Official Title: Above Versus Below-elbow Casting for Conservative Treatment of Distal Radius Fractures: a Randomized Controlled Trial

Brief Summary: For the non-surgical treatment of distal radius fractures in adults a variety cast options are available, including or not the elbow joint. The literature is inconclusive regarding the need to immobilize the elbow joint after reduction of the distal radius fracture.This study was undertaken to evaluate the best method of immobilization between the above and below-elbow cast groups at the end of 6 months of follow-up.

Detailed Summary:

To determine the best method of immobilization ( below elbow versus above elbow splint) in patients with distal radius fractures at the end of 6 months of follow-up:

• Type of study: Prospective, randomized and controlled trial.
• Patient recruitment: Adults attended in emergency room with closed acute displaced distal radius fracture will be reduced under general venous anesthesia with fluoroscopic control.

Displaced and reducible fractures (after venous anesthesia) will be included if one of these conditions is present: Radial height - loss > 2 mm , radial Inclination- loss > 5°, volar tilt - loss > 10°, ulnar variance - loss > 2 mm, intra-articular step off or gap - > 2mm . The contralateral side will be used as a reference.

The eligible participants will be informed about the nature and purpose of the study by reading the "Informed Consent Term" after ageeement, patients will included in the trial and randomized.

• Maintenace of reduction will be defined as the maintenance of the parameters listed above.
• Patients with above elbow immobilization will remain for 4 weeks with splint followed by 2 weeks of below elbow immobilization. The immobilization will be removed with 6 weeks.
• The primary outcome is: maintenance of reduction by evaluation of radiographic parameters (wrist radiographs) at one, two, three, four, six, eight, twelve and twenty four weeks after fracture reduction.
• Secondary outcomes: self-reported function assessment Disabilities of the Arm, Shoulder and Hand questionnaire

  Current Primary Outcome: maintenance of reduction by evaluation of radiographic parameters (wrist radiographs) [ Time Frame: 6 weeks after fracture reduction. ]

  Posteroanterior and lateral x-rays of the wrist to measure radiographic parameters to determine maintenance of reduction will be done every follow up visit. Measurements of the alignment will be made on the radiographs with a marker, straight edge, and protractor. The radiographic measurement technique will be standardized, and repeatability testing demonstrated by a complete blinded assessor. All radiographs will be reviewed by one of the four authors.
  
  
  

  Original Primary Outcome: Same as current
  
  

  Current Secondary Outcome:

  • Disabilities of the Arm, Shoulder and Hand questionnaire (DASH). [ Time Frame: Two, six, eight, twelve and twenty four weeks. ]
    The DASH questionnaire was developed as an instrument for patients with upper-extremity injuries. The survey contains 37 questions related to the function of the hand, wrist, elbow, and shoulder.
  • Patient Rated Wrist Evaluation (PRWE) [ Time Frame: Eight, twelve and twenty four weeks. ]
    The PRWE contains 15 items that are specific to determine the degree of musculoskeletal disability related to the wrist. Both are validated tools of upper extremity function.
  • Pain (VAS - "Visual Analogue Pain Scale"). [ Time Frame: one, two, three, four, six, eight, twelve and twenty four weeks after fracture reduction ]
    Visual Analogue Pain Scale(VAS). It is a unidimensional measure of pain intensity, which has been widely used in diverse adult populations. Pain in VAS is a continuous scale comprised of a horizontal line with 10 centimeters (100 mm) in length, anchored by 2 verbal descriptors, one for each symptom extreme by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 100 [100-mm scale]). The participants are asked to report pain intensity in the last 24 hours. The respondent is asked to place a line perpendicular to the VAS line at the point that represents their pain intensity. Using a ruler, the score is determined by measuring the distance (mm) on the 100mm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100.
  • Objective functional evaluation (goniometry and dynamometry) [ Time Frame: Six, eight, twelve and twenty four weeks follow up visit. ]
    The objective functional evaluation measurement will be made with protactor to measure wrist flexion, extension, ulnar deviation, radial deviation and pronosupination
