TYLOS ANKLE ARTHRODESIS NAIL

TYLOS The TYLOS™ ankle arthrodesis nail from the Be POD™ range has a unique posterior locking system, thanks to implantation of a trans-calcaneal screw of the threaded wedge type. This guarantees considerable stability and thus reduces the risk of disassembly of the system or migration of the screw. Side locking with a cortical screw • Cannulated nail, available in : • • Posterior locking with a wedgetype trans-calcaneal screw - 3 lengths : 160, 200, 250 mm - 3 diameters : 10, 11, 12 mm Material : Stainless steel Multi-axial stabilisation - 1 single wedge-type trans-calcaneal screw...

TALOCRURAL APPROACH In certain exceptional cases, and providing that the surgeon is used to it, this approach may be done through an arthroscopic procedure. In most cases, the recommended procedure a standard anterior approach made between the tendons of the anterior tibial and the common extensor tendons after sectioning the retinaculum of the extensors, whilst respecting the foot’s dorsal pedicle (Fig. 2). After arthrotomy, the joint is approached for freshening of the articular surfaces, respecting as much as possible their geometry and insisting on the malleolar sulci using a drill and...

It is mounted on the motor and introduced in an ascending, transosseous manner, controlling its insertion on the image intensifier (Fig. 5). It must be positionned exactly in the centre of the tibial pilon, both face on and in profile, with the hindfoot in its axis. The choice of introduction point for the nail must be made very carefully as the nail cannot and must not reduce the hindfoot automatically. The cortical bones are hollowed out (Fig.6) using a cannulated drill bit (ref. 253264) before inserting the hand reamers (ref. 253248, 253249 and 253250). 5 - Implantation of the threaded...

TYLOS™ trans-calcaneal screw POSTERIOR LOCKING The soft tissue retractor (ref. 253252) is assembled in the guide for trans-calcaneal screws (ref. 253261), and screwed into the centering guide sleeve (ref. 253256). A small posterior skin incision is made to introduce the entire assembly into contact with the bone (Fig. 10). After withdrawing the soft tissue retractor and distal screw guide, packing with drill bit M6 (ref. 253259) is performed until the nail is blocked. Measured length A (which corresponds to the measurement of the posterior part of the screw) will be retained by direct...

LATERAL LOCKING The posterior guide is removed to introduce the lateral guide on to the 2nd branch of the fixation nail holder, held in place by screw M5 (ref. 253681). 160 mm 14 - Assembling the TYLOS™ implantation guide - Lateral drill guide A maximum of three proximal, and two distal, screws can be used. Markings indicate the holes to be used depending on the length of the nail (160 or 200 mm classically; a specific lateral guide is delivered with the optional 250 mm nail) (Fig. 14). The procedure for percutaneous implantation is the same for each: assemble the soft tissue retractor...

EXTRACTION OF THE MATERIAL The lateral screws are simply unscrewed once the approach has been returned to (ref. 257381). The polyethylene plug protecting the head of the calcaneal screw is cleared, making it possible to screw its extractor into place (ref. 254597). The extractor is screwed in backwards, making it initially possible to connect it to the screw and then, when it reaches its blocking point, to unscrew it in a second stage (Fig. 20). For the nail, once you have returned to the plantar approach, screw in the M6 connection screw (ref. 253251) on to which the nail extractor (ref....
