External Locking Fixation for Tibia Fractures


Project ID:  D2018-25



Extra-articular tibia fractures which include proximal tibia, diaphysis and distal tibia fractures are often associated with many serious complications and result in disability. Current treatment methods include the use of an intramedullary rod, an internal locking/unlocking plate, and an external fixator. However, these treatment methods have significant drawbacks including the invasiveness of the surgical procedures, delayed union or non-union, infection and, often, the requirement of a second procedure to remove nails or screws. There is, therefore, a great need for improving the treatment of these tibia fractures. 


Invention Description

Researchers at the University of Toledo, led by Dr. Jiayong Liu, have developed an external locking fixation device for treating distal tibia fractures using a relatively minimally invasive approach and without the need for further major invasive procedures.



•       The locking fixation device may be used for the treatment of extra-articular tibia fractures



•       The device may provide a better biological environment for fracture healing since it is minimally invasive and does not disrupt the underlying cortical bone perfusion any further

•       The device may also provide a better biomechanical environment for healing since the locking plate and screw systems do not require precise adaptation of the plate to the underlying bone. The fixation force may distributed to multiple screws

•       The device may have significantly lower revision rates and better fracture union rates

•       The device may be adjustable and low-profile creating a more ‘universal’ fit and concealability under clothing

•       The device may be easily removed in an outpatient setting and does not require a second major procedure
