Summary

The objective of this study is to develop methods for using forces measured on circular external fixators to predict the state of individual patient's healing of severe tibial fractures and defects.

Detailed description

Patients receiving external fixators for tibial fractures and defects will be recruited. Normal struts on the device will be substituted with similar but instrumented struts which enable force measurement. During clinical visits, forces in the fixator, plus foot forces, will be measured during ambulation. Changes in force measurements across treatment and bone healing will be analyzed. Severe fractures in the lower limb are associated with high energy trauma in both civilian and military patients,and are sometimes treated with external fixation devices to stabilize the bone until healing has occurred. The devices are kept on the patient for up to a year or more at significant cost, intrusiveness, and risk of infection. The clinician must decide when to remove the device such that adequate healing has occurred and the bone will not re-fracture, but healing rates are variable and x-rays can be misleading. The clinician must also identify when a patient is starting to progress poorly and an early revision surgery is needed to prevent further complications. The investigators' goal is to develop novel approaches for instrumenting and collecting mechanical data from orthopaedic braces and devices, and identifying new methodologies for interpreting this large volume of functional data for optimizing personalized treatment. The present study is focused on external fixators. Strain gauges will be adhered to the fixators so that fixator forces can be measured during clinical visits. In this pilot study the investigators will develop methods to predict healing based on these measured forces.
