This is a very good question but in order to answer it more information is needed regarding the cause of nerve damage and muscle atrophy. Is it because of trauma, congenital or hereditary? is it stable or progressing? is it affecting one or both legs and does it affect you activities and mobility. Calf augmentation with implants is a good solution to cosmetically correct muscle atrophy caused by many neurological problems such as spina bifida, club foot, trauma and few others. I've done many of these using standard and custom-made implants and patients are usually very happy with the outcome. However, you need to be very cautious in assessing the risks and benefits in some cases when you have a borderline or limited mobility. Surgery can affect the limb function. Sometimes recovery of mobility can't be 100% to the level of function before surgery. If a patient has a borderline motor function and just about manages to cope, surgery can tip the balance and render them permanently imobile or disabled. Therefore it is very important that your plastic surgeon has the experience dealing with these cases, he/she knows your condition very well, and seeks the opinion of the doctor treating your leg condition (neurologist, neurosurgeon, or orthopaedic)
