Vulcanized rubber foot for lower limb amputees

The purpose of this study was to examine the outcome of the application of the High Density Polyethylene (HDPE)-Jaipur prosthetic construction in fitting trans-tibial amputees in a number of projects in the developing world. Projects in Honduras, Uganda and India were visited. Three hundred and twenty (320) patients had been provided with a HDPE-Jaipur prosthesis and of these 172 were seen for a technical and clinical follow-up after a median of 35 months. More than half the amputations were due to trauma, the remainder to disease. Fabrication and fitting in the three projects was carried out by individuals who had undertaken a twice week training course provided by Bhagwan Mahaveer Viklang Sahayata Samiti limb centre in Jaipur. The individuals involved had limited background training in prosthetics. Craftsmanship and fit were assessed as being poor in 56% of cases. The technical quality of the Jaipur foot was considered acceptable as its performance was better than previously observed results. Although there was patient satisfaction of 85% and compliance of 94% the HDPE-Jaipur trans-tibial system was not considered acceptable as 49% reported walking distances less than 1km and 36% 'discomfort. The major inadequacy in outcome relates to the use for fabrication and fitting of individuals with inadequate education and training.

“…In the 1970s, Dr. P. K. Sethi initiated the development of a prosthetic foot being an alternative to the conventional SACH foot, but which allowed barefoot walking, squatting and cross-legged sitting (Sethi et al 1978). The foot was originally designed with a high ankle block of wood facilitating fixation to the aluminium shank of the prosthesis with wooden screws; a block of sponge rubber layers glued together to resemble the mobility of the normal ankle, subtalar and mid-tarsal joints.…”

“…S. Jensen & W. Raab such as the VI-Solid and VI-Cavity Heel feet from Vietnamese Veterans of America Foundation, Kien Khleang, Cambodia and the EB-1 foot from Prosthetics Outreach Foundation, Vietnam even when exposed to barefoot walking. The high number of heel block related failures with the Jaipur feet indicates that the problem is of technical nature, and that the separation and sliding between the sponge rubber plates does not have the advantage praised by Sethi et al (1978).…”

Clinical Field Testing of Vulcanized Jaipur Rubber Feet for Trans-Tibial Amputees in Low-Income Countries

The purpose of this study was to check out the performance and durability of vulcanized Jaipur rubber feet in tropical areas of the developing world. Forty-one MUKTI and 40 NISHA feet were followed for 16 (8 - 17) months. The user compliance was high and nearly all were satisfied. Failure of the prosthetic foot with the need for exchange at the end of the study amounted to 27% (22/81), which is equivalent to a mixed series of rubber feet previously reported (Jensen et al. 2006b). Failures were mostly related to skin fracture and gliding between sponge rubber layers of the heel block.
