STEP 1:
BATTERY CHARGING
The EBI Bone Healing System
®
Stimulator runs on nickel metal hydride batteries.
Before
treating with the system,
the patient will need to charge the batteries to a full charge. At room
temperatures (24˚C [75˚F]), charging may take up to two hours. In warm temperatures (29˚C
[85˚F]), the unit may take up to five hours to charge.
Plug the battery AC charger/power unit
into a grounded wall outlet.
Attach battery AC charger/power unit to
the battery charger cradle.

FRACTURE HEALING IN RESPONSE TO PEMFs
(cont’d)
• The second stage of healing is indicated by the appearance of consolidated
bone stress lines that bridge the fracture gap. This bridging may appear initially,
but should progress until cortical continuity occurs in all cortices as visualized on
AP and lateral x-rays. Once cortical continuity is established and clinical union
occurs (i.e. no motion), the PEMFs treatment may be discontinued. These effects
are normally observed approximately three to eight months after treatment is
initiated. At this point, the patient should be put on a program of guarded
rehabilitation to prevent refracture.
• Subsequent remedullarization and remodeling occurs according to Wolff’s Law
and may take from twelve to twenty-four months to complete.
OPERATING INSTRUCTIONS
Before using the EBI Bone Healing System

Stimulator for the first time, the control unit
should be charged.
