Congenital Abnormalities

Rupture of the anterior cruciate ligament is a serious injury that can cause severe degenerative change if untreated, and there are many controversies in its treatment. The authors experienced 126 patients of the anterior cruciate ligament rupture in the Department of Orthpaedic Surgery, Chung-Ang university from May 1985 to December 1992. Among them, we performed 36 anterior cruciate ligament reconstructions using bone-patellar tendon-bone autograft reinforced with Trevira ligament, an assumption that the artificial ligament acts as an internal splint during the vulnerable period of healing. Bone-patellar tendon-bone autograft was passed through the transosseous hole in the tibia, then across the knee and through the isometric path of lateral femoral condyle through a bone tunnel. Thereafter, the Trevira ligament was passed through the same tibial tunnel, but over the top route to the lateral femoral condyle. Of the 36 cases, 28patients (Group I: 15 cases of Mini-arthrotomy,Group II: 13 cases of Arthroscopic technique) with average follow up of 23.5 months (minimum 12 months, maximum 40 months) were analyzed. According to the Mullers criteria, the result were excellent in 12 cases (Group I: 5 cases; Group II: 7 cases), good in 14 cases(Group I: 9 cases ; Group II: 5 cases and fair in 2 cases (Group I: 1 case; Group II: 1 case). On stress roentgenograms by Telos arthrometer, the average difference of anterior displacement between the injured and normal sides were decreased to 2.3mm from average 9.1mm preoperatively (Group I: from 9.3mm to 2.6mm; Group II: from 8.8mm to 2.1mm). And subjectively, there was no difference between the injured and normal sides in 8 cases (Group I: 4 cases, Gruop II: 4 cases).

There are many options for the management of osteoarthritis of the knee joint. Recently, arthroscopic surgery has been added to the armamentorium of the treatment modalities in osteoarthritis of the knee which does not respond to conservative treatment. Among 74 arthroscopic pocedures(including partial menisectomy, removal of loose bodies, synovectomy, cartilage drilling and simple lavage) done for osteoarthritis of the knee, 68 patients studied at average 3.1 years after procedure and the results were as follows 1. Seventy-one percent of patients had at least 2.5 years or more relief of pain and symptoms. 2. Fifty-six percent were still good at follow-up of 3.1 years. 3. The best result were obtained after removal of loose bodies and resection of unstable flap tear of a meniscus in association with mild osteoarthritis. 4. The poor result were obtained in patients with severe degenerative changes of both femoral condyle, 5. The results were much better in the normally aligned knee compared with valgus knee.

Nineteen cases out of over 100 cases which had been reconstructed the deficient anterior cruciate ligament(ACL) by the bone-patellar tendon-bone(BPTB) autograft 12 months before or more(mean 15.8 months) were evaluated during the second-look arthroscopy. Before the second-look, the patients were evaluated the clinical results of ACL reconstruction by the Müller's knee rating score and the radiographical results by the lateral roentgenography of the fully extended knees. The location of the center of tibial tunnel from the anterior end of the line of the tibial plateau was 35.2%(range, 22 to 47%) on average. The average intercondylar roof angle was 36.6 degrees(range, 28 to 45 degrees). The mean percentage of roof impingement was

PURPOSE: To evaluate the functional outcome after surgical treatment for displaced fractures of proximal humerus and assess the final results according to surgical methods. MATERIALS AND METHODS: Thirty-three cases with follow-up over 12 months were divided into three groups: double tension band wiring (Group I, 14), plate fixation (Group II, 10) and closed reduction with internal/external fixation (Group III, 9). The pain index, the self-assessed functional score and the range of motion were obtained. RESULTS: Anatomical reduction was best obtained in group II and fractures united in 11-16 weeks. The pain index was worst in group III and the functional score of group I (80+/-12.2%) was higher than in the others (II: 69+/-15.7%, III: 55+/- 7.9%). The range of motion was worst in group III. Complications were noted in 9 cases, which occurred mostly in group II and III. CONCLUSIONS: Double tension band wiring in displaced proximal humerus fracture demonstrated that it provides a sufficient fixation for early rehabilitation and union, while minimizing complication

Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

This experiment was performed the effect of the glycoconjugates of the skin in the Sprague-Dawley male rats exposed to SO2 for 1, 3 and 6 hours with various concentrations (10, 25, 50, 100 and 200 ppm). To investigate the change of glycoconjugates of skin, seven biotinylated lectins (DBA, SBA, PNA, BSL-1, sWGA, UEA-1, Con A) were applied with ABC method. The epidermis of experiment rats was more or less different according to the concentration of SO2, comparing control group, and beta-N-acetyl-D-galactosamine, alpha-L-fucose, alpha-D-mannose and alpha-D-glucose of the epidermis tend to be increased according to exposed SO2 time, but alpha-D-galactose was tend to be decreased. Galactose-beta-1, 3-Nacetyl- D-galactosamine was tend to more or less increase in horny layer of the epidermis, but decrease in granular and spinous layers. As contrasted control group, beta-N-acetyl-D-glucosamine in the dermis of experiment rats was decreased, but alpha- D-mannose and alpha-D-glucose were increased. In the hair follicle of the experiment rats, beta-N-acetyl-D-galactosamine and galactose-beta-1, 3-N-acetyl-Dgalactosamine tend to be decreased according to exposed SO2 time though more or less differ from the portions of the hair follicle, and beta-N-acetyl-D-glucosamine and alpha-L-fucose were found noticeably to increase comaring control group. According to exposed SO2 time, the decrease of alpha-D-galactose tend to be little more pronounced in the outer root sheath of the upper portion of hair follicle. In contrast, the same sheath of the upper portion in above follicle was increased relatively. alpha-D-mannose and alpha-D-glucose were increased in the root sheath of hair follicle and hair cortex, but decreased in the hair medulla. In the experiment rats, the beta-N-acetyl-D-galactosamine tend to be decreased gradually according to exposed SO2 time, but the decrease of galactose-beta-1, 3-N-acetyl-D-galactosamine were showed significantly as contrasted control group. beta-N-acetyl-D-glucosamine, alpha-D-mannose and alpha-D-glucose were increased gradually according to exposed SO2 time, but alpha-L-fucose was increased remarkably. The effect on lectin binding pattern of the glycoconjugates in the rat skin according to the concentrations and exposed time of SO2 was noted that the alternations of lectin binding pattern tend to be a little more pronounced in low concentration of exposed SO2 for a long time than in high concentration of exposed SO2 for a short time. The alternations of lectin binding pattern were appeared almost similar in concentrations of 50 ppm SO2 and above.
