LCP Superior Anterior Clavicle 3.5
The precontoured LCP anterior superior clavicle plate system 3.5 represents another important group of anatomically preshaped plates for the clavicular bone. It is indicated not only for the fixation of fractures, but also for malunions and nonunions of the clavicle.
Anatomical precontouring implies the need for a left and right version. Additionally, the plate system provides different lengths. These various plate lengths accommodate a variety of different fracture patterns, especially fractures with a lateral extension or fractures of the lateral clavicular third with or without ligamentous involvement.
Plates with a lateral extension come in sizes of 38 holes, plates without lateral extension in sizes of 68 holes. The complete plate system is available both in stainless steel or titanium.
Notches in the plate aid additional contouring. New bending pliers provide further aid in adapting the plate to the bone. Diverging and crosshatching screw patterns in the lateral end help in creating a stronger construct. The plates use 3.5 mm locking screws in the shaft and feature 2.7 mm locking screws in the lateral extension also allowing for an increased number of screw positions in the lateral extension.
Static and dynamic mechanical tests proved two times the yield strength of the new anterior superior clavicle plate compared to the LCP reconstruction plate 3.5, both under a dynamic compression load as well as under torsional load.
Surgery is very straight forward as in most cases, no or only minor additional contouring of the plate is required, thus minimizing surgery time. The plate has already proven itself in the field and has become our favorite implant for clavicular surgery requiring a plate.
A 21-year old male fell on the right shoulder when playing soccer. He sustained a cavicular shaft fracture type 06 A3 (OTA classification) with dislocation of shaft width and shortening of around 2 cm.
