Introduction

      There have been various improvements in the design of the elbow prostheses to meet the current demands. Many people have lost their limbs or arms due to accidents and therefore leading to the development of artificial limbs to help the victims work and ensure they are moving on with their lives. The prostheses designed are of different types and are classified as the linked and the unlinked. These technology has helped a lot globally and has served the people who need them a great deal (Pjetursson, 2012).

      For the valid comparisons to be made between the various types of implants used for the total elbow replacement a classification mode system is required to achieve this (Pjetursson, 2012). The rating of this device is solely upon the degree of resistance to movement such as the constraint and unconstraint which states that the articulating surfaces offer no resistance to movement just as the term implies. However, the device can be classified into other two major groups such as the linked and the unlinked. We can define linked components as those offering resistance to distraction which includes the snap fit design of the Prostheses. The two broad groups can also be sub-divided further into various groups such as the congruous and the non-congruous designs depending on the shape of the articulating surfaces of the Prostheses.

         During the transfer and the use of the precommercial arm, a technical problem comes up when attempting to fit the first five of the made elbow prostheses. This brought a lot of unbelief to the market and perhaps the target group in the clinical facilities. This resulted to the hold off further production from the technological firm to reevaluate and incorporate design improvements (Pjertursson, 2012). The changes were made, and this led to the other trials of the improved elbow prostheses equipment. This success resulted in the market boost of this design and hence a high demand from the population at the clinics. Moreover, the technology was also available to other construction firms which use the bulldozers for extraction.

       The operation of the designed arm prostheses required an intensive guidance from the providers. This involves the written documentation of how to use the product and also training sessions to the clients to ensure they have clearly understood the factors and the rules for the use. This documentation also involves in the maintenance and repair of the arms. In the event of the malfunction, the designated field investigator known as the PI was instructed to look after the performance of the product. The guidance document involves the following outlines; the instruction video, cable routing and adjustments, slack cable and its functions for use and the artificial TD tensions. This instructional document helps to improve the efficiency of the design to the clients and improve the marketability of the machine since the customer can use the product easily.

                                                                                   Conclusion                                    

         The custom prostheses designs company provides prosthetic alternatives to assists reconstruct a surgery for both the parents and even children who have deformities either in the ear, the eyes and other parts (Pjetursson, 2012). Apart from the elbow prostheses we have the artificial eye prostheses for patients with eye problems, we have the finger prostheses for replacing the lost fingers, and lastly, the ear and microtia prostheses that enable the clients to get their lost ears. The developments of the other design have allowed the victims from the accidents to get back something that they lost. In conclusion, the development of different prostheses should be encouraged and the government to subsidy the prices to make them affordable even to the middle class. The providers should also increase the efficiency of the products.
