CMF - Studies

SPINALOGIC™

CMF treatment associated with

97%

lumbar fusion compared to 62% patients that received no stim.⁴

Peer reviewed results show

that smokers treated with CMF were reported to have higher fusion Rates than smokers that did not receive stimulation.

Effectiveness of combined magnetic field bone growth stimulation on lumbar spinal fusion outcomes: a single center retrospective analysis comparing combined magnetic field to no stimulation.*

FUSION RATES	TREATED WITH CMF™	TREATED WITH NO STIM
Overall	97% (n=343)	62% (n=309)¹
Smokers	94%	61%²
