BACKGROUND: The purpose of this study was to evaluate the applicability of the Korean version of Fall Efficacy scale(FES) and Activities-specific Balance Confidence Scale(ABC) to Korean older adult through an examination of instrument`s internal consistency and validity METHOD: A sample of 90 Korean older adults who lived in a community completed a survey instrument which included Korean version of FES and ABC. Because of comparable data derived from each scale, fear of falling and quality of life, activity daily living were included. Concurrent validity, criterion validity and correlational validity were tested. Reliability was tested by internal consistency, test-retest method. RESULTS: Cronbach`s alpha was 0.9043 in FES, and 0.99623 in ABC. Test-retest correlations in all scales were higher than 7.0. Statistically significant association was found between fear of falling and both scales. Correlation coefficient between Quality of life(SF-8) and ABC was -0.142(p=0.049). Both FES and ABC are correlated significantly each other. CONCLUSION: The Korean version of FES and ABC appears to be a reliable and valid method for meas- uring fear of falling. These instruments may be useful in assessing the independent contribution of fear of falling. ABC scale may be more useful to detect loss of balance confidence in more highly functioning seniors.

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.

Hobnail hemangioma(HH) is a benign acquired vascular tumor of endothelial origin which should be differentiated from other malignant vascular neoplasm such as Kaposi's sarcoma or angiosarcoma. We report a case of hobnail hemangioma in a 21-year-old woman who had a dusky-red patch on her left shin. Histologically, ectatic vascular channels with a single layer of plumped endothelial cells were seen and the vascular channels seemed to dissect the collagen bundles. She underwent treatment with surgical excision with primary closure.

Atypical cutaneous fibrous histiocytoma (ACFH) is not well known and only a small number of cases have been reported. Characteristically, ACFH is found on the trunk and limbs of middle-aged women. Although considerable cellular atypia may be present, it occurs focally, the remainder of the tumor representing more classical cutaneous fibrous histiocytoma. A 37-year-old woman presented with a solitary brownish firm nodule on her right forearm. No other abnormalities were found in her personal or family history. Clinically, the tumor simulated a benign fibrous histiocytoma. Histologic examination revealed a poorly delineated intradermal tumor with the usual appearance of benign cutaneous fibrous histiocytoma, but a variable pro-portion of cells in the tumor were scattered atypical cells or bizarre multinucleated giant cells. We report upon a rare case of ACFH.

In Korea, there are about 8 million motor vehicles and one-fourth of it is motorcycle. Last year Korean government report on the motor vehicle accidents claimed 12,781 cases of motorcycle accidents and it account for 5.1% of all of motor vehicle accidents occurred in Korea. But this is too broad analysis and lack of statical values. In general, most of people think motorcycle rider will suffer or die from head injuries sustained with motorcycle accident. Even though mandatory law on wearing helmet during motorcycle ride, but we see too many motorcycle riders not wearing helmet, especially in teenagers. The loss of young person by accident is great loss for family, society and economy of nation. No one will doubt the effectiveness of helmet on reduced incidence of head injuries. And multiple studies from United States of America have clearly demonstrated the benefit of helmets in motorcycle accidents. The following study was undertaken to determine the relationship between head injuries and helmet use in motorcycle accident, as well as analysis of general motorcycle accident.

Chronic cavities of the dorsum of the foot often have bare bone and are unsuitable for free skin grafting. Local Flaps are often impossible because of surrounding scar tissue and dead space. A simple method is presented; it consists of the excision of the lesion, filling the cavity by a two staged random-pattern de-epithelialised turn over flap, and skin graft.

Between 1989 and 1993, 31 patients who had undergone ACL reconstruction using autogenous patellar bone-tendon-bone were studied to evaluate the effects on knee joint function. After having harvested the central one third of the patellar tendon, it was positioned isometrically through tunnels of tibia and femur and also central defect of the patellar ligament was sutured loosely. Clinically Hospital for special surgery(HSS) knee socre by Marshall 1997, manual knee test, knee extention and flexion angles, Cybex test, KT-2000 measurments and radiological study were performed for subjective and objective symptoms at the average follow-up 33 months (range 18-72 months). Quadriceps weakness of strength less than 80% of the normal side was present in 61% of patients, patellofemoral joint pain in 15%, AP translation more than 3mm in 23%, flexion contracture of 5 degree or more in 29%. Hospital for special surgery(HSS) knee score was improved from 35 to 46 in average during follow-up period. The height of the patella was increased in 2 cases and decreased in 6 cases within normal variation which was not significant statistically. The above results indicate that importance of postoperative rehabilitation program and extension position of knee joint after surgery place a major emphasis on the avoidance of flexion contracture and on the improvement of joint function.
