LOW COST LASER ALIGNMENT SYSTEM: A NEW APPROCH

Kumarpal Singh* and Smita Nayak

ABSTRACT

The alignment instrument is a prime importance of the fabrication of orthosis and prosthesis. Usually in Lower Limb Prosthesis Plumb-bob is used as a weight bearing line. It helps to check the Anterior-posterior and Medial-lateral static bench alignment but It need much more experience and skill to handle a plumb-bob for alignment and it does not provide an exact Angular relation ship between socket and pylon (socket extension piece). To overcome this accuracy and angulations factor the laser beam Laser Aligner is introduced. These types of aligner provide accuracy in linear and angular relation between prosthesis assemblies. Most of Laser aligner cost between Rs. 25.000 to 2, 00,000. It is an effort to achieve Function in prosthesis and orthosis by aligning with low cost and minimum technology applied aligner to improve quality of life of patients.

Keywords: Anterior-posterior, Medial-lateral, prosthesis and orthosis.
