The Double Dynamic Martin Screw (DMS)

The scope and importance of hip fractures is almost incomprehensible. With a world wide incidence of close to 2 million cases per year, these fractures pose a daunting challenge to our ability to affect and treat this epidemic. The incidence of these fractures is predicted to grow to 6 million in 2050 including a near term baby boom spike. Add the hospital mortality rate of up to 4% and the one mortality of from 8% to 20% and the life ending effect of these fractures becomes a glaring reality. Of those who initially survive their fracture, about 50% never walk the same again. The social problem in the care of these elderly people is enormous. Of course, any real solution to this problem will include education, prevention, surgical and hospital treatment protocols, long term rehabilitative efforts, social - justments and a generous contribution of money. This publication is primarily directed to the amplification of a new treatment modality that addresses only a fraction of the problem. It is, however, a quantum leap in the evolution of fixation with compression hip screws which are still the gold standard for surgical stabilization of pertrochanteric hip fractures. The Dynamic Martin Screw (DMS) addresses the issue of adjustability of the fixation angle with appropriate mechanical strength characteristics that were la- ing in its historical predecessors.

Basics for operative treatment of proximal and distal femur fractures:

• Clear surgical indication
• Short planning and preparation < 24 h
• Full weight bearing osteosynthesis
• Early mobilisation and physiotherapy

 In comprehensive form the book presents the usage of a meanwhile well installed implant (DMS) for osteosynthesis technique in the peritrochanteric region. The „double dynamic" stabilization (sliding tongue principle and angle adapted contoured fit) means a state of the art fracture treatment procedure. It is a convincing alternative to achieve a biological osteosynthesis at the femur. The system includes an infinitely adjustable, flexible angle, dynamic plate with a tubular distal part.
