The QRS loop on the horizontal plane of the vectorcardiogram and the QRS complex in the right praecordial leads of the electrocardiogram were studied in 8o patients with strictly posterior and/or lateral infarction. In all 30 patients with combined posterolateral infarction a ratio RIS greater than I in lead Vi was found. In I9 out of the 23 patients with strictly posterior infarction and in al...

A 33-year-old Caucasian woman came to our attention complaining of lateral knee pain on the left side, severe external instability associated with varus malalignment, and difficulties in weight-bearing activities. The symptoms had appeared following two lateral meniscectomies on her discoid meniscus, performed elsewhere. The patient was initially submitted to an allograft meniscus transplantati...

–Technological advances and developments in solar activities, particularly in solar radio bursts, have created a demand of constructing log periodic dipole antenna (LPDA) to monitor this phenomenon in radio region. In this paper, we make an effort in designing a portable LPDA that suitable with the criteria, specification and practical enough although is the boom length size of the antenna is 3...

The authors discuss their recent experience with anteriorly located C1-C2 neurofibromata in five patients with cervical myelopathy and magnetic resonance scans consistent with intradural extramedullary masses in this region. Surgery was performed using a posterolateral approach with microscopic intradural exploration. Gross total intradural tumor removal was achieved in all cases. Improvement i...

Acute posterolateral corner injuries of the knee are rare and, when present, are frequently associated with concurrent ligament injury, neurovascular damage, or fractures of the femur or tibia. Early surgical treatment has been shown to be superior to delayed and nonoperative treatment of multiligamentous knee injuries. Historically, repair has been advocated. High-quality studies comparing rep...

Herein, we present the case of a 45-year-old woman with pulsion and midesophageal diverticula, who had complaints of dysphagia and regurgitation. Diagnosis was confirmed by endoscopy and barium swallow. The patient underwent right posterolateral thoracotomy with excision of diverticula and repair of the muscular layer along the site of diverticula. Five days following the operation, barium swal...

A 74-year old patient underwent aortic valve replacement and mitral annuloplasty (Edwards Lifesciences Physioring, 34 mm). Five weeks post-surgery, he was readmitted because of heart failure due to a severe residual mitral regurgitation. Three-dimensional (3D) echocardiography clearly demonstrated the posterolateral area of dehiscence. He underwent successful surgical refixation (Fig. 1 and Sup...

While injury to the posterolateral corner is accepted as a relatively common occurrence associated with rupture of the anterior cruciate ligament, posteromedial meniscocapsular injury has not previously been recognised as such. In a prospective assessment of 183 consecutive reconstructions of the anterior cruciate ligament this injury was observed in 17 cases, giving it an incidence of 9.3%. Cl...

We dissected 21 cadaver elbows to determine the relationship of the posterior interosseous nerve to the posterolateral approach to the elbow and head of the radius. At the distal end of the exposure the first branches at risk, those to extensor carpi ulnaris, were on average 6.0 +/- 1.0 cm (4.0 to 8.4) from the articular surface of the radial head. When using the posterolateral approach it is i...
