130 cases of the suprarcondylar fractures of the humerus in children were analysed. 60 cases were immobilized with plaster splint without closed reduction. 22 cases were closedly reduced and immobilized with plaster splint. 47 cases were closedly reduced and were fixed percutaneously with K-wires. 39 cases were operatively reduced and were fixed with K-wires. The following results were obtained. 1. The average age was 7.9 years, and the male and female ratio was 2.7: 1. 2. The extension type was 96.2% and the flexion type was 3.8%. 3. The left side (64.6%) was more frequently involved. 4. As associated complications, nerve injury (4.6%), vascular injury (2.3%), open fracture (2.3%), and associated fracture (2.3%). were developed. During treatment incomplete ulnar nerve palsy (2.3%), pin tract superficial infection(3.1%), severe cubitus varus deformity(4.6%), severe limitation of elbow motion(11.6%) were also developed. 5. Final results in the Holmberg's 4 Groups according to Mitchell & Adams' criteria showed that the more the displacement of fracture is increased, the more the poor result is also increased. 6. In spite of the selection of the more severe cases for surgery, the results of the operative cases were better than those achieved by closed reduction in the easier cases. 7. In the displaced fractures, immediate open reduction brings the satisfactory results and minimizies the sequellae.

The knee joint is one of the major weight bearing joint in the body, and is frequently injured because of its complex motion despite of a simple bony architecture. In the fracture of the tibial condyle the injuries of soft tissues such as ligaments and menisci are frectuently accompanied, and the weight bearing surface is involved. So it often produces a disability of the knee joint. Forty-seven consecutive cases of the tibial condylar fracture treated at the orthopaedic department of the Hallym Medical College from 1982 to 1985 have been analyzed according to its type, radiologic diagnosis, treatment, and end results. The conclusions are; 1. The tomography is important in the decision of the treatment method by the accurate measurement of the extent of depression and displacement. 2. The poor results are usually caused by a severe comminution and some associated injuries such as menisus tear, open wound, and rupture of ligamentum patellae etc. 3. The better results can be obtained with the treatment of early exercise within 6 weeks, of weight bearing between 12-20 weeks, and in surgical cases, within 2 weeks and with a bone graft.

BACKGROUND: A point mutation in the RET proto-oncogene, in medullary thyroid carcinoma (MTC) is well known, but no other genetic causes of MTC have been found. This study was performed to identify the most common DNA copy number changes in MTC by comparative genomic hybridization (CGH). METHODS: Twenty-nine surgically resected MTC specimens were retrospectively selected from patients operated on between 1996 and 2004 at the Asan Medical Center. A review of the clinical data and pathological findings was performed. Congored staining and immunohistochemical stains (calcitonin, chromogranin A and CEA) were processed by tissue microarray. CGH analysis was performed. RESULTS: The Congo-red stain was positive in only 12 cases. The immunohistochemical results were positive in 29 cases for chromogranin A, 26 cases for CEA and 25 cases for calcitonin. DNA copy number changes were found in 23 cases (79.3%). The most frequent change was a gain of 19q (65.5%); less frequent changes were gain of 22 (55.2%), 19p (51.7%), 16p (27.58%), 17q (17.24%), and loss of 4q (27.6%) and 3p (17.24%). CONCLUSIONS: DNA copy number changes of MTC were more common (79.3%) than reported in previous studies. The most frequent changes were gains in 19q, 22 and 19p.

Eaton and Littler's ligament reconstruction is used to treat carpometacarpal instability of the thumb using the flexor carpi radialis tendon. This procedure involves a reconstruction of the deep anterior oblique ligament in patients with post-traumatic prearthritic unstable joints. According to a recent paper, the dorsoradial ligament as well as the deep anterior oblique ligament plays an important role in stabilizing the trapeziometacarpal joint. We report three cases of post-traumatic instability in a prearthritic thumb that was treated with Eaton and Littler's reconstruction using the flexor carpi radialis tendon.

PURPOSE: To evaluate the results of the treatment of the supracondylar fractures of the humerus according to the fixation methods with cannulated screw. MATERIALS AND METHODS: Eight patients, aged 49 to 82 years (average, 65 years), were reviewed after a mean follow-up of 16 months (range, 12~24 months). According to AO classification all fractures were classified as type A2 (simple transverse supracondylar fracture). All patients underwent closed reduction. Percutaneous fixation with cannulated screws was performed in 8 patients. Three of 8 patients had associated medical problems and one patient had distal radius fracture. The functional results were assessed by the Mayo Elbow Performance Score. RESULTS: Mean operation time was 59 minutes (45~75) and all the patients with cannulated screw fixation had bony union and were able to early ROM exercise. Mean ranges of motion was 5~120 degrees with excellent functional results. Functional evaluation of elbow joint by Mayo method showed mean value of 88 (75~95). CONCLUSION: The cannulated screw fixation of supracondylar fracture of humerus, especially in the elderly aged group with medical disease had excellent functional results (rigid fixation & early ROM exercise) due to shortening of surgery time and anesthesic time, combined with decreased technical difficulties of the surgical procedure
