Bone fracture healing is prone to failure partly because of its complexity.

Wearing a hip cell phone holder is common.

Holding a cell phone close to a hip bone might make that hip less likely to heal in the event of a fracture.


  • 900 MHz frequencies affect bone fracture healing
  • this is the frequency emitted from many cell phones


  • researchers used fingers to break rat hips
  • they fixed hips with wires
  • they exposed Group 1 to
    • 900 MHz
    • 30 minutes per day
    • 5 days per week
    • 8 weeks

Examination included:

  • radiological (X-ray examination)
  • manual mechanical (biomechanical orthopedic healing examination)
  • histological (tissue structures studied under the microscope)



Researchers used their fingures to fracture rate hips. (Author’s note: I don’t know how they sleep at night.)

Hip fractures exposed to 900 MHz frequencies healed poorly.

Unexposed hips healed normally.

On a scale of one to 9, with high scores being better, these were the  results:

  • histopathological (bone tissue)
    • non-radiated: 8.8
    • radiated: 8.1
  • radiological (X-ray) results:
    • non-radiated: 7.9
    • radiated: 6.6
  • biomechanical  (orthopedic):
    • non-radiated: 1.75
    • radiated:1.2


  • 900 MHz exposure deters hip fracture ability to heal
  • non-ionizing radiation close to the body reduces body’s ability to heal bone fractures


EMFs are well-accepted in treating bone fractures.

The fact that EMFs at 900 MHz prevent bone healing show just how important the photobiomodulation (PBM) optimum treatment window is to a healthy outcome.

Too little, too much, and the wrong frequencies are unhealthy.

  • mobile phone hip holsters expose wearers to cell phone non-ionizing radiation
  • if rat-to-human extrapolation holds up,
    • the holster wearers are damaging their hip bones
    • the damage from 900 MHz cell phone exposure will make hip fractures less likely to fully heal
