Fifty-three Hong Kong Chinese patients with fractures of the proximal femur have been studied after hip surgery using functional ascending phlebograms for evaluating deep vein thrombosis. There was an incidence of deep vein thrombosis of 53.1 per cent in the fractured limbs and 14.3 per cent in the uninjured limbs. The majority of thrombi (84.6 per cent)(More)
An ultrasound of the neck (SSH-140 A, Toshiba, Japan) was performed followed by CT scan (Somatom CR, Siemens, Erlangen). On sonography we noticed a hypoechoic linear area extending from the neck into the superior mediastinum. It was present between the internal jugular vein and the carotid vessels in the neck and was posteromedial to the sternocleidomastoid(More)
Ninety-seven patients who underwent anterior interbody fusion for lumbar disc derangement were examined two to 15 years after the operation. Complete relief of back pain was obtained in 60% and of sciatica in 85%; marked improvement of back pain was obtained in 29% and of sciatica in 10%. The fusion rate was 63% and was only slightly correlated with(More)
We reviewed the cases of 110 patients with paralytic scoliosis due to poliomyelitis who were operated on. In the lumbar region, anterior Dwyer instrumentation with posterior fusion gave excellent correction of scoliosis and pelvic obliquity. In the more rigid thoracic curves, combined anterior Dwyer instrumentation and posterior fusion gave better results(More)
A prospective study on fact embolism showed that of ninety-five patients with a fractured shaft of the femur, seven (7 percent) demonstrated both pulmonary and cerebral disturbances, while there were profound disturbances in arterial PO2, hemoglobin level, pulse rate, and temperature in about 40 per cent of the patients. Using a modified Gurd test, a(More)
