Characteristics of the MPHT system
The proximal humeral nail (MPHT: multilocking proximal humeral treatment nail) treats mainly the fractures of the humeral head and the diahpyseal fractures directly below the humeral head. The fracture fragments can be fixed in four directions at the same time, allowing the fixation of tuberculum maius, tuberculum minus and the cartilaginous head. Solid and cannulated versions are available in the product range. A targeting arm facilitates the distal locking.
The nail was designed according to the three-dimensional characteristics of the bone anatomy. Its proximal end is available with two diameter sizes. The shaft, which fits to the diaphyseal part, is thinning. In order to enable an easy implantation, the nails are curved, however they can be used universally for the left - and for the right hand side. Screw heads ensure a good pressure-distribution, preventing the head from further ruptures.
