Orthopaedics: as an ancient discipline concerning bones, joints, muscles, tendons and nerves-the skeletal system, has been developing rapidly since more and more progresses in theory and improvements in technology have been employed in orthopaedic practices. A variety of subdisciplines, such as hand surgery, spinal surgery and hip joint surgery, have emerged to meet the demands by the development of special services in the field of orthopaedics. However, the basic conception remains consistent in the principle of diagnosis and treatment of orthopaedic disorders. Taking the clubfoot treatment for an example, the prevailing protocol of surgical treatment is to achieve one-stage correction of all the components of the deformity relying on three-dimensional analysis within the time frame of an operation［1］. The diagnosis aims mainly to identify the pathologic morphology and the related factors, even in terms of three-dimensional architecture, signal transduction at the molecular level and the biologic activity［2-7］. Nevertheless, little is known about the adjustable means and predictable situation for the process of disorder and treatment planning.
