Midtarsal Joint Biomechanics: Theory, Research and Clinical Applications

The midtarsal joint (MTJ) consists of the talo-navicular joint and calcaneo-cuboid joint. Together these two joints provide the MTJ with sufficient compliance to allow the metatarsal heads to remain plantigrade on a variety of surfaces and also to allow the longitudinal arch to resist large magnitudes of ground reaction force during a wide range of weightbearing activities.

This talk will describe in detail the anatomy, biomechanics and clinical applications around the MTJ so that clinician have a better understanding of how selected interventions may affect the function of this important joint in the foot.


Kevin A. Kirby, DPM

Dr. Kevin Kirby graduated from the California College of Podiatric Medicine in 1983 and completed his first-year surgical residency at the Veteran’s Administration Hospital in Palo Alto, California in 1984.  He spent his second post-graduate year doing the Fellowship in Podiatric Biomechanics at CCPM where he also earned his MS degree in 1985.

Dr. Kirby has authored or co-authored 29 articles in peer-reviewed journals, has authored or co-authored six book chapters, and has authored five books on foot and lower extremity biomechanics and orthosis therapy, all of which have been translated into Spanish language editions.  He has invented the Subtalar Joint Axis Palpation Technique, the Anterior Axial Radiographic Projection, the Supination Resistance Test, the Maximum Pronation Test and the Medial Heel Skive and Lateral Heel Skive Orthosis Techniques.  He has also created and developed the Subtalar Joint Axis Location and Rotational Equilibrium Theory of Foot Function, the Longitudinal Arch Load-Sharing System Theory of the Foot, the Longitudinal Arch Auto-Stiffening Theory of the Foot, and  has co-developed the Subtalar Joint Equilibrium and Tissue Stress Approach to Biomechanical Therapy of the Foot and Lower Extremity.  He has lectured internationally on 48 occasions and has also lectured extensively throughout the United States on the foot and lower extremity biomechanics, foot orthosis therapy, sports injuries, running and running shoe biomechanics and the biomechanics of foot surgery.

Dr. Kirby is a member of the editorial advisory board for the Journal of the American Podiatric Medical Association and is currently an Adjunct Associate Professor in the Department of Applied Biomechanics at the California School of Podiatric Medicine. He is also Director of Clinical Biomechanics for Precision Intricast Orthosis Laboratory and is the former Chairman of Podiatric Surgery at Methodist Hospital in Sacramento, California.  Dr. Kirby has had a full-time podiatric biomechanics and surgical practice in Sacramento for over 34 years.
