Description

Adjustable foot limiter

Technical Field

The utility model relates to a medical science image auxiliary instrument field specifically is a foot stopper with adjustable.

Background

Osteoporosis (osteoporotis) is the most common skeletal disease, a systemic disease characterized by low bone mass, damaged bone microstructure, increased bone fragility, and susceptibility to fracture. In 2019, the prevalence rate of osteoporosis of people over 50 years old in China is 20.7% for women and 14.4% for men; the prevalence rate of osteoporosis of people over 60 years old is obviously increased, and women are particularly prominent. Dual-energy X-ray Bone Mineral Density measuring instrument (DXA) and quantitative CT are the main methods for measuring Bone Mineral Density (BMD), wherein DXA is the "gold standard" for diagnosing osteoporosis, and the present clinical dual-energy X-ray absorption method for determining BMD has the advantages of high accuracy and precision, low radiation dose, convenient operation, etc., and the main measurement site is the middle axis Bone, including: the proximal lumbar and femoral measurements are limited, and the distal non-dominant radius 1/3 (33%) may be selected. The DXA orthoscopic lumbar measurement region of interest includes the vertebral body and its posterior appendages, so its measurements are affected by degenerative changes in the lumbar spine (e.g., osteoproliferation of the vertebral body and facet joints, etc.) and by calcification of the abdominal aorta. DXA proximal femur measurements of bone density in the regions of interest were femoral neck, great tuberosity, total hip and Wards triangle, respectively, where the regions of interest for osteoporosis diagnosis were femoral neck and total hip. The positioning of the lumbar spine is not difficult under normal conditions, and sometimes happens when the age is increased or when certain diseases cause hyperosteogeny and calcification of intervertebral discs and adjacent tissues, the BMD value of the lumbar spine loses reality, so that the measurement of the hip bone becomes an alternative position. The femoral neck of the elderly and climacteric women is a part which is easy to fracture, so the significance of the femoral neck is obvious. However, there are many factors that affect the measurement result in the actual use process. How to accurately assess the degree of leg rotation is a current clinical difficulty.

Although there are leg fixing devices, such as trapezoidal and triangular foot positioners, due to age, height, weight and difference in selected measuring parts, the measured value is more true than the true value, which has negative effects on diagnosis and treatment. Rotating the entire leg of the patient (from the patella to the foot) inward by 25 ° has a significant effect on hip bone density values, which can lead to more realistic values of the measured values being abnormal, negatively affecting diagnosis and treatment. For a clinician, it is important to accurately assess the osteoporosis level of a patient by rotating the entire leg (from the patella to the foot) of the patient 25 ° inward using the fixator (brace) in the absence of other imaging data.
