My laboratory is a group of approximately six to ten people people working in three distinct areas: Pharmaco-aduvant therapy for orthopaedic neurotrauma; trauma outcomes assessment, and biomechanical assessments of cartilage relaxation. We are currently engaged in multiple research projects in the clinical, translational, and basic science realms. We have an approach that allows multiple teams to approach distinct projects in neuroregeneration, large-scale population studies of orthopaedic outcomes and basic biomechanics.
Our neuro-scientific research is centered on the effect of erythropoietin (EPO) and 4-aminopyridine (4AP) on regenerating peripheral nerve function after severe peripheral nerve trauma. Our work is motivated by the potent effect which EPO and 4AP have on injured nerves. These effects include the promotion of myelin production, a holy-grail in peripheral nerve injury science. We have found potent and lasting effects on the structure of the nerve at the sites of injury, which are coupled with demonstrable changes in limb function. So far, we have demonstrated that a potentially large group of agents, already approved for use in humans by the Food and Drug Administration (FDA), may hold the potential to accellerate recovery after neurotrauma. In the case of several of these agents, translation to the clinic is currently underway using Investigational New Drug approval which we have been granted from the FDA. If successful, these agents will offer some of the only treatments for peripheral neurotrauma available. Our efforts are therefore directed on further study on mechanistic detail of neuroregenerative, myeloprotective, and functionally supportive treatments while at the same time conducting first-ever clinical trials on these same agents in humans.
In parallel with our translational work, my group has grown to include several members of the surgical community interested in examining surgical and trauma outcomes. We have focussed on approaches that combine large-scale big-data with small scale local chart-based validation. Thus far, we have been able to contribute studies on orthopaedic trauma outcomes centered on the quintessential hip-fracture. What grew out of a team diversion has become a full-fledged Center for Orthopedic Population Studies (COPS), which has used large database programming to produce several critical manuscripts documenting key elements underpinning cost, length of stay, and mortality after trauma.
Finally, we have delved into preliminary work on biomechanics analysis of joint reaction force measurements using the novel method of cartilage relaxation (technique, CRT). We have shown that measurements of the minute forces required to relax small and even large cartilage surfaces in joints can be measured, even in the absence of disruptive interposition of sensors. The dissection of stabilizing soft tissue to interpose such sensors alters the same forces which are to be measured. Using principles from the science of non-destructive evaluation derived from engineering methods, we have endeavored to accurately measure these minute forces without destructive interposition of sensor material - a key limitation of current methods. Thus far, this program has produced several significant contributions that center on measurements in small joints, where the dissection to interpose tissue would naturally yield spurious results.
Each of these programs has been built through collaboration with co-investigators and has garnered significant extramural funding. Each also represents a collaboration where, my role has been founding and also fostering a group which shares ownership and responsibility for funding applications, publications, successes and failures. The process of beginning and supporting independent, programmatically funded research programs is the primary interest which has fueled my work.
