Characteristics of the Skeletal System of Bound Foot: A Case Study

The purpose of this study was to establish the character of skeletal system of bound foot with binding deformity. Medical images were taken with a slice distance of 1mm from CT equipment. 3D models of bound foot were developed using density segmentation techniques through Mimics software. The talocalcaneal angle, calcaneal-first metatarsal angle, talo-first metatarsal angle, hallux valgus angle, I-II inter-metatarsal angle, I-V inter-metatarsal angle, first cuneiform-metatarsal angle, the horizontal metatarsal angle and the length of five metatarsals were evaluated on the lateral and antero posterior view. The results showed that bound foot have great deformation on the second to fifth toe, forming the abnormal higher foot longitudinal arch. The potential formation process of foot deformity associated with the binding process and its influence on the daily life of the foot binding subjects is discussed.
