Abstract :

Aim: To compare manufacturing cost of Laminated and Modular Transtibial (TT) Prosthesis for Below Knee amputation. Methods: A prospective randomized controlled study was conducted for 30 unilateral Transtibial (Below Knee) amputees at Government run Rehabilitation Institute, Chennai between Jan 2017 to Dec 2017. 15 were randomly assigned to Laminated and 15 to Modular TT Prosthesis group and manufacturing cost of prostheses calculated. Cost analysis included faication time, material costs, wages lost by patient while procuring the prosthesis and wages of prosthetist. Results: Total cost of Modular TT Prosthesis was Rs 11550 ±275.68 compared to laminated variety Rs 10908 ±843.22 (p=0.02). Even though this cost difference is statistically significant, modular variety is only 1/10th costlier than laminated variety. Production time for Modular TT Prosthesis was 1 day compared to 5.8 ±0.421 days (p < 0.01) for Laminated variety. Conclusion: Cost of Modular TT prosthesis is not very expensive and delivered faster compared to Laminated variety, hence economically viable in a government run artificial limb center.
