Methods of genomic competency integration in practice.

Purpose: Genomics is increasingly relevant to health care, necessitating support for nurses to incorporate genomic competencies into practice. The primary aim of this project was to develop, implement, and evaluate a year-long genomic education intervention that trained, supported, and supervised institutional administrator and educator champion dyads to increase nursing capacity to integrate genomics through assessments of program satisfaction and institutional achieved outcomes.

Design: Longitudinal study of 23 Magnet Recognition Program® Hospitals (21 intervention, 2 controls) participating in a 1-year new competency integration effort aimed at increasing genomic nursing competency and overcoming barriers to genomics integration in practice.

Core decompression of the distal radius for the treatment of Kienböck's disease: a biomechanical study.

Purpose: The purpose of this study was to evaluate the biomechanical effect of core decompression of the distal radius for the treatment of Kienböck's disease.

Methods: In 7 fresh cadaver upper extremities, axial loads were applied and the pressure in the radiocarpal joint measured using pressure-sensitive film before and after core decompression of the distal radius.

Results: Biomechanically, the stiffness of the distal forearm statistically decreased significantly from 229.

Three-dimensional modeling and animation of two carpal bones: a technique.

The objectives of this study were to (a). create 3D reconstructions of two carpal bones from single CT data sets and animate these bones with experimental in vitro motion data collected during dynamic loading of the wrist joint, (b). develop a technique to calculate the minimum interbone distance between the two carpal bones, and (c).

Biomechanical study of pins in cementing of contained proximal tibia defect.

Defects from curettage for giant cell tumors of bone frequently have been reconstructed with bone cement with or without reinforcement pins. The biomechanical basis for the addition of reinforcement pins was examined using a model of a contained defect in the proximal tibia. Fifty-four cadaveric proximal tibia in matched pairs were divided into five test groups: intact tibia, medial metaphyseal contained defect, defect reconstructed with cement alone, defect reconstructed with cement and pins inserted within the medullary canal, and defect reconstructed with cement and pins inserted through the cortex.

Biomechanical analysis of humeral diaphyseal segmental defect fixation.

With disseminated malignancies, segmental defects of the humeral diaphysis may occur from surgical resection or as a complication of failed prior internal fixation. This study directly compared the biomechanical properties of a second generation titanium modular intercalary humeral spacer (segmental defect replacement prosthesis) with those of a modern locked humeral nail combined with methylmethacrylate (intramedullary nail) or with an intercalary allograft spacer (allograft nail composite) for fixation of segmental defects of the humeral diaphysis. Eighteen matched pairs (36 specimens) of fresh-frozen humeri were prepared in a standard fashion to create a 5-cm middiaphyseal defect and were divided randomly into three groups of 12 specimens each, using three different reconstructive methods.

The effect of sectioning the dorsal radiocarpal ligament and insertion of a pressure sensor into the radiocarpal joint on scaphoid and lunate kinematics.

The role of the dorsal radiocarpal wrist ligament has been the subject of several investigations. Several biomechanical studies have used sensors inserted dorsally into the wrist joint to evaluate its pressure distribution. The purpose of this study was to evaluate whether a dorsal capsulotomy that sections the dorsal radiocarpal ligament or insertion of a flexible pressure sensor alters scaphoid or lunate kinematics.

Radiologic evaluation of the ulnar styloid.

The ulnar styloid (US) architecture was examined radiologically and directly by dissection in 13 cadaver wrists to examine a potential relationship between US shape and US abutment syndrome and to determine an optimal radiographic view that could be used to detect US fractures. A higher incidence of US abutment syndrome in the radially deviated US type was observed by dissection. Radiographs taken at varying shoulder abduction angles suggested that the base of the US and ulnar head are not round.
