PROSTHETICS

A prosthesis is a custom designed and custom fabricated device to help restore function, mobility and/or cosmesis for an amputated extremity. In the case of a lower extremity prosthesis, the restoration of the ability to ambulate (walk) or transfer independently is normally the first priority. In the case of an upper extremity prosthesis, the ability to improve function of bimanual tasks and daily activities is of primary concern with cosmesis often competing for equality on the priority sequence.

Every amputee has unique goals, needs, motivations, strengths, and physical attributes and therefore every individual is carefully assessed at the onset of the process to ensure these considerations are factored into the prosthetic treatment plan.  This greatly improves the ability to properly select prosthetic components that are well suited to each individual patient.

Following a patient interview and assessment, a casting and measurement takes place to obtain a negative impression of the residual limb. This mould is used as the starting point for the prosthetic interface, which is called the socket. Once the socket is fabricated, it is mounted onto the prosthetic componentry selected. Once the device is ready, an initial fitting appointment takes place. It is very common to bring the device home during the fitting process, for a "trial" period. This allows the amputee to determine whether or not the socket is fitting optimally, before moving on with cosmetic finishing of the device. Once both the patient and prosthetist are pleased with the fit and function of the device, the final stages of fabrication take place to produce a "finished" prosthesis.

The most common levels of amputation seen in prosthetics include Trans-Tibial (Below-Knee), Trans-Femoral (Above-Knee), Symes (Through the ankle), Partial Foot, & Trans-radial (Below-Elbow). There are many other levels of amputation, and Sudbury Prosthetic & Orthotic Design Ltd will be capable of fitting all levels, all ages, and all activity levels including high end athletes. We are also qualified to incorporate a wide range of current technologies into the prostheses we design, such as myoelectrics for upper extremity amputees, microprocessor knees (C-leg) for above-knee amputees, and elevated vacuum suspension methods such as the Harmony system or Limb Logic VS for lower limb prostheses.
