Compress Device
Surgical Technique
Device Description
The Compress Device was developed as an alternative
method for fixating a segmental construct to host
bone, while creating a stable bone-prosthesis
interface. Unlike a stemmed construct, the Compress
Device was designed to prevent bone resorption by
allowing stress sharing via the implant and bone while
providing a motion free environment suitable for
biologic fixation (Figure 1).
The system is available in two different anchor
plug/spindle options: the short Compress Device
requiring 45 mm of medullary placement (particularly
advantageous for bone loss) and the standard
Compress Device requiring 80 mm of medullary
placement (Figure 2). The following surgical technique
will focus on the standard 80 mm anchor plug/spindle
offering.
Note:
Please reference the IFU for indications and
contraindications relating to the Compress Device
and OSS implants.
Note:
While the 9 and 13 hole anchor plugs exist,
this technique focuses on 5 hole anchor plugs.
If using the 9 or 13 hole anchor plug, additional
instrumentation may be required.
