tear and in 3 of 5 cases with partial tear. The tear sites were correctly predicted in 10 of 14 cases with complete tear(71%) and 1 of 5 cases with par In complete tears, MR findings were transversely or obliquely coursed band-like high signal intensity within the ACL or abrupt Switch over to as indistinct signal intensity. In partial tears, the tear sites could not be evaluated mostly and the tear appeared as linear low signal intensity lesions in posterolateral bundles of AC/. CONCLUSIONS: MR revealed higher sensitivity in determining the degree and sites of ACL tear in complete tear as compared with partial tear.
