LCP Hook Plate 3.5. The simple fixation system for tension band plating. Features and Benefits Tension band plating – Elongated LCP-holes make the plate and its placement more flexible and allow for controlled compression – The spring effect facilitates reduction and a stable tension band technique – Hooks allow optimal fixation in small bone fragments and increase stability – LCP technology for increased stability in osteoporotic bone Simple and proven solution – State of the art solution for a commonly performed one third tubular plate modification* – Intuitive and easy-to-perform...

AO Principles In 1958, the AO formulated four basic principles1, which have become the guidelines for internal fixation: Anatomic reduction The plate with its hooks, its pre-bent shape and its elongated combi-holes facilitates anatomic reduction. Stable fixation The plate hooks and the spring-effect on the dorsal cortex provide an optimal tension band mechanism. Preservation of blood supply The plate design preserves the blood supply through minimal plate to bone contact and due to a reduced number of screws. Furthermore, the plate design permits indirect reduction, thus resulting in...

Implantation Notes – Familiarity in the use of LCP plates or instruction from an experienced surgeon is recommended (see the Synthes Technique Guide for LCP Plates, Art. No. 036.000.019). – This technique describes the application of the LCP Hook Plate 3.5 on the olecranon. The technique can also be used in a similar manner on the distal tibia and the fibula. 1 Position the patient Place the patient in lateral decubitus with the elbow flexed over a side rest. A small padded table can be placed under the forearm to support the elbow in extension if necessary. 2 Surgical approach Perform a...

Implantation 3b 1 For osteotomies Instrument 292.560 Kirschner Wire л 1.6 mm with double tip, length 150 mm, Stainless Steel Perform an incomplete osteotomy of the dorsal cortex of the olecranon using a thin oscillating saw blade to allow access to the distal humerus (1). Complete the osteotomy with a chisel in order to obtain an interdigitating fracture line. The fracture line should ideally run through the bare area of the sigmoid notch (2). 2 8 Synthes LCP Hook Plate 3.5 Technique Guide

Following the osteotomy, the olecranon fragment is tipped over to the lateral side. 3 Protect the ulnar nerve on the medial side as well as the muscular branch to the anconeus on the lateral side. Perform surgery on the distal humerus as required. Insert a 1.6 mm double-tipped Kirschner wire into the proximal olecranon fragment (3). The wire is inserted from distal to proximal starting close to the articular surface and ending at the distal insertion line of the triceps. Reduce the olecranon. Check for anatomic interdigitation. Insert the Kirschner wire until it passes the cortex of the...

Implantation 4 Pre-drill holes for hooks Instrument 310.210 Drill Bit л 2.0 mm, length 125/100 mm, 2-flute, for Quick Coupling Drill two holes for later hook placement using the plate as a guide. The holes should lie about 4 mm proximal to the insertion line of the triceps and be well centered over the olecranon. Note: The holes are drilled through longitudinal splits in the tendon fibers. 10 Synthes LCP Hook Plate 3.5 Technique Guide
