Low Dose CT Distal Radius Fractures

2018-02-11 17:22:11 | BioPortfolio


This study is a prospective, departmental funded study examining the outcomes of Low Dose CT scans compared to Conventional Dose CT scans in patients who present to Duke University with a Distal Radius Fracture.


The purpose of this study is to compare the use of a conventional dose computed tomography scan (C-CT) to a low dose computed tomography scan (L-CT) in the assessment of articular displacement, and development of a treatment plan for intraarticular distal radius fractures in an effort to reduce the radiation exposure to future patients with this injury pattern. Reviewers will be tasked with reporting data aimed at investigating 3 primary outcome measures: 1) Are L-CT images of sufficient quality to be used for diagnostic purposes, 2) Can accurate measurements of step and gap displacement be made on L-CT images, 3) Do proposed treatment plans change with the use of L-CT relative to those chosen based on C-CT images We hypothesize that reviewers will find L-CT images of sufficient image quality for diagnostic purposes, measurements of step and gap displacement will not be significantly different between L-CT and C-CT, and no significant differences in treatment options will be chosen based on the use of L-CT rather than C-CT for the same fracture. The secondary aim will be to evaluate the interobserver and intraobserver reliability of L-CT in evaluating intraarticular fractures of the distal radius.

A Study Examining The Effect Of Wrist Joint Haematoma Washout As An Adjunct Procedure To Plating Of The Distal Radius In Fractures Of The Distal Radius Involving The Wrist Joint

Intra-articular fractures of the distal radius are common in urban populations and result in significant morbidity in terms of time away from work. Volar plating of the distal radius is a ...

Operative Treatment of Intra-Articular Distal Radius Fractures With Versus Without Wrist Arthroscopy

Open reduction and internal fixation of intra-articular distal radius fractures leads to better functional outcomes the first 6 months compared to non-operative treatment. However, some pa...

Exploration of Wrist Soft Tissue Injuries Associated With Wrist Fractures

The purpose of this study is to describe and stage lesions of the triangular fibrocartilage complex (TFCC) in association with distal radius fractures. 20 patients with dorsally dislocated...

Outcome Study of Complex Distal Radius Fractures

The purpose of this study is to collect information about how people do after different treatments of a broken wrist to see if one treatment has better results.

Metaphyseal Distal Radius Fractures

The number of osteoporotic fractures, among which the fractures of the lower extremity of the radius (16 % of fractures seen in emergencies) is going to increase. Several surgical techniqu...

The objective of this study was to determine the percentage of radiographs which showed a fracture of the wrist. Secondary, the fracture characteristics and the received treatment were determined. Add...

Proximal radius fractures in children: evaluation of associated elbow fractures.

Additional fractures occur in association with proximal radius fractures, but the extent of these secondary injuries has not been systematically assessed.

Timing of Treatment of Open Fractures of the Distal Radius in Patients Younger Than 65 Years.

The authors aimed to characterize surgical and functional outcomes of open fractures of the distal radius in patients younger than 65 years. At their level I trauma center, the authors conducted a ret...

Factors associated with the decision for operative versus conservative treatment of displaced distal radius fractures in the elderly.

The treatment of senile distal radius fractures had not been clearly defined. The objective of this study was to identify the factors associated with the decision for operative treatment of displaced ...

Stable rates of operative treatment of distal radius fractures in Ontario, Canada: a population-based retrospective cohort study (2004–2013)

Rates of surgical management of distal radius fractures are increasing internationally despite the higher cost and limited outcome evidence to support this shift. This study examines the epidemiology ...

Medical and Biotech [MESH] Definitions

Fractures of the RADIUS.

Fractures of the short, constricted portion of the thigh bone between the femur head and the trochanters. It excludes intertrochanteric fractures which are HIP FRACTURES.

The direct continuation of the brachial trunk, originating at the bifurcation of the brachial artery opposite the neck of the radius. Its branches may be divided into three groups corresponding to the three regions in which the vessel is situated, the forearm, wrist, and hand.

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.

The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.
