Schanz Screws are available in various Types, lengths and diameters.
Types: Self Tapping, Self Drilling, Tapered Threaded
Diameters: 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm
Lengths: 60 mm to 300 mm
Schanz Screw Self Drilling has been specifically designed to optimise the bone/pin interface to reduce the occurrence of pin-tract related complications in external fixation.
The unique design of Schanz Screw Self Drilling reduces heat generation and insertion torque while improving pullout resistance in cortical and cancellous bone
Schanz Screw is intended for use with an external fixation system for fracture fixation (open or closed); pseudoarthrosis or nonunion of long bones; limb lengthening by epiphyseal or metaphyseal distraction; correction of bony or soft tissue deformity; correction of segmental bony or soft tissue deformity; correction of segmental bony or soft tissue defects; and joint arthrodesis.
The chosen diameter of the Schanz Screw depends on the system that is selected for a particular fracture and on the bone size. For example, for a tibial fracture, Schanz Screw with a diameter of 5 mm are used (2.5 mm Kirschner wires or threaded pins are used for the small fixator).
