Try Nano Fx, the next standard in marrow stimulation.
Arthrosurface has launched a novel device for marrow stimulation named NanoFx (Nanofracture) that provides a better solution than a standard microfracture technique for reaching into the bone to access marrow.
The Arthrosurface NanoFx instruments consist of a reusable Hand Instrument and a single use disposable PleuriStik™. The 1mm PleuriStik™ disrupts less surface area than a standard microfracture technique and it was purposefully designed to reduce damage to the subchondral plate. It penetrates down to a standardized 9mm depth to reach the targeted marrow cells, three times deeper than comparable microfracture techniques. When tested against an awl or k-wire, NanoFx resulted in thin, fragmented cancellous bone channels without rotational heat generation. It also demonstrated deep cancellous bone perforation with a higher number of open trabecular channels.
Microfracture (4A): Trabecular wall thickness and density increased by apparent bone compression; limited trabecular channel access; channel borders with non-anatomic regularity; microfracture channel margins: Dense, compressed bone deposit (right).
Nanofracture (4B): Trabecular wall thickness and density appears normal; large number of open trabecular channels; anatomic irregularity of trabecular channel borders intact; nanofracture channel margins: Course and fragmented trabecular bone deposits (right).
1mm K-Wire (4C): Trabecular wall thickness and density close to normal; limited trabecular channel access; channel borders with non-
anatomic regularity; k-wirechannel margins: Pulverized and dense osseous deposits (right).
