The Morphology And Imaging Features With Correlation Of Osteoporosis Research Of Foot-binding Deformity In Yunnan, China

Objects:Analyzing the type, pathological features, the morphology and imaging features and correlation of osteoporosis of foot-binding deformity; Establish the database of foot-binding deformity in Yunnan Province; Establishment the digital three-dimensional computer model of calcaneus in foot-binding deformity to provide restoration of calcaneal morphology objective anatomical reference for clinical cases of foot-binding deformity calcaneal fracture surgery.Methods:308 women of foot-binding and non-foot-binding from Sancha River Town, Luliang County, Yunnan Province were randomly selected, whom to check the calcaneus bone mass density and measure the height, weight, waist and hip circumference. In which 204 casses is foot-binding group, aged 65-88 years old, mean 76 years old;104 cases is non-foot-binding group, aged 64-87 years, mean 73 years. Randomly selected 102 cases from the 308 cases for DXA lumbar spine and hip measurement, in which foot-binding group of 56 patients aged 67-85 years, mean 74.8 years; non-foot-binding group of 46 patients aged 66-85 Years, average 72.5 years old. And then randomly selected 67 cases from 102 cases for CT scan and feet orthotopic and lateral X-ray examination. In which foot-binding group of 54 patients aged 67-82 years, mean 74.6 years;non-foot-binding group of 13 patients aged 68-85 Years, average 73.4 years old. And then through X-ray, CT post-processing workstation to system test results measurement, and analysis of measurement results.Results:1. The morphology characteristics of Foot-binding deformity:â‘ the foot is triangular-shaped, and the front foot is small,looks like the cone. The heel is hypertrophy and nearly circular;â‘¡second to 5th toes is bent inward at the sole of foot, the forefoot is squeeze to move closer to the heel, there is a transverse hollow in the middle of foot,5th foot is always pressed in this depression;â‘¢the arch of foot is higher, dorsum of foot is eminence, forefoot is obviously plantar flexion;â‘£the foot-binding deformity is significantly smaller than the normal one.2.Analyze the results of X ray measurement can be seen, bind up our wounds after the foot-binding by arch feet structural damage, the three cuneiform bone of foot, foot navicular, cuboid, talus and calcaneus have different levels of wedge changes and lines of force of the tarsal bones were significantly changed. With the angle of tibia, Hibbs angle, M'eary angle, talocalcaneal angle and angle change from the post-tibial see the arch at the same time raise the front of the calcaneus and the talus upward, so that after the calcaneus by the trochanteric to become the lower edge of the edge of the ground after trochanteric, this change is conducive to risk due to the arch of the heel caused by the disappearance of the surge load; while the foot after foot-binding force structure into a three-point after calcaneal tubercle first metatarsal edge and force base two point, and the calcaneus as a weight-bearing body when walking and standing.3. After compare CT measurements, we can see, after squeeze of the tarsal bone, wedge and arch elevation changes, leading to the front of the calcaneus, body growth restriction, than those non-foot-binding bone atrophy were shorter, narrower. Posterior calcaneus (intertrochanteric) and the Ministry of sudden load from the body due to the need bear the pressure of weight-bearing and walking, so those are basically the same, change is not obvious. The calcaneal thalamus constitute Gissane's angle and the main basis for Bohler's angle, we can see the front of the calcaneal growth retardation, atrophy, leading to significantly different in Bohler's angle; but no significant effect on calcaneal groove, thalamus development, so Gissane's angle was no statistical difference. 4.With age growing, the foot-binding group and the non-foot-binding group calcaneus bone mass density decreased, indicating the increasing incidence of calcaneal fractures, and the risk of fractures of foot-binding group significantly higher than the non-foot-binding group.5.By age group, there were no significant differences in lumbar spine and hip T values between the foot-binding group and non-foot-binding group. The lumbar spine, hip bone mineral density of foot-binding group and non-foot-binding group was almost the same. Lumbar spine and hip fracture risk of foot-binding group and non-foot-binding group was almost the same.Conclusion:1.Systematic analyze the morphology and imaging features of foot-binding deformity in Yunnan, China; built a database of foot-binding deformity in Yunnan, China; fill the foot-binding deformity of the many gaps at home and abroad.2.Through the measure of the calcaneus in anatomy, establishment the digital three-dimensional computer model of calcaneus in foot-binding deformity. Which for clinical cases of foot-binding deformity calcaneal fracture surgery designed to restore the calcaneus shape to provide an objective and accurate reference.3. Analysis the correlation of osteoporosis and the fracture rate of the parts which are easy to have fracture between the foot-binding and non-foot-binding women.
