My current research interests include; (1) metabolic bone markers in diabetic patients to identify risk factors for Charcot neuroarthropathy, (2) sports injuries, specifically the mechanism of injury for the 5th metatarsal “Jones” fracture and (3) the biomechanics of passive and active foot arch control.
I continue my research interests in the areas of metabolic bone markers in diabetic patients to identify risk factors for Charcot neuroarthropathy, the influence of biomechanical factors on the management of the proximal 5th metatarsal Jones fracture, and medical education looking at self-assessment in determining student confidence in the clinical curriculum.
My research interests include evaluating bone quality in the diabetic patients with Charcot neuroarthropathy, sports injuries and podiatric medical education research. Approved projects currently in progress are: (1) Dissimilarity in Charcot ankles versus Charcot midfoot and (2) The effect of metatarsus adductus on bone healing in the proximal fifth metatarsal Jones fracture. I am in the design phase of an education research project looking into the correlation between research curriculum in podiatric medical school and research product in during residency training. Podiatric medical students are involved in all of these studies.
My interest is in evaluating bone quality in the diabetic. Preliminary studies have been completed on vitamin D levels and bone density in diabetic patients with and without Charcot neuroarthropathy and non-diabetics. The summer project is to develop a grant to expand the work already completed and explore additional factors to evaluate bone density for these subject groups.
Metatarsus adductus appears to be a risk factor in individuals sustaining proximal diaphyseal-metaphyseal fifth metatarsal fractures. The typical treatment for these fractures is surgical reduction using an intramedullary screw. The metatarsus adductus angle will be determined from existing x-rays of patients evaluated and treated by DMU Foot and Ankle Institute clinicians or community podiatrists for these fractures. The radiographic healing time will be determined by following serial radiographs. The purpose of this retrospective study is to determine the relationship between the healing times of these fracture and metatarsus adductus.
Assessment of bone quality in diabetic patients with and without Charcot neuroarthropathy. We have identified decreased levels of vitamin D in diabetic patients with a more pronounced deficiency in patients with diabetic Charcot foot disease. Bone density evaluation (PIXI scan) confirms decreased bone mass in the feet of diabetics.
