Variable Angle LCP Forefoot/Midfoot System 2.4/2.7. Procedure specific plates for osteotomies, arthrodeses and Compression feature Compression holes used with compres- sion wires and forceps allow for tactile Variable angle Screw holes allow up to 1 5° off-axis screw angulation in all directions. Minimized soft tissue irritation Low profile plates with rounded edges and highly polished surface minimize soft tissue irritation. The system consists of general and pro- cedure-specific plates, variable angle locking and cortex screws, and a com- pression feature, to aid in reconstructive foot...

AO Principles In 1958, the AO formulated four basic principles, which have become the guidelines for internal fixation.1, 2 The principles as applied to the Variable Angle LCP Forefoot / Midfoot System 2.4 / 2.7 are as follows: Anatomic reduction The use of variable angle locking technology allows fragment specific fixation by providing the flexibility to lock screws in trajectories that can diverge from the central axis of the plate hole. Variable screw angles provide fixation options for a variety of fracture patterns. Stable fixation Variable angle locking screws create a locked...

Indications The Straight Fusion Plates, T-Fusion Plates, L-Fusion Plates, Cloverleaf Fusion Plates and X-Plates of the Variable Angle LCP Forefoot / Midfoot System 2.4 / 2.7 are indicated for fractures, deformations, revisions and replantations of bones (e.g. tarsals, metatarsals and phalanges) and bone fragments, particularly in osteopenic bone.

Controlled Compression Technique The plates included in the Variable Angle LCP Forefoot / Midfoot System 2.4 / 2.7 aid in reconstructive foot surgery by allowing controlled compression with the use of compression wires and compression forceps. Compression feature – Allows for up to 4 mm of compression – Tactile compression – Designed within the plate to minimize additional soft tissue dissection – Allows for final screw fixation after compression is achieved Compression wires – 1.6 mm diameter, 150 mm overall length – Seven thread lengths: 10, 15, 20, 25, 30, 35 and 40 mm – Stop feature...

1 Position plate Place the plate on the bone, ensuring that the plate is placed appropriately according to the specific procedure. 2 Insert compression wires Instrument 03.211.410.01– Compression Wire л 1.6 mm, 03.211.440.01 length 150 mm, thread length 10 – 40 mm Estimate the appropriate thread length needed for the plate and bone combination. Bicortical fixation is recommended. Using a wire driver, insert the compression wire through the compression wire hole and through both bone cortices. Important: To minimize stripping of the bone threads, slow the insertion once the spherical stop of...

Controlled Compression Technique Compress using forceps with Compression Wire Move the ratcheting switch so the forceps ratchet when clos- ng preventing the spring from opening the forceps. Place the compression forceps in position, ensuring that the arms are around the compression wire spheres. Compress by squeezing the handles. Important: Compression is tactile, but be careful not to over compress. This may cause the compression wires to strip out When the ratcheting mechanism is in the correct position, compression can be maintained without holding the forceps. O This leaves the hands...

Screw Insertion Techniques The plate holes of the Variable Angle LCP Technology 2.4 / 2.7 accept 2.4 mm and 2.7 mm Variable Angle (VA) Locking Screws. Screws can be inserted using two different techniques: – Variable angle technique – Pre-defined nominal angle technique Variable angle technique To drill variable angle holes at a +/-15° deviation from the nominal trajectory of the locking hole, insert the tip of the conical VA-LCP drill sleeve (03.211.003 / 03.110.023) and key into the cloverleaf design of the VA-LCP hole. VA-LCP drill sleeve, conical, for Drill Bits (03.211.003/03.110.023)...

Prepare joint surface Remove the cartilage and prepare the joint surface for an arthrodesis. The surface of the joint can be manipulated to achieve the desired correction. Open osteotomy Create an osteotomy starting from the medial side. Do not cut through the bone leaving the lateral cortex intact. Reduce fracture O Reduce the fracture under the image intensifier and if neces- sary, fix with Kirschner wires or reduction forceps. The reduc- tion method will be fracture-specific.
