Ultrasound Assisted Distal Radius Fracture Reduction

• Efficacy of Point of care ultrasound in Identifying colles fracture reduction [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  Physicians performing Bedside ultrasound of colles fractures will be asked to complete likert scales on the adequacy of fracture reduction with ultrasound
  
  

• Number of reduction attempts affected by ultrasound [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  The physician is asked to record the number of fracture reduction attempts as guided by the ultrasound image before and after the post reduction X-ray
  
  
• Time to imaging [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  The physician performing the bedside ultrasound will record the time on completion of the bedside ultrasound and the time of completion of the post reduction X-ray
  
  

The reduction of fractures is a commonly performed procedure in emergency departments (EDs). In most Canadian EDs, reductions are performed by emergency physicians (EPs). The distal radius fracture is the most common fracture requiring reduction. Fracture reduction is time-consuming with several steps required: initial evaluation including x-ray, equipment and personnel gathering, sedation and/or local anesthesia, reduction attempt(s) and splinting/casting, and post-reduction x-rays, with subsequent patient reassessment. These steps have a negative effect on ED patient throughput. Subsequent to the reduction attempt(s), the patient is sent for x-ray often with uncertainty regarding the reduction success. Fluoroscopy is generally not an option for the EP in evaluating accuracy of reduction. If the reduction is not adequate, further reduction attempts are needed. This utilizes more resources, either in the ED or orthopedic clinic or operating room, depending on where further reduction attempts are made.

Emergency ultrasound (EU) in Canada has become a well-established part of emergency medical practice in recent years as evidenced by the latest position statement of the Canadian Association of Emergency Physicians (http://caep.ca/template.asp?id=B5283F4158FB471AA56E480D6277C1AC) and the development of the Canadian Emergency Ultrasound Society (www.ceus.ca). A growing body of literature has shown the utility of EU in the diagnosis and reduction of fractures (1-6). A recent case report (7) showed that EU can be used to aid Colles fracture reduction. Similar to fluoroscopy, EU may be a fast and accurate method of determining successful fracture reduction. Unlike fluoroscopy, EU is available immediately in the ED. EU may also obviate the need for the post-reduction x-ray, particularly in the setting where the patient will have yet another x-ray at the time of orthopedic follow-up to evaluate for interval loss of reduction. Thus, EU has the potential to significantly reduce time to discharge.

Our study has the following objectives:

• To assess EU utility for guiding reduction attempts of distal radius fractures.
• To compare EU to x-ray for the final assessment of reduction adequacy.
