Foot problems associated with older patients. A focused podogeriatric study.

The authors report on a 3-year prospective program that included foot-health education and an initial assessment of foot problems in an older population. The program represents a cooperative effort by the Philadelphia Corporation for Aging and the Pennsylvania College of Podiatric Medicine to enhance the quality of life of older citizens. The results show that foot problems are prevalent among older patients. The program also refined a protocol that can be applied in other settings.

Geometric models that classify structural variations of the foot.

The author presents a description of three geometric models to serve as a framework for establishing a numerical classification system of unlimited refinement for structural variations of the foot and foot types. Such a classification system may identify different forms (foot types) that may be closely aligned to complex movements of the foot (dynamic foot function). This may help in the diagnosis and treatment of biomechanical disabilities. Clinical evaluations are based on radiographic landmark data from weightbearing radiographs.

Pathomechanical metatarsal arc: radiographic evaluation of its geometric configuration.

A total nonlinear relationship among all five metatarsals is presented in this article. This relationship is an equation whose graph is a conic curve. The metatarsal arc is defined as a conic curve that has a unique numeric value, its eccentricity. Thus, each metatarsal arc variation has a unique eccentricity value, an axis location value, and a coefficient of variation value. It is assumed that many of these metatarsal arc variations are pathomechanical, and that an optimal arc exists. A small sample yielded numeric values that appear to be related to the degree of pathomechanical variation. Based on a small sample, clinical experience, and a numeric classification that is theoretically attractive, it is recommended that the surgeon plan each case of forefoot surgery so that these numeric values are given due consideration in the establishment of a geometric configuration for the metatarsal arc. To obtain these numeric values, the surgeon can learn to analyze the radiographs mathematically or submit them to someone who can.
