Distal radial fractures are recognized as very complex injuries with a variable prognosis that depends upon the fracture type and the treatment method. The purpose of this study is to compare radiological and clinical result between external fixation and external fixation with primary bone graft in intraarticular comminuted fracture of distal radius. From January 1993 to December 1995, 32 patients with comminuted intraarticular fractures of the distal radius were treated using a external fixation. 15 cases were treated with ligamentotaxis without bone graft and 17 cases were treated with additional primary bone graft. In last follow-up examination, the mean loss of radial length, radial inclination and volar tilt were less in with bone graft group than without bone graft group. According to Demerit point system Excellent to good results were obtained in 88.2% in cases of external fixation and bone graft group, 66.6% in cases of only extemal fixation group. External fixation combined with primary bone graft is more useful method for the reconstruction and treatment of comminuted intraarticular fractures of the distal radius than closed reduction and external fixation because cancellous bone graft not only provides early mechanical stability but also helps to reduce and supports the depressed intraarticular fragments. Furthermore, this method not only prevents late collapse of fracture but also enhance fracture healing.

3.Orthogonal versus Parallel Plating for Distal Humeral Fractures.
Clinics in Shoulder and Elbow 2015;18(2):105-112
In orthopedic trauma surgery, treatment of intraarticular distal humerus fractures is a challenge. With development of implants and biomechanical studies, surgical strategies with recommendations including preoperative computed tomography images, proper approaches and open reduction and internal fixation with dual plates have emerged. In addition, as an effort to provide stable fixation to permit early elbow motion, different methods of internal fixation, particularly plate configuration, have evolved. Using dual plates, either oriented parallel to each other or orthogonal, stable fixation has been achieved and satisfactory clinical outcomes have been reported. With rationales and advantages/disadvantages of each plate configuration, both techniques are selected according to surgeons' preference, and, in specific cases, one could be preferred over another. The key to successful fixation by either technique is obtaining anatomical reduction with restoration of two stable columns of the distal humerus.

4.Treatment and Clinical Application Of a Triangular Splint Method for Fracture of the Humerus
The Journal of the Korean Orthopaedic Association 1978;13(3):425-431
Fracture of the shaft of the humerus had been treated by many different way, such as hanging cast, shoulder spica cast, abduction splint, and Velpeau bandage, etc, The authors have employed the new trianglar splint designed by ourselves for the 54 cases of fracture of the humeral shaft from Jan., 1965 to Oct., 1976 in the department of Orthopedic surgery of Han-il Hospital. In our experience, the triangular splint method is useful for not only fracture between the head of the humerus and supracondylar region, but also shoulder joint injuries and diseases which need firm immobilization. The triangular splint method has merits, such as spontaneous reduction by the fractured arm weight with gravity, the stability during care, relatively comfort during procedure. Satisfactory results had been obtained by the triangular splint method.

Desmoplastic small round cell tumor (DSRCT) is a rare neoplasm of young adults and it is characterized by polyphenotypic differentiation. We experienced a case of abdominal DSRCT that occurred in a 19-year-old female who presented with painful swelling of her right forearm. The tumor was cytokeratin-negative and it exhibited some tumor cells with intranuclear inclusions. Molecular demonstration of EWS-WT1 fusion transcripts is particularly useful to confirm the diagnosis of DSRCT without epithelial differentiation. We report here on a case of cytokeratin-negative DSRCT that showed an unusual feature of intranuclear inclusions.

To cover soft tissue defect, various types of flaps have been used. Although lateral supramalleolar flap has been used as rotation flaps or reversed island flaps to cover defects around the foot and ankle, there has been no report about its application as a free flap. The lateral supramalleolar island flap has proves to be supplied constantly by the terminal branch of the peroneal arterys perforating branch. The free lateral supramalleolar flap has the same skin territory. Its vascular pedicle can be extended to the main peroneal artery and vena comitans, which can be obtained by dissecting the peroneal vessels between the distal tibia and fibula through the interosseous membrane. We have successfully transferred this free flap in eight patients from April 1994 to February 1995. All of the patients had full thickness skin defects which were caused by contact thermal burn, electrical burn, flame burn or traffic accident. There were no complications. From our experience, we feel that this new free flap have some advantages, induding vascular anatomy and long pedicle with large diameter and a relatively thin flap with minimal morbidity of donor site.

BACKGROUND: Along with the recent greater number of medical devices for the elderly in the market, there has been a parallel increase in the number of clinical trials for these devices. It is uncertain, though, whether the target population has the awareness and understanding of these clinical trials and the possible adverse events of the devices. METHODS: A total of 147 elderly subjects (mean age, 65.8+/-8.3 years; 39 males) responded to the questionnaire. A pilot study during the development of the questionnaire was conducted in 2009 with the actual survey taking place from June to November 2011. The questionnaire included 22 items-10 items on awareness and understanding of the clinical trial; 4 items on the understanding of adverse events; and 8 items on demographical characteristics. RESULTS: Of the responders, 62.5% had participated in at least one clinical trial and had heard about the clinical trials through a doctor, newspaper, or television. And 63.3% of the responders understood that the purpose of the trial was to show efficacy and safety for the medical device. There were significant differences on the awareness of the trial by gender and life level. However, there was no statistically significant difference in adverse events awareness. CONCLUSION: Although elderly subjects participate in clinical trials, it seems they do not receive enough information when involved in clinical trials of medical devices. In the future, before these trials are carried out, medical device companies need to ensure that they provide their elderly subjects with better education and information.
