BACKGROUND: The consensus is that a bony Bankart lesion shorter than 25% of the length of glenoid does not affect the clinical result; hence, such lesions were often neglected. However, small bony Bankart lesions are associated with various types of capsulolabral lesions. METHODS: A total of 82 patients who had undergone arthroscopic capsulolabral lesion repair surgery for anterior shoulder dislocation were reviewed. The prevalence rates of early and late type of capsulolabral lesions were compared between a group of patients with and a group without small bony Bankart lesions. In addition, the types of accompanying capsulolabral lesion were analyzed according to the type of bony Bankart lesion. Finally, the clinical outcomes were evaluated (active range of motion, American Shoulder and Elbow Surgeons score and Rowe's score). RESULTS: Among the 13 patients who had small bony Bankart lesions, the prevalence rate of early and late type of capsulolabral lesions was 38.5% and 61.5%, respectively. Among the 69 patients without bony Bankart lesion, the prevalence rates of early and late type of capsulolabral lesions were 74% and 26%, respectively. Significantly worse clinical outcome was observed for the group of patients with both small bony Bankart lesions and late type of capsulolabral lesion. CONCLUSIONS: More severe type of small bony Bankart lesion appears to be associated with late type of capsulolabral lesion. The significantly worse clinical outcome for patients with both small bony Bankart lesion and late type of capsulolabral lesion indicates that small bony Bankart lesions cannot always be neglected.

Effects of several cytokines(IL -1beta, TNFalpha, and IFNgamma) have been examined on fetal rat osteoblast-like cells. To investigate whether cytokines play direct causal roles in production of lysosomal enzyme, fetal rat osteoblast-like cells were treated with IL-1beta, TNFalpha, and IFNgamma, respectively or combined. And acid phosphatase was determined by biochemical method. Alkaline phosphatase was assayed to determine the effects of IL-1beta, TNFalpha, and IFNgamma on the expression of this enzyme. And also experiment of calcified nodule formation was performed to assess the effects of cytokines on the bone-forming activity of osteoblast-like cells in vitro. Acid phosphatase activity was significantly increased by the addition of IL-1beta and TNFalpha, whereas decreased by IFNgamma, However, no significant changes in alkaline phosphatase activity was observed when the osteoblast-like cells were treated with IL-1beta and TNFalpha. Interestingly, IFNalpha showed stimulatory effect on alkaline phosphatase activity. The number of calcified nodules was decreased by treatment of cultures with 1ng/ml IL -lbeta, 20ng/ml TNFalpha, and 500 u/ml IFNgamma continuously for 21 days, while considerable number of calcified nodules were formed in control group of osteoblast-like cell in culture for 21 days. These results seem to suggest that cytokines may play crucial roles in bone remodeling through the direct action on the osteoblast-like cell.

Between sept. 1982 and June 1985, the authors have performed arthroscopic debridement on 32 knees of 30 patients with primary osteoarthritis of the knee. Operative procedures including lavage, partial meniscectomy, excision of shelf, partial or total synovectomy of the anterior compartment, debridement of the articular cartilage, removal of loose bodies and multiple drilling of the articular cartilage were variously combined case by case. The follow-up period was between 18 and 52 months, with on average of 30.6 months. Clinical results were evaluated with the modified method of Sprague, III and were classified “Excellent”. “Good”, “Fair” and “Poor”. The data were analyzed by Fishers exact test to clarify the relationship between clinical results and various preoperative factors. The results were as follows: l. Of the total 32 knees, results were “excellent” in 17(53.1%), “good” in 9(28.1%), “fair” in 3 (9.4%) and “poor” in 3(9.4%) knees respectively. Satisfactory results, including “excellent” and good, were achieved in more than 3/4 cases(81.2%) . 2. Of the 3 “poor” cases, 2 cases seemed to be affected by major depression and the other one case had no specific cause to be considered. 3. The unsatisfactory cases, including “fair” and “poor” cases, commonly had degenerative changes of patellofemoral joint arthroscopically although the correlation between it and the results were not significantly proved statistically(P>0.05). 4. The correlation between amount of effusion, degree of degeneration of articular cartilage and amount of fibrinoid debris were not significantly proved statistically(P>0.05). 5. The correlation between clinical results and amout of effusion. degreq or site of degeneration of articular cartilage, degree of flexion contracture, meniscal tear, synovectomy, debridement of articular cartilage and number of operative procedures could not be significanly proved statistically. In conclusion, arthroscopic treatment of the primary osteoarthritis of the knee shows relatively satisfactory results in most cases with fewcomplications and a short rehabilitation period, and the procedure could be recommended as a process inbetween conservative treatment and definitive treatment such as total knee replacement. But any specific relationship between clinical results and various preoperative factors could not be proved statistically. The clinical results seemed to be attected by individual unknown factors and further precise analysis and long term follow-up will be necessary to clarify them.

Papineau's technique represents an excellent method of dealing with serious bone infections with significant bone and soft tissue loss. The procedure is carried out in three stages: the 1st stage is the excision of infected bone and soft tissue, stabilization of the fracture site, the 2nd stage is the cancellous bone grafting, and the 3rd stage is the skin coverage. During the period from June 1980 to September 1982, our limited experience with 14 cases has been extremely satisfactory; 1. This method is applicable to traumatic osteomyelitis and some cases in which the infection has been blood borne. 2. Successful bone grafting in the presence of infection depends upon; a. complete sequestrectomy and removal of all infected tissue b. an adequate vascular bed for the graft c. no dead space d. sufficient immobilization.

This study was conducted to evaluate the effect of ambroxol on preventing the infantile respiratory distress syndrome (IRDS) in preterm birth at the Dept. of Obstetrics and Gynecology of Taegu Catholic Medical Center during the period from Jan. 1996 to Dec. 1996. Total of 68 cases were evaluated including 16 ambroxol group and 52 control group. The result were as follows : 1. In the comparison of preventing IRDS, there was 0 case of IRDS in ambroxol group and 7 cases of IRDS in control group (13.46 %). There was a significant difference between two groups (p<0.05). 2. The side effects of ambroxol after administration were nausea in 5 cases, headache in 3 cases, and chest discomfort in 4 cases, but these were not serious and self controlled. 3. There was no significant difference in neonatal morbidity between two groups (p > 0.05).

STATEMENT OF PROBLEM: In cases where bony defects were present, guided bone regenerations have been performed to aid the placement of implants. Nowadays, the accepted concept is to isolate bone from soft tissue by using barrier membranes to allow room for generation of new bone. Nonresorbable membranes have been used extensively since the 1980's. However, this material has exhibited major shortcomings. To overcome these faults, efforts were made to develop resorbable membranes. Guided bone regenerations utilizing resorbable membranes were tried by a number of clinicians. Bio-Gide. is such a bioresorbable collagen that is easy to use and has shown fine clinical results. PURPOSE: The aim of this study was to evaluate the histological results of guided bone regenerations performed using resorbable collagen membrane(Bio-Gide.) with autogenous bone, bovine drived xenograft and combination of the two. Surface morphology and chemical composition was analyzed to understand the physical and chemical characteristics of bioresorbable collagen membrane and their effects on guided bone regeneration. MATERIAL AND METHODS: Bioresorbable collagen membrane (Bio-Gide.), Xenograft Bone(Bio-Oss), Two healthy, adult mongrel dogs were used. RESULTS: 1. Bioresorbable collagen membrane is pure collagen containing large amounts of Glysine, Alanine, Proline and Hydroxyproline. 2. Bioresorbable collagen membrane is a membrane with collagen fibers arranged more loosely and porously compared to the inner surface of canine mucosa : This allows for easier attachment by bone-forming cells. Blood can seep into these spaces between fibers and form clots that help stabilize the membrane. The result is improved healing. 3. Bioresorbable collagen membrane has a bilayered structure : The side to come in contact with soft tissue is smooth and compact. This prevents soft tissue penetration into bony defects. As the side in contact with bone is rough and porous, it serves as a stabilizing structure for bone regeneration by allowing attachment of bone-forming cells. 4. Regardless of whether a membrane had been used or not, the group with autogenous bone and Bio-Oss. filling showed the greatest amount of bone fill inside a hole, followed by the group with autogenous bone filling, the group with blood and the group with Bio-Oss. Filling in order. 5. When a membrane was inserted, regardless of the type of bone substitute used, a lesser amount of resorption occurred compared to when a membrane was not inserted. 6. The border between bone substitute and surrounding bone was the most indistinct with the group with autogenous bone filling, followed by the group with autogenous bone and Bio-Oss. filling, the group with blood, and the group with Bio-Oss. filling. 7. Three months after surgery, Bio-Gide. and Bio-Oss. were distinguishable. CONCLUSION: The best results were obtained with the group with autogenous bone and Bio-Oss. filling used in conjunction with a membrane.

PURPOSE: To report the treatment results of 7 cases of distal radius nonunion with a review of the relevant literature. MATERIALS AND METHODS: Seven patients treated with an autoiliac bone graft and rigid internal fixation for nonunion of the distal radius were analyzed retrospectively for the cause of injury, the factors affecting nonunion, radiological findings, treatment method and complications. The results were analyzed radiologically using Kreder's method and functionally using the Anderson' protocols. RESULTS: Union was achieved in all cases after a mean period of 19 weeks. The functional result of treatment at the last follow-up was excellent in 4 cases and satisfactory in 3 cases. The probable factors of nonunion were instability of the fracture site in three cases, type II or III open fracture in 2 cases, postoperative infection in one case and idiopathic in one case. CONCLUSION: Infection control using a stepwise operation, rigid internal fixation and autogenous iliac bone graft showed satisfactory results in distal radius nonunion, which had developed in those with severe open fractures, postoperative infection, instability on the fracture site and associated distal ulnar fracture.
