Objective: To investigate the clinical effect and feasibility of pyro-thermoplast knee-ankle-foot orthosis(KAFO)on rectifying slight to middle rage genu varum and genu valgum of children rickets,through analyzing the angle change of 12 knee joints after wearing the special-made pyro-thermoplast KAFO. Methods: We designed and specially made pyro-thermoplast KAFOs for 7 patients,12 abnormol knee joints,asked them to wear for at least 18 hours per day even when standing and walking,and executed a 1 to 6 months follow-up,measuring femorotibial angle(FTA),thigh and shank side bow angles before and after the wearing. Results: Femorotibial angle, thigh and shank side bow angles are not different when comparing before wearing and 1 month after,but statistically different between before,3 months after and 6 months after wearing respectively. Conclusion: Pyro-thermoplast KAFO has a great effect on preventing and rectifying slight to middle rage genu varum and genu valgum of children rickets.
