Supracondylar fractures of the femur following total knee arthroplasty are rare complication with reported rates ranging from 0.3% to 2.5%. Union of the fracture in proper alignment, without disruption of prosthetic component fixation and with maintenance of 90 of knee motion, is impotant in treatment of this type of fracture. Modalties of treatment are conservative or operative methods and operative treatment are open reduction 4 internal fixation, intramedullary nailing, revision arthroplasty using a prosthesis with a long stem and closed reduction and external fixation, but there are controversies in the method of treatment. Between Apr. 1989 and Jul. 1994, 10 patients were treated for supracondylar fracture of the ipsilaterai femur following total knee atthroplasty and 2 cases of them had arthrop]asty at other hospital. Average age of patients was 53 years (29-68 years), nine patients were women and one was man. The preoperative diagnosis was rheumatoid arthritis in four, degenerative osteoaithritis in three, posttraumatic osteoarthritis in one and tuberculosis sequelae of the knee in two. In nine cases mechanism of injury were slip down and in one was fall down. The interval hetween arthroplasty and fracture was an average of 22 months (9-79months). Two cases we.re treated with closed reduction and cast immobilization, one case was treated with open eduction and in1ernal fixation and seven patients of' ten cases were treated with closed intramedullay Ender nailing. The average foIlow-up period after fracture was 25 months (3 - 74months). We evaluated the results as the range of motion, bony union at simple radiograph and Knee Rating Score of Hospital for Special Surgery at last follow up. Eight cases of supracondylar fracture occuned among 350 patients, 514 cases of total knee arthroplasty which were operated at Kyung Hee Univcrsity Hospital between Apr. 1989 and Jul. 1994 and incidence was 1.6%. At the last follow up, all 10 cases achieved bony union and 7 cases using Ender naiIing achieved clinical bony union which enabled patients to do weight-bearing without pain at postoperative 6-8 weeks and radiological union was achieved at postoperative 12 weeks. Range of motion were average 105 degrees (80 J.20 degrees) hefore fracture and 86 degrees (6S 120 degrees) at the last follow up and HSS Knee rating score were average 80.3 points (59 94 points) before fracture and average 78.8 points (66-89 points) at the last follow up. At 7 cases using Ender nailing, range of motion were average 106 degrees (90 11S degrees) hefore fracture and 91 degrees (6S-105 degrees) at last follow up and HSS Knee rating score were average 80.6 points (59-94 points) before fracture and average 80.3 points (72-89 poiints) at the last follow up. Closed iintramedullary Ender nailing is a gecommendable operative method in the treatment of supracondylar fracture following total knee arthroplasty considering to good bony union, satisfactory functional result, easy operative technique and less postoperative complication.

OBJECTIVE: This retrospective study presents our experience with respect to the clinical and angiographic outcomes of patients treated with stent-assisted coil embolization using Solitaire(TM) AB stents. MATERIALS AND METHODS: From March 2011 to December 2014, 50 patients with 55 wide-necked and/or complex intracranial aneurysms were evaluated. Four patients presented with an acute subarachnoid hemorrhage. Stent deployment was performed with a standard coiling procedure in 49 aneurysms. Three patients underwent bailout stenting, 2 patients were treated by temporary stenting and one patient was treated only by stenting without coiling for dissecting aneurysm. RESULTS: Successful placement of the Solitaire AB stent was achieved in all the cases. Based on the postprocedural angiographic results, a Raymond 1 was obtained in 32 (59%) of 54 aneurysms, excluded by one case of dissecting aneurysm, and a Raymond 2 in 13 (24%), and a Raymond 3 in 9 (17%). There was one thromboembolic (2%) and three hemorrhagic complications (6%). However, procedure-related morbidity or mortality was not found. Annual follow-up angiographic results from the embolization were obtained in 40 (74.1%) of 54 cases. These results were represented as Raymond 1 in 27 (67.5%), class 2 in 9 (22.5%), and class 3 in 4 (10%) cases. Angiographic improvement associated with progressive thrombosis of the aneurysm was obtained in 10 aneurysms. Four aneurysms were recanalized without requiring additional treatment. In-stent stenosis was found in one aneurysm, but stent migration was not seen on follow-up angiography. CONCLUSION: Stent-assisted coil embolization using the Solitaire AB stent for treating wide-necked and/or complex intracranial aneurysms was found to be safe and effective immediately post-embolization and after follow-up. Long-term follow-up will be required to identify the effect of the Solitaire AB stent on recanalization rates.

The widespread use of diagnostic radiography, especially using magnetic resonance imaging, has helped to increase the diagnosis of paralabral cysts in patients with chronic shoulder pain. These paralabral cysts are frequent in the anterior, the superior, and the posterior compartment of the shoulder joint but are rare in the inferior compartment. Paralabral cysts in the shoulder appear particularly in men in their third and fourth decades but rarely in elderly patients. We report a case of an inferior paralabral cyst in an elderly patient whom we treated through arthroscopic decompression.

PURPOSE: Most men with benign prostatic hyperplasia (BPH) have bothersome lower urinary tract symptoms (LUTS). This study aimed to investigate the safety and efficacy of high-performance system (HPS) laser photoselective vaporization of the prostate (PVP) for the treatment of BPH in men with detrusor underactivity (DU). MATERIALS AND METHODS: From March 2009, 371 patients with BPH were divided into 2 groups according to the findings of preoperative urodynamic study: 239 (64.4%) patients with bladder outlet obstruction (BOO) and 132 (35.6%) patients with bladder outlet obstruction with detrusor underactivity (BOO+DU). 120 W HPS laser PVP was performed to resolve the BOO. The perioperative data and postoperative results at 1 month and 12 months, including the International Prostate Symptom Score (IPSS), maximum urinary flow (Qmax), and postvoid residual urine (PVR) values, were evaluated. RESULTS: Compared with the preoperative parameters, significant improvements in IPSS, Qmax, and PVR were observed in each group at 1 and 12 months after the operation. In addition, IPSS, Qmax, and PVR were not significantly different between the BOO and BOO+DU groups at 1 and 12 months after the operation. CONCLUSIONS: Surgery to relieve BOO in the patients with BPH seems to be an appropriate treatment modality regardless of the existence of DU.

PURPOSE: To assess the diagnostic usefulness of multimodality study in the diagnosis of breast cancer. MATERIALS AND METHODS: Eighty-one patients between January 1998 to December 1999 were involved in this study, and who underwent mammography, breast ultrasonography, and 99mTc-MIBI scintimammography in all cases the findings were retrospectively reviewed. Each modality was graded by two physicians specializing in nuclear medicine and two radiologists, all unaware of the pathologic results. A four-grade system(1=definitely benign, 2=probably benign, 3=probably malignant, 4=definitely malignant) was applied to those ofbreast ultrasonography and 99m Tc-MIBI scintimammography and BIRADS was applied to those ofmammography. All breast masses were confirmed by surgery (n=67) or FNA (n=14). Findings of grade 3 or 4 the four-grade system, BIRADS category 4 or 5, or positive coincidence in double and triple combination studies were defined as positive results, and on the basis of the data thus obtained, the sensitivity, specificity, positive and negative predictive value and diagnostic accuracy were calculated for each modality and for multimodality studies. RESULTS: The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 99mTc-MIBI scintimammography were 83.6%, 88.5%, 93.9%, 71.9% and 85.2%, respectively. For ultrasonography, the corresponding figure were 94.5%, 65.3%, 85.2%, 85.0%, and 85.2%, and these for mammography, they were 87.3%, 69.2%, 87.3%, 81.8% and 80.2%. For the ultrasonography and mammography combination, the figures were 83.6%, 50.0%, 93.9%, 100.0% and 95.2%, respectively, and for 99mTc-MIBI scinti-mammography and mammography, the corresponding findings were 72.7%, 69.2%, 95.2%, 100.0% and 96.7%. For the 99mTc-MIBI scintimammography and ultrasonography combination, respective findings of were 80.0%, 61.5%, 95.7%, 94.1% and 95.2%, respectively, and in the triple modality study, respective findings of 70.9%, 50.0%, 97.5%, 100.0% and 98.1% were recorded. CONCLUSION: Among multimodality studies, sensitivity was greatest in the ultrasonography and mammography combination, which is thus extremely suitable for the diagnosis of breast cancer. The findings of two series suggest that in equivocal cases, 99mTc-MIBI scintimammography with its higher specificity and positive predictive value, is a useful adjunctive tool.
