Although intramedullary nailing is mostly used in the management of fractures in the long bone shaft, plate fixation is still alternative option in periprosthetic or metaphyseal fractures. For the rigid fixation during plating, sometimes we need wiring. Many surgeons experience slippage of wire resulting in loss of rigid fixation because plate and wire is so slippery and the diameter of bone is changing by level especially in the metaphyseal area. Wiring plate(CHO plate) was designed to prevent slippage. This plate has transverse holes for wires between screw holes on traditionally used dynamic compression plate. Sixteen fractures of long bone shaft were fixed with wiring plate and 11 cases which were followed up for more than one year were evaluated. There were periprosthetic fractures(4 cases), spiral or butterfly fractures(4 cases) and fractures of poor bone quality(two cases of malignancy and one case of osteoporosis). Nine cases were successfully reduced and the healed without loss of fixation. In two cases, delayed union and nonunion were observed due to wire breakage with plate loosening. Preliminarily, wiring plate fixation can be used for the periprosthetic fracture and one of alternative option in butterfly or spiral fracture and fracture in osteoporotic bone or pathologic fracture.

Spontaneous rupture of the kidney is rare. It usually occurs secondary to various kinds of underlying disease such as infection, hydronephrosis, calculous disease, benign or malignant tumor, renal artery aneurysm and arteriosclerosis. In most instances, it is an acute abdominal process which requires early diagnosis and immediate surgical exploration. We report a case of spontaneous rupture of the kidney secondary to renal cell carcinoma in a 44 year-old female.

BACKGROUND: There is a clinical need for a simpler measurement of global cardiac function incorporating elements of both systole and diastole. Doppler time index is theoretically regarded as a sensitive index of global left ventricular perfomance and defined as the sum of isovolumetric contraction time (IVCT) and isovolumetric relaxation time (IVRT) divided by ejection time (ET). This study was designed to determine the clinical usefulness of the Doppler time index in patients with left ventricular diastolic dysfunction as well as systolic dysfunction. METHODS: The study population consisted of 23 patients with hypertension as a diastolic dysfunction group, 16 patients with low ejection fraction as a systolic dysfunction group and 31 subjects with normal LV function. The ejection fraction (EF) was measured using M-mode echocardiography. Doppler profiles such as IVCT, IVRT and ET were obtained from Doppler echocardiography. The Doppler time index [ (IVCT+RT)/ET] was calculated from each Doppler velocity profiles. RESULTS: IVRT, IVRT/ET and (IVCT+VRT)/ET were significantly increased in the diastolic dysfunction group (120.5+/-19.5 msec, 0.45+/-0.1, 0.64+/-0.2, respectively:p<0.001, p<0.001, p<0.001, respectively) compared with normal subjects (66.1+/-17.4 msec, 0.25+/-0.0, 0.41+/-0.1). IVCT and IVRT were significantly increased and ET was significantly shortened in systolic dysfunction group (75.4+/-25.7, 144.0+/-39.5 msec, 242.7+/-46.5 msec respectively:p<0.001, p<0.05, p<0.05, respectively) compared with diastolic dysfunction group (50.4+/-23.0 msec, 120.5+/-19.5 msec, 276.8+/-44.6 msec, respectively). IVCT/ET, IVRT/ET and (IVCT+IVRT)/ET also were increased in patients with systolic dysfunction group (0.32+/-0.1, 0.61+/-0.2, 0.93+/-0.2 respectively:p<0.01, p<0.01, p<0.001, res-pectively) compared with diastolic dysfunction group (0.19+/-0.1, 0.45+/-0.1, 0.64+/-0.2). Ejection fraction calculated by M-mode parameters was significantly correlated with (IVCT+IVRT)/ET (correlation coefficient - 0.605, p<0.001). CONCLUSION: The Doppler time index was significantly difficient from normal subjects in patients with isolated LV diastolic dysfunction as well as in those with systolic dysfunction. Thus, this index can be used as a sensitive indicator of myocardial performance.

PURPOSE: To assess the arthroscopic findings in chronic lateral ankle instability and to evaluate the results of modified Brostrom operation and arthroscopic procedures. MATERIALS AND METHODS: Twenty-nine cases with chronic lateral ankle instability were treated with modified Brostrom operation and ankle arthroscopy from May 2004 to January 2007. There were 19 male and 10 female with the mean age of 29.7 years. Mean follow up period was 15.8 months. All patients were checked preoperative stress anterior drawer and varus test with X-ray. RESULTS: Associated injuries were 28 fat impingement projected into the joint between distal tibio-fibular space, 20 anterior impingement of soft tissue, 19 osteochondral defects and 13 loose body. Preoperative AOFAS score of pain, function and alignment were 28.9, 34.1 and 7.9 each other. They were improved into 38.7, 40.8 and 9.8 postoperatively. CONCLUSIONS: Modified Brostrom operation with ankle arthroscopy for chronic lateral ankle instability is believed to be a reliable option to obtain satisfactory results. Careful attention to the associated injuries such as distal fat impingement, anterior impingement, osteochondral defect and loose body is needed during the arthroscopy.

Carcinomas derived from ameloblastomas have been designated by a variety of terms, including malignant ameloblastoma, ameloblastic carcinoma, metastatic ameloblastoma, and primary intra-alveolar epidermoid carcinoma. The term of ameloblastic carcinoma is differentiated from the term of malignant amelblastoma and is defined as an ameloblastoma in which there is histologic evidence of malignancy in the primary tumor or the recurrent tumor(or metastasis), regardless of whether it has metastasized. The well-documented and adequately followed cases are currently lacking and this report described an instance of ameloblastic carcinoma with good result after treatment and review of literature.

STUDY DESIGN: This is a prospective study. OBJECTIVES: We wanted to analyse the correlation between the radiographic and clinical results after anterior cervical discectomy and fusion (ACDF) for treating degenerative cervical diseases. Summary of Literature REVIEW: ACDF is a successful procedure for treating the degenerative cervical spine. Many studies have reported on radiographic results and clinical outcomes of this procedure. However, few studies have examined the relationships between the changes of the radiographic parameters and the clinical results after ACDF. MATERIALS AND METHODS: 26 patients who had single level ACDF performed for degenerative cervical diseases during the period between Jan, 2000 and Dec, 2004 were evaluated. All the patients underwent autologous iliac bone graft and plate fixation. The radiographic parameters, including the disc height, the disc space angulation and the spinous process distance were measured at the preoperative period, post operative 1 month and the last follow up period, respectively. The clinical changes were measured using the visual analogue scale (VAS) for neck and arm pain at the preoperative and last follow up period. The correlations between the radiographic parameters and the clinical outcomes were assessed by Pearson correlation. RESULTS: There were significant changes in disc height (6.7-7.9 mm) as well as disc space angulation (kyphosis: 1.1degrees, lordosis: 3.4degrees). The reduction in the neck pain VAS score (63.9-33.1) and the arm pain VAS score (57.9-29.7) was significant. None of the correlations between the radiographic parameters and the clinical outcomes were significant (p>0.05). CONCLUSION: Although the clinical outcomes improved significantly, there was no significant correlation between the radiographic parameters and clinical results after performing single level anterior cervical discectomy and fusion for the degenerative cervical disease.
