About Creative Orthopaedics

Creative Orthopaedics LLC is owned and operated by John R Pepper. After 19 years of corporate R&D experience, John founded Creative Orthopaedics to allow him to focus full time on the advanced stages of implant design. John's time as an experimental surgeon on a canine project funded by BioElectron taught many lessons of the reality of performing survival surgery. As a result, he has a unique appreciation of the challenges faced in the operating room.

TriGen Design Engineer.         Titanium nail system                    ~$100MM annual sales

TriGen is a comprehensive lower extremity fracture treatment system. Seven fracture classes are treated

with tools contained in one instrument case. A new entry and bone manipulation technique are the main

reason the TriGen system can reduce OR time by approximately thirty percent. Reception by hospital

staff and sales representatives has been outstanding. Primary design surgeons were Toney Russell, MD

and Roy Sanders MD. I was the main engineer on the team that developed the system. There are

numerous patents filed on designs for this, see the patent section.

TriMax Design Engineer         Modular Intramedullary Nail            Clinical trial 1994-1996

TriMax is a modular Intramedullary nail designed to reduce inventory required to repair femoral neck and

shaft fractures. The Health Care market of the early nineties demanded a system that was going to cost

much less than the one piece nails used to that point. Over one hundred nails are implanted. Improvements

 in the market place have halted full release of TriMax. Much instrumentation and several design features

were carried over to the TriGen system.

 

Conducted cadaver studies to justify design changes in the implant design. Full design responsibility.

 

Product, sales, and  marketing support of existing products. Heavy surgeon interface.

 

Proven Ability: Innovative Product design.
