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 lacking in its historical predecessors.
It exhibits the unique ability to allow the surgeon to improve the reduction to a more advantageous valgus angle even after it is rigidly attached to the femur. This provides a more stable construct that will allow for a more successful recovery of the patient to their previous ambulatory life.
In addition, the device is ideally suited for a new challenge in hip fractures, the MRI fracture. These are undisplaced fractures diagnosed almost entirely by magnetic resonance imaging. Since they are, by definition, undisplaced, the infinite adjustment of the femur neck angle of this device is the perfect solution.
The variable angle system has been adapted for paediatric use. While useful for fracture fixation, it is an excellent option for fixation in the varus femoral osteotomy for dysplastic hips and subluxation in children with cerebral palsy.
Further on the supracondylar version is very valuable for distal femur fractures. The supracondylar version with cable extraordinarily is suited for the devastating periprosthetic femoral fracture in the total hip patient. This situation, by the way, is a new epidemic!
