Introduction

  • Limb replacement surgery involves the attachment of prosthetics where there are no natural limbs
  • At Orthopaedics India, amputation reconstruction specialists use the process of osseointegration to attach limbs

About Osseointegration

  • Bone ingrowth into a metal implant – scientifically known as osseointegration
  • An artificial limb surgically anchored to the remaining bone so that it integrates and grows into the implant
  • For instance, even dental implants apply osseointegration, just like joint replacement surgeries do
  • The procedure has been used for decades and deemed phenomenally successful

Limb Replacement

Limb replacement

  • A porous, titanium implant used to align the prosthesis with the residual stump
  • After that, the implant – then directly inserted into the bone
  • Transtibial or below the knee osseointegrations involve:
    • Tibia or leg bone
    • Femur or thigh bone
    • Radius and ulna or forearm bones
    • Humerus or upper arm bone

Candidates for limb replacement

  • Potential candidates for limb replacement are primarily amputees
  • There could be others who have had poor prior experience with socket prosthetics
  • With wide, short, scarred, or painful, residual limbs, socket prosthetics tend to fail

Advantages (traditional surgery vs. osseointegration techniques)

Traditional residual prosthetic leg systems

  • Generally, traditional procedures, unsuccessful because they fit poorly across the limb and socket
  • This is due to significant changes in the shape and size of the socket after amputation, which takes around 12 to 18 months
  • Additionally, uneven angles may result in malalignments – causing problems with gait, balance, and energy transfer issues
  • Common problems associated with a traditional ball and socket techniques:
    • Sweating, pinching, poor fit, skin irritation, ulcers, and sores
    • Also, the lack of patient confidence due to challenges with mobility

Osseointegration techniques

  • Patients with osseointegrated limbs display better control their prosthetics
  • Besides being physically attached, the prosthetics become emotionally attached as well
  • Direct connection with the remaining limb ensures high levels of strength and stability
  • Proprioception or osseoperception of prosthetic limb – dramatically improved
  • Touch vibrations of the implant transferred to the individual’s natural bone
  • Furthermore, the upper limb movement along with gait – improved

The surgery

  • At Orthopaedics India, precise measurements are obtained before the surgery
  • CT scans and Side-view X-rays, also taken
  • Consequently, a custom-made implant then built to fit into the residual bone
  • An interdisciplinary team of highly qualified surgeons, prosthetics professionals, anaesthesiologists and nurses work together to ensure best outcomes
  • Likewise, expert opinions of physical and occupational therapists obtained

Most of all, to ensure that your prosthetic performance is at its best, reach out to skilled surgeons at Orthopaedics India for advice.
