Ankle arthrodesis or Total ankle replacement?





It may be that you have known it or not, ankle arthrodesis is referring to fusion of our joint. This is including the process of gluing the related joint bones together using screw or any attachment methods that are available. This process will cause our joint to lose it normal upwards and downwards movement which surely disturb our daily walking ability. This will also increase the stress applied to the joint. Due to the fixation of the joint, it will leads to arthritis at the joint near to it that can cause more complication afterwards. This is one reason why Total Ankle Replacement becomes favorite among nowadays patients.

Experience will be needed in order to put in the implant nicely to avoid complication to the amputees in the future. Surgeon that have undergo many time of surgery will be better in completing the surgery process. This is important as different people will have different conditions and that is why there will be many variable to be considered during the insertion of the implant.

After receiving this implant, patients will be able to do their simple movements back. It is better to avoid activities that can overstress the joint. Patients can cycle, walk, hike, climb and even ski after the surgery and rehabilitation. They should avoid doing activities that can cause the joint to experience repetitive pounding and great stress such as running and heavy labor.

Good candidate for receiving this implant are those who are 50 years and over of age, not too heavy and not too active. Surgeons need to observe the receiver joint’s range of motion, having diabetes or not, nerve condition and bone quality. In some cases, arthrodesis is more suitable for patients as their range of motion of the joint is very small and they will less likely to realize the effect of arthrodesis to their joint’s movements. Diabetes and nerve condition need to be considered because they will affect the condition of the implant. Poor bone quality will disturb the performance of the implant and can cause loosening of the implant or broken of the bone.

After surgery, rehabilitation is very crucial so that patients can train they “new ankle joint”. After removing the surgery stitch, cycling and swimming can help to train the joint.

Hi,
I am also trying to complete my undergraduate dissertation on the design of ankle implants, yet my university has never done this before thus meaning i have no resources. I saw you had 3D cad models of the ankle joint, was wondering if you could maybe help me out.
thx
