Fractures at the lateral end of the clavicle inevitably require surgical treatment as there is high potential for delayed union or nonunion. Acromioclavicular dislocation also requires stable and solid fixation for healing, and surgical treatment is recommended for the maintenance of joint function. The hook plate maintains the biomechanics of the acromioclavicular joint, enabling early range of motion. Therefore, for the past 10 years, the hook plate has been widely used in distal clavicle fractures and acromioclavicular joint injuries. However, the hook plate is associated with several complications, such as proximal clavicle fractures, widening of the hook hole, rotator cuff tear, subacromial impingement, and often acromial fractures. We report on two unusual cases of acromion fracture after hook plate fixation in patients with distal clavicle fracture and acromioclavicular dislocation alongside a literature review.

OBJECTIVES: Cell adhesion molecules may play a role in integrating amnionic membrane. The objective of this study was to prove E-cadherin mRNA and proteins in cultured human amnionic cells. METHODS: We cultured amnionic cells from 4 women undergoing cesarean section without labor. E-cadherin was determined by immunohistochemistry and Western ligend blotting. To demonstrate E-cadherin mRNA, reverse transcription-polymerase chain reaction was performed. RESULTS: On immunohistochemistry, E-cadherin was abundantly showed on the cytoplasm of the cells. Western ligend blotting showed clear 120 kDa bands on four specimens, and relatively weak band on one specimen. Reverse transcription-polymerase chain reaction showed 432 BP bands. CONCLUSION: We proved E-cadherin and its mRNA by immunohistochemistry, Western ligend blotting and reverse transcription-polymerase chain reaction in cultured human amnionic cells.

The purpose of this study was to find the distribution and measurement of compressive and tensile stress when intrusi- on arch wire is forced engage with upper canine and to analysis stress at each section through FEM. And we compare compressive and tensile ratio at each section. The results were as follows. 1. At FA point and cemento-enamel junction of upper canine, compressive and tensile force ratio is about the same. 2. At apex, compressive force is the four times as tensile force. ; In intrusion, we show root resorption at apex. 3. At Cemento-enamel junction, the compressive and tensile force show the maximun value except FA point.

The purpose of this study was to investigate the patency rates and the histologic findings of neoen- dothelialization according to the length of implanted polytetrafluoroethylene (PTFE) with an internal diameter of 3 mm. Under the operating microscope, grafts of 8 and 24 mm in length were implanted in the right carotid arteries of thirty rabbits by interrupted end-to-end microanastomosis. They were divided into two groups according to the length of implanted PTFE. Each group compised fifteen rabbits. All implanted grafts were 25 pm in fibril length and 0.39 mm in wall thickness. Three grafts per group were harvested at 1, 2, 4, 8, and 12 weeks after implantation respectively and all grafts were observed for patency rates and the histologic findings with light microscope and scanning electron microscope. In conclusion, there was no difference in patency rates according to the length of implanted PTFE and histologically the formation of neointima and subintimal tissue was delayed and incomplete in longer implanted PTFE.
