BACKGROUND: Acromioclavicular (AC) stability is maintained through a complex combination of soft-tissue restraints that include coracoclavicular (CC), AC ligament and overlying muscles. Among these structures, the role of the CC ligament has continued to be studied because of its importance on shoulder kinematics, especially after AC injury. This study was designed to determine the geometric change of conoid and trapezoid ligaments and resulting stresses on these ligaments according to various scapular motions. METHODS: The scapuloclavicular (SC) complex was isolated from a fresh-frozen cadaver by removing all soft tissues except the AC and CC ligaments. The anatomically aligned SC complex was then scanned with a high-resolution computed tomography scanner into 0.6-mm slices. The Finite element model of the SC complex was obtained and used for calculating the stress on different parts of the CC ligaments with simulated movements of the scapula. RESULTS: Average stress on the conoid ligament during anterior tilt, internal rotation, and scapular protraction was higher, whereas the stress on the trapezoid ligament was more prominent during posterior tilt, external rotation, and retraction. CONCLUSIONS: We conclude that CC ligament plays an integral role in regulating horizontal SC motion as well as complex motions indicated by increased stress over the ligament with an incremental scapular position change. The conoid ligament is the key structure restraining scapular protraction that might occur in high-grade AC dislocation. Hence in CC ligament reconstructions involving only single bundle, every attempt must be made to reconstruct conoid part of CC ligament as anatomically as possible.

There has been numerous experimental liver transplantation models in the rodent : orthotopic versus hetrerotopic; whole liver versus partial liver; microvascular suture versus cuff method in technical aspects. Several simplified modifications were introduced for experimental liver transplantation for improving animal-survival rate. Liver transplantation without arterial reconstruction, the cuff tchnique or stent method were the examples of simplifing modification. In practice, complications related to biliary reconstruction are frequent causes of intraabdominal infection in our rat liver transplantation. Here we propose using simple liver transplantation model of partial heterotopic liver transplantation without artery and bile duct reconstruction in the studies which need only observation of immediate graft survival or very short-term follow-up. Here we examined the serial histologic changes of auxiliary liver grafts without biliary reconstruction during short period after transplantation. Until 7 days of transplantation, bile duct proliferation was confined in the portal area of grafts and did not distort the lobular structure. Early graft-survival and rapid immunologic response might be evaluated by this easy transplantation model.

BACKGROUND: Smoking increases the risk of respiratory, cardiac diseases and cancer. This study is to ascertain the relationship between passive smoking, the modes of residence, its location and the immunoglobulin values as well as the eosinophil counts in relation to child patients suffering from bronchial or cardiac asthma. METHODS: The research was conducted at a general hospital with cooperation of 242 patients who had been hospitalized 1991 through 1995. We compared the average values of immunoglobulin between the groups of exposed and non-exposed to smoking by T-test. A same work for residential modes was done by T-tests, while the data regarding the residing locality were processed by ANOVA. RESULTS: Each values of TEC, IgE, IgA, and IgM in both groups has been analysed but spelling no significant differences. The group residing in apartments showed lower value of IgM than those of flats. CONCLUSIONS: The reason the IgM value of apartments is lower than that of flats is due to the difference of living quarters. This signifies the modes of residence may as well affect the IgE value.

Epiblepharon is frequently encountered n oriental eyelid, especially in children. It is characterized by a horizontal fold of redundant skin and abundant orbicularis muscle near lid margin, which the lashes vertically, or posteriorly towards the eye. Surgical therapy of epiblepharon in correcting the trichiasis includes lid bracing sutures, burried sutures, skin resection, a Hotz procedure or its modification, and a Jones procedure. In our opinion, these procedures are not sufficient, because these procedures will not correct the epicanthal folds. Epicanthal folds have been a one of the characteristics of Asian over 50 percents of population in Japan and South Korea, and it either reduce the aesthetic result of the double-eyelid procedure or make the correction of the entropion and epiblepharon difficult. Although many surgical procedures are available to eliminate epicanthal folds, scarring on the medial canthus is in still and obstacle for surgeons to overcome. From January of 1998 to October of 1998, we used half z-plasty procedures in 5 cases to correct epicanthal folds in epiblepharon. There were few complications in our series. We believe that half z-plasty can get a good result in the correction of epibolepharon and oriental epicanthal folds.

Purpose: To report the surgical skills needed, and the clinical results of, minimally invasive hip surgery with dynamic hip screws and the comparison with the classical technique in stable pertrochanteric fractures of the femur. Materials and Methods: Thirty-two patients with pertrochanteric fractures of the femur who were treated with dynamic compression hip screws between April 1999 and March 2004, and were evaluated retrospectively, and were followed up for more than 12 months. 16 cases were treated with a classical dynamic hip screw technique and 16 cases with a minimally invasive technique in random order. The mean age was 73.2 years, and there were 11 males and 21 females. The operative times, total hemovac bleeding loss, functional scores, and average hemoglobin decrease ratios were evaluated. The clinical assessments were performed with the Harris Hip Score (HSS) and bony union was evaluated with serial follow-up plain radiographs. Results: The average operative time was 63.9 minutes with the classical technique and 42.5 minutes with the minimally invasive technique. The total average hemovac blood loss was 640 cc with the classical technique and 143 cc with the minimally invasive technique. Clinically, the HHS was an average of 85.9 and 89.2 in groups 1 and 2, respectively, by the last follow-up and there were no statistically significant differences between the two groups (P <0.05) The hemoglobin decrease ratio was the same in both groups and there was no nonunion. Conclusion: Minimally invasive dynamic hip screw insertion was useful in stable pertrochanteric fractures, because it decreased blood loss and operative times; and there were no changes in fracture healing and functional outcomes.
