Background:Ultrasonography is accepted as a useful imaging modality in the early detection of developmental dysplasia of the hip (DDH). Early detection and early treatment of DDH prevents hip dislocation and related physical, social, economic, and psychological problems. The purpose of this study was to evaluate the reliability of ultrasonographic and roentgenographic measurements measured by seven different observers.Materials and Methods:The alpha angles of 66 hips in 33 patients were measured using the Graf method by seven different observers. Acetabular index degrees on plane roentgenograms were measured in order to assess the correlation between the ultrasonographic alpha angle and the radiographic acetabular index, which both show the bony acetabular depth, retrospectively.Results:The interclass correlation coefficient, measuring the interobserver reliability, was high and statistically significant for the ultrasonographic measurements. There was a negative correlation between the alpha angle and the acetabular index.Conclusions:Ultrasonography, when applied properly, is a reliable technique between different observers, in the diagnosis and follow up of DDH. When assessed concomitantly with the roentgenographic measurements, the results are reliable and statistically meaningful.
We present a large scale database of images and captions, designed for supporting research on how to use captioned images from the Web for training visual classifiers. It consists of more than 125,000 images of celebrities from different fields downloaded from the Web. Each image is associated to its original text caption, extracted from the html page the image comes from. We coin it FAN-Large, for Face And Names Large scale database. Its size and deliberate high level of noise makes it to our knowledge the largest and most realistic database supporting this type of research. The dataset and its annotations are publicly available and can be obtained from http://www.vision. ee.ethz.ch/~calvin/fanlarge/. We report results on a thorough assessment of FAN-Large using several existing approaches for name-face association, and present and evaluate new contextual features derived from the caption. Our findings provide important cues on the strengths and limitations of existing approaches.
Thromboprophylaxis following arthroscopic knee surgery (AKS) is not clear in the literature. The purpose of this study was to present the incidence of symptomatic deep vein thrombosis (DVT) following elective AKS over the age of 40. The secondary purpose was to investigate risk factors associated with venous thromboembolic events (VTEs). Surgical database and outpatient clinic follow-up charts of the patients who underwent AKS for any reason were included in the study. Odds for risk factors such as previous medical history of thrombosis, any family history for clotting disorders, diabetes mellitus (DM), oral contraceptive usage, body mass index, history of malignancy, and smoking were evaluated. The incidence of DVT following AKS significantly increased in the patients older than 40 years who had a previous medical history of VTE, DM, and smoking. A variety of guidelines exist for VTE prophylaxis; however, one should focus on risk factors related to the patient’s medical history and current medical conditions. In this study, smoking, DM, and previous history of DVT increased DVT risk significantly, and thromboprophylaxis should be kept in mind for these patients.
The most important causes of anterior knee pain include patellofemoral malalignment which causes patella-condyle contact anomalies at the patellofemoral joint, excessive patellar lateral pressure increase, trauma and overuse. In this article, besides presentation of late clinical results of 169 lateral retinacular release cases which were surgically treated between January 1995 and December 2002 with the help of a hook knife from the anterolateral portal due to lateral compression syndrome and patellar maltracking, we also described quadriceps tendon pressure-pull test which strongly indicates patellofemoral pain during physical examination of a patient with anterior knee pain. In addition to radiological patellofemoral imaging methods, we describe dynamic arthroscopic patellofemoral joint examination which is applied perarthroscopically to all of our surgically treated patients. We divided the patients into two groups: group 1 was the younger group with age 16-40 years; group 2 was the older group with age >41 years. Preoperative mean Lysholm scores for group I was 67.6 and 98.6, postoperatively, whereas it was 62.3 preoperatively and 91.4 postoperatively in group 2. This improvement of Lysholm scores postoperatively was statistically significant for each of the two groups (p=0.001). For group 1 preoperative IKDC scores were A in 8 patients, B in 61 patients and C in 11 patients, whereas it was A in 78 patients and B in 2 patients postoperatively. For group 2 preoperative IKDC scores were A in 2 patients, B in 43 patients, C in 36 patients and D in 8 patients, whereas it was A in 78 patients and B in 11 patients. This improvement of IKDC scores postoperatively was also statistically significant for each of the two groups (p=0.001). Preoperative and postoperative congruent angles of all patients were also measured. Preoperative mean congruent angle was +16.4 in group 1 while mean congruent angle was -7.1 postoperatively. For group 2 preoperative mean congruent angle was +18.7 preoperatively and -6.9 postoperatively. This improvement was statistically significant for each of the two groups (p=0.001). The overall number of patellar lateral compression syndrome cases were 51 (24 in group 1, 27 in group 2), patellar lateralization cases were 64 (28 in group 1, 36 in group 2) and patellar subluxation cases were 54 (28 in group 1, 26 in group 2). At the evaluation of arthroscopic lateral patellar facet and lateral femoral condylar chondral pathologies, we statistically showed that patellar chondral pathologies were more severe than the femoral chondral pathologies (p=0.001). In our opinion, the severity of patellar lateral facet chondral lesions, although it has a thicker layer of cartilage, is due to distribution of load to a larger contact area of lateral femoral condyle. Statistically increasing severity of femoral (Kendall's tau-b: 0.248, p=0.001) and patellar chondral lesions (Kendall's tau-b: 0.444, p=0.0001) with age is compatible with our arthroscopic and clinical observations. The most important complication s...
Background. The aim of the study is to analyze the major agricultural injuries related to the extremities. Patients. We evaluated a 3-year period including 41 patients. Data on age, sex, injury patterns, anatomical localizations, injury season, length of stay in the hospital, and infections were evaluated, and the patients were examined with SF-36 in the follow-up period. Results. Hand was the most commonly injured part (n: 9) followed by the distal part of the lower limb (cruris) (n: 7) and foot (n: 7). Mean time between trauma and emergency-department arrival was 115 minutes (60–360). Mean length of stay was 24 days (4–150), and mean number of operations during hospitalization was 2.4 (1–30). Deep wound infection was seen in 8 patients. Seasonal distribution for accidents was even for spring and fall (27% each), high for summer (36%), and less for winter (10%). Conclusions. Distal parts of the elbow and knee were affected more frequently. Due to the high microbiological load and high incidence of crush-type injuries, repetitive debridements and long duration of hospital stay were needed. Attention should be paid in the harvesting times to the farmyard injuries. Due to the seasonal variation, more resources should be allocated to treat the increasing incidence of injury over the period from spring to fall.
Scapular spine fractures are rare injuries. The aim of this study was to evaluate a late-diagnosed scapular spine pseudo-arthrotic patient. Because of the surrounding soft tissue mass and overlapping of the scapula with the thoracal bones on a roentgenogram, diagnosis may be missed or delayed for years. We present a case of scapular spine pseudo-arthrosis in a 50-year-old man, who sustained a traffic accident 2 years ago. He was treated as a soft tissue injury of the left shoulder and later as a rotator cuff tear. His scapular spine fracture was diagnosed as pseudo-arthrosis of the scapular spine with a diagnostic delay of 2 years. Isolated scapular spine fractures are rare, usually associated with other injuries and frequently treated non-operatively. Sagging of the acromion as a result of a scapular spine fracture may mimic supraspinatus outlet impingement. If a painful pseudo-arthrosis limits the function of a shoulder, fractured ends should be fixed until union occurs. Although scapular spine fractures are rarely seen, they must take place in the differential diagnosis of impingement syndromes of the shoulder.
