I turn 80 in three months and failed to get hip replacement for the 4th time always for a simple reason and this time on the off chance that one of my 8o year old teeth might cause an infection and affect the new hip. In the meantime my hip moves up a little more causing some interesting things to happen. As a result I began doing research on alternatives and it is amazing to see the advances in Robotic Orthosis combined with advances in medical alternatives. My main concern is not to get any worse and the possibility of ending in surgery because of a fall. I will be contacting groups that are creating these wonderful attachments to discus ways to adapt skeletal units to not only relieve the need for replacement but to help individuals that have lost the hip regain mobility and a normal life of mobility. Would like very much to work on this with anyone interested and sharing what I find. Marty
