Polydactyly is one of the most common congenital anomalies of the limb, however its surgical treatment varies from simple excision to reconstruction. The purpose of this study is to present out classification of polydactyly in which the type of surgery was concerned primarily. Two hundred and thirty five digits(134 fingers and 101 toes) in 188 patients were operated from 1980 to 1992. We divided the polydactyly into two types-the simple type, in which the extradigit arises from only one digit, and the complex type in which the extradigit connects more than two adjacent main digits. The simple type was subdivided into joint type(type I), in that the extradigit has its own joint in its origine; epiphyseal type(type II), the extradigit share common epiphysis with main digit; and hypoplastic type(type III), the extradigit is connected only by soft tissue to the main digit. The epiphyseal type(type II) was further divided into subtype A(type IIA), in that the origin seems to be directly derived from the epiphysis; and subtype B(type IIB), which resemble an osteochondroma. Type III and type IIB can be treated by simple excision, however the type I and type IIB can be treated by arthroplasty with or without osteotomy as well as excision of extradigit. Result of surgical treatment in 1 digit of the simple form, which siginifies the extradigit arising from only one digit, are good in 193 digits(91%), fair 14(6.6%), and poor 5(2.4%) after an average follow-up period of 20 months. Our principles in the surgical treatment of polydactyly was treatment according to the type, and early treatment.

Between 1984 and 1996, 8 patients who were suffered from stage g Kienbock's disease underwent interpositional arthroplasty using pronator quadratus pedicled bone. Patients comprised 2 males and 6 females, with an average age of 33 years(range 19-47). Range of motion of the wrist, residual pain, grip strength, and carpal height ratio of the patients were analyzed. The follow-up period was between 1.5 years and 12.5 years(average 5.5 years). The arc of flexion-extension of the wrist was increased from average 74 degrees preoperatively to 96 degrees postoperatively. Among eight patients, five were free of pain and three had intermittent pain during heavy work. None of eight patients had any discomfort in daily work and changed his or her occupation. The grip strength was average 83% of the normal side. Carpal height ratio was average 0.48 preoperatively and was not changed postoperatively. Clinical results, assessed by Lichtman-Evans criteria, showed 4 good and 4 fair. The interpositional arthroplasty using pronator quadratus pedicled bone was considered as a very effective method for the treatment of stage III Kienbock's disease.

Toward the beginning of the twenty-first century, the world experiences the dramatic changes in politics, economics and culture, and it is evident that the Korean medical field will not be able to survive provided it doesn't prepare ourselves to adapt to those changes. The Korean Medical Society held a forum for the active operation of the medical society, inviting several leading affiliated societies, to meet the needs of the times. This review describes the summary of the presentation that the authors made on behalf of the Korean Radiological Society in the forum, including the organization, current status of academic activity, current status of international communication, and problems encountered in the internationalization of the Korean Radiological Society.

Radilogic findings in 30 patients with intestinal tubeculosis and 10 patients with intestinal Behcet'sdiseases, who had been diagnosed at seoul National University Hospital during the recent 5 years, were analysedretrospectively to evaluate the radiologic differential diagnosis of the two diseases. Intestinal tuberculosisseverely involved the cecum, the ileocecal valve, the distal ileum and colons, but Behcet's disease mainlyinvolved th distal ileum and infrequently the ileocecal valve and the cecum. The ulcers in tuberculosis wereusually multiple small barium collected areas among psuedopolyps on the contrary, those in Behcet's disease weremultiple, discrete, well marginated, geographic, ring-like deep penetrating or collar-button shaped. Intestinaltuberculosis tended to involved long segments of intestines, with severer mucosal irregularity and deformity ofthe ileocecal valve and the ascending colon in comparison with Behcet's disease. Mesenteric and/or peritonealinvolvment were accompanied in 1/3 cases of intestinal tuberculosis,a nd active pulmonary tuberculosis or pleuraleffusion also in 1/3 cases of intestinal tuberculosis.

Differential diagnosis of vertebral lesion by simple radiography is not so easy whether the lesion is benign or malignant. The purpose of this study is to evaluate that the magnetic resonance imaging characteristics can differentiate benign or malignant vertebral lesions. In this study, thirty-nine cases of signal change within the vertebral body by MRI was reviewed retrospectively and the followings are the summary of the results. It is difficult to differenciate benign or malignant lesions, only based on MRI signal changes or vertebral lesion patterns. But those cases of pedicle involvement, complete replacement of bone marrow in T1image and associated soft tissue mass or cord compression are strongly suggest the possibility of malignancy and need further study.
