Medartis | Olecranon System 2.8

Designed to perform.

The Medartis Olecranon System 2.8 offers a range of plates with innovative fixation concepts that may help reduce soft tissue irritation and therefore reduce the rates of hardware removal surgeries. ^[1]

Fixation Options

The low profile 2.8 TriLock Olecranon Double Plates are designed to fix complex olecranon fractures without interfragmentary support. Their innovative lateral positioning allows for muscular soft tissue coverage and an increased amount of screws to hold small proximal fragments. ^[2]

The 2.8 TriLock olecranon tension plate was developed as a replacement of the classic tension band wiring. The low-profile plate is very thin entailing limited hardware prominence ^[3] and can withstand tensile forces. It is indicated for fractures and osteotomies of the proximal ulna with interfragmentary support.

For complex olecranon fractures, including Monteggia fractures, Medartis includes in the portfolio the 2.8 TriLock Dorsal Olecranon Plates, featuring an excellent anatomical fit and dedicated pre-angled screw holes to enable specific screw trajectories aiming into the coronoid. Plates are available in various lengths with three proximal end configurations. Medartis provides various olecranon fracture treatment options offering versatile solutions tailored to fracture patterns and surgeon preferences.

Highlights

Low plate profile and high rotational stability due to biomechanically favourable posterolateral and posteromedial plate position
Plates can be covered with soft tissue (anconeus muscle and flexor carpi ulnaris muscle), thereby reducing the occurrence of wound healing problems and the likelihood of hardware removal ^[1,2]
High number of screw options enables stable fixation particularly of small proximal fragments ^[2]
High primary stability due to screw position orthogonally to the direction of the pulling force of the triceps brachii muscle ^[2]
Easy bending to adapt to the individual anatomy of the patient

Highlights

Developed as a replacement of the classic tension band wiring
The low-profile plate is very thin entailing limited hardware prominence ^[3] and can withstand tensile forces
Two cross-fracture lag screws provide primary compression and fixation ^[3]
Uniform and controlled compression of the fracture with lag screws allows for mobilization as early as possible ^[3]
Solid anchoring of the tension relief even in osteoporotic bone reduces the risk of fracture dislocation ^[3]

Fractures of the proximal ulna: current concepts in surgical management.
Siebenlist, S., Buchholz, A., Braun, K. F.

2019

EFORT Open Reviews

In this review, Siebenlist et al describe the current treatment options in surgical management of proximal ulnar fractures. The authors conclude that these fractures require precise planning. The exact reconstruction of the bony anatomy of the ulna including the coronoid process is the primary goal in any operative strategy accompanied by radial head repair/replacement. They also highlight that "... the application of an adequate treatment algorithm and the use of modern implants for fracture fixation have resulted in better functional outcomes in recent times".
