Tibial fracture is one of the most common injuries in the lower body, and it is usually caused by great forces such as motorcycle or sports accidents. Its treatment can be classified into two types, operative and non-operative treatment. An example of non-operative treatment is cast treatment, while operative treatments include treatments with nails, plates, or external fixators. More complex fractures tend to require an external apparatus called the Taylor spatial frame. Biomechanics Lab of FTMD ITB has started a project on developing an affordable Tayllor spatial frame. prototype has been manufactured, however, an experimental analysis related to the Taylor spatial frame mechanical behavior such as its axial stiffness is yet to be done. Taylor spatial frame consists of rings, struts, a universal joint, and a fixation component such as half pins or wires. A compression test on the device’s SS316L wires is conducted to calculate its axial stiffness. The Taylor spatial frame is modeled as a single ring with wires attached to the ring and implanted to the tibia. The wires are subject to pretension prior to the loading and are crossed at different divergence angles. The displacement on the wires is then analysed. The relationships of load, pretension, wire diameter, divergence angle, and displacement of the wires are acquired in the form of graphs and equations. This research led to the conclusion that wire pretension, diameter, and divergence angle contribute to the increase of axial stiffness of the Taylor spatial frame. Increasing the wire diameter, pretension, and divergence angle decreases the displacement of the wires.
