Abstract

The plantar aponeurosis is a ligamentous structure that extends from the calcaneus to the proximal phalanges. Under tension, it functions to support the longitudinal arch, supinate the rearfoot, and stabilize the digits against the ground. The anatomy and biomechanics of the plantar fascia [...] Read more.

The plantar aponeurosis is a ligamentous structure that extends from the calcaneus to the proximal phalanges. Under tension, it functions to support the longitudinal arch, supinate the rearfoot, and stabilize the digits against the ground. The anatomy and biomechanics of the plantar fascia and plantar aponeurosis, particularly their role in digital stabilization, are reviewed. A case is presented showing a patient who developed hammer toes as a postoperative complication after having a portion of the plantar aponeurosis removed. Full article

The authors attempt to assess the relationship between exercise, diabetes, and bone metabolism. An animal model system was developed to study the relationship. Animals given streptozotocin to induce a type I diabetic state show elevated plasma glucose and triglyceride levels and a decrease in body weight. Analysis of femurs revealed alterations in copper, phosphorus, and zinc levels in animals with diabetes compared with controls. Mineral analysis of femurs from diabetic animals placed on an exercise regimen revealed values closer to control levels. Full article

A methodology for measuring the kinematic parameters of joints in vivo has been refined using the technique of computerized three-dimensional reconstruction from magnetic resonance images. A research protocol has been developed to establish a classification of normal and pathologic foot function that will have broad clinical application. Development of algorithms for a computer-directed program that can predict resultant kinematics and joint morphometry for a given osteotomy or osseous remodeling procedure will assist the surgeon in preoperative surgical planning.

The authors present a case report showing successful autogenous calcaneal bone graft stabilization of a first metatarsal closing base wedge osteotomy nonunion. The authors discuss the complications and clinical sequelae associated with first metatarsal base wedge osteotomy nonunions. The patient's clinical presentation, surgical procedure, and postoperative course are discussed. Comparative preoperative and postoperative objective gait analyses are presented. This approach to first metatarsal nonunion salvage appears to be clinically successful with a 15-month follow-up period. Full article

Foot Type Biomechanics. Comparison of Planus and Rectus Foot Types

The basic premise central to the diagnosis and treatment of most mechanogenic foot and ankle pathologies is that a given foot will display a characteristic function depending on the biomechanical alignment of the hindfoot and forefoot. However, the effects of foot type on [...] Read more.

The basic premise central to the diagnosis and treatment of most mechanogenic foot and ankle pathologies is that a given foot will display a characteristic function depending on the biomechanical alignment of the hindfoot and forefoot. However, the effects of foot type on an individual's ability to perform comfortable cadence locomotion have not been scientifically proven. Therefore, this study was conducted on 21 healthy, young subjects (10 subjects with planus foot type and 11 subjects with rectus foot type) to test whether different foot types yield distinguishable foot functions. New methods were developed to quantify biomechanical foot function during posture and comfortable cadence locomotion. The results of the study indicate that individuals with planus and rectus foot types show statistically significant differences in the biomechanical function of the foot. Full article

A new method of measuring the kinematic parameters of joints has been developed. This article describes the procedure, using tarsal joints as examples. The method uses the technique of computerized three-dimensional reconstruction from magnetic resonance images, taken at regular intervals throughout a foot's range of motion. From these reconstructions, various kinematic information, such as orientation of instantaneous axes, amounts of rotation, amounts and direction of translation, and bony contact areas, is derived. The method is noninvasive and can be applied to individual subjects or patients. Full article
