LCP Hook 3.5

Norbert Südkamp, Ralph Hertel, Martin Hessmann, Pol Rommens

The LCP Hook 3.5 enables tension-band plating with use of 3.5mm screws. The Hook 3.5 was primarily intended for the treatment of simple fractures of the olecranon as well as osteotomies of the olecranon following distal humeral fracture. It has also shown benefits in avulsion fracture of the distal tibia and fibula.

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. The flexible one-third tubular plate design provides an anatomical fit and a low profile minimizes hardware prominence.

Simple olecranon fractures and osteotomies as well as avulsion fractures of the medial and lateral malleolus treated with traditional tension-band fixation methods are often followed by complications. This is especially evident in patients with poor bone stock and complications include loss of reduction, migration of K-wires and hardware prominence. The LCP Hook 3.5 is a satisfactory alternative fixation.
