Above-versus Below-elbow Casting for Conservative Treatment of Distal Radius Fractures

December 9, 2019 updated by: Hospital Dr. Fernando Mauro Pires da Rocha

Above-versus Below-elbow Casting for Conservative Treatment of Distal Radius Fractures: a Randomized Controlled Trial and Study Protocol.

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 Description

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 > 4°, dorsal tilt - > 10°, ulnar variance - loss > 3 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 and self-reported function assessment Disabilities of the Arm, Shoulder and Hand questionnaire(DASH).
  • Secondary outcomes:Patient Rated Wrist Evaluation- PRWE. Pain (VAS - "Visual Analogue Pain Scale"). Objective functional evaluation (goniometry and dynamometry) and rate of complications and failures.
  • Sample Size calculation was calculated based on data derived from one recent randomized clinical trial on the subject. We considered as relevant differences on DASH scores (clinically relevant) when scores are greater than 10 points and standard deviation 15 points. To detect this difference (Student T-test) and statistical power of 95% resulted in a 58 patient sample size per group. We considered an extra 10% for balancing follow up losses. Thus, our inclusion target will be 64 patients per group. We considered the test as bicaudal.

Benefits: Below elbow splinting is easier to apply, lower cost, more comfortable and permits better function for daily life activity.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
maintenance of reduction by evaluation of radiographic parameters (wrist radiographs).
Time Frame: One, two, three, four, six, eight, twelve and twenty four weeks after fracture reduction(radiographs).
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.
One, two, three, four, six, eight, twelve and twenty four weeks after fracture reduction(radiographs).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
DASH questionnaire
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.
Two, six , eight, twelve and twenty four weeks
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.
Eight, twelve and twenty four weeks.
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.
one, two, three, four, six, eight, twelve and twenty four weeks after fracture reduction
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
Six, eight, twelve and twenty four weeks follow up visit.
