PURPOSE To establish the accuracy, precision, and clinical feasibility of a novel technique of computer-assisted distal radius osteotomy for the correction of symptomatic distal radius malunion. METHODS Six patients underwent a computer-assisted distal radius osteotomy and were followed-up for an average of 25 months. Objective radiographic measurements(More)
OBJECTIVE The objective was to develop a fixation-based three-dimensional presurgical planner and an intraoperative guidance system for distal radius osteotomy. Fixation-based surgery is a technique premised on using a fixation device, such as a fracture-fixation plate, during the alignment and distraction phases of an osteotomy. MATERIALS AND METHODS The(More)
A three-dimensional developmental finite element model has been created to analyze load transmission pathways in the constrained carpus during static compressive loading. The bone geometry was extracted from an in vivo computed tomography scan using a combination of commercial and proprietary software. The complete geometry, including bone, cartilage, and(More)
Automated noninvasive blood pressure (NIBP) monitors, or automated sphygmomanometers, have been increasingly used both inside and outside clinical environments. An extensive survey of such monitors was carried out over the past five years. This survey covers a broad spectrum of monitors including ambulatory monitors, bedside and transport monitors,(More)
Oscillometric blood pressures are derived from the amplitude envelope of oscillometric pulses generated in an occlusive cuff during cuff inflation or deflation; one factor which will affect the characteristics of these pulses is the size of the cuff bladder. Because limiting values are stipulated in recommendations and standards for bladder sizes, there is(More)
We investigated the dependence of 20 radiographic carpal measurements (carpal indices) on rotational positioning errors in posteroanterior and lateral radiographs. The measurements were made from "true perspective" digitally reconstructed radiographs created from computed tomography data. Most posteroanterior indices were not affected by rotation. Carpal(More)
The purpose of this study was to measure the structural stiffness (load/displacement response) and elastic modulus (stress-strain response) of the glenoid labrum at different locations throughout the tissue. It was intended that the results of this work would serve to define the properties of the labrum. This in turn may permit a better understanding of(More)
Automated noninvasive blood pressure (NIBP) monitors have found widespread use both inside and outside clinical environments in recent years. Present methods for evaluating the measurement accuracy of this class of devices involve population studies that are meticulous, time-consuming and costly. These methods are also impractical for routine evaluation.(More)
The development of methods and simulators for evaluating noninvasive blood pressure (NIBP) monitors has been dynamic during the past few years. As a complement to a previous review paper in this journal, several additional developments are reported in this paper. These include evaluation methods developed in Australia, the United States and Europe, as well(More)
Characterization of the motion of the hand and wrist requires reference to the underlying bones which, for three-dimensional analyses, are assumed to be rigid bodies. Stereoradiogrammetric techniques involving the identification of prominent bone landmarks have been used as the standard against which surface markers used for in vivo testing have been(More)
