TiTaMED Spinal System's Design Concepts

• STANDARD PROFILE CAP

• LOW PROFILE CAP (GRUBSCREW + RING)

Note: The caps are interchangable

Hex socket and ring provides a high degree of protection against stripping and prevents the screw head from splaying open. Surgeon's preference to use either standard or low profile cap.

• TOP LOADING

Allows for easier rod insertion and easier removal when instrumentation is encased in bone.

• BUTTRESS THREAD

Greater contact surface area on thread, therefore reduced tendency to loosen.

• ROUND SCREW HEAD

For removal - screws merely need to be screwed out of their sockets.

• UNIAXIAL ARTICULATING MOBILE/LOCKING HEAD

Locally and Internationally Patented.

This facilitates ease of use. If adjacent screws are not parallel, the rod does not need to be contoured as much as with rigid screws. When used in scoliosis correction, these screws offer translation correction.

• POLYAXIAL ARTICULATING HEAD

When doing multi-level fusions, heads may allow for a less contouring of the rod.

• TITANIUM

All implants are made from the highest grade medical titanium. (ASTM Specifications).

• PARALLEL THREAD

The outside/major diameter is constant, i.e. parallel in all screw types.

Mobile, Locking and Polyaxial Screws, use the same thread profile: the inner core/minor diameter is parallel from the tip to approximately 20mm from the head - thereafter it increases towards the head. This optimizes the strength at the screw-head junction, without compromising grip at the bone-metal interface.

Rigid Screws similarly have the inner core/minor diameter parallel from the tip to approximately 20mm from the head - thereafter it increases towards the head, reaching full outside diameter approximately 3mm from the top of the shank, maximising strength at the screw-head junction.

• TOOLING

Our tooling is userfriendly, reliable, balanced, ergonomically designed. Size is optimized to reduce additional soft tissue damage.

• EASY REMOVAL OF UNIAXIAL AN RIGID SCREWS

An allen key (4.5mm) and a flat screwdriver/paddle/cob is all that is required to remove the uniaxial and rigid screws. For the Polyaxial screws, a special removal tool is required.
