improved tto instrumentation

Warrick Bruce has designed two new instruments to make the TTO procedure easier and to eliminate some of the practical difficulties encountered using the original instrumentation. The new combined Osteometer and Saw Guide interlock to become a single instrument which is much easier to manage than the original two separate instruments. The thumbscrew locks the Osteometer onto the Saw Guide for secure accurate osteotomies. The Osteometer still has holes for fixation to the tibia using 1.6 arthrodesis wires. Alternatively Warrick’s second new instrument ‘the Clasper’ may be used to lock the osteometer onto the tibia prior to cutting. The ‘Clasper’ has an additional role in that it is used to replace the kern bone holders in the original technique. The ‘Clasper’ grasps the tibia crest prior to closure and incorporates location holes for the very large fragment forceps to lock into. The ‘Wedgie’, used for manipulating the three osteotomies remains unchanged.
