Foot and Ankle

  JOINT PREPARATION (Metatarsal) A skin incision is made over the dorsum of the lesser metatarsal phalangeal joint. The distal portion of the metatarsal head is resected at the appropriate level for the existing deformity or disease. Using the supplied Reamer, prepare the medullary canal of the metatarsal. The three laser mark lines refer to the three proximal Implant stem lengths. Refer to Sizing Chart for proximal stem lengths. JOINT PREPARATION (Phalanx) The base of the proximal phalanx is preserved if possible. Using the supplied Reamer, the medullary canal of the proximal phalanx is prepared. Refer to Sizing Chart dimension for distal stem lengths. IMPLANT SIZING Place the Implant Trials into the prepared joint in order to select the correct size of Implant. With the Trial in place, load the foot to check that there is no jamming of the Implant. The Trial is then removed and the joint is thoroughly irrigated. The color of the chosen Trial corresponds to the color code on the associated Implant package. IMPLANT PLACEMENT The appropriate Implant is then inserted. Important – HANDS ONLY INSERTION: Do not use forceps or other instruments to grab, grasp and/or insert the Implant. This can damage the Silicone Implant. Excessive handling of the Implant should be avoided. After Implant placement, flush the joint with copious irrigation. CLOSURERepair and suture the joint capsule, being certain to completely cover the Implant. (Optional technique procedure: Tack down the extensor digitorum longus tendon proximal to the MTP joint, using one or two absorbable sutures, with the digit just slightly plantar flexed at the MTP joint. This will prevent retrograde buckling (dorsal contracture) of the joint while the foot is elevated post operatively, thus allowing the joint capsule to heal in its normal position. The sutures will dissolve after a few weeks, and the tendon and joint will resume function.) Wound closure is performed with sutures of the surgeon’s choice.

These compact, self-drilling and self-tapping screws can be easily implanted in any kind of cortex, using the supplied ergonomic and easy-to-use instrumentation. Features:  Titanium Alloy cannulated screws Three diameters available – 2.25mm, 2.60 mm and 3.00mm Self-Drilling, Self-Tapping Screws – simple and time effective Low profile head design easily countersink (countersink provided only for hard bone) Allows for minimally invasive surgery using percutaneus instrumentation K-Wires 0.8mm and 1.0mm reduces the chance of K-wires deviating/snapping upon insertion Easy to use and colour coded instrumentation Available non-sterile (on tray) and pre-sterile

Features: Made of PEEK (Polyetheretherketone) A non-resorbable polymer that has been shown to be highly biocompatible with a long track record in orthopaedics Stability by Design Opposing threads (screw and barbed segments) allow the ability to generate extra compression across the joint Cannulated Provides an option to temporarily pin the corrected phalanx across the MPJ with a guidewire Available in 3 sizes to accommodate size variations of the lesser toes

The following equipment can be hired: Low-speed, high-torque burr machine Range of burrs (shannon, wedge, conical) MIS specialist rasps and other equipment Range of self drilling/ self tapping cannulated screws 2.6mm, 3.0mm, 4.0mm, 6.0mm and 8.0mm Whether you are planning to do a Calcaneal Osteotomy or a Minimally Invasive Chevron Akin surgery Lavender Medical is able to offer a competitive option for all your Minimally Invasive needs. We are also able to offer courses and live surgery should you wish to learn more about MIS in the foot. Indications and what is needed: MIS Akin – MIS equipment with 2.6mm or 3.0mm cannulated screws MIS Cheilectomy – MIS equipment only MIS Chevron & Akin – MIS equipment with 2.6/ 3.0 and/or 4.0mm cannulated screws MIS DMMO – MIS Equipment only MIS Calcaneal – MIS Equipment with 6.0mm or 8.0mm cannulated screws

The bevelled proximal area of the screw enables it to be positioned flush with the medical cortex of the first metatarsal, this minimalizes any potential screw prominence or soft tissue irritation. The increased head length provides a greater thread contact upon angled insertion with the medial cortex which creates interfragmentary compression and increased stability. Key Features: Self-drilling Self-tapping
