To quantitatively evaluate the shape of the transverse arch in the forefoot with hallux valgus, a method for axial imaging and analysis of the forefoot has been developed. A foot was imaged at 30 degrees of flexion. A two-dimensional coordinate system was established by drawing a vertical line on the X-ray image through the lowest point of the head of the(More)

A 3 x 2 to 5 x 3.5-cm fasciocutaneous flap from the radial aspect of the thenar eminence, located(More)
STUDY DESIGN An analysis of lateral radiographs in the upright, flexion-extension position. OBJECTIVES To document and define the differences in cervical flexion-extension kinematics as they relate to changes of alignment in upright cervical lordosis. SUMMARY OF BACKGROUND DATA No previous study has reported the association between sagittal plane(More)
BACKGROUND There have been no reports describing the results of conservative treatment of acute lateral ligament injury of the ankle in detail in terms of the severity of the injury, and the results of conservative treatment for injury with severe instability are still controversial. The purpose of this study was to assess the results of nonoperative(More)
