AI Technical Summary
In clinical practice, when the patient stands, X-rays emit an x-ray obliquely downward, resulting in the X-ray imaging plate being unable to fully image, and the X-ray film of the hindfoot force line cannot be successfully taken, and the appropriate measurement device is lacking to adjust the inclination angle of the X-ray imaging plate and the X-ray imaging plate.
A rear foot force shooting platform at a specific angle was designed. The platform is made of non-metallic materials to avoid blocking X-ray imaging, and an inclination measurement mechanism is set on both sides to quickly adjust the inclination angle and vertical relationship between the X-ray source box and the X-ray imaging plate. The platform also raises the foot height and the horizontal position is adjustable so that the irradiated area of the X-ray falls on the X-ray imaging plate.
Through this shooting platform, the image data of the hindfoot force line at a specific angle can be obtained more completely, which solves the problem of X-ray imaging incompleteness and simplifies the angle adjustment process.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of orthopedic imaging auxiliary tools, in particular to a hind foot force line shooting platform at a specific angle. Background Art
[0002] Hindfoot varus is defined radiographically as a deviation of the calcaneus relative to the longitudinal axis of the tibia. Varus malalignment shifts the axial load laterally compared to neutral alignment, which subsequently creates a varus moment that can lead to an ankle sprain if not corrected at foot strike. One of the commonly used 2D measurements of hindfoot varus is hindfoot alignment, which is derived from a coronal view of the hindfoot. Hindfoot alignment represents the relative position and orientation between the calcaneus and tibia, and hindfoot varus occurs when the nadir of the calcaneus is medial to the tibial axis.
[0003] Hindfoot inversion is one of the manifestations of abnormal force line of the lower limbs. When hindfoot inversion occurs, it will cause abnormal force transmission in the ankle joint, which is prone to ankle sprain and ankle instability, and then develop into ankle osteoarthritis, and even cause abnormal overall force line of the lower limbs. Early detection and evaluation of hindfoot inversion has always been difficult, and measurement of hindfoot force line is an important basis. The anteroposterior radiograph of the lower limb will have overlapping bone structures and cannot be measured, so it is necessary to take an X-ray at an angle of about 20° downward.
[0004] However, in actual clinical work, when the patient stands on the ground and the X-ray source box emits X-rays obliquely downward, the X-ray imaging plate cannot fully image, resulting in failure of hindfoot force line imaging. At the same time, there is a lack of corresponding measuring devices for adjusting the tilt shooting angle of the X-ray source box and the X-ray imaging plate, and the X-rays emitted by the X-ray source box must be kept perpendicular to the X-ray imaging plate, resulting in difficulties in performing X-ray imaging of the hindfoot force line at a specific angle (20° obliquely downward).
