The development of a prototype patella tendon bearing prosthesis using high-density polyethylene piping (the drainpipe leg).
In Nepal, the few centres that offer a lower limb prosthetics service generally use a laminate of polyester resin with cotton stockinette in the manufacture of the hard socket and cosmesis. Until 1989 this was also the only process used at Green Pastures Hospital in Pokhara. In response to a materials shortage brought about by a local international trading dispute, however, a prototype patella tendon bearing prosthesis was developed using high-density polyethylene piping. The terrain of Nepal, local walking habits, and therefore expectations of a prosthesis, differ considerably from those in the United Kingdom; hence some unusual design requirements are needed to be taken into consideration. This paper describes the progress of the design over several months and the constraints under which the work was carried out. Feedback was sought at the meeting at which the paper was presented, and would also be valued in response to this written account of the work.
