- the present invention is easily applicable and removable. It is light as possible, and strong enough as necessary. It requires the least instruments during application, and can be applied in a single or multiple plan. Due to being multifunctional; lengthening- shortening (compression-distraction), rotation (internal-external rotation), angulation, or correction (varus-valgus, flexion, extension), temporary or therapeutic fixation, traslation can be perfomed with it, and it can be combined with other systems. With the invention, functions can be done at one time or gradually in a controlled way. Functions can be perfomed seperately or together. When one fuction is activated in the system, the other functions are not affected from that.
- the present invention consist of one main body, two monoblock pin holders, adaptable free pin holder (12) and pins, and it is designed in different sizes for femur, tibia and humerus.
- MAMEF main body consist of two parts which are interlocked with screw system (threaded system); lenghtening-shorthening (compression-distraction) functions are performed here by the help of the system preventing rotation, without the need for any additional part; it has a total of twelve pin insertion holes (14), as being six pieces each (6+6) on the front and the back; two pins inserted sequentially in the front and the back grooves are positioned at an angle of 15 degrees between themselves.
- MAMEF pin clamps have monoblock cylindirical structures, and they are fixed to MAMEF body with a special connection system consisting of a sphere (1) and pins (2).
- Pin clamps on both ends of MAMEF have fourteen different pin inserting holes as being six horizontal (9), four proximal oblique (16) and four distal oblique holes (16).
- Six pins can be placed in each pin clamp at the same time. Pins can be placed on them at different angles on the same plane at the same time. They allow pin inserting on more than one plane.
- Each pin is fixed with a setscrew (10).
- MAMEF pin clamps are moved at angles according to their main body axes, by a special connection system consisting of spheres (1) and pins (2).
- Both ends of MAMEF have 360 degree rotations, a total of 60 degree flexion-extension as being 30 degree each (30+30), a total of 60 degree varus- valgus as being 30 degree each (30+30).
- Functions can be performed separately or together, at the same or different time, at one time or gradually in a controlled way.
- Adjustable free pin clamps (12) can be placed in all pin holes and grooves in the system. They can be placed on three plans, at 360 degrees, at any desired angle, and at any quantity.
- Pins can be made of titanium or stainless steel. Their tips are designed as tapered and threaded. They have different diameters, lengths and thread lengths for femur, tibia and humerus. They can be placed in one or two cortex. Pins for translation are the ones having threaded parts starting after 2cm from the smooth tip, and continuing 4 cm.
