BACKGROUND Biomechanical models have been used to study stress in the metatarsals, subtalar motion, lateral column lengthening and subtalar arthroereisis. Posterior tibial tendon dysfunction has been associated with increased loads in the arch of the acquired flat foot. We examine whether a 10 millimeter (mm) medial displacement calcaneal osteotomy and(More)
A biomechanical model of the foot is developed and analyzed to determine the distribution of support under the metatarsal heads, the tension in the plantar aponeurosis, and the bending moment at each of the joints of the foot. This model is an extension of our earlier work to include the role of muscles, tendons, and ligaments. Two cases are presented: in(More)
A three-dimensional biomechanical model was used to calculate the mechanical response of the foot to a load of 683 Newtons with the subtalar joint in the neutral position, at five degrees of pronation, and at five degrees of supination. Pronation causes the forefoot to evert, increasing the load borne by the first metatarsal. This results in a 47% increase(More)
BACKGROUND Biomechanical models have been used to study the plantar aponeurosis, medial arch height, subtalar motion, medial displacement calcaneal osteotomy, subtalar arthroereisis and the distribution of forces in the normal and flat foot. The objective was to examine the hypothesis that increased load on the medial arch in the adult flat foot can be(More)
A kinematic analysis of the temporomandibular joint (TMJ) is developed to determine the range of motion of the mandible during normal opening and during special motions required for arthroscopic surgery. The translation of the mandible is restricted by the constraint of the ligaments. By accounting for the maximum allowable stretch of a ligament, limits of(More)
We present a mathematical model to determine the contribution of each muscle acting on the mandible in the development of a given bite force. We give special attention to the representation of the widely radiated temporalis and account for the attachment of the external pterygoid to the capsular ligament. An optimization technique based on minimizing the(More)
