Inventions and creations by Dr L.Prakash

Congenital pseudoarthrosis of the tibia is a difficult condition to treat indeed. I invented the Prakash bangle fixator in 1996. Though this was not my first orthopaedic invention, it is one that I am REALLY PROUD OF!!

In those times young children with congenital pseudoarthrosis of tibia underwent and early amputation and a prosthesis to allow them to walk when they should..

I made a change in the rule book, and now it is the standard method.. It is besides the point, that I have been given no credit..


Parents of at least eight children treated by me have named their children Prakash. This really humbles me!!


Other mundane orthopaedic inventions were

High flexion hip replacement

India's first total knee replacement

India's first total knee replacement

( I even started a company Innovation Mediequip limited to make these knees. I was arrested, I was swindled of the company, someone impersonated me, changed the name to Invicta Mediteh limited, and then sold it to TTK pharma. My invention is now being sold as the Altius Knee.. It is priced at 10 times what I wanted it to be priced for Indian patients!! I feel sad. Poor patients fall prey to the greed of multinational companies.)


Madras Modular hip instrumentation


Prakash Knee instrumentation


Spine retracter


India's first pneumatic drilling and cutting orthopaedic tools


Prakash endoscopic bone nibbler

and some trivia that makes the surgeons life easier


Praklay is a unique invention, invaluable for artists, sculptors, modellers, jewellers, creators, designers, miniaturists, and scientists.

Comparable international brands are six times as expensive and need ovens to bake it to plastic hardness.
