Bone Fracture Healing
Source: Preclinical + Clinical Research
Protocol for supporting bone fracture healing using NIR wavelengths to penetrate to the fracture site. PBM may accelerate callus formation and bone remodeling when used as an adjunct to standard orthopedic treatment.
Protocol Parameters
| Condition | Bone Fracture |
| Wavelengths | 810nm, 830nm, 850nm |
| Dosage | 4-8 J/cm² |
| Irradiance | 50-100 mW/cm² |
| Duration | 5-10 minutes over fracture site |
| Frequency | Daily for first 2 weeks, then 3x/week |
| Body Zone | variable |
| Evidence Level | Emerging |
Mechanism of Action
NIR light stimulates osteoblast proliferation and differentiation, enhances BMP-2 expression, increases local blood flow to the fracture site, and accelerates the transition from soft callus to hard callus. It also reduces fracture-related inflammation and pain.
Key Studies
- Pretel et al. (2007) - PBM effects on bone healing in rats
- Medalha et al. (2012) - PBM for bone repair
Treatment Tips
- *Apply through cast if present (NIR penetrates most cast materials)
- *Coordinate with orthopedic surgeon
- *Do not replace standard fracture management
- *Adequate calcium, vitamin D, and protein support healing
Contraindications
- !Open fractures with active infection
- !Bone malignancy
