The depth of wound level is as important as the level of the tendon injury itself. And the timing of the operative procedure is an important factor. As a rule, tendons injured outside of the flexor sheath yield much better results than those injured within the sheath. The nutritional supply of the flexor tendons is not completely understood. Many elaborate studies have outilned the vascular anatomy of these tendons, and not all authors are in agreement. It is now clear that synovial fluid within the sheath supplies nutrition to the tendon much as synovial fluid in a joint supports cartilage. With this in mind, the present study was designed to determine the effect of exposing tendons for varying periods of time on the viability of the tendon and sequential morphological changes. The results are as follows: 1. Twelve hours after tendon sheath removal, collagen fibrillar dissociation and irregular surface of the tendon sheath were noted on the chicken flexor tendons by electronmicroscopy. 2. Superficial tenocyte necrosis was created after 24 hours of tendon exposure. 3. At 3 days, inflammatory cell infiltration and thickening of the outer synovial layer were noted. After 7 days, fibrosis of the degenerated tendon started from the exposed surface. 4. The fibrous connective tissue and new blood vessel infiltration into the tendon were progressed after 7 days. From these morphological results, any interference with the synovial environment leads to a regressive change of the flexor tendons immediately. It is suggested that delayed primary wound covering procedure within three days an after exposed tendon injury is ideal, and it should by done at least 7 days after tendon exposure.

168 patients with osteomyelitis who were admitted and operated in Department of Orthopedic Surgery, Seoul National University Hospital between January in 1972 and December in 1976 ware reviewed and analized. The following results were obtained. 1. 138 strains of bacteria were isolated from 167 pus culture in osteomyelitis, about 82.6% 2. Of these, 112 strains are staphillococcus aureus. (81.2%). 3. Degrees of Sensitivity to antibiotics were as follows: in sensitive order, cephalothin was 99.0%, gentamycin 98.0%, cloxacilnli 94.5%, lincocin 92.0%, kanamycin 86.3%, streptomycin 81.2%, and chloramphenicol 80.6% was resulted, 4. Resistant rate to antibiotics were as follows: in resistant order, penicillin 88.8%, oxytetracycline 79.6%, tetracycline 76.2%, and ampicillin 72.2% was resulted.

There is still discussion concerning the methods for treating Tossy type 3 dislocations of the acromioclavicular joint. Since 1995, the authors have treated 10 patients of type 3 dislocations by arthroscope-assisted modified Weaver and Dunn operation with favorable results. The operation consisted of diagnostic shoulder arthroscopy, arthroscopic resection of acromial end of coracoacromial ligament with bone block, excision of distal end of clavicle, bone block transfer of coracoacromial ligament into the medullary canal of clavicle, and augmentation between coracoid process and resected distal end of clavicle with the Mersilene tape. The advantages of this arthroscope-assisted modified Weaver and Dunn operation are as follows: (1) Using the shoulder arthroscope, associated patholgy in the shoulder joint can be found and treated appropriately. (2) Arthroscopic resection of the acromial end of coracoacromial ligament can give the small incision and least damage to the deltoid muscle so that immediate post-operative range of motion exercise can be possible. (3) Bone block transfer of coracoacromial ligament and augmentation between coracoid process and resected clavicular end can prevent displacement of the resected clavicular end.

OBJECTIVES: To evaluate the relation between diagnostic clinical parameters and the depth of trophoblastic invasion in tubal pregnancy and decide the most predictable parameter. Methods: Total 50 patients who were confirmed as tubal pregnancy pathologically, from Jan. to Dec. 1997, were included in this study. Menstrual missed periods was calculated by clinical history, volume of gestational mass was calculated as sphere, beta-hCG was titered with preoperative blood sample. All surgical specimens were examined pathologically and divided into two groups such as intraluminal and extraluminal, defined as intact tubal musculature and trophoblastic invasion beyond musculature, n=22 and n=28, respectively. Statistical analysis was performed among three parameters and between each parameter and the depth of trophoblastic invasion. Statistical analysis included were Student's t-test, Chi square, linear regression, and linear correlation analysis using SPSS statistical package and statistical significance was determined as p<0.05. RESULTS: There was a correlation between volume of gestational mass and beta-hCG(p<0.05), but not between beta-hCG and missed period or volume of gestational mass and missed period. beta-hCG level was 1843.7+/-1524.7 mIU/ml(Mean+/-SD) in intraluminal and 12144.3+/-10561.6 mIU/ml(Mean+/-SD) in extraluminal. There was a predictive correlation between beta-hCG and the depth of trophoblastic invasion(p<0.05), and cut off level 3,500 mIU/ml showed the highest sensitivity, specificity, positive predictive value, negative predictive value, 0.79, 0.86, 0.88, 0.76, respectively. Two parameters(volume of gestational mass and missed period) had no ability to predict whether intraluminal or extraluminal. CONCLUSION: We suggest that successful medical treatment of tubal pregnancy depend on lesional intactness of vasculature for drug delivery. In patient selection for medical treatment, it should be important to predict intraluminal type because of intact vasculature. Of clinical parameters, beta-hCG is single most predictive parameter, cut off level of 3,500 mIU/ml was the most reasonable level in this study.
