INBONETM Total Ankle System FAQ’s

  • What is Rheumatoid Arthritis?
  • Rheumatoid arthritis occurs when the body’s own immune system attacks the synovial lining of the joints, just as it would a foreign bacteria. Synovial fluid is clear, smooth oil-like lubricating liquid that makes it easier for the joints to move.

  • What is Tarsal Tunnel Syndrome?
  • Tarsal Tunnel Syndrome is the result of the nerve compression in the ankle as the sensory nerve passes under the tarsal tunnel and the tunnel is irritated by pressure. The result is numbness and tingling in the foot and ankle.

  • What is Ankle Injury?
  • Ankle injury occurs when there is trauma to the joint. Symptoms include swelling, pain, weakness and difficulty walking. These injuries can significantly affect your mobility.

  • What are the benefits to Ankle Replacement?
    • Enhanced fixation
    • Bone preservation
    • Multiple modular components to assist in anatomical sizing
    • Thick poly insert for maximized resistance to wear
    • Allows patients to maintain an active lifestyle
  • Total ankle replacement is a viable surgical solution for pain reduction in the joint. It is a bone-conserving, less-invasive approach than in the past.

    The INBONETM System has been designed to fit your specific anatomy because it is supported by an adjustable length stem and a fixed bearing system for enhanced fixation. The vertical fixation of the implant allows less bone removal and leaves the fibula completely intact. The talar component maximizes cortical bone support to minimize talar subsidence.

  • Is Total Ankle surgery a new procedure?
  • Ankle replacement has been around for many years. Using design elements already proven successful in hip and knee implants, INBONETM Ankle engineers designed total ankle replacement that could replicate natural anatomy.

  • What makes an INBONETM Implant different from others?
  • The INBONETM Ankle modular design feature of the tibial stem allows the surgeon to select the appropriate number of pieces based on patient size and bone structure. This results in a more precise fit and less-invasive installation process with minimal bone removal. Other procedures offer only stems available in specific sizes which does not allow a customizable fit.

    The patented FootHolder secures your foot but the ankle remains dynamic. Guide rods determine exact alignment allowing the surgeon to precisely position the prosthesis. No other ankle implant utilizes this type of installation guidance.

  • What age is ankle replacement an option for me?
  • Patients aged 30 to 75 have received total ankles. We will need to examine you to see if you qualify.

  • Is the INBONETM Ankle a viable option for revision of other failed total ankles?
  • Yes, the INBONETM Total Ankle can be used to replace other failed total ankles.

  • What are possible complications?
    • Breakage of implant or loosening the bone due to improper position
    • Loosening or dislocation of implant due to trauma or loss of fixation
    • Pain in operated area joint
    • Damage to blood vessels
    • Temporary or permanent nerve damage resulting in pain or numbness of the affected limb
    • Cardiovascular disorders including venous thrombosis, pulmonary embolism or myocardial infarction
    • Hematoma
    • Delayed wound healing
    • Infection which could necessitate removal of the prosthesis
    • Implant removal or replacement due to bone resorption around implant
    • Allergic reactions or metal sensitivities
    • Bone damage or fracture during installation due to compromised bone quality, osteoporosis, or previous bone injury or surgery
  • Possible adverse affects of surgery include:

  • What do I need to do at home to prepare for discharge?
    • Moving wires and cords to prevent tripping
    • Removing small throw rugs
    • Selecting a stool or chair for elevation of the ankle
    • Taking precautions in your shower or bath to prevent slipping
    • Adjusting the height of chairs and furniture
    • Asking for assistance with transportation
  • We will give you detailed instructions before you are discharged from the hospital. These may include:

  • What should I expect in the immediate post-operative period?
  • In the immediate post-operative period, you can expect swelling and some pain. We will prescribe medications to keep you comfortable and prevent infection.

  • Do I need to take precautions before dental work?
  • It is important to inform your dentist that you have recently undergone total joint replacement surgery. If bacteria in the mouth travels into the bloodstream, it could increase the likelihood of infection of your total joint replacement.

  • Why do I keep setting off the airport metal detector?
  • Your total ankle replacement is made of titanium and cobalt chrome; two metals that can set off security screening machines. If you are a frequent traveler, you will need a product identification card to carry in your wallet and display at security checkpoints.
