Background: Scoliosis is a sideways curvature of the spine that occurs most often during the growth spurt just before puberty, which posses a postural disorder to individuals and also makes them walk with pain.Aim: the aim of this study is to design and develop a mechanical bed-system that will be used to conservatively mange adolescent scoliosis effectively and efficiently by reducing cobb angle and pain.
Materials and Methods: materials needed are; Orthopaedic bed, Metal bars, Orthopaedic Foam, Fabrics, Metal pads, Metal bolts and nuts, Metal pipes. The methods followed are; fabrication of six-spring patient’s bed with the metal bars and then fixing six-spring foam on the bed. It was followed by fabrication/formation of metal pads for application of force on the patient’s spine, while lying down on the bed-system and then attachment of the foam pads to the metal pads. Three stands with a bolt and nut for attachment of the metal pads were fabricated and the components were fixed together.
Result: the mechanical bed-system comprised of a metal bed, mattress, counter pressure pad, adjustable screws and metal stand.Discussion: although, bracing, casting and physiotherapeutic manipulations can reduce the cobb angle of scoliosis over a period of time (months), it is now believed that this device had given rise to a new technology that can stop and also reduce scoliosis curves more effectively and efficiently. Conclusion: The mechanical bed-system exerts more and tolerable pressure to the spine than the bracing, hence a better outcome.
