This study investigated the clinical outcomes of fixation of displaced middle-third clavicular fractures using percutaneous elastic stable intramedullary nails. Material and methods. This study included sixty patients with a mean age of 26.40 ± 8.91 years (16-53 years) presented with a displaced middle third fracture of the clavicle. According to the Robinson classification, 48 cases (80%) were type 2B1, 9 cases (15%) type 2B2 and 3 case (5%) 2A1. All cases were treated by elastic intramedullary nails and followed up for at least 12 months. Results. At the end of the twelve months’ follow-up period, the mean Constant Shoulder score was 95.70 ± 13.55, ranging from 48 to 100. 54 patients (90%) had excellent results, 3 patients (5%) had an adequate result and 3 patients (5%) had a poor result. There was a statistically significant relationship between the final score and age and associated medical conditions. Conclusions. 1. Elastic Stable Intramedullary Nailing is an image-dependent procedure indicated best for young medically free athletes with simple 2-part middle third clavicle fracture. 2. Hammering is not recommended to avoid dorsolateral cortex perforation. 3. The most common complication is medial skin irritation because of the subcutaneous position of the clavicle as well as the sharp end of the cut nail.

Different methods have been adopted to treat delayed union and non-union of fractures of the base of the fifth metatarsal using screws, plates and tension band wires. There has been increasing use of intramedullary screw fixation to treat these fractures with variable rates of success. The optimum screw diameter and properties have been a subject of debate. To assess the results of using a larger diameter 5.5 mm cannulated, headless variable-pitch screw to fix delayed union of Jones fracture of the base of the fifth metatarsal. Methods and methods. A case series study including 24 patients with delayed union of Jones fifth metatarsal fractures. The fractures were fixed by a 5.5 mm cannulated variable-pitch compression titanium screw (Acumed® Acutrak 2® Screw System). Results. Radiological union was achieved in all patients at a mean of 7.2 weeks. At 12 months’ follow up, patients had a mean American Orthopedic Foot & Ankle Society midfoot score of 95.6. The mean Short Form 12 Physical and mental survey scores improved from 22.71 and 29.31 points preoperatively to 57.88 and 59.54 respectively. Conclusion.The headless compression screw achieved a satisfactory union rate for delayed union Lawrence zone II fractures of the base of the fifth metatarsal with satisfactory functional results.

This study examined the clinical outcomes of fixation of displaced fractures of the proximal humerus using a trans-deltoid approach. Material and methods. Twenty patients (13 male and 7 female) were treated with this technique, with a mean age of the patients of 38.85 years (range, 19 to 64 years). All patients were followed up for at least twelve months and were evaluated according to the Constant shoulder score. Results. The mean Constant Shoulder score was 87.45, ranging from 63 to 100. Ten patients (50%) had excellent results, four patients (20%) had good results, three patients (15%) had satisfactory results, and three had adequate results (15%). There was a statistically significant difference between the type of the fracture and the final score (p=0.013), where 3-part fractures with impaction (11-B1), either valgus or varus impaction, showed higher scores than those without impaction. Four patients presented with post-operative complications varying from superficial infection to radial nerve palsy. Conclusions. 1. The trans-deltoid approach was a safe and reliable alternative to the delta-pectoral approach for the treatment of displaced proximal humerus fractures. 2. The impacted (11-B1) fracture type was a significant contributing factor in terms of good functional outcomes.

The use of IVC variation is favored among the dynamic methods of fluid responsiveness assessment in the ICU because it is non-invasive and inexpensive; moreover, it does not demand a high level of training. The aim of this study is to determine the value of the IVC respiratory variability for predicting fluid responsiveness in spontaneously breathing sepsis patients with acute circulatory failure. Results In this prospective observational study, fifty-eight spontaneously breathing sepsis patients admitted in the ICU were enrolled after the approval of the departmental Research Ethical Committee, and the informed written consent had been taken from the patients. Ultrasonographic and echocardiographic parameters were measured “IVC parameters and stroke volume (SV)” with calculation of the inferior vena cava collapsibility index (IVCCI) and cardiac output. These values we...

A key component of this research was the evaluation of the different onsets detection algorithms, and their applicability to the prototype developed herein. Another focus of the research was the smoothing of the fundamental frequency estimates, produced by the YIN algorithm. As a result of the research undertaken, we have found that an onset detection method based on the estimated note changes was more robust to background noise. Our prototype is developed in Max/Msp environment, which renders our prototype open to changes by its user, and make it useful with most software midi synthesizer.
