Talar Anatomy and Subtalar Joint Alignment on Weight-Bearing Computed Tomography

Sagittal subtalar and talocrural joint assessment with weight-bearing fluoroscopy during barefoot ambulation.

BACKGROUND Identifying talar position during ambulation has proved difficult as the talus lacks palpable landmarks for skin marker placement and more invasive methodologies such as bone pins are not practical for most clinical subjects. A fluoroscopic motion system was used to track the talus and calcaneus, allowing kinematic analysis of the talocrural and subtalar joints. METHODS Thirteen ma...

Comparison of Double and Single Leg Weight-Bearing Radiography in Determining Knee Alignment

  Background: Knee malalignment is an important modifiable cause of osteoarthritis (OA). Surgical therapeutic procedures depend on proper knee alignment assessment. The purpose of this study was to compare knee alignment parameters between double and single leg weight-bearing radiographs and to evaluate the reproducibility of inter- and intra-observer measurements. Methods: One hundred eight p...

Weight-bearing parallel-beam scanography for the measurement of leg length and joint alignment.

Is it important to position foot in subtalar joint neutral position during non-weight-bearing molding for foot orthoses?

When taking molds for foot orthoses, it is accepted practice to position the subtalar joint in its neutral position. However, foot orthoses have no contact with the talus, and this leads to a hypothesis that as long as there is correction available to appropriately align the forefoot relative to the hindfoot when taking a mold, changes in subtalar joint angles do not lead to significant alterat...

Subtalar Joint Arthrodesis

The following investigation consists of a retrospective review of more than 50 patients having undergone an isolated subtalar joint fusion for the correction of the multi-planar flatfoot deformity. These results support the notion that the isolated subtalar joint fusion can provide enhanced stability in selected patients with painful flatfoot deformities. Radiographic evaluation & chart review ...
