LCP Hook 3.5 for distal tibia and fibula

media-102614

Simple olecranon fractures and osteotomies as well as avulsion fractures of the medial and lateral malleolus treated with tension-band fixation are often followed by complications, especially with minimal bone stock/poorly mineralized bone, such as loss of reduction, migration of K-wires, and hardware prominence.

The LCP hook 3.5 enables tension-band plating with use of 3.5 mm screws. The hooks aid fixation of small bone fragments and increase stability. Elongated LCP holes make the plate and its fixation more flexible and allow for controlled compression. The spring effect facilitates reduction and a stable tension-band technique. Its flexible one-third tubular plate design provides an anatomical fit and its low profile minimizes hardware prominence.

The LCP hook 3.5 was primarily intended for treatment of simple fractures of the olecranon and osteotomies of the olecranon for distal humerus fracture treatment creating compression with the long oblique 3.5 mm lag screw. But it has shown its benefits also in avulsion fractures of the distal tibia and fibula.

A 20-year-old construction worker fell from a 3 m height. He sustained a typical posterolateral impression and flake fracture of the talar dome.
