We reviewed prospectively, after skeletal maturity, a series of 24 patients (25 hips) with severe acute-on-chronic slipped capital femoral epiphysis which had been treated by subcapital cuneiform osteotomy. Patients were followed up for a mean of 8 years, 3 months (2 years, 5 months to 16 years, 4 months). Bedrest with 'slings and springs' had been used for a mean of 22 days (19 to 35) in 22 patients, and bedrest alone in two, before definitive surgery. The Iowa hip score, the Harris hip score and Boyer's radiological classification for degenerative disease were used. The mean Iowa hip score at follow-up was 93.7 (69 to 100) and the mean Harris hip score 95.6 (78 to 100). Degenerative joint changes were graded as 0 in 19 hips, grade 1 in four and grade 2 in two. The rate of avascular necrosis was 12% (3 of 25) and the rate of chondrolysis was 16% (4 of 25). We conclude that after a period of bed rest with slings and springs for three weeks to gain stability, subcapital cuneiform osteotomy for severe acute-on-chronic slipped capital femoral epiphysis is a satisfactory method of treatment with an acceptable rate of complication.

    ABSTRACT: Frontal "depowered" air bag systems are underdesign today to be even more effective than current air bags in saving lives, while at the same time reducing the potential of causing an air bag induced serious injury or death. Stereovision real-time occupant sensing systems (airbag suppression) have been developed at Delphi Automotive Systems for use in comercial vehicle applications. One of the issues in such a system is that the irrelevant non-stationary background information within the field of view of the cameras results in less robust occupant classifications. In this paper, a disparity-based image segmentation method is provided. The input images are first segmented according to a pre-determined disparity threshold map and the real-time disparities of the occupants. Binary image processing techniques are used to reject noise introduced into the segmented images through low- resolution disparity calculations. The segmented images are then used for image feature extraction for a neural network classifier. For comparison, two neural network classifiers were created with and without the infrared image segmentation. Our experiements on segemnted images shown an increase of the classifier performance by at least 23% on a large database of IR images collected in extreme outdoor conditions.

    ABSTRACT: Estimating the probability distribution of deformation is essential in the performance-based design. As for composite breakwaters, the most significant performance requirement is usually the stability against sliding. Several criteria, such as the expected sliding distance and the exceedance probability for certain sliding distance during its lifetime, are proposed in order to optimize the design from an economical standpoint. In this paper, the verification procedures of the sliding stability are described and the most rational thresholds of these criteria according to the significance of the structures are proposed. This design method guarantees the structures for same stability irrespective of design conditions, such as extreme wave statistics, water depth, and tidal range. This procedure can be applicable not only to composite breakwaters, but also to other coastal structures.

    ABSTRACT: Slipped capital femoral epiphysis is a condition likely to be encountered by all practising orthopaedic surgeons. A sound knowledge of the risk factors, presentation, investigation and management is essential to prevent the potentially significant consequences of missing the diagnosis. We present an overview of the condition, along with a review of the relevant literature to date.
