3.1 Hardware
The MAXFRAME AUTOSTRUT System consists of both
hardware components (struts and control system with
attached lightweight motors) and software. The hardware
components are attached to a circular external ring fixa-
tion frame, the MAXFRAME System. The hardware is
validated for use with the MAXFRAME AUTOSTRUT
Software.
MAXFRAME AUTOSTRUT System components are com-
patible with the DePuy Synthes MAXFRAME Multi-Axial
Correction System ("MAXFRAME"). The MAXFRAME
System hardware is coupled with the MAXFRAME Soft-
ware for use in the creation of patient treatment plans,
which detail required strut adjustments. Supplementary
to the use of MAXFRAME Software, is the MAXFRAME
AUTOSTRUT Software controlling and recording the
struts adjustments.
The MAXFRAME AUTOSTRUT system includes the
following hardware components:
3.1.1 Struts
MAXFRAME AUTOSTRUT hexapod struts are designed
to shorten and lengthen according to the treatment regi-
men prescribed by the physician.
MAXFRAME AUTOSTRUT struts are compatible with
MAXFRAME hardware (ring sizes 90–270 mm). Three
sizes of MAXFRAME AUTOSTRUT hexapod struts are
available – short, medium and long. The lower section
design is identical across all sizes. The only difference
between the struts is the length of the upper section
and the range of travel. X-Short and XX-Short strut sizes
are not available. Treatment plans requiring X-Short or
XX-Short struts cannot be accommodated and will be
rejected by the AUTOSTRUT Software.
