Infinity OCT Flashcards
What encompasses RodSync Technology?
7 main points

8.7mm of medial/lateral offset without the use of lateral connectors
Friction fit saddles help MAS head maintain position when capturing rod in head of screw.
24% more full threads for increased engagement in bone and stronger tactile feel
Tapered, self tapping tip design to facilitate location of pilot hole.
Extended size range offering

- 5 - 8-42 (2mm increments)
- 5 - 15-40 (5mm increments) “transition screw”
One screw head fits all rod diameter and materials for procedural and logistical efficiency
What is distance of shank length on non-threaded portion of PT screws?
What sizes do we offer?
Uniform 10mm unthreaded portion on all size screws.
3.5 & 4.0 diameters
Length 18-40mm (2mm increments)
What are X-Small Cervical Screws
Diameter = 3.0 Length = 8mm-34mm
These 3.0 MAS require use of MAS crosslink at each level in which the 3.0 MAD is intended to be used
What are Transition Screws?
Diameter = 5.5 Length = 15mm - 40mm (increments of 5mm)
What improvements did we make to the infinity set screws?
Designed to minimize cross threading.
- QuickStart lead in thread that reduces the chance of the screw starting off axis
- 114% thicket thread crest
Increased driver/screw interface with 20% deeper hex engagement
What straight rod options do we offer
- 2 Titanium
- 5 Titanium
- 5 Chromaloy Plus
What diameter rods come in Pre-cut / Pre-Bent, Occipital Adjustable Rods and Occipital Pre-Curved Rods.
- 5 Titanium
3. 5 Chromaloy Plus
What type rods do we offer in Cervical Thoracic Tapered Rods?
- 5-4.75 Titanium & Chromaloy Plus
- 5-5.5 Titanium & Chromaloy Plus
- 5-6.0 Titanium & Chromaloy Plus
What is rod stiffness and how does it effect clinical results?
The resistance to deformation(bend) when a force is applied
Stiffness maintains stability. Higher the stiffness of a rod, requires more force to bend. Consider a rod with high stiffness to maintain correction under high construct demands
What is Yield Strength?
The amount of force necessary to cause a PERMANENT bend in the rod.
A rod with lower yield strength requires less force to permanently bend and holds it shape (less spring back)
What is notch sensitivity?
The tendency of notches to form in the rod.
Notches are indentations on the rod caused by bending and can reduce fatigue strength of a rod and ultimately lead to rod breakage or construct failure.
Materials that are less notch sensitive can withstand higher compression fatigue loads
What are main features of Occipital Adjustable plates?
3 home midline fixation to the Occiput to maximize bone purchase in the midline
Rotating and translating saddles to facilitate rod placement
Arched shape of the plate for bone grafting on occiput
Pre-contoured with a radius of curvature for an Anatomic fit to the occiput
Two sizes to accommodate varying patient anatomies
What are key highlights of Occipital screw connectors
Low profile Occipital fixation option
Allows for six points of Occipital midline fixation
Flexibility in placement on the occiput in cephalad/caudal directions.
Two length of screw connectors available for flexibility in the Medial/Lateral plane
Dorsal height adjustments capabilities accommodate uneven bone surfaces.
What Occipital Bone Screws do we offer?
Standard (flat) and tapered (slight point) tip designs
- 5 - 6-14
- 0 - 6-14
Increased thread volume in standard tip design
Deeper hex depth for increased driver engagement
What are the key highlights regarding Occipital Adjustable Rods?
- Reduced profile of hinge portion for ease of fit at the OC Junction
- Requires less rod bending to fit difficult anatomy as compared to a straight rod
- Angulation can be adjusted in the wound to achieve desired alignment goals
- Provisionally Adjustable without disassembly
- Titanium and Chromaloy Plus
What are key highlights for Occipital pre-curved Rods?
- Pre-contoured to match the anatomy of the OC Junction.
- Lower profile option for difficult anatomy
- Titanium and chromaloy plus
What connectors/domino options do we offer?
Offset Dominos and Open to Open Offset Dominos
- allows for medial/Lateral offset of rods at the transition point
- Open feature on both sides of O/O domino facilitates connection to existing rod without revising construct connections
Axial Domino
- Allows for axial alignment of rod at the transition point
- Connects 3.2-3.5 / 4.5-4.75 / 5.5-6.0
- stepped design feature to accommodate dorsal height differences between rods
MAS Extension Connectors
- connects to MAS to allow for extension of adjacent constructs without revising the existing construct
- ZERO run on the rod
- Enables “dual rod” constructs at levels in which more construct rigidity is desired
- Connects 3.2-3.5 / 4.5-4.75 / 5.5-6.0/6.35
- Simplified assembly steps
- The MAS Extension connectors are intended to be used with 3.5 and larger diameter MAS. Do not use with 3.0 MAS
What Crosslink and lateral connectors are available?
Small =23.5-30.3 This size is included in outlier implant module
Medium =29.5-40.5 Size that comes standard in C3-7 Implant module
Large =39.5-56.5 This size is included in outlier implant module
Footprint of connector =7mm
Rod to Rod Crosslink
- lower profile at the apex of the Crosslink arch
- internal Center set screw and ability to use the MAS Counter Torque improves Screwdriver interface during final tightening of the central lock
- Has a rotating rod connection component to allow for attachment at different levels of the construct
- Adjustable design and various sizes accommodate varying distances between rods
Crosslink, MAS to MAS Attachment
- connects to the top of a MAS head in cases where adjacent screw heads are close proximity to one another
- Integrated connector set screw reduces implantation steps
- Lower profile at the apex of Crosslink arch
- internal Center set screw and ability to use MAS Counter Torque improves Screwdriver interface during final tightening of the central lock
