Information for Professionals

The following are three case studies of interest for professionals involved in care for the amputee patient, illustrating the complexity involved in good sound prosthetic care. If any attention to detail is overlooked, the patient will never reach their full potential, and that is unacceptable. Although all prosthetic cases are complicated, some are more easily managed due to lower activity levels or healthier bodies in general.

A successful prosthetic case occurs only when the patient feels they are restored in function. This means they have the ability to be fully active in their life, in the most practical, comfortable and secure way. This will be their prosthesis and it should be made by blending their individualized needs with our professional expertise.

 If I can ever be of help, please feel free to contact me for a consultation any time.
