RESUMEN
PURPOSE: To evaluate the usefulness of a 2 holes side plate dynamic hip screw for the treatment of stable intertrochanteric fracture of the femur. MATERIALS AND METHODS: Between January 2000 and September 2004, 46 patients with intertrochanteric fracture of the femur were treated with 2 hole side plate dynamic hip screw (Group 1, 25 cases) or 4 hole side plate dynamic hip screw (Group 2, 21 cases). The mean age of the patient was 70 years, with a mean follow-up duration of 13 months. The time for operation, surgical incision length, blood loss, time for union, the sliding distance, change in the femoral neck-shaft angle and patient's walking ability were evaluated. RESULTS: The mean operation time and mean incision length were shortened, and mean blood loss was decreased in Group 1 (p<0.01). There was no statistical difference in the union time, the mean change in the femoral neck-shaft angle and the mean sliding distance of the lag screw at the last follow-up. The mean mobility score of the Parker and Palmer was 8.0 points before the fracture and 7.2 points at the last follow-up. CONCLUSION: Two-hole side plate dynamic hip screw is a useful device, in terms of the operation time, morbidity of operation site, satisfactory union rate and functional recovery of the patient in treatment of elderly patients with stable intertrochanteric fractures of the femur.

BACKGROUND: Positron emission tomography(PEFT) using fluorine-18 deoxyglucose(FDG), showing increased FDG uptake and retention in malignant cells, has been proven to be useful in differentiating malignant from benign tissues. We indertook the prospective study to compare the accuracy of the whole-body FDG PET with that of the conventional chest computed tomography(CT) for nodal staging of non-small-cell lung cancers(NSCLC). MATERIAL AND METHOD: FDG PET and contrast enhanced CT were performed in 36 patients with potentially resectable NSCLC. Each Imaging study was evaluated independently, and nodal stations were localized according to the AJCC regional lymph nodes mapping system. Extensive lymph node dissection(1101 nodes) of ipsi- and contralateral mediastinal nodal stations was performed at thoracotomy and/or mediastinoscopy. Image findings were compared with the histopathologic staging results and were analyzed with the McNema test(p) and Kappa value(k). RESULT: The sensitivity, specificity, positive predictive value, and negative predictive value of CT for ipsilateral mediastinal nodal staging were 38%, 68%, 25%, 79%, and 61%, and those of PET were 88%, 71%, 47%, 95%, and 75%(p>0.05, K=0.29). When analyzed by individual nodal group(superior, aortopulmonary window, and inferior), the sensitivity, specificity, positive predictive value, and negative predictive value of CT were 27%, 82%, 22%, 85%, and 73%, and those of PET were 60%, 87%, 92%, and 82%(p<0.05, k=0.27). CONCLUSION: FDG PET in addition to CT appears to be superior to CT alone for mediastinal staging of non-small cell lung cancers.
