In the treatment of posterior cruciate ligament injury, posterior displacerrient of tibia might be occured because of the direction of gravity due to weight of lower leg. To prevent this problem several methods have been introduced, but not settled yet. Therfore the author tried to solve this problem by applying Quengel brace that was firstly described by Mommsen in 1922 and perfected by Jordan using the correction of flexion contracture of the knee in hemophiliacs. But owing to the development of some problems in original hinge for prevention of posterior displacement of tibia after posterior cruciate ligament injury, we modified the design of the hinge that more effective anterior traction force should be operated on tibia. The authors applied Quengel brace including original and modified hinge to 21 cases of posterior cruciate ligament injury between June 1983 and May 1986. The followings were obtained. 1. By modification of the hinge, more effective anterior traction force operated on tibia without pressure sore or joint narrowing. 2. On clinical application of modified Quengel brace, posterior displacement of tibia were prevented effectively.

The humerus is anatomically and phyelologically unique, such as, firstly, it is a non weight bearing bone, secondly, it has greatest range of motion, thirdly, when at rest while the person is standing, the axis of bone hangs vertically and is influenced by gravity, and conservative methods usually used in treatment. However, in the event of closed reduction failure, open fracture, multiple fracture, and old age, operative method may be employed. Authors reviewed and analzed 84 humeral shaft fractures which had been treated at the Department Orthopedic Surgery, Paik Hospital from Dec. 1979 to May 1988. The results were as follows : l. Among the 84 patients, male were 63 and female were 21. 2. The major causes of injury were a traffic accident. 3. The most frequent type and site of fracture was comminuted and middle one third. 4. The incident of radial nerve injury was 17 cases. 5. Of 84 cases, 22 cases were treated conservatively and 62 cases operatively. 6. The most common complication was non-union of 14 cases, of which 10 cases were treated with plate and bone graft and 4 cases with only bone graft.

To investigate the pathogenicity, genomic pattern, and o-like hemolysin of Staphylococcus lugdunensis (S. lugdunensis) in acute oral infection, S. lugdunensis was isolated from patients with an acute oral infection and from healthy persons. Antibiotic susceptibility, in vitro cellular toxicity, in vivo virulence, and hemolytic activity were tested, and plasmid DNA and restriction pattern of whole genomic DNA were analyzed to characterize the staphylococci. The dot blot and Southern blot hybridization analysis of staphylococcal DNA were performed with o-hemolysin gene probe. The isolation ratio of S. lugdunensis in the patients was higher than that in the healthy persons. S. lugdunensis from the patients with an acute oral infection showed resistance to penicillin, ampicillin, methicillin, cephalothin, and clindamycin. In the analysis of plasmid, there was a clear band about 6.5 kb in three strains of S. lugdunensis isolated from the patients with infection. S. lugdunensis in the patients had cellular toxicity in vitro and virulence in vivo. All strains of S. lugdunensis had o-like hemolysin activity against rabbit erythrocytes. Four of the six strains of S. lugdunensis gave synergistic hemolysis with Staphylococcus aureus (S. aureus) on sheep blood agar plates. In the analysis of genomic pattern, four strains of S. lugdunensis that gave synergistic hemolysis with S. aureus showed a similar genetic pattern with HindIII enzyme digests. In dot blot analysis, all strains of S. lugdunensis showed a positive reaction with the probe of 5-hemolysin gene in S. aureus. In Southern blot analysis, a 7.3 kb HindIII fragment was observed in DNA of S. lugdunensis that gave synergistic hemolysis with S. aureus, and a 2.5 kb band was observed in HindIII digests of S. aureus in the patients. These results suggest that S. lugdunensis may be an important pathogen in an acute oral infection and the 7.3 kb HindIII fragment from S. lugdunensis DNA may contain o-like hemolysin gene.

We report a case of infantile digital fibromatosis in a 34 month-old boy, who presented with a painless subcutaneous tumor on the medial aspect of the left third toe. A histological examination showed scattered small, round eosinophilic inclusion bodies in the cytoplasm of the tumor cells, which was consistent with infantile digital fibromatosis. A'immunohistochemical study revealed that desmin, a-smooth muscle actin, and vimentin were clearly positive in the cytoplasm of the tumor cells, but the inclusions themselves showed negative staining, thus indicating a hollow-like staining pattern. Electron microscopy showed either well-defined or ill-demarcated dense bodies in the cytoplasm of the tumor cells. In some areas, small vesicles and intracellular organells were observed' in the inclusions. In the course of conservative treatment, a new lesion developed on the lateral aspect of the left third toe, seven months after the appearance of the initial lesion.

We report a case of subcutaneous fat necrosis associated with pancreatitis that may be the first case in Korean hterature as for we know. The patient was a 41-year-old man wbo presented erythema nodesum-like erythematous subcufaneous nodules on both lower extremities. Histopathologic findings showed subcutaneoms focal fat necrosis and ghoat-like cells. Granular basophilic material was deposited in and around the necrotic fat cells and stained positively with von Kossa stain. The lesioas subsided gradwdly without any specific treatment, as the underlying pancreatitis was ameliorated.

Sternocostoclavicular hyperostosis is a rare syndrome characterized by hyperostosis and soft tissue ossification between the clavicle and the anterior part of the upper ribs. Since first reported in 1974, the syndrome has been noted predominantly in Japan(1). Our case report describes the disorder and its radiologic manifestations.
