Two major design parameters to total hip arthroplasty which can be selected to optimize for anatomical variation are head diameter and neck length. By using a cadaveric pelvis mounted in a three-dimensional protractor, it was shown that increased head-neck diameter ratio results in increased range of motion, with decreased prosthetic impingement, and that(More)
STUDY OBJECTIVE To determine the effectiveness of a cervical-spine immobilization using a rigid cervical extrication collar and an Ammerman halo orthosis with and without spine boards. DESIGN A mixed model multivariate design with one within factor (device type) and one between factor (spine board application). SETTING Radiology suite. TYPE OF(More)
—This paper presents a reconfigurable many-core platform performing fixed point DSP applications supporting up to 64 cores routed in a hierarchical network. To demonstrate an application, electroencephalogram (EEG) seizure detection and analysis is mapped onto the cores. The individual cores are based on a 5 stage RISC pipeline architecture optimized to(More)
—This paper presents a low power platform which performs continuous multi-channel detection and analysis of seizures for epilepsy patients. The detection unit, upon detecting a seizure, enables an analysis circuit that locally processes and transmits energy and frequency contents of the EEG data. Transmission traffic reduction of 256x is achieved by locally(More)
Thirty-eight (49 per cent) of seventy-seven paraplegic patients whose level of injury was at or caudad to the second thoracic vertebra were found to have signs and symptoms of carpal tunnel syndrome. The prevalence of carpal tunnel syndrome was found to increase with the length of time after the injury. In the eighteen patients in whom manometric studies(More)
Sixty-three palmar-shelf arthroplasties (so-called pseudofusions of the wrist) that had been performed between 1970 and 1978 in forty-nine patients were evaluated. The length of follow-up averaged eighty-three months (minimum, twelve months for the wrists that fused and twenty-four months for those that did not). Preoperatively, all wrists were painful,(More)
An acetabular cup with a 270 degree rim wire has been designed to assist in the radiographic assessment of acetabular cup orientation in total hip arthroplasty. A study was conducted analyzing the component in various positions of lateral opening and version with three different X-ray-beam centering positions. The 270 degree acetabular rim wire allowed for(More)
