Abstract:All kinds of diseases or injury involving the extremity might lead to its deformity with disability of the patient. In the past, more attention was paid to the correction and functional compensation of the limb deformity only, which cost a lot and had a poor effect. In the past decade, the general notion of limb deformity correction has been constantly updated, with more emphasis on the correct treatment and rehabilitation of primary disorder and injuries to prevent deformity early. In addition, the idea has been put up, including the early de- tection of malformations and early intervention, regaining the joint stability and range of motion, as well as reconstruction of ligamentous sta- bility and muscle balance on the basis of restoring the normal alignment of the limb, and the combination of various surgical corrections with patients' active participation in rehabilitation. This paper reviews the causes, evaluation, correction principles and treatment options of lower limb deformities, and gives a brief introduction of the works of the Orthopaedics and Rehabilitation Committee for Physical Disability, China Association of Rehabilitation of Disabled Persons in the past ten years.
