Distal Radius Fracture
Conditions
Brief summary
Distal radial fractures (DRF) are the most common fractures encountered in health care. Annualized estimates in the United States alone suggest an incidence of approximately 640,000 cases, and rising, per year. Most fractures may be treated in a plaster cast, but unstable fractures tend to displace without a surgical procedure. 1 Pulsed electromagnetic field (PEMF) is one modality commonly used to stimulate bone generation throughout various clinical settings including orthoapedic surgery. PEMF has been shown to primarily effect vascular generation, formation and neovascularization2,3. This may help decrease time to healing and allow patients to return to normal activities sooner. Additional study demonstrated that PEMF exposure increased cell proliferation, adhesion and the osteogenic commitment of MSCs, even in inflammatory conditions. In this in-vitro model PEMFs increased the expression of anti-inflammatory cytokines, such as IL-10, and reduced the expression of the pro-inflammatory cytokine IL-1 4. The distal radius fracture was chosen as the model to test the effects of PEMF treatment because it includes both trabecular and cortical bone, is accessible for radiographs, has little soft tissue that can distort the radiograph, and is amenable to multiple functional endpoints. The purpose of the study is to determine whether the use of FHP by means of pulsed electromagnetic fields in acute distal radius fractures will accelerate healing both clinically and radiotralogically
Interventions
DEVICEFracture Healing Patch (FHP)
The Fracture Healing Patch (FHP) is an external silicone patch that contains inside micro-electronic modulus, which generates a pulsed electromagnetic field (PEMF) to enhance and improve fracture healing. The FHP is placed under the cast at the fracture site. Throughout the treatment period the FHP produces a pulsed electromagnetic field. The FHP houses a battery, a microelectronic module and a coil that produce the PEMF.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in radiographic fracture healing | Radiographic images (X-ray) will be performed for each subject from day 0 and onward: week 2,4, 6 and 12. | Change from baseline in radiographic fracture healing will be measured. Radiographic healing will be defined as the interval in days between the occurrence of the fracture and the time when bridging in three of four cortices is seen on X-ray images. A measurement will be made at each follow up evaluation by using Radius Union Scoring System (RUSS) score |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in improvement of function | Functional assessment will be performed at 4, 6 and 12 weeks from treatment | For assessment of functional deficit, disability and pain level, the Patient Rated Wrist Evaluation (PRWE) will be used. The PRWE is an easy 15-item questionnaire designed to measure wrist pain and disability in activities of daily living. The PRWE allows patients to rate their levels of wrist pain and disability. Pain Score = Sum of the 5 pain items (out of 50) Best Score = 0, Worst Score = 50 Function Score = Sum of the 10 function items, Divided by 2 (out of 50) Best Score = 0, Worst Score = 50 Computing the Total Score Total Score = Sum of pain + function scores Best Score = 0, Worst Score = 100 |
