Brief Summary:
This is a prospective observational single cohort trial quantifying time to radiographic union (primary endpoint) and convenience, satisfaction, pain and resource requirements (secondary) for patients with non-operatively treated distal radius fractures managed with a thermoformable Exos short-arm brace.

Condition or disease Intervention/treatment Phase
Distal Radius Fracture Other: molded brace Not Applicable

Detailed Description:
The trial will be a prospective trial of a convenience sample of skeletally mature patients with radiographically-confirmed distal radius fractures that can be managed without ORIF. The study population will be defined as all adult patients (>18 years) with stable, non-displaced distal radius fractures. All patients will be independent in activities of daily living. Patients will be screened as candidates for enrollment into the study and if the patient satisfies the inclusion/exclusion criteria, a clinical research coordinator or the study PI/coPI will explain all essential elements of the clinical trial. If the patient agrees to participate, the study coordinator or PI/coPI will obtain informed consent. The patient will still be followed clinically per the PI/coPI's standard of care.

Intervention Details:
  • Other: molded brace
    The moldable brace utilized in the current study will be pre-fabricated and of the short-arm brace variety , which is primarily indicated for non-displaced fractures of the distal radius or distal ulna. The braces are available in multiple sizes for both right and left hands.

Primary Outcome Measures :
  1. bony union [ Time Frame: 2-12 weeks ]
    radiographic time to union

Secondary Outcome Measures :
  1. Patient Reported Outcomes [ Time Frame: 2-12 weeks ]
    Visual Analog Scale from 1(no pain) to 100(extreme pain)

  2. Patient Reported Disability Scale- Quick-DASH [ Time Frame: 2-12 weeks ]
    11 questions rating ability of activites - ranging from no difficulty to unable to do

  3. Patient rated Wrist Evaluation [ Time Frame: 2-12 weeks ]
    Rates pain and function on 1(no pain) to 10 (worst pain)
