The present method of static three point bracing is unsatisfactory. The static type orthosis becomes ineffectual in reducing flexion deformities in upper and lower extremities and requires constant adjustment as the contractures are reduced.
A three point dynamic orthosis using a flexible rod construction has been designed to contain and reduce flexion deformities. This orthosis has certain advantages over the static type and has been used successfully in children with contractures due to cerebral palsy and burns.
